ProMix series are in-line or make-down polymer preparation stations. Using a variety of pump technologies, the liquid polymer is metered into the multi-zone mixer unit to the diluent water and processed into a homogeneous and effective polymer solution. The unique mixing regime delivers a highly activated polymer solution to every application with optimum performance.

With Ultromat continuous preparation, the reservoir is separated into multiple chambers. Thus, it is extremely unlikely that recently mixed polymer gets into the suction area of the metering pump (product entrainment). An economical means of polymer preparation with a much smaller footprint than a batch based system thus being a suitable retrofit for existing polymer equipment.

would get reduced to MOE guidelineswithin the short distance between thetrack and the unfortunate nearby cot-tagers. The Ontario MOE regulation fornoise in a rural setting is 45 dB, measuredat the nearest receptor (listener’s) prop-erty line. (Typical human conversationlevels measure around 40 dB)

It is also suspected that the racetrack ishaving a deleterious effect on water qual-ity. At an association meeting, we wereshown a video of a downstream plume ofsand and dirt in the water, which is thesuspected result of race track erosion. Thisplume is continually working its waythrough otherwise pristine wetlands andinto a popular cottage lake.

To be sure, the impacts of a single rockcrushing operation and a single racetrackare only felt by a relatively small numberof individuals. However, the bigger issue,which council seems to have missed, isthat by approving such activities withoutrestriction it has set precedents for poten-tially dozens of similar facilities to be lo-cated within its boundaries.

To be fair, there are many governmentinitiatives, such as septic system regula-tions, and shoreline construction setbacks,which have helped cottagers preserve lakewater quality. The Ontario Ministry of theEnvironment will provide cottagers withSecchi disks which help determine algaelevels. The Secchi disk, a black and whitedevice named for Italian physicist PietroAngelo Secchi, offers a simple way oftesting a lake for oligotrophy (too few nu-trients), mesotrophy (more nutrients) oreutrophy (too many nutrients).

Residents are encouraged to use themto monitor lakes in the area six times aseason, from May to September, and toreport their findings. To use the disk,which measures 20 centimetres in diame-

Despite the drastic impact localdecisions can have on individ-uals, only 38.6 percent ofthose eligible to do so voted

during Ontario’s last municipal election.This is indeed tragic, because voter apathypalpably makes it much easier for an in-fluential few to lobby politicians, andpush forward their own agendas. As manyhave found out, it would have been mucheasier for them to contribute to any de-bate, prior to a decision, than to try andhave it overturned after the fact. As thesaying goes, “an ounce of prevention isworth a pound of cure.”

Recently, I was appointed to our cot-tage association board. Called Clear Lake,its very name conveys an image of cleanclear water, surrounded by a pristineshoreline. Generally, this is the case.However, seemingly innocent decisionsby our municipal council to approve arock crushing facility and more recentlya motorcycle race course are having far-reaching implications for residents andcottagers in the whole township.

Noise, defined as a pollutant and reg-ulated by the Ontario Ministry of the En-vironment, is becoming a major problemon our lake. The rock crushing facility islocated about three km away from us.While this seems like a long distance,mainly only trees and water separate itfrom our lake. When the crusher is oper-ating, it sounds like our driveway is beinggraded. When citizens contacted thetownship last year to complain, they weretold municipal noise restrictions only ap-plied from 11 pm to 7am. So there wasnothing to stop the crusher from operatingoutside these hours, even though, it wasreportedly exceeding Ontario MOE noiseguidelines.

In another part of our township, othercottagers face two pronged environmentalassaults. Recently, municipal council ap-proved an application for a dirt bike/mo-tocross park that now hosts daily ridersand sanctioned racing events. Apparently,council approved the track, even thoughan environmental impact study onlylooked at noise levels and other factorsthat related to the race site itself.

It is incredulous to believe that aproper Environmental Assessment woulddetermine that the 118-130 decibels (dB)noise produced by several high perform-ance motorcycles running full throttle,

ter, cottagers lower it into the water on astring, preferably away from shore, andnote the depth at which it disappears; thenslowly raise it, this time noting the level atwhich it returns to view.

Once cottagers pass on their findingsand their water samples, the ministry teststhe water to determine the level of chloro-phyll and algae. The higher the density ofchlorophyll A, the more nutrient-enrichedthe water, and the less hospitable it is forfish and many other creatures in the foodchain. This is a great program as it wouldbe prohibitively expensive for the min-istry itself to take samples from the thou-sands of lakes in the province.

Researchers at the University of Maineestimate that every one-metre decrease inwater clarity may represent a 10- to 15-percent decline in waterfront propertyvalues. For upscale cottage communitiesin Ontario – where prices often start at$500,000 to $1 million – environmentalneglect could cost millions.

Ontario’s next municipal election willtake place this October. This is the idealtime for all of us to question candidatesabout environmental issues and makethem feel accountable to all of us for de-cisions they have made or will be askedto make in the next four years. Otherwise,try selling your dream cottage after a mat-ted carpet of weeds begins to reach outfrom your shoreline, or if ear plugs be-come as necessary as sunscreen.

Voting can really impact your property value

North America has typically adopted termi-nology like “ Guided Wave Radar”, more re-flective of the technology advances, sincethe early TDR days.

Though there was a lot of detail aboutlevel switches (point level) in this article, Ithink it is also worth noting a trend awayfrom this as well. There has been greater uti-lization of transmitters (continuous level)due to their flexibility, and additional infor-mation they provide when used with today’spowerful and cost-effective PLCs andtelemetry systems.

These personal observations are not nec-essarily those of my employer. In the inter-est of full disclosure, I work for a companythat manufactures all of the technologiesmentioned above.Kevin Martyn, Magnetrol Canada

The authors respond: The article is intended to be a brief intro-duction of level technologies used in thewater and wastewater market. All tech-nologies have advantages and disadvan-tages. While I agree that ultrasoniccontinuous transmitters are predominatelyused in W & WW facilities, there aremany applications where RF Admittancewill perform as well, or better, than ultra-sonic.

Guided wave radar transmitters are ex-cellent for many applications, but do offersome disadvantages in respect to RF Ad-mittance. Guided Wave Radar has deadzones at both the top and bottom of thesensor and can be questionable whenmeasuring materials with low dielectricconstants.

I would also like to point out that RFAdmittance is not capacitance. Capaci-tance transmitters measure capacitance.RF Admittance transmitters measure bothcapacitance and resistance, allowing RFAdmittance to reject conductive coatingsthat have caused problems for capacitancetransmitters.

I would also disagree that there is atrend away from using point levelswitches. It is simply best practice to pro-vide a back up level switch for any appli-cation that has hazardous orenvironmentally risky materials. If you re-view standards for level measurements ofthese materials, a back up level switch istypically recommended. Sales of levelswitches continue to grow.

These are personal observations, anddo not necessarily represent the views ofmy employer. William Sholette,AMETEK Drexelbrook

Dear Steve:I am aware thatyour publication,like many othermagazines, re-ceives articlesfrom varioussources, in-cluding equip-ment vendors.There will, ofcourse, be a variety of vendor opin-ions, depending on the products they offer. Imyself have written for Environmental Sci-ence and Engineering Magazine.

Generally, a variety of different perspec-tives would help your readers have a goodunderstanding of the market. However, thearticle titled “Emerging advances in levelmeasurement” in your Summer issue, seemsso out of date, I felt a need to comment.

While it does make a brief mention ofsome modern level technologies, withoutgiving any indication of their use in waste-water treatment, it goes on to promote RFAdmittance (generic term is RF Capaci-tance) as the best currently available tech-nology. Many would agree that thistechnology fell out of favour years ago, dueto its many application sensitivities com-pared to newer technologies.

Vendor objectives aside, (including ourown), I am quite confident you could surveymajor treatment plants in Canada, and findcommon trends that run quite contrary to thesuggestions for contact level measurement,stated in this article. RF level controls wereused in the past, but were generally replacedby ultrasonic level measurements. UnlikeRF devices, these have non contacting levelmeasurement, and don’t have the applica-tion sensitivities that RF level measurementhas.

This change was pioneered by the Cana-dian company Milltronics (now part ofSiemens). To this day, non contact ultrasoniclevel measurement, made by a variety of dif-ferent manufacturers, is the most widelyused level technology in wastewater treat-ment plants. On the emerging side, you havea movement to another type of non contactlevel measurement that is radar (microwave)based. This is not mainstream yet, but I sus-pect most of the major level transmitter sup-pliers would confirm there is movement inthat direction.

If there was a preference to use a con-tacting level technology for some reason,rather than RF with all its limits, GuidedWave (contacting) radar could generally beused, with better results and a similar cost.Early versions of this approach were calledTDR, a term still used in Europe, though

A New Force in Water is Emerging

Water Treatment

Canada to employ large wetland reten-tion ponds to do the work of the clarify-ing tanks and chemicals. There are nochemicals added and no ongoing main-tenance costs. And, once this polishingprocess is complete, most of the natu-rally-treated water simply exfiltratesback to the groundwater table.

In an age when many environmen-tally-friendly innovations tend to lean to-

ward the overly complex, West Elgin’sretention ponds represent a decidedlysimple, almost nostalgic approach. And,in an era when it seems increasingly dif-ficult to please even some of the peoplesome of the time, the community’s latestgreen initiative is receiving positive at-tention from a wide range of stakeholdergroups, including politicians, environ-mentalists, students, ratepayers, water in-dustry experts and the media.

By opting for retention ponds, ratherthan a traditional backwash water treat-ment system, the community was able tosave hundreds of thousands of dollars incapital expenditures. Also, since theponds are maintenance free and require

As you walk along a meander-ing wood chip path in WestElgin, Ontario, you can’t helpbut be impressed by the natu-

ral beauty of the place. An array of nativeplant species of all shapes and sizesadorns the perimeter of two large, inter-connected ponds and the adjacent wet-land. It’s a rural setting, complete withresident wildlife, including ducks, birds,fish, amphibians and small woodlandcreatures.

What is not evident is that this scenicbackdrop serves a dual purpose. In addi-tion to being a place of natural tranquil-ity for wildlife and the community, theseponds are also an integral part of a re-cently completed $16.9 million watertreatment plant.

For decades, most communities inCanada have used a common method toclean the ‘backwash’ or ‘process water’that is cast off as a byproduct of the watertreatment process. This backwash, whichis loaded with suspended solids (silt,algae, etc.) and process chemicals (alum,polymers, chlorine, etc.) is typically storedin large clarifying tanks. It is sometimesfurther treated with chemicals, then thesuspended solids are filtered or allowed tosettle out. Remaining chemicals, such aschlorine, are then removed so the watercan be returned to the original source.

West Elgin is one of the first in

no chemicals, ongoing operational costswill be virtually zero.

The original proposal to use retentionponds, as part of the community’s newwater treatment facility, came from theengineers at Stantec Consulting Ltd. Thecompany has had a significant amount ofexperience incorporating wetlands pondsin wastewater treatment facilities, butthis was the first time it used these ponds

as part of the water treatment process. “Because the West Elgin facility is a

membrane facility, and there is an ex-tremely low amount of chemicals usedwith these types of plants,” said ElvioZaghi, of Stantec, “we had the wetlandspond alternative available to us. So weproposed this alternative to the commu-nity. Once the key players realized whatthey would be able to achieve with thisapproach, everyone was extremely sup-portive of the idea of incorporating theseponds as part of the new facility.”

Mindful of the larger significancethese ponds would hold for West Elgin,Stantec made a special point of engagingthe community in every phase of the

project. One of the first organizations in-volved was the West Elgin Nature Club,a local group founded in 1946. It playedan active role in helping design the land-scaping plan for the ponds, the layout ofthe wetland, where the paths should belocated, etc.

The group also helped by recom-mending (and helping to plant) many ofthe native plant species currently grow-ing in and around the ponds. A numberof students from the local high-schoolhelped with the planting process.

Before construction, Stantec under-took extensive, year-long hydrogeologicaltesting in the area to observe water move-ment patterns. The new water treatmentplant was being built on an entirely newsite and the property the municipality pur-chased contained a provincially signifi-cant wetland. Whatever was to be built onthe site could not negatively impact thewetland, or the natural setting of the area.

Incorporating retention ponds that ex-filtrated the plant process water actuallyhelped maintain the high groundwaterlevels in the wetland area, ensuring thatthe natural wetland nearby will last for

generations to come.Key features of the project include:

• The water treatment and retentionponds have been online since April 2009.

• System was designed for the 20 yeardaily flow of 12,160 m3/d.• 90% of the cost of the new water treat-ment facility was paid for by the Canada-Ontario Municipal Rural InfrastructureFund, a partnership between the Govern-ment of Canada, the Government ofOntario, and the Association of Munici-palities of Ontario.• Wetland retention ponds were built to

ice, promote customer satisfaction and,ultimately, reduce costs to the utility.

Research identified some high per-forming water utility call centres thatcurrently demonstrate Best Practices inareas such as automation (AMR, self-service, and electronic bill payment),outsourcing (cloud computing), person-nel training and management, and mak-ing use of information gained fromcustomer interactions.

Some utilities provide call centre

Fourteen utilities from the UnitedStates and Canada participatedin a Water Research Foundationproject to develop and operate

more efficient, comprehensive, and cost-effective customer contact centres.

Specific objectives were to identifyprocesses and technologies to improveperformance, define techniques to in-crease customer satisfaction, and identifycharacteristics that would make call cen-tre positions a “job of choice”.

The following areas were studied:• Out-of-industry trends in contact

centres (literature review).• The current state of water utility

contact centres (structured interviews).• Future trends and needs (utility

manager interviews).• Current best practices (case studies).

Currently, the business model fortoday’s water utility customer call centreis typically structured around a reactive,problem resolution mode, i.e., resolvingbilling and other complaints, answeringquestions, and handling field-related is-sues.

With the enormous advances in cus-tomer contact centre technologies andheightened awareness of the importanceof customer service and satisfaction,water utilities can significantly expandand optimize the centre into a utility-wide resource to raise the levels of serv-

services to nearby utilities, taking ad-vantage of economies of scale to acquiretechnology. Applications and recommendations

The final report contains both a writ-ten report and a toolkit (enclosed on aCD) for water utilities to use in planningfor and optimizing their customer con-tact centre. Presented in a concise for-mat, the toolkit includes an outline ofthe current state of these centres, trendsin customer contact centres, characteris-tics of the water utility customer contactcentre of the future, case studies, andbest practices and processes for achiev-ing high levels of customer satisfaction.

The optimization toolkit consists offour components: self-assessment tool,benchmarking tool, improvement plantool, and a resource guide. It containsrecommendations that are size differen-tiated, so a utility will see different rec-ommendations depending on whether itis a small, medium, or large utility.

This toolkit was tested at seven utili-ties, ranging in size (population served)from 49,000 to 1.2 million.

When the discharge point ofa three-mile force mainwas changed from a pumpstation to the treatment

plant in Suffolk County, New York, theodours got so bad even the operators com-plained.

“It was awful,” says Ron Warren, Di-rector of Operations and Maintenance atthe county’s 2.6 million gallon a daySewer District #11 facility in Coram onLong Island. “It was not just your normalhydrogen sulfide odour, but we had a lotof mercaptans, as well. We had to switchthe force main back to its original dis-charge point until we could find a solu-tion.”

Warren explains that the original de-cision to move the force main dischargepoint was made for cost-saving reasons.“We needed to reduce the head pressure(of the force main) on that pump station,plus we had a lift there of some 12 feet.It just made sense to take the main di-rectly to the plant and avoid that lift.”

In doing so, however, odours became

more concentrated and simply over-whelmed existing odour control devices.“In the old arrangement the odours hadbeen somewhat diluted, but when weconnected the main to the plant, our ex-isting odour system simply couldn’t pullthe air fast enough,” Warren explains.

Pumping the discharge point back toits original location wasn’t an efficientpermanent solution either because it wasusing an additional 10 horsepower.

“The odours were too concentratedfor the existing chemical scrubber, andwe had tried carbon,” says Warren, “but

O-MEGA® systems from Vapex Inc.,Florida, utilize air, water and power togenerate a hydroxyl ion fog that is in-jected into the odorous space through aspecial atomizing nozzle and reacts withthe odorous compounds. Unlike a scrub-ber system, there is no need to withdrawodorous air from the structure and pass itthrough a separate odour-control scrub-bing process, because the reacted mistsimply condenses back into the waterstream. No hazardous chemicals are pur-chased, handled or stored.

Lift stations and wet wells are excel-lent applications because they act as thereaction chambers. The hydroxyl ion fogcan also reduce hydrogen sulfide corro-sion within the structure, break downgrease, and kill biofilm.

The fogging systems are available ina variety of sizes, with a range of nozzleoutput rates and coverage areas.

Metro Vancouver’s drinkingwater comes from threewatersheds:Seymour,Capilano and Coquitlam.

The Seymour and Capilano sources sup-ply 70% of the region’s demand fordrinking water.

With new quality standards now inplace, chlorine, which was used at theSeymour and Capilano reservoir, couldno longer effectively cope with the highlevel of turbidity occurring on rainydays, while achieving Metro Vancou-ver’s goal of minimizing chemical resid-uals in drinking water. An alternativewas required.

Energy Conservation

Standardizing processes is about un-derstanding the best practices, capturingthose practices and implementing themacross the plant(s); understanding whichenergy data to collect, where to collectfrom, how frequently to collect the data,and how to use the data to make effectivedecisions. This process will enable com-panies to equip employees with the rightenergy information at the right time totake corrective and preventive actions.

2. Organization. One of the commonchallenges is the level of awarenessamong employees about managing en-ergy throughout the plants. Another isthat the employees on the plant floor donot have a lot of influence and controlwhen it comes to making energy man-agement decisions. And, often, a lack ofcollaboration between corporate engi-neering and plant engineering groupsmakes the process very slow.

Establishing corporate teams to ensurethe success of an energy managementprogram is important, but companiesneed to ensure that the strategies estab-lished in the boardrooms are imple-mented efficiently on the plant floor.Establishing roles and responsibilitiesacross the functional teams will ensurethat the corporate goals are well commu-nicated to employees.

While driving accountability for en-

The volatile price of energy hasput increased pressure onexecutives in energy-intensiveindustries. It is now more im-

portant than ever to understand a plant’sneeds and to cut out wasteful consump-tion wherever possible so that companiescan improve the predictability of energyusage.

The main pressure driving companiesto focus on energy management is theneed to reduce costs in operations. Plantmanagers often underestimate the op-portunity to reduce costs through an ef-fective energy management strategy. Thisis especially critical in energy-intensiveplants where energy can account for asmuch as 25% of total operating costs. Insuch a scenario, the ability to cut even asmall percentage of total energy con-sumption can result in significant savingsfor the organization.

Other market pressures are the needto maintain system reliability and avoidoutages, and the desire to be a leader insustainability.

The top strategies for energy manage-ment are:• Redesigning/optimizing processes to

be energy-efficient.• Including energy management in

company initiatives.• Creating or improving collaboration

across functional groups.• Incorporating energy management

when designing new processes and production changes.Energy management is not just about

tracking consumption through utility billsbut is also about how effective companiesare in considering energy in operationaldecision-making. Including energy man-agement in enterprise-wide initiatives en-sures that all employees have “skin in thegame” when it comes to energy manage-ment.

Best practices for energy management

1. Process. One of the best practicesfor companies is to put in place an effi-cient process to enable the success oftheir energy management initiatives. Es-tablish short-term and long-term goals forplants/facilities or remote site locations.

ergy consumption is critical, rewardingthe plants/departments which achievetheir goals fosters an energy-aware cul-ture across the organization.

3. Knowledge Management. Thereare two ways to manage knowledgethroughout the enterprise: manual datacollection (very cumbersome), and auto-matic collection of energy data which arethen stored in a central location. Ensur-ing employees have access to both real-time and historical energy data helps todevelop an understanding of the trendsin energy usage in a plant.

Many large organizations are turningto Historian systems to manage historicaldata. A Process Data Historian system isa specialized database that allows forlarge amounts of data to be archived andreadily retrieved in far less time than atraditional database. This enables seam-less access to both real-time data and his-torical trends of processes and energymanagement, leading to more informeddecisions and better energy utilization.These products are designed with anopen-architecture, allowing them to beeasily combined out of the box, allowinga faster time-to-solution.

While having energy informationis critical, the next step is to utilize theinformation to optimize operationalprocesses (maintenance, production, etc.)

Driving value with energy management in waterand wastewater environments

Energy Data + Production Context = Information.

By Ivan Romanow


Energy Conservation to reduce energy consumption.

Energy data and asset condition datacan be used together to schedule mainte-nance activities.

For example, if there is a motor orpump that is utilizing more energy than itis rated for, this can be flagged for ascheduled maintenance.

4. Performance Management. Effec-tive measuring of energy managementperformance is essential. This enablesplants to benchmark themselves inter-nally across functional groups or sisterplants, as well as externally against in-dustry standards. This allows manage-ment to continuously monitor andmeasure the success of the energy man-agement programs and to make futuredecisions on using the program in otherareas or plants within the enterprise.

5. Technology. Most of the energy inall plants is consumed by the equipmentin the plants. Investing in energy effi-cient hardware such as variable fre-quency drives (VFDs) and energyefficient lighting is extremely helpful inreducing energy consumption. For ex-ample, VFDs can be used to save energyon rotating equipment such as fans,pumps and conveyors, by controlling thespeed of a motor through adjusting thepower supplied to the equipment. Thishas been identified as a major source ofenergy waste.

Consultants provide value throughplant audits, helping executives to un-derstand gaps in energy managementprocesses, and they also provide somecritical recommendations on the steps re-quired to make a plant more energy-ef-ficient.

Energy management tools help com-panies to collect energy data automati-cally, providing real-time insight into theenergy processes that aid in operationaldecision-making. They allow companiesto collect critical energy informationsuch as energy consumption, energycosts, and energy efficiency, and enablethem to drill down to data per plant or re-mote locations. This information is crit-ical in making decisions on efficientenergy usage.

Statistical process control software al-lows companies to establish limits, andalerts management when the processesare out of control limits. Investing in an-alytics, dashboards, and alert manage-

ment, provides the right energy data tothe right person at the right time to en-able decision-making.

Combining energy management withasset management enables maintenanceto include energy consumption datawhile scheduling their activities. Simi-larly, the integration of energy consump-tion data with Advanced Process Controlallows plant operators to include criticalinformation related to energy usage andcost in the optimization process, alongwith other variables on the plant floor, to

achieve the optimal balance of output,quality, and energy efficiency.

Dashboards and analytical solutionswill enable executives to understand thereal value from a huge amount of energydata collected, and to present the data tothe appropriate employees for efficientdecision-making.

Disinfection

ously checked for crystallization withinthe wetted parts. These flexible parts cansplit and cause contamination of the en-vironment and danger to personnel.

Pumps are the least expensive methodof feeding NaOCl, unless the cost con-siderations of personnel safety, mainte-nance, clean-up, repair and possible spillalleviation are taken into consideration.

Vacuum Feed SystemsVacuum dosing is similar to the

process used to feed gaseous chlorine,ammonia and sulfur dioxide, and recentadvances have improved on that technol-ogy. In a vacuum feed system, a properlysized and placed ejector or inductionmixer produces the required vacuum todraw the NaOCl through the dosing sys-tem. The caustic flow is then metered,using a V-notch rate valve controlled byan electronic flow sensor, into the feed-water. There is never high pressure in thecaustic lines, nor is there a requirementfor a vacuum regulator in the feed line.

Advantages of a vacuum feed systeminclude:• Increased operator safety compared

Organizations and associationshave regulated the use andstorage of chlorine to thepoint that alternatives have

been explored for water disinfection forthe past 20+ years. One result is the useof liquid sodium hypochlorite (NaOCl).

Although NaOCl requires more stor-age space than gaseous chlorine, it canbe handled more easily and it createsfewer maintenance problems than otherdisinfectants. It also provides residualdisinfection and lower capital costs.

Commercial grade NaOCl is corro-sive, relatively unstable, and very caus-tic. Personnel who handle NaOCl needto take the same precautions as theywould for any caustic material. NaOClemits oxygen when it degrades, but itwill react to most acidic materials,which will combine to release chlorinegas. In case of an NaOCl spill, the ma-terial can be easily diluted with waterand will naturally degrade to oxygen andsalt, usually within 72 hours.

The Delivery SystemCurrently, there are two techniques

used to feed NaOCl. Traditionally, me-tering pumps of either the diaphragm orperistaltic type have been used, but therehas been a growing interest in the lastseveral years in vacuum dosing.

PumpsPumps have been the usual method of

dosing NaOCl, but experience has iden-tified a number of constraints to thistechnology: 1. Pumping a liquid requires that the linesthroughout the system are pressurized, sopumping NaOCl can be dangerous to per-sonnel in the case of a line break.2. Diaphragm pumps are prone to gasi-fication, which will form a vapor lock,and eventually cause crystallization,which will jam the operating mechanismin the pump’s wet end.3. Suction piping should be kept short inorder to guard against gasification. Thisrequires that NaOCl solution tanks arein the same enclosed area as the pumpand inside the plant.4. All dosing pumps, either diaphragmor peristaltic in design, must be continu-

to pressure systems.• A wide range of flow – 3 to 20,000

GPD.• High accuracy – +/-2% of actual

feed.• 100:1 turndown ratio.• No air binding possible.• Caustic storage and ejectors can be

located outside of the disinfection building.

• No pressurized caustic lines.• Few moving parts, thus less

maintenance and down time.One inherent disadvantage of the vac-

uum system is the potential for scaling atthe contact point between the chemicaland the motive water in the injector. Thiscan be avoided by accounting for thescaling potential during the design phase.Water softeners can be installed ahead ofthe injector to completely eliminate thisproblem, or various automatic injectorswitchover schemes can be included inthe design of the vacuum feed system.

Water Treatment

By selecting one network for the elec-trical, control, and instrumentation sys-tems, engineers could quickly focus onthe design portion of the project and spec-ify all the necessary components to en-sure long-term reliability of the system.

Grant Whitehill, a Delpro sales repre-sentative, worked with Siemens engi-neers, the systems integrator Turn-Key

Greater Vernon Water, in theRegional District of NorthOkanagan, British Columbia,supplies drinking water to

agricultural and non-agricultural cus-tomers in the Greater Vernon area. In2005, AEKWL, a consortium of Associ-ated Engineering and Kerr Wood Leidal,was hired as consultants to work withGreater Vernon Water to begin construct-ing a new water treatment plant at the ex-isting reservoir and pump station site.

Completed in June 2006, the newplant supplies 40 million litres of drink-ing water per day to 35,000 customers inthe Greater Vernon area.

The plant intakes water from KalmalkaLake, using four pumps. This raw water isthen passed through UV reactors and isfurther disinfected with sodium hypochlo-rite, which is generated on site. Thedisinfected water is discharged into thepressure grid of the city, and into a 14-mil-lion-litre-capacity reservoir.

In designing the new treatment plant,engineers strived for cost-effectivenessand efficiency throughout the project.This included a streamlined design/buildphase, followed by safe operation. An-other requirement was to work with theleast number of suppliers possible with-out sacrificing quality, durability or reli-ability. The project required level, flow,and pressure instrumentation.

Controls, and project engineers to pro-vide a Totally Integrated Automation so-lution from Siemens. From networkcables to instrumentation, engineerswere able to work with one company for95% of the project’s instrumentationneeds, satisfying engineering require-ments through all three phases of theproject.

The Profibus network was the net-work of choice for several reasons. It canhandle both instrumentation and electri-cal control on one network; it is proven,with over 30 million nodes worldwide; itworks well in multi-vendor applications;all instruments can be configured overthe bus using one configuration package,SIMATIC PDM; and it allows flexibilitybetween products and keeps wiring andinstallation costs low.

Engineers were able to work with onesupplier for all level, pressure, and flowinstrument requirements, including: 1. Ultrasonic transmitters (SITRANSProbe LU) continuously measure thelevel of sodium hypochlorite. Three unitsare installed on three separate tanks. TheSITRANS Probe LU is a two-wire, loop-powered ultrasonic transmitter. It has acompact design, with sensor and elec-tronics in one enclosure, and is easy toinstall. The swivel head aligns the con-duit for easy wiring and adjusts for opti-mal visibility.

It offers a high signal-to-noise ratioand patented Sonic Intelligence signalprocessing. The narrow beam angle al-lows operators to position the sensor ex-actly where it is needed. It is easy to setup on site with as few as two parameters.In this application, it was wired directlyinto the Profibus network for centralizedcommissioning and control from thecontrol room. A built-in alpha-numericdisplay is visible through the transparentlid for on-site confirmation of the meas-urements.2.

Differential pressure transmitters(SITRANS DSIII) monitor pump dis-charge pressure, grid pressure, the levelof brine tanks, and the level of the fin-ished water reservoir. This transmitterhas advanced diagnostics features and anaccuracy of +/- 0.075% of reading. It canbe programmed locally, using three

pushbuttons, without the need for hand-held devices or a laptop. The transmittershave seven basic measuring cells cover-ing a complete range of applications,thus reducing the number of spares re-quired.

Benefits of using one supplierBy choosing Siemens instrumenta-

tion for this project, Greater VernonWater only needed to deal with one sup-

plier of electrical, instrumentation, con-trol, and SCADA systems, includingWINCC, Siemens PLC, MCC andSmartdrives. This made implementationof integrated plant operations easy andprovided centralized visualization andcontrol.

It is easy to troubleshoot any of theProfibus devices with the help ofSiemens PDM (Process Device Man-ager) software. The devices can be ad-justed, calibrated and diagnosed from acentral location, which reduces physicalvisits to the equipment, thus saving timeand improving operator safety.

In addition to providing the instru-mentation, Siemens was the only vendorthat could connect the UV system HMIto the central SCADA system in the con-trol room on Ethernet. This allows theoperator to visualize and intervene in theUV operations from the control room in-stead of going to the UV reactors, savingrunning time and maintenance costs.

ting fluid in most of its machining oper-ations. Since there is only one type ofcutting fluid being used at this particularfacility, there is no concern that the re-cycler would experience cross-contami-nation with two or more fluid types.Typical cutting fluid recyclers are stand-alone machines that can be positioned inan unused corner of a facility or anyother accessible location.

After reviewing each process in thefacility, it was calculated that the manu-facturer was spending approximately$135,000 a year on new make-up fluidand off-site disposal of cutting fluids.The manufacturer decided to implementa cutting fluid recycler process. The costfor engineering services, purchase of acutting fluid recycler, and installationand training, was in the order of $60,000.

After four months of operation, it was

Cutting fluids are primarilyused in manufacturing facili-ties where milling or CNC(computer numerical con-

trolled) machines are present. The mainpurpose of a cutting fluid is to cool andextend the lifespan of tooling used in themachining process.

Most cutting fluids have an almost in-finite life cycle. The main reason theyare disposed of is because they becometainted with unwanted tramp oils andmetal cuttings. which provides an envi-ronment for bacteria to grow in. Whenbacteria are present in a cutting fluid itbecomes rancid and unusable from ahealth and safety perspective, and canalso become unacceptable for other rea-sons, such as concentration, pH and al-kalinity.

Recycling allows for the recondition-ing of cutting fluids to restore them totheir original condition.

Recyclers use various methods to re-store cutting fluids. Tramp oils areskimmed from the surface, magneticseparators and paper filter media areused to extract particulates, and an oilcoalescer is used to ensure tramp oilsthat were not removed by the skimmerare removed from the cutting fluid. Atthis point, the concentration of the fluidmust be adjusted, either to raise or lowerthe current concentration in the recycler.Most cutting fluids are anti-bacterial by

nature; adding new make-up fluid helpsensure that any remaining bacteria areeliminated.

Manufacturers of cutting fluid recy-clers typically report that they can savean operation up to 90% on new cuttingfluid make-up and disposal of spent cut-ting fluid.

Case study – auto partsAn auto parts manufacturer in the Ni-

agara Region is using a soluble oil cut-

determined by the manufacturer’s lubri-cation and oil operator that the cuttingfluid recycler was achieving real-worldefficiencies close to 75%. With powerconsumption, filter paper replacement,and an annual diaphragm pump change,this efficiency drops, albeit marginally.

With an overall estimated 70% effi-ciency, the manufacturer is expected tosave $95,000 a year on cutting fluid ex-penses. Industrial operations typicallylook for a buy-back on equipment of twoto three years, but the cutting fluid recy-cler in this case was expected to pay foritself in less than eight months.

Cutting fluid recycling is not onlyfeasible and environmentally friendly,but it can also help companies cut costssignificantly. Other than normal mainte-nance and an annual expected pump re-placement, a cutting fluid recycler’stypical lifespan can easily reach 15 to 20years. In this case, it equates to savingsin the order of $1.4 to $1.9 million.

In June 2006, Groupe C. Laganièrewas contacted by the CEO of a pri-vate greenhouse flower farm nearMontréal, asking for emergency

containment solutions in the aftermathof a significant oil spill on the produc-tion site.

A team of environmental profession-als was immediately deployed, and in-vestigation of the site revealed that thesource of the contamination was a dam-aged piping system linking an old tankto an out-of-use indoor furnace.

It was presumed that the 5,000-gal-lon-capacity outdoor tank was full of fueloil prior to the spill. In the past, the tankhad been used to heat the greenhouses,but it had been abandoned while still fullabout 15 years earlier, when the previousmanagement had installed a new, natu-ral-gas-powered heating system.

two phases of environmental assessmentsand remediation work. Phase I lastedfrom June to October 2006, while PhaseII started in May 2007 and was success-fully completed by December 2008.

As further investigations indicatedthat the piping had been damaged delib-erately, the farm’s insurance companywas also called in. During the 2-1/2years of coordination and pollutionmonitoring and removal at the site, morethan 20 environmental professionals,health and safety specialists, and repre-sentatives of various parties, includingthe insurance company, farm adminis-tration, the Québec environment min-istry (MDDEP), Environment Canada,city clerks, and neighbouring landown-ers, provided expertise and their re-quirements, resulting in an efficient andsustainable clean-up of the property.

Managing this case was very com-plex, due to the large amount of con-tamination, the required compliancewith municipal, provincial and federallaws and regulations, and the agricul-tural nature of the property.

The property covers an area of about

20,375 m², and the greenhouses occupy65% of that space. Sedimentation in thearea is composed of a sand backfill(0.15m thick), lying on an argillaceoussilt more than 5 m deep.

The farmland is relatively flat, and itselevation is 35 m. Depending on the sea-son, the groundwater level is between 0.5and 1.4 m deep. Because of the topogra-

phy of the site, underground run-offwater flows in a 600-m-long drainageditch, located on the southwest side ofthe property. Surface waters in this ditchare then discharged into a Hydro-Québeceasement ditch, located another 350 mfurther in the same direction. This ditchfinally flows over a distance of 395 m

process. If the farm had not reactedquickly, the contamination would havecontinued to spread at a very fast rate.

The emergency environmental opera-tions team was able to contain further mi-gration of the contaminants in the surfacewaters by strategically digging a 700-m-long ditch along the natural migration linefrom the leak. PAHs and PH C10-C50 ab-sorbent cushions were then aligned in it.These were able to absorb about 50% ofthe surface pollutants that were present inthe ditch when emergency operationsstarted, then up to 95% of the new waterflowing in. (See photo 3)

Specialists also proceeded with dis-mantling the tank and its piping systemand removed contaminated soils aroundit. A total of 274 tons of contaminatedsoils, mostly from around the tank andthe greenhouses, was removed and safelydisposed at a soil treatment facility inQuébec. By the end of June, a total of7,953 litres of oily water had beenpumped out of the drainage ditch with avacuum truck and sent to a treatmentcentre in Montréal.

The remaining fuel oil, floating onthe surface, was also taken away withthe absorbent materials, and by August2006, 10 barrels of contaminated ab-sorbent cushions were sent to anothertreatment and recycling facility. Evenafter these emergency removals, how-ever, analytical results revealed that theremaining soil and water were definitelycontaminated beyond the level allowedby the MDDEP for an agricultural prop-erty.Therefore, a fully integrated decon-tamination solution was required.

Fieldwork was then suspended forthe winter, which allowed for full prepa-ration for Phase II in the spring. A multi-aspect and sustainable environmentalmitigation/remediation plan had to bedeveloped, and reviewed and approvedby the Québec MDDEP and the city au-thorities before the start of Phase II.

Environmental remediation - Phase II

By the spring of 2007, the completeremediation plan had been establishedand approved by the MDDEP. In Québec,it is mandatory to submit remediationplans to the government when an author-ization certificate is requested. In thiscase, such a certificate was required, anddelivered, to allow on-site water treat-

into the municipal sewer system.The calibrated watershed of the

drainage ditch has an area of 109,675 m²,and the estimated discharge rate betweenApril and June is 115 litres/minute.Added to this is the discharge rate of thewatering/drainage system for the irriga-tion of the greenhouses, which is around62 litres/minute.Environmental remediation - Phase I

It took about three days for the ad-ministration and employees of the farmto see and smell traces of contaminationaround and inside the main green-houses, since the incident happened on aweekend. By the time they realized whatwas happening, the primary affectedarea was a 400-m line following the nat-ural waterway on the property.

When Groupe C. Laganière’s emer-gency response team arrived, the con-taminants had reached a drain used tocollect residual waters for irrigation in-side the greenhouses (see photo 2). Asthis drain was connected to a ditch, itwas only a matter of a few hours beforean additional surface area of 450 m2 wascontaminated as well.

The immediate intervention plan, ap-proved by the MDDEP, called for re-trieval of the red-coloured fuel oil fromthe excavations and drainage ditch. Theabnormally rainy month of June 2006,combined with the high level of waterused by the farm for its commercial ac-tivities, had helped to spread the contam-ination and complicated the remediation

ment (see photo 4). The plan called for asix-step approach to get the farm backinto production.

The goal of Phase II was to reach adegree of contamination concentrationequal to or better than criterion A, whichapplies to agricultural properties. Resid-ual soils must be analyzed to determinewhether all the contaminated soils havebeen effectively removed from the prop-erty. Surface waters must be treated untiltheir level of contamination meets lev-els allowed by the city and province fordischarge to the public sewer system. Fi-nally, all work must be coordinated tomeet safety and health requirements foreveryone admitted into the area.

The components of the six-part planwere:1. Construction of a containmentpond. Remediation of the site requiredthat the new drainage ditch be dried outcompletely, in order to collect the con-taminated soil and mud at the bottom.To do so, Groupe C. Laganiere had tobuild two dikes, upstream and down-stream, on the existing natural ditch, tocontain water and prevent the ditch frombeing constantly filled with new water,which would immediately be contami-nated. The residual surface water in thecontainment ditch (400 m long) waspumped into the treatment unit andtreated until clear of contamination.

New water (rain and residual irrigationwater) naturally flowing into the ditch wascollected through a 2-in. pipe at the up-

stream dike. It was also directed into thetreatment unit for pre-emptive treatment,safely confined while analyzed in an ac-credited laboratory, then dischargeddownstream, upon confirmation that thecontamination level was meeting the cityand MDDEP criteria, as specified by thecertificate of authorization.

Water collected upstream and dis-charged downstream without penetratinginto the ditch always presented admissi-ble (extremely low) levels of contamina-tion and did not require additionaltreatment cycles. It joined the multiple-treatment decontaminated waters at thedownstream dike and continued its natu-ral flow toward the municipal sewersystem.2. Management and purification ofsurface water in the pond. Water gath-ered in the containment pond waspumped out with a submersible 12gal/min pump and treated with an Ultra-Sorber™ CARB-LP-170 activated char-coal filtration system that discharged intoa sanitized container for PAHs, MAHs,BTEX and PH C10-C50 chemical analy-sis. The system has proved highly effi-cient, and after thousands of cycles withthis on-site treatment device, the water fi-nally met the city and MDDEP criteria fordischarge into the city’s sewer system.

The water that kept flowing into thepond during the soil remediation step wastreated. The containment pond temporar-ily dried out, but it then kept being filledagain with wastewater from irrigation ofthe greenhouses. This water was treatedthe same way throughout the process.3. Contaminated soils remediation.The remediation technique chosen at thissite was by a vacuum truck, but, by De-cember, the weather got far colder thanaverage for the month and it was re-placed by a hydraulic excavator. (seephoto 5)

A total of 570 tons of contaminatedsoil was excavated from the entire lengthof the new ditch, of which 198 tons pre-sented a contamination level within theB-C criteria (MDDEP), while the re-maining 372 tons were contaminated be-yond the C level.

ries about dynamic systems undergoingtransitions at a tipping point, particularlya phenomenon known as “critical slow-ing down.(CSD)”

“This is the first experimental demon-stration of critical slowing down in a bio-logical system,” said Drake. He explainedthat critical slowing down is a term usedto describe a pattern in data that has pre-viously been observed in physics andEarth sciences, but until now has beenonly a theoretical possibility in biology. Itdescribes the decreasing rate of recoveryfrom small disturbances to a system as itapproaches a tipping point. When a sys-tem is close to a tipping point, it can takea long time to recover from even a verysmall disturbance. This also is the firsttime the theory has been applied to ex-tinction.

The experiment featured populationsof water fleas that were assigned to eitherdeteriorating environments (in this case,declining levels of food) or stable envi-ronments (the control group). The exper-iment lasted for 416 days, when the last

thing about it? Findings from a study by associate

professor John M. Drake, at the Univer-sity of Georgia , and Assistant ProfessorBlaine D. Griffen, at the University ofSouth Carolina, may eventually lead tosuch an outcome. Their study also hasimplications for understanding drastic,even catastrophic, changes in manyother kinds of complex systems, fromthe human brain to entire ecosystems.

The paper, “Early warning signals ofextinction in deteriorating environ-ments,” describes a study of the fluctua-tions in experimental populations ofwater fleas (Daphnia magna) undergo-ing environmental stress, until theyreach a tipping point beyond which theydo not remain viable. The study isunique in its careful comparison of thesestressed populations with other, healthypopulations, in the context of new theo-

Dependingupon the amount of food they received,populations in the deteriorating environ-ment group reached the population via-bility tipping point after approximately300 days. Populations in the control groupnever reached it; those populations per-sisted.

The researchers next looked at a va-riety of statistical indicators, early warn-ing signals that could detect the onset ofCSD and thereby predict the approachto a tipping point. They compared the in-dicators with the timing of the decreasein food and with the achievement of thetipping point, mathematically referred toas a “transcritical bifurcation.” Theyfound that each of the indicators showedevidence of the approaching tippingpoint well before it was reached.

pollution issues. Years of scientific re-search, in co-operation with several uni-versities and other innovative Canadianenterprises, preceded the developmentand launch of this product.

Air quality in major Canadiancities continues to improve,but the negative health im-pacts of air pollution remain

a serious issue. Urban development andtransportation planners, as well as mu-nicipal health officers, realize that moreis needed than just monitoring air pollu-tant concentration levels at a few criticalsites. For a full assessment of the healthimpacts, detailed information is requiredabout the levels of the air pollution overpopulated areas and public facilities suchas parks, schoolyards and sports fields.

Installation, maintenance and opera-tional costs of extended air qualitymonitoring networks are considerable.Fortunately, space technologies can offerinnovative yet practical and cost-effectivesolutions. In the past decade, new earthobservation satellites were designed andlaunched to provide daily maps of globaland local distributions of major air pollu-tants. New methodologies are being de-veloped to exploit this rich source ofenvironmental information.

In North America, A-MAPS Environ-mental Inc., based in Ottawa, has spe-cialised in applications of environmentalsatellite remote sensing. The companyhas developed a new approach to providemunicipal planning and health officeswith essential information on urban air

Using satellite data to monitor the quality of urban air By Daniel Spitzer, Gray O'Byrne, Natty Urquizo and Bojan Bojkov


Air Pollution MonitoringEuropean Space Agency. Processing theatmospheric remote sensing data re-quires detailed understanding of atmos-pheric physics and chemistry.

Using the satellite observation datadoes not mean that traditional air qualitymonitoring networks will become obso-lete. On the contrary, creating reliable airpollutant distribution maps requires ad-justment of the satellite data by using theresults of air pollutant concentrationmeasurements at several ground levelsites. Subsequent interpretation of thedata is based on complex geospatial andemission dispersion models.

These efforts result in detailed, hourlydistribution of digital maps of harmfulair pollutants such as nitrogen dioxide,ozone and small particulates. The airquality mapping products in GIS formatsare presented through interactive graph-ical user interfaces or web applications.Development of such web applicationsfor the National Capital Region (Canada)was funded by GeoConnections/NaturalResources Canada.

To disclose the vast amount of infor-mation concealed in the air pollutiondatabases, geospatial analysis of the datais needed, so the company developed agraphical user interface called MAGIQA(Map Analysis Graphical Interface forQuality of Air) that enables analyses andeasy presentations of air pollution data.The software includes conversion of anyenvironmental records into GIS mappingformats. Specific time periods and areascan be selected on screen within themapped region for processing and analy-sis. Moreover, series of imagery can beviewed as an animation.

The analyses include standard statis-tical and custom-designed functions suchas averaging, maximum, minimum, stan-dard deviation, percentiles, and criticalpollutant level exceedancies. This infor-mation is presented in mapping and othergraphical formats, which can be dis-played, printed and saved.

Assessing air pollution health impacts

One of the key concerns of municipalplanners is evaluating the consequencesof different city development and landuse scenarios. Particularly important isconsidering the implications for publichealth. Another product developed by A-MAPS Environmental, in co-operationwith Risk Sciences International, is a

customized interactive graphical inter-face that enables direct assessments ofthe impacts of urban road traffic emis-sions on population health.

Different traffic control scenarios canbe tested by modifying traffic volumesand speeds on selected roads or in entireneighbourhoods. The consequences ofsuch changes in terms of air pollution andhealth impacts can then be reviewed andevaluated in mapping and tabular formats.

Development of the new populationhealth assessment tool was funded by theEuropean Space Agency’s Data User El-ement program (www.esa.int/due). Anexample of an application of the inter-face, showing the consequences of traf-fic rerouting from a busy highwaysection to a residential area in Ottawa, isshown in Figure 1.

Since 2007, the City of Ottawa has in-troduced a regional air quality mappingsystem based on satellite remote sensing,ground-level air quality measurementsand geospatial modelling. This uniquesystem comprises an interactive air qual-ity mapping website and interfaces fordata analysis and health impacts assess-ments. Concentration levels of NO2, NO,

O3, PM2.5 and CO are measured hourlyat several locations by monitoring instru-ments, and then recorded and processedfor further mapping of the air pollutantconcentration distributions over the entireNational Capital Region.

Along with local measurements, themapping process is supported by datafrom the National Air Pollution Surveil-lance system and from the Aura/OMI at-mospheric satellite sensor. All collectedand processed data are then used as in-puts into a geospatial model, allowing airpollutant distribution maps to be gener-ated and presented hourly in GIS formats.

To expand the air quality informationsystem, the City’s Community Sustain-ability department will include a newspecific module that will provide de-tailed information about air pollution onbusy streets.

Drinking Water

However, the text supporting those rec-ommendations also included a number ofadditional suggestions and sound guid-ance that would address several unre-solved questions about drinking water:1. Who will pay for source protectionimplementation? So far, the provincehas largely paid the costs involved in de-veloping source protection plans. How-

It has been 10 years since the Walk-erton tainted-water tragedy killedat least seven people, sickenedabout 2,500 others and single-

handedly curtailed the provincial gov-ernment’s “self-regulation” philosophy.

The report of the Walkerton Com-mission laid out a detailed blueprint forrebuilding public confidence in thesafety of the province’s drinking watersupplies. Many of Justice O’Connor’srecommendations in that report havebeen fully implemented.

There are now mandatory drinkingwater standards; a source-water protec-tion planning process; better training andcertification of operators; licensing of allmunicipal residential drinking water sys-tems; regular review and revision ofdrinking water standards; licensing, ac-creditation and inspection of testinglabs; more vigilant enforcement; andgreater public transparency through theannual reports issued by both the minis-ter of the environment and the chiefdrinking water inspector.

The province has announced that allof Justice O’Connor’s 121 formal rec-ommendations have been implemented,or at least the enabling legislation neededto implement them has been passed.

ever, there is no commitment to covercosts to implement those plans.

The Walkerton Report recommendedthat the provincial government ensuredthat sufficient funds were available tocomplete the planning and adoption ofsource protection plans. Justice O’Con-nor did not recommend that these costscome exclusively from provincial cof-fers, and he recognized that componentsmight have to come from municipalwater rates charged to water users andeffluent dischargers. Ontario has yet todevelop a comprehensive plan to ensurethe necessary funds are available.2. When will full-cost accounting be im-plemented? Justice O’Connor recog-nized the linkage between “full-costaccounting and recovery” and safe drink-ing water, and the importance of financialsustainability to the health of all Ontari-ans.

Coincident with the Inquiry, theprovince passed the Sustainable Waterand Sewage Systems Act, which wouldrequire municipalities to institute full-cost accounting and recovery for waterand wastewater services. Aware of thislegislation, Justice O’Connor had ex-pected that implementing regulationswould follow. Even though the Act was

passed in 2002, the province has not passed the implementingregulations.

This is one of the missing pieces in the clean water puzzle.Full-cost accounting and cost recovery plans are important tofinancing source protection and infrastructure renewal.

The new Water Opportunities Act would require water sus-tainability plans. These would provide for performance indi-cators and targets and financial plans and strategies tomaintain and improve water service. These tools should assistthe province and municipalities to implement full-cost ac-counting and recovery with less provincial prescription. Theyallow for consideration of issues faced by small, remote andrural municipalities.

Meanwhile municipalities are developing financial plansas required by the Safe Drinking Water Act regulations, whichare currently being phased in. 3. What about water quality on First Nation reserves? Rec-ognizing that the inquiry was under the Ontario Public In-quiries Act, Justice O’Connor made some recommendationsat the request of First Nations. He encouraged the federal gov-ernment and First Nations to adopt drinking water standardsfor reserves that are at least as stringent as standards off-re-serve in Ontario.

He observed that there were no legally enforceable drink-ing water standards for First Nation reserves, and also ob-served 22 high-risk First Nation water systems. Things havechanged very little in the past 10 years. There have been inex-plicable delays, even in developing the simple enabling legis-lation. And 40 years later, the spectre of mercury pollution inthe English-Wabigoon river system may be rising again.

Ottawa hopes to make good on its long-standing promisethat First Nation reserves will have access to the same qualityof drinking water that the rest of us enjoy. On May 26, 2010,the federal government introduced Bill S-11, the Safe Drink-ing Water for First Nations Act, which will allow it to draftlegally enforceable drinking water standards for First Nationcommunities. The enabling legislation would also allow for“regional flexibility,” with the enabling regulations likely tovary from province to province.

In an unusual move, the government’s proposed legislationwas first tabled in the Senate, rather than the House of Com-mons. Background information on the bill is posted promi-nently on the Indian and Northern Affairs Canada (INAC)website, and touted in government press releases, so we expectthis is something the government intends to pursue, althoughBill S-11 had not yet passed second reading when the Senateadjourned for its summer break.

Although the federal Protocol for Safe Drinking Water forFirst Nations Communities already sets out standards for thedesign, operation and maintenance of drinking water systems,there is no legislative framework to ensure compliance. To fillthis gap, Ottawa says it will review provincial and territorialregulations “to identify areas that can be adapted into federalregulations, while at the same time, allowing for regional dif-ferences, and recognizing the unique water challenges facingmany First Nation communities.”

Bill S-11 would allow the adoption of a wide range of reg-



Drinking Water

ulations:• standards for the quality of drinking

water on First Nation lands;• protection of sources of drinking

water;• location, design, construction,

modification, maintenance, operation and decommissioning of drinking water and wastewater systems;

• monitoring, sampling and testing of drinking water and wastewater, and the reporting of results;

• emergency measures in response to the contamination of water on First Nation lands;

• training and certification of system operators; and

• making remediation orders where standards have not been met.Provincial and territorial drinking

water standards could be incorporatedby reference into the federal regulationsto be promulgated under the Act. Theseharmonized rules could enhance oppor-tunities for First Nations to coordinatetraining or even share water treatmentand distribution systems with off-reservecommunities.

Walkerton is now the site of a state-of-the-art operator training facility.

The Act would automatically apply toall First Nation communities, except self-governing First Nations that are operatingunder comprehensive self-governmentagreements with the government ofCanada. However, self-governing FirstNations could be made subject to the leg-

islation following written agreement withthe minister.

Once the legislation receives royal as-sent, Ottawa will consult with First Na-tions, regional First Nation organizations,the provinces and territories, and otherstakeholders on the development of the

According to INAC, as of March2010, 114 First Nation communitiesacross the country were under drinkingwater advisories and 49 First Nation

regulatory regime. These discussionswould also address compliance and en-forcement mechanisms. The proposedlegislation follows at least some of therecommendations made by the Office ofthe Auditor General, the Expert Panel onSafe Drinking Water for First Nations,and the Standing Senate Committee onAboriginal Peoples.

The Bill has already triggered someopposition. According to Assembly ofFirst Nations National Chief Shawn A-in-chut Atleo, “First Nations [would]need infrastructure, training and supportto meet the requirements of the new reg-ulations. Regulations without the capac-ity and financial resources to supportthem will only set up First Nations to failand to be punished for this. In my view,we must address the ‘capacity gap’ aswell as the ‘regulatory gap’.”

Chief Atleo also said that Bill S-11could negatively affect First Nationwater rights. According to section 6 ofthe proposed legislation, regulationsmade under the act prevail over any lawsor by-laws made by a First Nation, aswell as over the land claims agreementor self-government agreement to whicha listed aboriginal body is a party.

These provisions were the subject ofsome concern during the recent firstreading debate in the Senate.First Nations Water and Wastewater

Action Plan extendedAt the same time that Bill S-11 was

introduced, Ottawa announced a two-year extension of the First Nations Waterand Wastewater Action Plan to invest anadditional $330 million in water andwastewater facilities. The action plan isalso funding the National Assessment ofFirst Nation Water and Wastewater Sys-tems to provide a more accurate accountof water and wastewater needs. The re-sults of the assessment should be avail-able later this year.

Between 2006 and 2012, Ottawa willhave invested over $2.3 billion in FirstNation water and wastewater infrastruc-ture, including the First Nations WaterManagement Strategy ($270 million), thePlan of Action for Drinking Water ($60million) and the First Nations Water andWastewater Action Plan ($660 million).

Another $183 million was allocatedto drinking water and wastewater infra-structure projects to address health and

water systems were classified as “high-risk,” down from a peak of 193 high-risksystems in 2006.

within the allocated schedule. Materialtake-offs modeled in excess of 300pieces of equipment and 550 major pip-ing process lines. The estimating processtook 40% less time than anticipated.

One aspect of the model work, thepiping material take-offs, was especiallysignificant when it came to estimatingcost. In desalination plants, two majorexpenses are specialized stainless steelpipe, and large-bore (up to 2 m diameter)glass-reinforced plastic pipe. By usingthe model, Hatch was able to optimizeplant design for the most efficient use ofthese expensive materials.

The site itself created design chal-lenges, as it was bound on one side bythe creek identified as culturally impor-tant and was on steeply sloped land, witha height difference of 30 m from theshoreline to the main access road. Thedesign team was able to compare multi-ple options to arrive at a system thatmade the best use of gravity and avail-able access.

As Australia suffers throughone of the most serious andsustained droughts in its his-tory, cities are devising in-

creasingly innovative responses. Adelaide, the capital of South Aus-

tralia, has been operating under perma-nent water restrictions. To take advantageof the port city’s abundant salt water sup-ply, South Australia Water (SA Water)commissioned a daily 100-gigalitre-ca-pacity, reverse osmosis desalination plantto supplement the freshwater supply, takepressure off the existing rainwater catch-ment system, and allow water levels toregenerate. When completed, the plantwill supply from one-quarter to one-halfof Adelaide’s water needs and will beAustralia’s biggest desalination plant.

After a lengthy qualification process,the Adelaide Aqua consortium (ACC-IONA Agua, United Utilities, McConnellDowell and Abigroup Contractors) wasshort-listed. SA Water invited three or-ganizations to provide detailed fixed-priceestimates and other design details in orderto make a decision based on three factors:design efficiency and sustainability, min-imal environmental impact, and overallcost of construction, operation and main-tenance.

To provide the level of detail re-quested, Adelaide Aqua had to fast-trackdesign within 12 weeks. The consortiumcontracted with Hatch Associates tocarry out front-end engineering and de-sign (FEED).

Hatch opted to do this work based ona 3D model, for two reasons. First,building a model was the best way to gettruly accurate cost estimates. With amodel, material take-offs could be basedon pre-designed and proven piping lay-outs, and plant layout could be opti-mized with 3D tools and comparison ofdifferent options. Second, the 3D modelcould be used to visualize plant impacton the environment, the community, anda culturally important site.

Using Bentley’s PlantWise software,the Hatch team generated a 3D model ofthe reverse osmosis process building, in-take pump station, outfall energy recov-ery shaft, and other utility buildings

To mitigate the effects of saline con-centrate release, a detailed diffusion planwas also devised. Rapid virtual proto-typing was used to determine the mostefficient layout; after a base reverse os-mosis process building layout was de-fined, three additional building layoutswere created and evaluated against thebase for overall costs, efficiency, ap-pearance and other factors.

Reverse osmosis is an energy-inten-sive process. In fact, so much energy isrequired that making the case for a de-salination plant on sustainability groundscan be difficult. To counter this, energyrecovery devices were included in theprocess building and outfall shaft, andsolar energy panels will be installed onthe process building roof. The energy re-covery devices use energy stored in thebrine to boost the output of the high-pressure pumps feeding the reverse os-mosis units. In the outfall shaft, energyrecovery turbines will produce electric-

the 3D model as a key factor in winning

and structural commodities, and was themain tool for developing accurate costestimates.• Substantial time savings were realized,compared to traditional 3D modeling. Theestimated 750 hours of modeling time

In a 2009 press release, AdelaideAqua suggested that the plant eventuallycould be expanded, and, two years afterinitial completion, could be producingas many as 3 gigalitres per day. That

would make the Adelaide plant thelargest of its kind in the world and wellable to meet over half of the city’s waterneeds.

no obvious trends showing an increaseor decrease in the amount of precipita-tion in the region, the conclusion wasthat climatic variables were not affectingthe water level of Nipissar Lake.

After the volume calculation and cli-matic variable analysis, FSC determinedthat the volume reduction in NipissarLake was due to the increase in waterusage caused by population growth. Thelake’s natural recharge rate fails to meetRankin Inlet’s water usage. Using thetwo known water volumes, an annualvolume decrease of 44,035 m3/year wasdetermined.

The same data were used to calculatethat Rankin Inlet’s annual water usagewas 355,824 m3/year. The difference be-tween these two numbers is the maxi-mum discharge available from NipissarLake that will not negatively affect thelake volume and create a water deficit.In effect, 311,789 m3/year is the maxi-mum rate of discharge that NipissarLake can sustain, and this amount has al-ready been reached and surpassed.

Based on the projected population in-crease of Rankin Inlet and its currentwater usage, Nipissar Lake could fail tobe an adequate source of water as earlyas 2015. This date could be extended byreducing the amount of water withdrawnfrom the lake, but even the best-case sce-narios show Nipissar Lake failing to be

In 2009, the government of Nunavutcontracted FSC Architects & Engi-neers (FSC) and Resource Man-agement Strategies Inc. (RMSi) to

complete a water supply capacity, con-sumption and conservation study for thehamlet of Rankin Inlet.

The hamlet and residents had becomeconcerned about the dropping level oftheir primary water source, NipissarLake, which is located 1.5 km northwestof Rankin Inlet and provides water to thetown through an underground piped utili-dor system. Rankin Inlet has seen asteady increase in population over the last15 years, from 1,845 in 1994 to 2,499 in2009. The purpose of the study was to de-termine if the volume reduction in Nipis-sar Lake was a result of climatic variablesor increased municipal consumption.

The first step in the study was to ac-curately survey the current water level ofNipissar Lake and compare it with knownwater levels from a previous study, to de-termine the actual drop in volume. A1995 survey had determined the volumeof the lake to be 3,469,780.00 m3. FSC’ssurvey in 2009 found the volume to be2,809,259.60 m3, for a difference of660,520.40 m3.

Next, climatic variables were ana-lyzed for the region. Historical precipi-tation rates were analyzed for the yearsbetween 1981 and 2008. As there were

an adequate water source by 2022.Rankin Inlet is at the point where

water conservation and reduction meth-ods will not stop the current waterdeficit, so the lake will have to be artifi-cially filled to maintain safe water levelswithin the next five years.

Pipeline system designFollowing this study, the government

of Nunavut contracted FSC Architects &Engineers earlier this year to provide aschematic design report for a pipelinesystem to augment natural replenish-ment of Nipissar Lake. The system willconnect First Landing Lake and Nipis-sar Lake to fill Nipissar Lake artificiallyand satisfy Rankin Inlet’s water demandfor a minimum period of 20 years.

There were several factors that had tobe considered in the design require-ments, including population growth,water demand, seasonal constraints,length and size of the pipeline, andpump size and capacity.

FSC analyzed population growthrates of 2%, 2.5% and 3%. For example,with a current population of 2,499 and a3% population increase over each of thenext 20 years, the population of RankinInlet is projected to be 4,649 in 2030.With this scenario, and with the currentconsumption rate of 469 litres consumedper day (LCPD), Rankin Inlet wouldconsume 795,818 L/day.

long, and the pipeline will be con-structed of high-density polyethylene(HDPE) for optimal flow capacity, dura-bility, flexibility and cost. After analy-sis, FSC recommended a 4-inch, 75-hppump and a 200-mm pipeline. These arethe best options in terms of both systemcost and functionality, and will meet thedesign requirements of Rankin Inletwater consumption.

Augmentation of the natural replen-ishment of Nipissar Lake will be in op-eration by the pumping season.

The proposed pump and pipeline sys-tem will ensure that the hamlet will havea clean, safe and reliable water sourcefor the next 20 years, and will begin toeradicate the current water deficit.

Water Treatment

The PVWC has three modern treat-ment facilities, numerous reservoirs,pumping and booster stations, and hun-dreds of kilometres of water transmis-sion pipelines. The infrastructure coversan area of about 7,000 sq km and sup-plies water exceeding the Guidelines forCanadian Drinking Water Quality. “Infact,” says Gord Martel, CEO of thePVWC, “we can handle pretty much anyregulation they throw at us now.”

Fertile ground for a water cooperative

Agro Manitoba was well-suited forthis initiative from the start. The com-munities are all located in one of the flat-test regions in the world. Distributionbetween communities has been as easyas would be expected when there are nomountains, or even hills, in the way.

Many small communities and farmswere operating with limited infrastruc-ture or none at all. They all had the sameproblems. They either relied on chroni-cally dry wells or wells with difficultwater (contaminated, hard or untreat-able). If they were without a well, theyrelied on surface water and wrestledwith its associated treatment challenges.They faced water shortages in an areawhere irrigation was critical to the localeconomy, and they had very limited re-sources with which to improve systemsindividually.

The co-op is now fully user-financedand regulated through the Manitoba Pub-lic Utilities Board. Without the co-op,each municipality would have to shoul-der the administrative, maintenance andoperational burdens of its own system.

Martel reports that, over the years, oneof the greatest challenges in operating theshared system has been keeping up withchanges in regulations. This has been thecase for most owners of water supply sys-tems in Canada since Walkerton.

Costs associated with upgrades ne-cessitated by growth and stringent regu-lations were often more than theindividual municipalities could handle,even when sharing the burden. Martel

Pembina Valley Water Coopera-tive (PVWC) is a pioneer in thesustainable sharing of water re-sources across communities

where sources are limited. Formed in1991, it includes one city, eight towns andnine rural municipalities, and now serves50,000 people in Manitoba. The PVWCis a model of stakeholder cooperation andwater infrastructure optimization.

Manitoba is unique in water infra-structure for several reasons. Largercommunities in the province depend onsurface water sources, usually makingsmall water systems not viable, becausesurface water woes, such as THMs,colour, turbidity or parasites, are diffi-cult to treat at that scale. Though Mani-toba is well known for floods, it alsofaces the likelihood of drought everyfour or five years.

On the upside, located at the down-stream end of the Hudson Bay water-shed, Manitoba receives fresh waterfrom Alberta, Saskatchewan, NorthDakota, South Dakota, Minnesota andOntario. At the geographic centre of allthings North American, the province isideally situated to lead in “wet” indus-tries such as livestock production andprocessing.

For the most part, small communi-ties have been able to sustain themselvesin the face of rural depopulation becauseof the opportunities created by the abun-dance of water. But, with most of thiswater going to the sparsely populatednorth and east, it doesn’t help “Agro”Manitoba, the south, which is consid-ered a chronic drought area.

Enter the PVWC. What began as arough concept in the drought years of the’80s became the first regional water co-operative in Manitoba and perhaps oneof the earliest in Canada. Originally, itreplaced eight local water treatment fa-cilities which produced very poor qual-ity water. Farms and small towns nowhave access to piped water, a benefit thatis reflected in property values and boostsrural economies.

says what made this easier for the co-ophas been an established process of cost-benefit analysis and a culture of sharingamong stakeholders. Users and ownersare accustomed to the idea of give andtake.

He adds: “Regulators love us, be-cause they only have to work with oneentity when regulating and monitoringmultiple communities and farms.”

Operating on the assumption that allmembers would need to see balancedbenefit across the region to continuesupporting the cooperative, the PVWChas always conducted surveys of peoplewho live along the pipelines.

Capacity was recently tripled at thewater treatment facility in Morris, atown of 1,700, located 50 km south ofWinnipeg on the Red River. This is thesecond largest facility in the co-op. TheMorris plant is one of the first surfacewater treatment plants in Canada to usea multi-membrane process, and it hasbecome the benchmark for surface watertreatment in Manitoba.

Morris needed additional capacityand higher water quality, and to removedirect reliance on the river. This wasachieved by constructing a large storagepond that could store clean water for upto a year. This flexibility would help theco-op survive river events, which aresignificant and frequent in Manitoba.Over the years there have been oil slicks,emergency dumps by industrial facilitiesupstream in the US, and a number ofcontamination events. The province isalso bracing for “the Big One,” the one-in-a-thousand-years Red River flood,which forecasters say could happen atany time.

The importance of flexibilityBy nature, a water cooperative is a

master plan. One of the distinguishingfactors in Pembina Valley, however, hasbeen its flexibility. A master planningstudy in 2003 identified numerous waysto expand each facility, and conceptual-ized various pipeline twinning andbooster pumping alternatives, complete

with cost budgets.The Roland reservoir and pumping

station, which were developed shortlyafter the study, can draw from the Mor-ris or Stephenfield plants, or both, andcan feed pipelines to either Winkler orStephenfield, or both. This componentof the system can transfer spare capacityamong the three regional subsystems, ormaintain service to a district in the eventthat another component in that districtmust go offline for repairs.

The PVWC model and other provinces

The benefits of a cooperative in thecase of Agro Manitoba are clear: im-proved and varied water sources in achronic drought area, and access forsmaller communities to better treatmenttechnologies and to more qualified op-erators who are not always available ina rural area.

What we are seeing in many provincesis the concept of “forced” amalgamationor regionalization; in other words, provin-cial policy may lead to the joining ofsmall municipalities into a larger (re-gional) municipal structure, with the newstructure assuming responsibility forwater and wastewater services.

So, fertile ground or not, the spirit ofthe cooperative concept is spreading,clearly in some cases in a top-down fash-ion. Communities may not always feelthe “love” that the PVWC gets from reg-ulators, but the results have the potentialto be comparable in the long term.

Pembina Valley still has to run a tightship to manage debt and wait patientlyfor the financing needed for further in-terconnections. In recent years, usershave been diligently implementing waterconservation measures, causing a reduc-tion in the volume of sales for the co-op.

“This is hardly a change we can stand inthe way of,” says Martel. “So, instead,we have to manage our way through itas we always have.”

They can re-move dangerous pathogens like E.coli,fecal coliform, salmonella and others.

Fortunately, beneficial organisms aremore tolerant to cupric ions, so they re-main to perform their digestion function.

Fermenting organic waste commonlyproduces noxious gases like ammonia,hydrogen sulphide, methane and sulphurdioxide. By adding cupric ion formula-tions as described, fermenting liquidwaste can be decomposed with little orno noxious gas production. Furthermore,the handling characteristics of the wastecan be improved by maintaining a uni-form liquid mass with predictable vis-

Designers, owners and opera-tors of wastewater treatmentsystems must deal with manyissues in order to ensure ac-

ceptable environmental performance aswell as reasonable capital and operatingcosts. The objective in selecting a waste-water treatment system for a resort, asmall community, a food processing com-plex, or for livestock manure, must be toprovide long-term, satisfactory and cost-effective performance.

Using a wastewater additive contain-ing cupric copper ions is a way to avoidthe most common problems that canplague small wastewater treatment plantsand lagoons, including: noxious odorsfrom fermenting organics; slow decom-position of organic waste; algae compet-ing with bacteria for nutrients; excessiveenergy consumption for aeration; and, ef-fluent discharge outside acceptable pa-rameters.

Cupric copper products, which are

cosity. This facilitates clarification anduniform digestion. It also adds to itsvalue as an organic fertilizer.

If the waste is discharged back intothe environment, the treatment will pro-vide a reliable means of meeting waterquality standards.

These products suppress species ofbacteria that produce greenhouse andother nuisance gases, yet have littledetrimental effect on other fermentationand BOD/COD reducing bacteria. Bac-teria levels in pre-discharge tanks, or la-goons, respond quickly to treatment dueto the hydrophilic nature of properly for-mulated products.

In many applications, effluent dis-charge regulations may not be the pri-mary reason for treatment. This additiveeasily achieves and maintains odor con-trol. It also provides other benefits suchas reversing and preventing solids build-up, as well as reducing the population ofpathogenic bacteria. Copper sulphate isnot used in these applications simply be-cause it is unable to maintain a biologi-cally active copper ion. It, therefore,precipitates quickly in this harsh envi-ronment.

type of bacteria uses extra-cellular en-zymes to cut ammonia from molecularstrings. They are mostly aerobic and aresensitive to copper. Therefore, biologi-cally active cupric copper ions play akey role in controlling entire populationsof these bacteria. The right form of cop-per ion in the mass remains in its activeionized form to kill ammonia-producingbacteria, and allows other carbon diox-ide (CO2) producing aerobic bacteria tosurvive.2. Nitrifying bacteria. This type of bac-teria ingests molecular strings containingammonium compounds and produces anodorless precipitate by using oxygen (O2)from those compounds. This bacteria isexclusively aerobic and considered moreresistant to low levels of copper. Anotherimportant characteristic of these bacteriais that they are developmentally inhibitedby the presence of ammonia gas. Cupricions can give nitrifying bacteria an op-portunity to thrive, by reducing the pop-ulations of ammonia-producing bacteria.3. Sulphur-reducing bacteria. Thismainly anaerobic digesting bacteria usessulphate (SO4) instead of O2. The result

is that instead of having CO2 as a by-product, these bacteria produce hydro-gen sulphide gas (H2S). In liquid waste,active cupric copper reacts with H2S,changing it to a new sulphurous precip-itate, copper sulphide (CuS). CuS isquite stable and normally will not re-dis-solve. By means of converting H2S andby killing sulphur-reducing bacteriawith a cupric ion, H2S emissions can beeliminated.4. Methanogenic bacteria. This type ofbacteria is anaerobic in nature and, gen-erally, can only survive in areas whereoxygen is extremely scarce. This speciesdraws oxygen from water for its diges-tion process. The result is methane(CH4). Cupric ions, that are self-mixingand capable of reaching the depth of themass, reduce this population. This haltsand reverses waste solidification and re-duces methane gas emissions.5. Anaerobic production of methanegases. If the mass is totally starved ofoxygen, both in O2, and SO4 forms, thenthe bacteria will not be able to digest car-bohydrates as a methane string (CH4O),a very noxious gas. Cupric ions reduce

this type of gas production by killing theexcess bacteria population, leaving oxy-gen resources at par to reduce the BODof the mass.

Benefits of cupric copper additiveTypical benefits of using a cupric

copper additive are: significant odor re-duction; elimination of algae; clarifica-tion of water; elimination of worms, orsnails; 90% BOD reduction; stabiliza-tion of pH; 100% faecal/E.coli bacteriaregulation; 90% total suspended solidsreduction; 78% ammonia reduction. Compliance with effluent standards

These systems are typically used insingle or multiple lagoons, or in contin-uous trenches containing fermentingwaste. Cupric ion additives may be in-jected at any point in the treatmentprocess depending on site-specific con-ditions and objectives. Cupric ion addi-tives have been successful in singlelagoons, clarifying ponds, effluent pol-ishing ponds, and sludge beds.

when plastic pipes were introduced.During the 1950s and 1960s, a pe-

riod of rapid growth in the City of Wa-terloo, approximately 4,000 residentialsewer laterals constructed of black fibrepipe were installed.

Soon after the installation of thoselaterals, homeowners began experienc-ing sewer back-ups due to the collapseof pipes. Initially, the failed house later-als were replaced by new pipes, usingopen-cut excavation from the houses tothe streets. The open-cut constructiontook several days to complete, was dis-ruptive to both homeowners and city res-idents, and cost approximately $6,500per lateral.

Since the homeowner owned the lat-eral, the construction cost was sharedbetween the homeowner and the City.Due to the large number of prematurefailures and construction issues, it de-cided to assume the full cost of replacing

In the early 1990s, the City of Wa-terloo, Ontario, began experiencingpremature failures of sewer lateralsconstructed of black fibre pipe

(also known as Orangeburg or Bermicopipes) that had been in service for lessthan 20 years.

Black fibre pipes, 51 to 200 mm (2 to8 in.) in diameter, are compressed paperfibre tubes that are vacuum-impregnatedwith bituminous coal tar pitch to form apipe composed of approximately 25%fibre stock and 75% bitumen.

During World War II, governmentsmandated limited domestic use of steelto aid the war effort. This, and the lowermanufacturing cost of black fibre pipecompared to steel, clay and concretepipes, led to the rapid usage of blackfibre pipe for sanitary laterals, drainsand conduits. It remained a popularchoice for sewer laterals following theend of the war and until the late 1960s,

failed black fibre pipe sewer laterals. Asa result of this decision, it had to assumea $26-million liability.

In 1994, the City of Waterloo and theUniversity of Waterloo entered into apartnership to explore low-cost, less dis-ruptive methods of replacing black pipesewer. This partnership led to replacingthe failed laterals by pulling a pipebursting tool, which was attached to ahigh-density polyethylene pipe, from asmall excavation made inside the base-ment to a small excavation made at thestreet.

The new trenchless constructionmethod allowed the lateral replacementto be completed within a day, with littledisruption to residents. It also reduced thecost of a lateral replacement from $6,500to $4,500. The $2,000 cost savings foreach lateral reduced the City‘s replace-ment liability by approximately $8 mil-lion.

In 1994, the Centre for the Advance-ment of Trenchless Technologies (CATT)was founded at the University of Water-loo through a partnership between theUniversity, the City of Waterloo, the Na-tional Research Council of Canada, and25 founding municipalities, industrialequipment and material suppliers, con-tractors, consultants, and gas companymembers.

CATT, with the help of its members,has also developed trenchless technol-ogy short courses that promote the useof good practices and design of success-

simply claim to be environmental pro-fessionals once it has full backing fromthe environment industry in its entirety.

At the 2010 GLOBE Conference, aMemorandum of Understanding wassigned between ECO Canada and theEnvironment Institute of Australia andNew Zealand (EIANZ). The documentdemonstrates a mutual understanding ofthe growing need for professional stan-dards and certification that are recog-nized both locally and internationally.

In May, the project lead for the NovaScotia Ministry of Environment an-nounced his support for the proposed Li-censed Environmental Site Practitioners(LESP) Program, stating that the provinceof Nova Scotia would recognize ECOCanada’s certification, among others, asqualification to sign reports related tocontaminated sites.

In August, ECO Canada’s seven des-

With recent events such asthe BP oil spill, environ-mental professionals andemployers alike are be-

ginning to realize how past and currentpractices affecting the environment havethe potential to put the public at risk.

Additionally, industry personnel havebecome acutely aware of the need forspecific competencies, skills, and train-ing within the workforce. In a sectorwhere the range of specialization is vast,the development of certification withstrong regulatory support takes time.

For over a decade, ECO Canada (En-vironmental Careers Organization) hasoffered professional certification throughseven designations that formally recog-nize the unique skills and knowledge ofenvironmental practitioners. To date, thisis a voluntary certification program; itwill only be able to wean out those who

ignations merged to form what is nowthe Environmental Professional (EP)designation, which demonstrates an en-vironmental professional’s commitmentto accountability and career develop-ment, as well as their desire to remainon top of current practices. It also offersthird party validation of an individual’senvironmental competencies, as certi-fied members are measured against in-dustry-verified National OccupationalStandards for environmental employ-ment.Supplying environmental assurance

In becoming certified, all environmen-tal professionals are required to abide bythe Environmental Professional Code ofEthics. The Approvals Board ensures ad-herence to this, in addition to monitoringthe application of disciplinary measuresand overseeing the professional develop-ment of certified members.

Environmental professional certification – how important is it?

Events such as the Canadian Environmental Conference and Tradeshow, provide much needed learning opportunities forenvironmental professionals.


There is a strict disciplinary process,with clearly detailed procedures shoulda complaint be filed against a certifiedmember. This process also providesguidelines for disciplinary measures thatmay be applied in cases where a certi-fied member is found to have contra-vened the EP Code of Ethics.

What are National OccupationalStandards?

Occupational standards consist of thecompetencies required to perform workin a particular occupation. They are a setof statements describing the standardacceptable skills and knowledge require-ments of professionals. National Occu-pational Standards (NOS) are consideredthe benchmarks against which people ofa particular occupation measure theirlevel of performance and competency.They are the backbone of the certifica-tion process.

ECO Canada’s National Occupa-tional Standards for environmental em-ployment are compiled using a processthat relies heavily on broad-based inputfrom people working in environmentalfields. Using this bottom-up approach, inconjunction with the guidance of seniorenvironmental experts, ensures that thestandards are of high quality and rele-vance. This creates an accurate depictionof current and emerging competencies inthe many subsectors of environmentalemployment.

The NOS for Environmental Audi-tors, developed by ECO Canada, areconsistent with national and interna-tional standards for environmental audi-tors. The NOS for Greenhouse GasProfessionals are aligned with the inter-national standards in this field (ISO14064 parts 1, 2, and 3, ISO 14065, ISO14066).

NOS are updated approximately everyfive years to ensure that they remain ac-curate and reflective of the current reali-ties of environmental employment.

What about post secondary institutions?

As environmental employment con-tinues to develop and mature, definingthe scope of environmental professionalactivities and competencies benefits notonly the environmental workforce, butalso serves to inform the academic com-munity of the emerging needs of thelabour market.

Currently, 16 post-secondary institu-tions across Canada are integrating EPcertification into the environmental pro-grams they offer, thereby assisting theirstudents in graduating as EnvironmentalProfessionals in training (EPt). Partner-ships such as these are seen as one keyway to promote the growth and recogni-tion of the environmental profession.

What does the future hold for EP?In conjunction with the successes of

this year, new initiatives have focused onbuilding the community of Environ-mental Professionals in locations acrossCanada. Eight regional chapter leadershave been selected to build up connec-tions, opportunities, and recognition ofthe designation in their province.

The first annual general meeting ofeach chapter of Environmental Profes-sionals will take place between Septem-ber 2010 and June 2011, in conjunctionwith a networking lunch and workshop.

unlikely. Mr. Killoran realized he had torethink their approach and find a way toleverage technology. He decided to mon-itor flow in high volume areas within thecollection system. The Township selectedStingray Level-Velocity Loggers fromGreyline Instruments because they areportable, work in partially-filled pipes,and enable technicians to retrieve waste-water flow data without entering man-holes.

The study of the Glen Walter systemwas conducted from May 16 to June 9,2006. The ultrasonic sensors were in-stalled in seven different manholes, forperiods of three to five days. To capturedetailed flow information, the Townshipset the Stingrays to take readings at 10second intervals.

To deploy each unit, a township tech-nician selected a manhole location, at-tached a stainless steel bracket in theinfluent pipe, then mounted the sealed,ultrasonic sensor into it. The technicianconnected the sensor cable to the water-tight electronic logging unit and hung itinside the manhole. The logger recordedthe date and time, water level, velocity,and temperature.

During the study, the TownshipSensor installed in manhole inlet pipe.


Filtration

Five Orival Model ORG-080-LS auto-matic self-cleaning filters were mountedon a 16” manifold.

A 16” pneumatically actuated by-passvalve, incorporated into the manifold sys-tem, can be opened automatically shouldthe filtration system controller sense afault in the filtration process. The con-troller also has a set of dry contacts forconnecting an alarm system for fault sit-uations. An 8” manual butterfly valve waslocated at each filter inlet and outlet toallow the isolation of any individual filterfor maintenance or repairs.

Highly sophisticated processesare used to produce pharma-ceuticals, and cooling is avery important component of

these processes. The twin-cell water cooling tower at a

large pharmaceutical plant also serves asa wet air scrubber for odour control.Plant engineers recently discovered thatthe small 400 gpm side-stream, four-bagfiltration system on their 5,300 gpmcooling tower system did not provide theprotection needed for heat exchangers,condensers and vessel cooling jackets,scattered throughout their facility, in ad-dition to an 800 ton chiller.

Also, changing the bags based on adifferential pressure alarm was labor-in-tensive and not always done consistently.

So, they began looking for a full-stream filtration system to filter the5,300 gpm flow, with a 40-50 psi operat-ing pressure down to 100 microns. Spaceon an outdoor concrete pad was very lim-ited. To make matters worse, the concretepad’s surface was partially flat and par-tially inclined. Two pumps moved waterfrom the cooling tower basin up to an 18”header located about six feet above theconcrete pad. A third pump was to beadded when the filtration system was in-stalled to provide a backup.

Designing a solutionWhen designing mechanical filtra-

tion equipment, adequate hydraulic ca-pacity must be provided to maintainreasonable velocities through the inletand outlet flanges to minimize staticpressure losses.

Insects, sand, leaves, dust, pollen,cottonwood seeds and algae, as well asman-made debris such as paper, cupsand grass clippings, influence waterquality greatly. The filter flux must be ofappropriate value to meet the specificconditions of filtration degree, TSSloading, and type of solids. Filter flux isdefined as the flow rate per unit area ofscreen media, i.e., gpm/in2 of usablescreen surface.

Filters with a small footprint andlarge screen area were chosen to meetthe specific demands of this application.

Normally, the hydraulic piston, usedto move the self-cleaning mechanism(dirt collector) linearly inside each fil-ter, and the rinse valve are operated bythe water and pressure in the system.However, these filters would possiblyoperate during winter months whenfreezing would be a problem. Therefore,available industrial pressurized air isused to pneumatically operate the pis-tons and rinse valves.

The piston and rinse valve actuatoron each filter are filled with a glycolmixture that connects to an accumulator

tank. This tank is partially filled with theglycol mixture and then the tank is pres-surized with the industrial air supply. Asolenoid valve bleeds air from the tank,lowering pressure and, thus, allows therinse valve to open and the piston to op-erate when signaled by the controller toinitiate a cleaning cycle.

Cleaning cycles automatically occurwhen a 7 psi pressure differential devel-ops across the inlet and outlet manifolds,or when a preset timer lapses. Filter No.1 goes through its 15 second cleaningcycle, and then Filter No. 2, and so onsequentially until all five filters havecleaned themselves. Each filter remainsonline at all times with no disruption ofthe filtration process.

A design/build firm installed the fil-tration system, mounting the entirepackage about 12 feet above groundlevel on a mezzanine built on-site. Thisovercame the uneven concrete pad prob-lem and put the filters close to wherecooling water enters the building. Eachfilter is equipped with a liquid-filledpressure gauge and a 3-way selectorvalve. This allows the inlet pressure, out-

let pressure and rinse chamber pressureto be conveniently observed, with onegauge on each filter unit eliminatingvariations between gauges. Using thesepressures allows diagnostics to be run oneach filter.

Prudent use of appropriate chemicaladditives, routine blowdown, and properfiltration have resulted in exemplaryperformance, with no maintenance is-sues or process interruptions.

Troubleshooting the Sequencing Batch ReactorMichael H. Gerardi, Brittany Lytle

For years, operators have learned that they have little control over lagoon and fi xed fi lm sewage treatment systems. Tested in short-course situations by the author over the last fi fteen years, this guide gives operators a new understanding of how wastewater treatment processes with lagoons and fi xed fi lms function, and demonstrates that operators can have greater control over them than previously thought. It directs the material at operators instead of design and consulting engineers, while reducing the jargon, chemical equations, and kinetics; and provides necessary information for understanding biological conditions at the treatment process.

The greenhouse gas emissions calcu-lator and a literature review on emergingsubstances of concern have been com-pleted and are available on the CCMEwebsite.Municipal biosolids sampling study

Although various studies in other ju-risdictions have demonstrated the pres-ence of substances of interest, such aspharmaceuticals and personal care prod-ucts (PPCPs), in biosolids, a Canada-wide study to identify and inventory thesesubstances in biosolids had not been doneuntil now. The BTG first commissioneda literature review of available informa-tion and existing research. Subsequently,an analysis of biosolids and septage sam-ples from 11 wastewater treatment plantsin Canada was carried out.

The final report of the project willprovide: a list of emerging substances ofconcern present in Canadian biosolids;a comparison of the effectiveness of dif-ferent biosolids treatment processes forremoval of emerging substances of con-

The Canadian Council of Min-isters of the Environment(CCME) is the major intergov-ernmental forum in Canada for

discussion and joint action on environ-mental issues of national concern. The14 member governments work as part-ners in developing nationally-consistentenvironmental standards and practices.

Currently, Canadians produce morethan 660,000 metric tons of municipalwastewater biosolids each year. The an-nual cost of biosolids management is ap-proximately 50% of the total operatingcost of wastewater management.

To study and make recommendationson issues related to biosolids manage-ment at the national level, CCME estab-lished the Biosolids Task Group (BTG)in 2008. The desired outcome of BTG’swork is that local governments and otherbiosolids generators manage biosolidsunder a harmonized national policy andregulatory framework that clearly ad-dresses issues of risk; defines beneficialuse; instills public confidence; and pro-tects the environment and human health.

Municipal wastewater biosolids andseptage are including in the scope of theBTG work, but not separate industrial andcommercial biosolids derived, for exam-ple, from pulp and paper processing.

The initial work of the BTG included:

cern; and data on levels of these sub-stances in Canadian biosolids.

The analysis of the biosolids andseptage samples includes 57 pharma-ceutical compounds, 11 fragrances,three alkylphenolics (including Bisphe-nol A), nutrients, and the 11 metalswhich are commonly regulated in Cana-dian biosolids.

BEAM greenhouse gas emissions calculator

A consideration of increasing impor-tance, when evaluating biosolids man-agement practices, is the impact ofgreenhouse gas (GHG) emissions. Theobjective of the project was to develop aGHG calculation methodology for Cana-dian municipal biosolids generators andmanagers. This would evaluate the envi-ronmental impacts of current and futurebiosolids and sludge management op-tions, such as land application, compost-ing, incineration and landfilling, with orwithout energy recovery, includinganaerobic digestion.

A literature and background reviewwas undertaken to support subsequentdevelopment of the GHG calculator tool.The literature review identified GHGsources (debits) and offset (credits) op-portunities associated with biosolidsmanagement, determined and corrobo-

rated GHG emission factors, and sum-marized international GHG protocols.Biosolids management practices weresummarized for over 40 Canadian juris-dictions.

Based on the information gatheredthrough the literature and backgroundreview, a simplified GHG calculatorspreadsheet tool, known as the “BiosolidsEmissions Assessment Model” (BEAM),was developed.

Data and information for the valida-tion phase of the project were solicitedfrom nine Canadian municipalities. Par-ticipants were selected, based on theircurrent biosolids management practices,their leadership, the availability of data,and to provide regional representationacross Canada. Data and information re-ceived from these municipalities wereused to populate the BEAM and deter-mine net GHG emissions (tonnes of car-bon dioxide equivalents per dry tonnebiosolids) from their biosolids manage-ment practices.

Consultation with the participatingmunicipalities provided valuable feed-back that was used to refine the data andinformation requirements to optimize

the BEAM model.BEAM provides a flexible, user-

friendly model that can be applied tobiosolids management scenarios acrossCanada. As market incentives for GHGemissions reductions develop further,documentation using BEAM, combinedwith an independent verification step,could lead to the generation of mar-ketable carbon credits.

Legislative framework reviewPart of the mandate of the BTG is to

develop a Canada-wide approach for themanagement of municipal biosolids fo-cusing on policy and regulatory harmo-nization. One of the key steps to achievingthis goal was to undertake a federal andprovincial legislative review, with the ob-jective of outlining the current regulatoryframework, and identifying commonali-ties, inconsistencies, and duplications.

To obtain the information required, aBTG subcommittee designed a surveywhich included a questionnaire and a se-ries of comparative tables of standardsand requirements. Federal and provin-cial representatives of each jurisdictionon the BTG responded to the survey, andthe results were compiled and analysed.

The result of the survey is a pictureof the current Canadian legislativeframework, including a description ofthe roles and responsibilities of the dif-ferent jurisdictions, the procedure forapproving biosolids, applicable stan-dards and requirements, and complianceand monitoring.

Analysis of the survey informationindicates that certain policies (e.g., con-cerning pathogens, organic contami-nants) are quite similar across thecountry; whereas others (e.g., applica-tion rates, separation requirements) varybetween provinces.

Biosolids managementA Canada-Wide Approach for

Biosolids Management will be devel-oped from these projects and from addi-tional work to be carried out by BTG.Public consultation and information ex-change will be an important componentof its development. It is expected that thework will be carried out by the individualjurisdictions during 2010 and 2011.

Site Remediation

search Institute, which studied the flowof fluids underground. In particular, hisgroup examined cold, heavy oil produc-tion, the stability of boreholes, and anec-dotal information about how earthquakescan increase fluid flow in heavy oil fieldsin Alberta and Saskatchewan.

Their research eventually connectedthem with Dr. Tim Spanos at the Uni-versity of Alberta, who had developedhis own theory about liquid flow. Thetrio proved in a laboratory that sendingcontrolled bursts of fluid undergroundcould increase the flow of oil to extrac-tion wells. Patents were obtained and acompany was formed around the tech-nology shortly afterwards.

Field trials were conducted in Albertafrom November 1998 to February 1999.The trials provided very positive first-time-out results, demonstrating that thetechnology could increase oil recoveryby up to 34%.

After successfully marketing thetechnology to oil producers across NorthAmerica, Wavefront decided to apply thetechnology’s principles to facilitate un-derground remediation projects. Theprinciples of increasing the flow of flu-ids underground for the purposes of ex-tracting oil were the same for increasingthe distribution of remedial fluids un-derground. Instead of using pulses to“sweep” oil from underground, the tech-nology could facilitate remediation fluid

Underground remediation pro-jects can be costly and time-consuming for land de-velopers. Managers often en-

counter difficulties getting remediationfluid into close contact with target con-taminants. Numerous injection points arefrequently required, with fluid coming tothe surface instead of going underground,a phenomenon commonly known as day-lighting. Reaching contaminants in hard-to-access areas, such as under buildings,can be especially challenging.

Edmonton-based Wavefront Technol-ogy Solutions has developed an innova-tive process called Primawave that workswith remedial injection equipment al-ready being used on-site. The technologyhelps treat sites quickly, while reducingcosts by as much as 40%.

Fewer injection pointsPrimawave works by using powerful

bursts to disperse remediation fluid un-derground to reach contaminants effec-tively and with pinpoint accuracy. Ithelps reduce the number of injectionpoints with its increased efficiency,while still reaching contaminants over alarge area.

The process emerged from academicresearch that Wavefront President andCEO Brett Davidson conducted at theUniversity of Waterloo in 1997. He man-aged a group headed by Dr. MauriceDusseault, called the Porous Media Re-

being placed in close contact with con-taminants.

Underground remediation projectsoften require numerous injection pointsbecause the fluid does not spread readilyto affected areas. Instead, it passes un-derground through the path of least re-sistance, leaving contaminated areasuntouched, unless another injectionpoint is established.

Standard piping or fittings are usedto connect Primawave tools between theinjection pump and a standard injectionwell or direct-push injection point. Pri-mawave sends out powerful bursts of in-jected fluid up to 600 times per minute,depending on subsurface flow charac-teristics. The fluid is forced to movethrough the ground with greater unifor-mity, regardless of permeability or soilvariability.

Davidson compares how Primawaveworks to a water hose with a kink in it.The pressure from the tap drives thewater from the end of the hose at about50 to 55 pounds per square inch. With akink in the hose, energy builds behindthe kink.

“The host acts like an accumulator,”says Davidson. “People think that morepressure is being created but that’s notpossible. You can’t create pressure whenit’s still coming from your house. Whatyou’re doing is storing energy.”

When the kink is released, the stored

creasing considerably, protecting naturalhabitats is of utmost importance. Thequestion remaining is how to define theeconomic value of biodiversity in a cap-italist system.

According to Jean Cinq Mars,Québec’s Sustainable Development Com-missioner, the problem must be analysedwith regard to the central components ofsustainable development: biodiversity andplanning. The main utilitarian function ofbiodiversity is to provide human popula-tions with environmental services such asoxygen production, carbon sequestration,food production, and even the enjoymentof a beautiful landscape. These servicesare natural processes that can be cate-gorised as public and private goods.

For Jean Cinq Mars, the biggest chal-lenge remains the evaluation of these en-vironmental goods. “How to define theterritory of a watershed? How does oneevaluate the amount of carbon se-questered? What are the acceptable lim-its of habitat exploitation?”, he asks.

In Québec, there is no policy ensuringthe sustainability of regional ecosystems.For example, in aquatic ecosystems,cyanobacteria is always proliferating, be-cause of the presence of phosphorus due

In order to emphasize the interna-tional year of biodiversity enactedby the UN and UNESCO, environ-mental scientists presented their re-

flections as part of a seminar organizedby the eco-counselor of the Universityof Québec at Chicoutimi, in January2010.

Experts are struggling to find a defi-nition that grasps biodiversity’s com-plexity as it encompasses a diversity ofspecies, ecosystems, microorganisms,genes, and even populations. It also re-mains hard to measure biodiversity’seconomic value.

During the last few decades, the dis-course on biodiversity has grown in im-portance. It was initiated in 1992 with theBiodiversity World Summit in Rio deJaneiro, Brazil. It was then that the worldbiodiversity convention was created andratified by more than a hundred countries.

In order to significantly reduce bio-diversity loss, Kalemani Jo Mulongoy,the Principal Officer in charge of Scien-tific, Technical and Technological Mat-ters for the Secretariat to the Conventionon Biological Diversity, suggested thatsetting clear goals and quantitative ob-jectives could help slow down biodiver-sity loss. For instance, in the period from2010 to 2020, our governments couldput forward a plan to reduce ocean acid-ification and decrease total deforestationand overfishing by 50%.

According to Mr. Mulongoy: “We arecurrently in an irreversible period of bio-diversity loss. In 2005, we came to theconclusion that we have lost approxi-mately 30% of biodiversity due to anthro-pogenic perturbations to the ecosystems”.

Amazonian forest degradation andthe ever-growing expansion of Northand South African deserts are the mostserious environmental problems human-ity is facing. The idea of creating pro-tected areas comes as a solution to helppreserve these natural ecosystems, whileproviding an opportunity for furtheringour knowledge of biodiversity.

The market value of biodiversityIn a context where populations, con-

sumption, and global warming are in-

to improper use of chemical fertilisers. Laval University bioethics re-

searcher, Louis-Étienne Pigeon, pre-sented a valuation model, which wasdifferent to liberal and utilitarian ones.The strength of this model lies in itsability to harmonize the needs of differ-ent human populations with the preser-vation of nature. The approach aims toestablish clear preservation goals by so-liciting the involvement of local popula-tions through symposiums, publicdebates, and public gatherings.

Biodiversity must be preserved by ed-ucating citizens. The survival of biodi-versity relies on deep individual changein behaviour and societal transforma-tions. “Let us biodiversify our dailylives”, said Michèle S. Jean, the Presidentof the Canadian Commission for UN-ESCO, at the conclusion of this sympo-sium.

the world. The success of early industry at the harbour took a toll on

the environment. Permanent large-scale docks destroyed fishand wildlife habitat. Decades of unrestricted wastewater dis-charges from fish and vegetable processing plants contami-nated the water with high levels of nutrients.

PCBs from fish processing waste accumulated in the sedi-ment of the wetland and harbour over time. Fish and wildlifepopulations declined, contaminants accumulated in fish, caus-ing health-based restrictions on eating the fish. Poor water qual-ity and high nutrients from fish processing waste also causedthe growth of undesirable algae.

Past industry was not the only cause of contamination. Agri-cultural runoff and faulty private septic systems in the MuddyCreek watershed caused excessive nutrient and bacterial con-tamination.

The Ontario Ministry of the Environment and EnvironmentCanada initiated the Wheatley Harbour Remedial Action Planin 1987, to define and deal with the area's environmentallegacy. Key results included: • Local industries responded to the new legislative require-ments by investing more than $4 million to upgrade theirwastewater treatment facilities. • Forty homeowners in the Muddy Creek watershed took ad-vantage of $250,000 in federal grants to upgrade their faultyseptic systems. • Local landowners, with help from the Essex Region Con-servation Authority and the Essex County Stewardship Net-work, planted a total of 850 metres (2,789 feet) of native trees,shrubs and other vegetation as buffers along Muddy Creek.This work helped to stabilize eroded stream banks and to filterphosphorus, nitrogen and other contaminants from agriculturalsources. These buffer strips of vegetation also provide food andshelter for a variety of fish and wildlife.• The Ministry of the Environment and Environment Canadaassessed the contaminated sediment and found the low levels ofPCBs were having no impact on local fish and wildlife. Overtime, clean sediments have covered over the contaminated sed-iment, forming a natural cap.

Governments had created stricter regulations for industrialwastewater treatment in the 1970s and 1980s which had alreadyhelped control wastewater discharges by the time Wheatley Har-bour was designated an Area of Concern.

Environment restoredWater quality in Wheatley Harbour and Muddy Creek has

improved significantly as a result of actions taken to controland improve industrial wastewater, agricultural runoff and othersources of water pollution.

There are no new sources of PCBs entering the harbour.Phosphorus and bacteria levels have declined in response tostewardship actions taken by landowners to reduce agriculturalsources of contamination. E. coli bacteria that were enteringthe water have been significantly reduced due to upgrades toprivate septic systems.

Today the ecosystem is restored and Wheatley Harbour hasbeen removed from the list of Great Lakes hot spots.

Alexandre Allard and Danny Luong, fromCanada, recently received the StockholmJunior Water Prize from H.R.H. CrownPrincess Victoria of Sweden. Their re-search on biodegradation of the plastic,polystyrene, won them the prize.

“Expanded polystyrene (EPS) is agreat threat to the environment since itcontributes to the spread of toxins such asstyrene and bisphenol A into our waters.We hope that our method will be widelyused and consequently increase the waterquality in the world,” said the winnersafter receiving the prize.

The international Stockholm JuniorWater Prize competition brings togetherthe world’s brightest young scientists toencourage their continued interest inwater and the environment. Each year,thousands of participants in over 30 coun-tries join national competitions for thechance to represent their nation at the in-ternational final held during the WorldWater Week in Stockholm.

Increasing Montrealʼs watersupply during dry spells

Work was scheduled to have been carriedout this summer on the Rivière des MilleÎles, to allow its flow rate to be re-estab-lished. It involved shallow water dredgingat the mouth of the river, in order to in-crease flow out of Deux Montagnes lake.

Low snow accumulation levels thispast winter, coupled with a dry spring,caused a very low water level in the river.The fear was that, if the area experienceda hot and dry summer, water flow couldhave dropped to levels unseen in over 80years. The Rivière des Mille Îles providesdrinking water to more than 400,000 peo-ple in the north Montreal area.

The strategicplan will include development of goals forwater conservation and achievable reduc-tion targets, and activities for variousareas and sectors of the province.

The plan will include information onsimilar programs already in place in otherjurisdictions that may be applicable toManitoba. It will also identify potentiallegislative and regulatory changes to en-courage water conservation and effi-ciency, and identify potential applicationsfor recycling of grey water in Manitoba’surban municipalities.

BC approves CRD sewagetreatment plan

The British Columbia government has ap-proved a wastewater management strategyproposed by the Capital Regional District(CRD) that will treat up to 40 billion litresof sewage per year, before it is dischargedinto the Strait of Juan de Fuca. The strat-egy incorporates resource recovery, con-servation and innovation, and allows theCRD to start the implementation phase ofits wastewater management strategy andto meet its commitment to provide sewagetreatment by 2016.

Current sewage flows will be treatedat McLoughlin Point in Esquimalt. After2030, incremental sewage flows would betreated at a separate facility, potentiallyon the Westshore. The Saanich Eastsewage treatment facility has been re-placed with storage tanks to equalizepeak storm sewage flows. A biosolidsprocessing facility will be constructed atthe Hartland landfill.

The CRD will be required to monitorquality and volumes of wastewater dis-charged through the outfalls and mustcontinue to assess the impact of the dis-charge to the ocean to determine the needfor further treatment in the future.

Nearly 57,000 Canadians signed up forthe 2009 Great Canadian ShorelineCleanup to remove trash from shorelines.This initiative is said to be one of the sin-gle largest contributors to the Interna-tional Coastal Cleanup, and is the largestCanadian program.

With the longest shoreline of anycountry in the world, hundreds of thou-sands of litter items are collected everyyear. Last year, the program recovered40,799 cups, plates, forks, knives andspoons from 2,457 km of shoreline. Intotal, 160,914 kg of litter were collected.

Veolia Water developsWater Impact Index

Veolia Water North America recently un-veiled its Water Impact Index, which al-lows for a comprehensive assessment ofthe impact of human activity on water re-sources. The Index expands on existingvolume-based water measurement toolsby incorporating multiple factors, includ-ing consumption, resource stress, andwater quality.

Fresh water availability has been pre-dicted to become a major limitation fac-tor for growth for cities and industries inmany locations around the world, and the

need to understand and quantify the im-pact on water resources is becoming es-sential to maintaining their sustainabilityand future prosperity. This reality re-quires an understanding of the factorsneeded to make the most appropriate,sustainable decisions. The new tool willprovide additional parameters that deci-sion-makers need to make these deci-sions.

The Water Impact Index establishesthe impact of human activity on water re-sources and provides a methodology forestablishing the positive and negative im-plications of how water resources aremanaged. The study is the first to take thebalance of both carbon and water intoconsideration, and assigns a value towater, based on quality, quantity and re-source stress.

New guideline for using reclaimed water for

flushing

On-site reclaimed/gray water systems in-clude the collection and treatment ofbath, laundry, and wash basin wastewaterfrom domestic dwellings, for non-potableuses such as toilet and urinal flushing.However, the presence of pathogenic mi-croorganisms and some chemicals maypose a health risk if this water is improp-erly treated, or if it is used for purposesother than toilet or urinal flushing.

Health Canada has developed a newguideline to ensure that the use of re-claimed water does not pose a publichealth risk. It provides benchmark levelsfor some health-based and aesthetic indi-cator parameters to ensure the safety of

Parkson helps Mexican WWplant double capacity and

cut energy use

Recently, the Parkson Corporation in-stalled 304 HiOx® UltraFlex aerationpanels at a wastewater treatment facilityin Hidalgo, Mexico, which is located 40miles northwest of Mexico City.

Treated wastewater from the plant isused by a nearby power generation sta-tion, and an oil refinery. The existingwastewater plant was no longer able toproduce the required quantity of waterneeded for these industrial applications.The HiOx installation has more than dou-bled the wastewater plant's consistent ca-pacity to 11.4 MGD and peak flowcapacity of 13.7 MGD, a 140% increase.Increased water production will allow thepower generation plant and refinery torely significantly more on recycled waste-water, versus scarce freshwater.

In addition to a 46% reduction in en-ergy use, the plant has also experienced96% BOD reduction levels. For moreinformation, E-mail: [email protected]

Mozart for Microbes

A sewage treatment plant near Berlin,Germany, is playing Mozart to its bio-mass-eating microbes, hoping the sweetsound will make them work harder! It ishoped that the Austrian composer willsave the facility as much as 1,000 eurosper month. The waste treatment facilityhas been testing a special stereo systemover the past few months after an Aus-trian plant said that Mozart made theirsewage-eating micro-organisms performbetter, helping to cut costs.
