ProMix is an in-line polymer preparation station for the processing of liquid polymers. 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 unit is designed for wall mounting and thus requires only little floor space.

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.

aware that there have been natural gasdrilling rigs in Lake Erie for almost 100years. Also, that there are still an esti-mated 46.1 million barrels of oil and3.01 trillion cubic feet of natural gasunder it. In total, it is estimated that311.7 million barrels of oil and 5.23trillion cubic feet of natural gas still lieunder the US side of the Great Lakes.

While drilling has been banned inthe Great Lakes since 2005, manygroups believe the ban should be lifted,as there have been virtually no environ-mental problems to date.

Hopefully, the Deepwater Horizondisaster will stiffen the resolve of regu-lators on both sides of the border tomaintain the ban on drilling in theGreat Lakes, no matter how much oilcosts in the future.

Depending on where it occurred, ontop of any environmental damage, anoil leak in the Great Lakes could cut offdrinking water supplies for up to 40million people. Certainly the odds ofanything going wrong would be verylow. but I’ll bet that’s what BP wasthinking before April 20, 2010.

the EPA is closely watching dissolvedoxygen levels, which so far had re-mained in the normal range.

She also stated that the USCG, inconsultation with EPA, issued directivesto BP on June 29, 2010, on how thecompany should manage oil, contami-nated materials and liquid and solidwastes recovered in clean-up operationsfrom the oil spill in the affected Gulfstates. These directives create enforce-able requirements, implementation pro-cedures and oversight plans related toBP’s handling of waste materials. Thedirectives require BP to give EPA andstate agencies access to facilities, or lo-cations where waste is temporarily orpermanently stored.

So now what happens? As with past spills, the environmen-

tal, legal, political, social and economicramifications, caused by this disaster,will likely be felt for decades. Accord-ing to some reports, Prince WilliamSound in Alaska has still not fully re-covered from when the tanker ExxonValdez ran aground on March 24, 1989,and released some 260,000 to 750,000barrels of crude oil into its waters.

According to a report by the WorldResources Institute (www.wri.org), thedockside value of fish brought in fromthe Gulf of Mexico is approximately$997 million per year. Assuming thatthis value can be distributed accordingto primary production levels, eachsquare kilometre affected by the spillcan be thought of as generating $3,261in annual commercial fisheries value. Atwenty percent loss of this ecosystemservice value over a twenty year periodwould imply a present value loss in theorder of $350 million, or $875 millionif loss of value is closer to 50%.

The report also says that, from theYucatan Peninsula to Key West inFlorida, the oil spill has jeopardizedrecreation, tourism, property valuesalong the coast, and the ability ofcoastal marsh areas to sequester carbondioxide and provide storm and hurri-cane protection.

I am sure that most people are un-

The Deepwater HorizonDrilling platform explodedand sank in the Gulf of Mex-ico, on April 20, 2010, tragi-

cally killing 11 workers and setting offthe largest oil spill on record. Thanks tolive underwater video feed, the wholeworld could see the brown plume of oilblasting out of the broken well head, atrates estimated to be between 6,000 to60,000 barrels per day.

Some three months later, on July 16,BP announced that it had finally beenable to cap the 1,500 metre deep well,shutting off the flow of oil. However,only when two relief wells are finished,and the well is sealed off permanently,will the threat of further oil release beeliminated. The total amount of oil re-leased is staggering, ranging from500,000 to five million barrels of oil.

In a July 15, 2010, statement to a USSenate Appropriations Committee, En-vironmental Protection Agency admin-istrator, Lisa P. Jackson explained thatthe US Coast Guard (USGC) is the in-cident-specific chair for the gulf spilland that her agency is one of many pro-viding support. EPA’s monitoring andsampling activities provide the USCG,the Gulf states, and local governmentswith information about the potentialimpacts of the oil spill on the health ofresidents and aquatic life along theshoreline.

EPA is collecting samples for chemi-cals related to oil and dispersants in theair, water and sediment, supporting andadvising USCG on efforts to clean re-claimed oil and waste from shorelines,and closely monitoring the effects ofdispersants in the subsurface environ-ment.

On May 10, 2010, EPA and USCGissued a Directive requiring BP to im-plement a monitoring and assessmentplan for both subsurface and surfaceapplications of dispersants, which arepart of its oil spill response. For subseamonitoring, toxicity data generatedfrom monitoring to date did not indicatesignificant effects on aquatic life, ac-cording to Ms. Jackson. She added that

current labour market situation, ECOCanada’s research team designed a study toidentify and investigate critical human re-source issues facing Canadian municipalities.

The result was a report titled MunicipalWater & Waste Management Labour MarketStudy that outlines labour supply patterns andtrends. Research was carried out through sev-eral surveys and focus groups with facilitymanagers, human resources personnel, hiringmanagers, and association representatives.

Some of the issues outlined in the studyinclude: an aging workforce, shallow candi-date pools, a history high of turnover rates, alack of resource and training support, andoverall awareness.

1. An aging workforce. According to re-search, the labour force working in bothwater/wastewater and solid waste manage-ment facilities share the same key demo-graphics. Both are primarily made up of men,with women representing less than 20% ofevery occupation examined.

Focus group and National Working Groupparticipants felt the lack of female represen-tation is due to poor marketing. Thoughwomen have the skills to do the job, many arenot aware of the career possibilities. Someparticipants reflected this could also be the re-sult of a legacy of hiring managers who are bi-ased towards male candidates.

A large portion is approaching the averageage of retirement, and perhaps most alarmingis the prevalence of workers in positions crit-ical to facility operation nearing retirement.For example, in both water/wastewater treat-

Arecent report, released by theFederation of Canadian Munici-palities, has revealed that Cana-dian municipalities are reaching

a breaking point. Over the past 20 years,growing responsibilities and reduced rev-enues have caused the deficit in municipal in-frastructure to grow to approximately $120billion dollars and it will continue to grow by2 billion each year, as assets reach the end oftheir service life, and repair and replacementcosts increase.

Evidence of how this kind of declinecould affect us has become apparent over thepast few years. In 2000, following a period ofheavy rain, Walkerton, Ontario’s water wassending residents to the hospital with E.colipoisoning. Only 11 months later, the City ofNorth Battleford, Saskatchewan, experienceda drinking water outbreak of gastroenteritis,which affected some 5,800 to 7,100 peoplefrom the area.

Unfortunately, many municipalities do nothave the capacity to fund upgrades or new fa-cilities on their own, leaving it up to Infra-structure Canada to foot the bill. So far, theyhave created the Building Canada Fund to as-sist Canadian municipalities in upgrading andreplacing their existing infrastructure.

However, while this initiative securesfunding for new facilities, it does not examinethe labour market required for these facilities.To research this, Human Resources and SkillsDevelopment Canada sought out ECOCanada (Environmental Careers Organiza-tion).

Water Supply Infrastructure

Twenty year old fiberglass pipeline found to be inpristine condition

Accelerated aging tests, such asASTM D3681, Standard TestMethod for Chemical Resist-ance of Fiberglass Pipe in a

Deflected Condition, are a commonmethod employed to predict the life of anobject after a shorter period of testing.

Tests of Hobas pipe predict a lifespanof over 100 years, but how can this beverified in practice? Last year in Odessa,Texas, the recovery of a pipeline gave thecompany the opportunity to retrieve pipethat had been in service for 20 years.

In 1987, the West Texas Water SupplySystem (WTWSS), which operated nearOdessa, expanded its distribution linesusing 18-inch diameter, centrifugally-cast, fiberglass pipes. Two separate lineswere included in the project to deliverbrackish water from the Capitan Reef tonearby oil fields for use in secondary re-covery processes.

Centrifugally-cast,fiberglass-reinforcedpolymer mortar (CCFRPM) “fiberglass

pipes” were chosen because of their in-herent corrosion resistance. The brackishwater temperature is normally around 90-95 degrees F, and it is also contaminatedwith hydrogen sulfide.

The first of the two lines installed was21,000 feet long. It was completed in thefall of 1987, field tested to 185 psi with-out signs of a single leak, and put intoservice delivering 35,000 barrels per day.A second line, which included a 124,000-foot extension, was completed in early1988. Each of the lines could deliver upto 120,000 barrels per day.

Last year, Centurion Pipeline L.P. con-tacted Hobas. An adjacent gas pipelinerupture had damaged several segments ofthe existing brackish water line and theowner needed replacement pipes. Timelyrepair of this main supply line was criti-cal. Eighty feet of new 18-inch diameterCCFRPM pipe were supplied to repairthe small portion of the damaged line.

“Throughout the process, we were

lucky enough to receive some of the over20-year-old pipe back,” stated Pepe Ro-driguez, Hobas’ quality control supervi-sor. “We reviewed the files we keeponsite for all manufactured products andwere able to determine that this was oneof the first CCFRPM pipes manufacturedin the US, back in November of 1987.”

It is rare that segments of pipeline areavailable for testing as most remain inuse for their lifetime. Stork MaterialsTechnology, of Houston, was hired toevaluate the mechanical properties of thereturned CCFRPM pipe. A variety oftests were performed in accordance withthe ASTM standards for the product. Inall cases, the results exceeded the origi-nal requirements.

WTWSS management expected a50 year or longer service life for theCCFRPM pipes in this particular envi-ronment. Testing on pipe after 20 yearsconfirmed this expectation.

Testing performed in accordance with ASTM standards showed original require-ments were exceeded. Physical testing of specimens included axial tensilestrength and strain (pictured), hoop tensile strength, hoop flexural strength andstrain, and axial compressive strength.

The centrifugal castingprocess allows Hobas to

accurately control thethickness of the

pipe’s layers.

neck and a costly operation at the plant.To facilitate future upgrades at the plant,retrofit the headworks, and eliminate theintermediate pumping, the Lift Stationpumping needed to accommodate an ad-ditional 3.0 m of static head.

After improvements to the existing LiftStation over the past 10 years, a reductionin flows, and the replacement of four ofthe original pumps, the City contemplatedcontinuing with upgrades to the existingstation as opposed to constructing a newfacility at a revised cost of roughly $30million (2009 dollars). Incorporated in theapproach was the proposal to eliminatethe existing intermediate pumps by ele-vating the headworks and hydraulic gradefrom the pump station.

R.V. Anderson Associates Limited(RVA) was retained by the City to designupgrades to the Lift Station and replacethe two remaining original conventionaldry pit pumps with high efficiency drypit submersible types. By doing so, theCity will delay, likely indefinitely, theconstruction of a new lift station andheadworks. The detailed design of theseupgrades employed Computational FluidDynamic (CFD) Modeling to substanti-ate the performance of the Lift Stationpumping.

Pump upgradesThe existing Sudbury WWTP Lift

Station was constructed in 1960 with a

In 1992, a Class Environmental As-sessment was completed to evalu-ate options to service an expandingpopulation within the tributary area

of the Sudbury, Ontario, WastewaterTreatment Plant. The preferred optionwas to expand the existing plant to treatan average day flow of 102,375 m3/day, amaximum day flow of 204,750 m3/day,and a peak flow of 409,500 m3/day. It in-cluded construction of a new Lift Stationat a total cost of $17.5 million (1992 es-timate) to handle future peak wet weatherflows. Recently, the Class Environmen-tal Assessment (EA) was amended and arevised 25 year future peak wet weatherflow of 386,000 m3/day was estimated.

The Challenge: Optimize the Sudbury WWTP Lift Station

Due to the unique geological condi-tions in the Sudbury Basin, a network ofrock tunnels was constructed in the early1960s to convey sewage to the Lift Sta-tion at the Sudbury WWTP site. Ap-proximately 21 km of rock tunnel ofvarious depths terminates at the LiftStation where the sanitary sewage ispumped roughly 30 metres to the surfacefor treatment.

The Sudbury WWTP Lift Station hasexperienced a number of operational is-sues over the last 15 years, primarily re-lated to peak wet weather flows. In 1996,the Lift Station incurred a major pumpingfailure resulting from flooding in the drywell, which affected numerous nearby res-idences and left the City without waste-water treatment for an extended period oftime. Since that time, the City has re-placed four of the original conventionaldry pit pumps with two 280 hp and two525 hp Flygt dry pit submersible types.The remaining two pumps are conven-tional dry pit types, each rated at 300 hp.

On occasion, peak flows have chal-lenged the capacity of the station, causingthe rock tunnel to surcharge approxi-mately 20 m and forcing the City to by-pass untreated sewage upstream of theplant.

In addition to limitations with capac-ity, wastewater at the plant is currentlypumped after the headworks. This inter-mediate pumping is currently a bottle-

dry well/wet well configuration and aseparate screening room approximately30 m below surface. The incoming sani-tary flow from the rock tunnel is splitinto two 1.2 m x 2.1 m channels that con-vey sewage through coarse screens to thepump intakes, as shown in Figure 2. A400 mm diameter equalization line linksthe wet wells. The dry well houses sixraw sewage pumps.

In 2009, the City and RVA initiatedthe preliminary design to replace the tworemaining pumps. The preliminary de-sign reviewed the hydraulics at the LiftStation in order to answer the followingquestions:• Can the new pumping configuration

handle the projected peak flows?• Can the surcharge in the rock tunnel

be utilized in the wet well to increase pumping capacity?

• Will the existing wet well configura-tion convey adequate raw sewage to satisfy the pump require-ments? And should the smaller pumps be moved to the end of the wet well?

• Will a larger equalization pipe between the existing wet wells improve pump suction conditions?

• How will the existing suction hoods affect pump performance conditions under various flow scenarios?

• What are the risks of vortexing, pre-rotation, pump cavitation, prema-ture wear, etc?A desktop hydraulic review of the

rock tunnel was completed, utilizing as-built data and projected flows to assessthe available surcharge at the SudburyWWTP Lift Station under peak flowconditions. Although future peak wetweather flows are estimated at 386,000m3/day, the review also considered thetheoretical ultimate peak flow of 432,000m3/day as outlined during the design ofthe City’s South End Rock Tunnel.

The range of available surcharge wasdeveloped to evaluate the Lift Stationperformance based on the proposedpumping configuration in an attempt tosatisfy the 25 year peak flow as well asthe ultimate capacity of 432,000 m3/day.The static profile of the rock tunnel per-mits approximately 18.9 m of surcharge,prior to affecting sanitary service; how-ever, the desktop analysis indicated thatup to 5 m of surcharge is available at theLift Station under peak flow scenarios.

The Lift Station can theoretically ac-commodate the future peak flow of386,000 m3/day under 4 m of surchargewith the largest pump out of service,satisfying MOE design guidelines. Fur-thermore, under minimal surchargedconditions, it was determined the stationcould accommodate the ultimate peak

flow with all six pumps in service.Theoretically, the design of the pump-

ing upgrades indicated that the Lift Sta-tion could accommodate the peak flowsand proposed elevated headworks; how-ever, the City and RVA had numerousquestions regarding the performance ofthe wet well and pumps under these op-erating conditions. This ultimately led toa CFD modeling exercise on the pro-posed pumping configuration.

Computational Fluid Dynamic modeling

The CFD modeling was done by ITTWater and Wastewater in order to:• Review pumping performance and

operation of the pumps with the addition of the proposed configuration under peak flows and surcharged conditions.

• Optimize pump layout including suction/discharge piping.

• Gauge wet well performance including flow limitations, potential cavitation, vortexing, or any negative effect that may affect the performance of the pumping configuration.

• Provide recommendations to improve hydraulic efficiency of the pumping configuration.

The modeling assignment included: • Constructing a three-dimensional

computer model based on as-built information and proposed pumping continued overleaf...

configuration including wet well dimensions, pump data, and inlet and suction conditions provided by RVA.

• Using computational fluid dynamic CFD++ unified grid modeling program to simulate flow scenarios. (CFD++ provided by Metacomp Technologies, California)

• Modeling at least five base pumping sequences to determine worst-case scenario(s).

• Reviewing results of base runs and recommend modifications and efficiencies.

• Modeling at least two optimization pumping sequences based on results of base runs incorporating recom-mendations.

• Providing results of optimization and final recommendations for hydraulic efficiencies, including modifying the equalization line and moving pump locations.The evaluation criteria to interpret the

CFD results were adapted from TheAmerican National Standard for PumpIntake Design (ANSI/HI 9.8-1998) andThe Hydraulic Institute Standards whichgenerally included:1) Velocity Distribution at the Pump

Inlet – where deviations from the mean should be no less than 10%.

2) Swirl Angle at the Pump Inlet – where

3) Vortices – which must be avoided near pump inlets.

4) Temporary Variations of Flow –where fluctuations of velocity at any

ration due to the characteristics of the in-coming sanitary flow and did not formpart of the modeling exercise.

Base simulations were carried out,and their results evaluated at the impellerplane for each pump. Each simulationidentified similar behaviour noted as sig-nificant swirling, and both wet wells hadsimilar results. The swirling effect wasattributed to the abrupt flow transitionfrom the rock tunnel inlet to the wet wellwhich caused reverse flow circulation,where the flow near the top of the wetwell reverses direction prior to enteringthe suction hoods. Figure 3 shows flowpaths at pump 2B during a peak flowsimulation.

In order to reduce the high swirl an-gles in the suction piping, guide vaneswere proposed inside each of the exist-ing suction hoods. Subsequent flow sim-ulations determined that swirling wasreduced to an acceptable level.

Vortices were not evident, providedthe liquid level was maintained at an ap-propriate level and the suction hoods re-mained intact.

CFD modeling did identify that, due

to relatively low velocities at the end ofthe wet well, the wet wells may be proneto inducing sedimentation. The risk ofsedimentation may be reduced by exer-cising the pumps furthest from the intakeat full capacity on a regular basis as ameans of flushing the wet wells. Further-more, since the maximum liquid leveldifference between the wet wells underthe different flow scenarios was negligi-ble, the equalization line had no impact

on the flow distribution in the wet well. Summary

Investment in a CFD modeling studyhas helped to optimize the pump capac-ity of the existing Sudbury WWTP LiftStation, and the recommendations de-rived from the modeling were incorpo-rated into the detailed design of the LiftStation pumping upgrades. This has al-lowed the City to achieve a number ofbenefits, including:

1. Use of existing infrastructure to handle the projected peak wet weather flows.

2. Deferred construction of a new lift station at a total cost of $30 million.

3. Reduced capital construction cost by maintaining existing pumping con-figuration.

4. Removal of the intermediate pumping station at the plant, which representssignificant operational and main-tenance savings.

5. Recognition of the need to aggressively reduce inflow and infiltration, as well as peak flows.The detailed design of the Lift Station

upgrades was completed in March 2010.Construction is expected to be completeby December 2010 for an estimated costof $5 million.

The swirling effect was attributed to the abrupt flow transition from the rock tunnel inlet

to the wet well which caused reverse flow circulation, where the flow near the top of

the wet well reverses direction prior to entering the suction hoods.

Meeting these challenges, the customwinch system provided a narrow drumconfiguration for easier mounting on thelimited deck space.

Designed to be a model “FloridaYard,” the landscape demonstrates theuse of native and drought-tolerant plants,xeriscaping, rainwater catchment, pervi-ous walkways, and other ways to reducedetrimental runoff into Florida’s estuar-ies and bays.

This project showcases ways to con-serve resources, learn about energy effi-ciency, understand water conservation,use the least toxic building materials andrecycled products, and reduce runoff.

The philosophy of a “green” buildingis a minimalist approach to the environ-mental impact that any new development,in this case, the school, has on nature. Agood example of green building is the de-velopment of rainwater harvesting sys-tems. A well-engineered system providesfor reduced flood occurrence, erosion

the points needed for Leadership in En-ergy and Environmental Design (LEED)Silver status at the new school.

The rainwater harvesting system usesrainfall that would otherwise be collectedas surface runoff and channeled throughthe municipal stormwater system to dis-charge. The “free” rainwater will insteadbe stored in a cistern and used for flush-ing low-flow toilets and landscape irriga-tion, eliminating the need for expensive,municipally-treated fresh water.

The critical framework of the rain-water collection system consists of: • a cistern to collect water, • transfer pumps to convey the stored

water to the building, • a particulate filtration system to

remove sand and grit, and • a disinfection system to kill harmful

bacteria and contaminants that may be present in the water.

How the system worksThe cistern at the new college is a

20,000-gallon Highland Tank HighDRO®

protected, steel underground rainwatercollection tank (RCT). Steel was the nat-ural material of choice for the tank be-cause of its LEED “point scoring” highrecycled content and high reclamationrate. Other user benefits that influencedthe choice included the compatibility ofmaterials, inherent strength of the tank towithstand over four feet of overburdenand, most importantly, the long-term se-curity of the stored water.

Features of the RCT include an inletdiffusion baffle, SSPC-SP-10 grit blastand NSF compliant polyurethane inter-nal coating, heavy-duty 100% solidspolyurethane external coating, overflowwith trash skimmer, easy access man-ways, and a duplex pump package.

The pumps utilize floating suctions toconvey clean water to the building. Aspecial level sensor was designed to con-trol and monitor the water levels in theRCT and send a continuous signal to thebuilding management system.

Particulate filtration is the first line ofdefence against contamination in a rain-water collection treatment train. The fil-tration system basically consists of a

Energy Conservation

In 2005 alone, Canadian industrysaved $3.9 billion in energy costs. Ac-companied by reducing energy usage,power quality issues such as power sags,swells, transients, harmonics, etc., can beaddressed and rectified, as it is estimatedthat 30% of all business downtime is re-lated to a power quality issue of somesort.

Here are a few steps to help youbegin:• Ensure top management commitment.• Establish an energy committee with

employee members.• Assign responsibilities.• Prepare an energy file to track

progress.• Measure base load energy.• Monitor energy usage to quantify

results and savings.The best way to give an accurate in-

dication of how and where you are using

Reducing electricity costs willboost your bottom line. Thisisn’t news, it’s something youknow and have heard before.

But there are various ways to accomplishthis goal; so, where do you begin?

Unless you have the data, you cannotmanage your energy costs effectively. Ina recent survey conducted on “best-in-class” companies, it was noted that, withan energy management program, theywere able to reduce their energy con-sumption by 15% year after year andhave an overall equipment effectivenessof 90%.

Starting an energy management pro-gram within your facility is the easiestand most effective way to decrease yourenergy usage and increase overall effi-ciency.

Since 1990, energy efficiency in theindustrial sector has improved by 13%.

energy within your facility is throughsub-metering. This method also providesthe information needed to begin and sus-tain an energy management program.

Sub-meters can be installed in differ-ent departments to determine areas ofexcessive energy use, even down to indi-vidual pieces of equipment to determineefficiency before and after an upgrade.

Energy costs are increasing everyyear, and surveys indicate that at least30% of industry’s overall energy savingspotential can be obtained without capitalexpense, by simply making changes toprocedures and behaviour. Remember,you cannot save it unless you track it!

Floating islands are environmentallyfriendly, natural treatment systems aimed

Floating islands are constructedwetland systems in which ma-crophytes (woody plants) andgrasses are planted on an artifi-

cial buoyant matrix surface that is porousenough to allow roots to penetrate thematrix into the water column.

The floating island system is based ona similar concept to that of constructedwetland rock reed filters for wastewatertreatment, consisting of basins of rockswith plants inserted at the surface, withtheir roots extending into the water col-

at removing nitrogen and phosphorusspecies, primarily through the root zonearea (which develops below the waterline), the microbes (which populate thisarea and island matrix), and the synergis-tic interactions between the plant rhizomesand microbes. Further, the vegetationhelps to cool the surface of the water col-umn and block sunlight, which helps tocontrol algae; the vegetation gives off oxy-gen during daylight and CO2 at night.

Uptake of the nutrients by the roots/bacteria is a removal of the nitrogen andnot a conversion process such as nitrifi-cation. Therefore, once the plants uptakethe nitrogen, it is completely fixed fromthe water column and no longer availableas a pollutant.

Wiconisco Township, in Pennsylvania,owns and operates a 0.125 million-gallon-per-day (MGD) secondary wastewatertreatment plant (WWTP) which has twolagoons, which can be operated in seriesor in parallel. Each lagoon (total volume1.8 MG) is divided into two sections witha baffle. The inlet section is completelyaerated and the second section is partiallyaerated, resulting in facultative conditions.

The facultative section of the lagoonsalso serves as the biosolids storage area.Brinjac Engineering Inc. assisted theWiconisco Township with obtaining aGrowing Greener Innovative WastewaterTreatment Grant Award for $65,000 toinstall floating islands for tertiary nutri-ent removal at the treatment plant. TheWiconisco treatment plant is the Betatest site for this kind of floating islandsystem application in wastewater treat-ment.

In November 2006, Wiconisco WWTPinstalled three BioHaven floating islandwetlands units (each approximately 250sq ft) in Lagoon #2. These were providedby Floating Island International (FII). Asdescribed by FII, the BioHaven floatingisland is an advanced form of floatingtreatment wetland that “bio-mimics” nat-ural floating wetland systems invented bynature. Vegetated with native plants(preferably perennials), it is a natural andsustainable eco-system that providesmany benefits, from habitat restoration towater cleansing.

BioHaven floating islands are buoy-ant mats, planted like a garden andlaunched onto a waterway. They aremade from a matrix of fibres that lookslike a pot-scrub or loofah. The matrix iswater filtration material made from100% recycled plastic (PET), from drinkbottles, which use the most inert plasticavailable. Layers of matrix are bondedtogether with foam, which also providesbuoyancy.

help of a splitter box; hence the influenthydraulic and organic loadings to both thelagoons were considered to be similar.Realizing that the influent parameters re-mained the same, a comparison was per-formed for the effluent data obtainedduring sampling for both the lagoons.

The only difference between them is

the floating islands installed in Lagoon#2. Analysis focused on an operationaldata comparison between November2006 and January 2009 (i.e., after systemupgrades) with Lagoon #1 being the con-trol system and Lagoon #2 the upgradedsystem.

Also, since the Wiconisco wastewater

treatment plant was upgraded with a solarcirculation system in March 2009, thefloating islands system comparison datawas limited to January 2009. Operationaldata was compared for effluent BOD,total nitrogen (TN) and total phosphorus(TP). (Figures 1, 2 and 3)

As Figure 1 indicates, no significant

trend was observed for effluent BODconcentrations for the lagoons, althougheffluent BOD concentration in Lagoon#2 was observed to be lower than that forLagoon #1 after September 2007 (10months after island installation).

Overall, the average effluent BODconcentration for the lagoons remained at22.0 mg/l each between November 2006and January 2009. Effluent data in Fig-ure 2 indicates that, with all three float-ing island systems becoming operationalin November 2006, the upgraded systemshowed improvements in total nitrogenremoval.

The average effluent TN concentrationfor Lagoon #1 between November 2006and January 2009 was 22.5 mg/l, whereasit was 20.8 mg/l for Lagoon #2. Corre-spondingly, with the annual average dailyflow of 0.06 MGD for this period (fromTable 1), an equivalent 0.85 lbs TN/dayor 310 lbs TN/year reduction was esti-mated in treated effluent.

Effluent data in Figure 3 shows that be-tween November 2006 and January 2009,total phosphorus concentrations from La-goons #1 and #2 remained in a similarrange, with no significant trend for im-

provements in TP with floating island up-grades. Average effluent TP concentrationfor Lagoon #1 between November 2006and January 2009 was 5.7 mg/l, whereas itwas 5.9 mg/l for Lagoon # 2.

Improvements in BOD and TN con-centrations during the later part of thetreatment plant operations were consid-ered to be due to the vegetation growthon the islands and root developmentbelow them. The three floating islands in-stalled in only Lagoon #2 occupied only2-4% of the total surface area.

Installation of additional floating is-lands would potentially increase the veg-etation and roots surface area availablefor nitrogen and phosphorus removal andwould further improve nutrient removal.

Applied science of wastewater management

Applied science is the process of tak-ing the science and applying it to specificapplications. Thinking “outside the box”is necessary for applied science in re-mote communities in response to thechallenges of extreme cold, very limitedaccess, extraordinary costs, and scant re-sources. These are a few of the routinechallenges that engineers, suppliers andcontractors must face in designing andconstructing wastewater treatment facil-ities for remote areas.

The applied science, or engineering,of wastewater systems in remote com-munities should follow the key principleof appropriate technology. This principlehas been applied inconsistently to pro-jects in remote communities, and, conse-quently, a significant number of projectsare not meeting the performance expec-tations of the communities, or the regu-latory authorities.

Appropriate technology suggests that,whatever process is being applied forwastewater treatment, it must considerthe biophysical context of the projectsite, which includes location, climate,landforms, and possibly the native vege-tation. Cold weather and distance are thetwo major factors in the consideration ofappropriate technology. Although engi-

The remote areas of Canadaconstitute as much as 45% ofthe country’s land mass, includ-ing the regions of the Yukon,

Northwest Territories, Nunavut, Nunavik(northern Quebec), and Nunatsiavut(northern Labrador). This vast region ispopulated by a mere 100,000 people oc-cupying 90 communities, for an averagepopulation of 1,100 per community.

In fact, the communities of White-horse (24,000), Yellowknife (19,000) andIqaluit (7,000) account for about half ofthe population, making the average pop-ulation, more realistically, fewer than 600people per community.

Developing and sustaining infrastruc-ture in remote communities has alwaysbeen influenced by a variety of technical,financial, administrative, operational,and regulatory factors. Over the pastdecade, the complexity of these factorshas increased substantially, with changesto available financial resources, admin-istrative structures, operational responsi-bilities, and regulatory environments.

Many of these changes have increasedthe overall complexity of infrastructuredevelopment and sustainability in remotecommunities, particularly at the commu-nity level. Many communities are find-ing the demands of these complexities tobe well beyond their financial and ad-ministrative resources, and, as a conse-quence, are placing themselves in veryundesirable situations with regard tocommunity funding and regulatory com-pliance.

The challenges associated with waste-water management in remote communi-ties occur in the areas of science, appliedscience and social science.

Science of wastewater managementThe science of modern wastewater

treatment systems can be described by anumber of unit processes, each of whichprovides an increasingly higher quality ofsewage effluent by applying various phys-ical, chemical and biological actions. Theunit processes include preliminary treat-ment, primary treatment, secondary treat-ment, tertiary treatment, disinfection, andresiduals management.

neering designs may take into accountmeasures to prevent wastewater facilitiesfrom freezing, it is also prudent to designthe means to thaw a facility in the eventit does freeze. In fact, it may be appro-priate to say that it is not a matter of ifthe facility freezes, but when it freezes.

Remote communities, by definition,are located at a great distance from whatwould be considered the “normal” ameni-ties available to a community. Conse-quently, the resources available for routineoperation and maintenance may not beavailable at the facility site, and mobiliz-ing them may be not be possible for days,or more, and may cost extraordinaryamounts of money.

Appropriate technology for wastewatertreatment in remote locations can makeuse of the extensive cold. One example isthe concentration of sewage biosolidsthrough the freeze-thaw process, and sub-sequent composting through the limitedsummer months. This process is just be-ginning to be applied in the community ofIqaluit, Nunavut.

Social science of wastewater management

Although the science and applied sci-ence of wastewater treatment need moreattention, at least some work has beendone on these factors over the past sev-eral decades. In contrast, the social sci-

ence of wastewater management in re-mote communities has been virtually ig-nored. Even the term “social science”may not be all-encompassing enough toapply to “all the other stuff” associatedwith wastewater management in remotecommunities, but it is a start.

Social science associated with waste-water management in remote communi-ties presents a multitude of challenges,including administrative, financial, andhuman resources issues. Any remotecommunity, regardless of size, has theneed for a fully funded, fully staffed andfully trained community administration,but this is seldom seen.

Administrative challenges includemultiple levels of government, limitedresources and changing rules. There maybe several levels of local governmentrepresenting the aboriginal community,as well as the non-aboriginal community,plus the territorial government, and landclaims by the aboriginal community. Thefederal government may have several de-partments working independently to rep-resent their own mandates. In somecommunities, there may be six or morelevels of government.

The devolution of responsibilities hascontinued for several decades in responseto demands for autonomy from somecommunities, as well as the downsizingof territorial governments. This devolu-tion process has had varying degrees ofsuccess. For instance, the latest chapter in

the Northwest Territories is the so-called“New Deal”, which was implemented in2007 and provides block funding to allcommunities. Some communities areseizing the opportunity, while others areoverwhelmed. In spite of the best-con-

ceived and comprehensive introduction possible, the NewDeal will fail in some communities.

Financial challenges include financial management,capital funding, and operation and maintenance funding.Financial management is a challenge for any community,and represents a continuing challenge for many remotecommunities. Every remote community has a communitybudget that is proportionately larger than would normallybe expected in a southern context. Management of thisbudget requires skill and training that many communitiesdo not possess.

Funds from senior governments for capital, operationsand maintenance have diminished significantly over thepast decade, and communities are being encouraged to bemore self-sufficient financially.

Human resources issues may be the most challengingaspect of the social science of wastewater management.People represent a very dynamic environment that hasbeen plagued with a chronic lack of resources for hiring,training, and retaining.

New technologiesLagoons have been the sewage treatment process of

choice for most remote communities, because of theircost-effectiveness and simplicity of operation, and theabundance of space that is available to most communities.This situation has been changing over the past decade asregulators have lobbied water boards and pressured com-munities to improve effluent quality by applying conven-tional “southern” mechanical technologies.

This evolution has had mixed results, with new me-chanical systems operating in the northern communitiesof Fort Simpson, Rankin Inlet, Iqaluit and Pangnirtung.Although it may be said that these systems are generallyoperating in compliance with the water licence parame-ters, the communities are faced with sustaining theseprocesses with limited financial and human resources.

New challenges are emerging because of demands formanaging the significant biosolids waste stream producedby these waste treatment processes.

The ecosystems of the remote regions of Canada areunique and fragile, and must be protected; therefore,wastewater treatment is needed. Public health must alsobe protected, and wastewater treatment must serve thispurpose as well. To date, however, the protective meas-ures for these ecosystems and public health have not beendeveloped, or implemented, based on the necessary sci-ence, applied science and social science information.

ulations will cover all possible disinfec-tants, including chlorine gas, calciumhypochlorite, sodium hypochlorite, on-site generation, ultraviolet light, ozone,and others.

In addition, fire code regulationsmust be considered. There has beensome consolidation of the codes so thereare only two in current use. They are theinternational code (a consolidation of thestandard code and national code) and theNFPA 1 (National Fire Protection Asso-ciation), formerly known as the uniformcode. In addition, The Ten State Stan-dards, written specifically for the waterand wastewater industries, are still em-ployed in aiding the design of water andwastewater plants.

New security regulations will soonbe in force for water and wastewatertreatment plants. The US House of Rep-resentatives passed the Chemical Waterand Security Act in November 2009, call-ing for the EPA to establish security pro-grams for water and wastewater plants.

In the case of water treatment plants,the first criterion to be used is the size ofthe population served. Then, the facility

is to be classified into a Tier system (Tier1, 2, 3 or 4) that can be used to establishthe security hazard. These new securityregulations will deal with the design anduse of the facility, with the primary pur-pose of protecting it from attack by indi-viduals such as terrorists.

Although details are yet to be final-ized, it is anticipated that the plantboundaries must be protected from en-croachment, gates monitored, and mate-rials used in the treatment of the waterand wastewater protected during deliv-

ery, receipt, storage, and use. Of primaryinterest are the toxic and hazardouschemicals (chlorine, sulfur dioxide, am-monia) used in these facilities, their con-tainment, and the prevention of theirrelease to the surroundings, both insideand outside the plant boundaries.

Containment of the hazardous chem-icals can be provided by a scrubbing sys-tem. Such systems are capital-intensiveand may require frequent servicing andperiodic operation to ensure that the en-tire system is operational.

Another containment system is Halo-gen Valve Systems automatic valve op-erator (AVO). These are much simplerthan scrubbing systems and automati-cally close any open valve on the com-pressed cylinders or containers in use.They can be activated with electricalcontacts created by fire alarms, gas leakdetectors, seismic devices, or remoteelectrical control systems like SCADA.

The plant operator can activate themwith a panic button located outside thestorage and use room or in the controlroom. Up to six cylinders or containerscan be activated with one control system.The system provides an electrical contactafter the closing and torquing of allcylinder and container valves.

Each AVO is electrically operated andis mounted directly on the container orcylinder valve stem. It is battery-poweredand operable even during a power failure.

Halogen AVOs are designed forelectromechanical valve closure only.Manual opening of the valve by the oper-ator is the only recommended safety pro-cedure after the valve has been closed.This requires visiting the site, examiningthe cause of the valve closure and cor-recting the cause, before the system isrestarted. The Chlorine Institute has rec-ognized the advantage of these emergencyshutoff systems for chlorine gas and hasincluded their use in guidelines for cylin-der and ton container valve operation.

Anywhere compressed toxic or haz-ardous gases are used in a process appli-cation, there is a need to consider thesafety and security of the containers instorage and use.

Transport trucks were added to theprogram at international border crossings.

The program is undertaken during thepeak tourist season (Victoria Day toThanksgiving). It focuses on educatingdrivers. Activities include erecting signs,distributing brochures at tourist parkingareas and border crossings, surveyingmotor coach and transport truck driversabout vehicle idling habits, as well asspeaking directly to drivers to educatethem about the benefits of reducing un-necessary vehicle idling.

Monitoring In addition to driver education, the pro-

gram also includes compliance monitor-ing. Monitoring allows for improvementsto the program, including increasing focuson “priority sites” and targeting specificproblem drivers and/or companies. Aver-age idling times and compliance rates arecalculated.

To be completely compliant, motorcoach and transport truck drivers must

Initiatives to reduce greenhouse gas(GHG) emissions are being imple-mented by communities acrossCanada. One of the focuses of these

programs is the elimination of unneces-sary vehicle idling.

On average, a diesel vehicle idling at1,000 revolutions per minute will con-sume approximately four litres of fuel perhour. For every litre of fuel consumed,about 2.8 kilograms of GHGs are re-leased. An idling diesel-powered vehiclecan release up to 11.2 kilograms of GHGsper hour, including carbon dioxide, nitro-gen oxide and carbon monoxide, as wellas volatile inorganic compounds and par-ticulate matter.

The Niagara Parks Commission(NPC) was established in 1885 to act assteward for important and sensitive parklands in the vicinity of the Niagara Falls.Over 10 million people visit these areaseach year.

The NPC’s experience is that compli-ance with its policies and regulations isbest accomplished through partnerships,cooperation and education. The ‘Sparethe Air’ Emissions Reduction Programwas developed in 2001 to focus on the re-duction of unnecessary idling of themore than 40,000 motor coaches thatbring visitors to Niagara Falls and Niag-

turn off their engines within 30 secondsof arriving at a site and are allowed to idlefor up to one minute before leaving.When a motor coach is loading or un-loading passengers, an extra three min-utes is allotted at arrival and departure.

The program is based on voluntarycompliance; no fines or penalties aregiven to drivers who are not in compli-ance with program measures.

Driver responsesSurveys are conducted to understand

the reasons that drivers may idle their ve-hicles excessively. The most commonreasons for idling, as cited by motorcoach and transport truck drivers, areoutlined in Table 1.

Through the driver survey process, itis apparent that companies are becomingmore aware of the environmental andeconomic benefits of reducing unneces-sary idling. Some companies surveyedhave implemented formal policies to re-duce idling, and many others are moni-toring the idling times of their vehicles,have installed automatic shut-off devices,are educating drivers about the effects ofidling, and offer incentives to reduceidling such as bonuses and intracompanyrecognition.

Driver surveys also provide insightinto the level of awareness of the pro-

gram. In 2009, over 400 motor coach andtransport truck drivers were surveyed.Based on these surveys, close to 70 per-cent of the motor coach drivers who vis-ited the Niagara River Corridor in 2009were aware of the Spare the Air Program,while 30 percent of the transport truckdrivers at the two border crossings hadknowledge of the program. Lower aware-ness by transport truck drivers is ex-pected due to the greater number oftransport trucks and the less frequent na-ture of their trips.

Information from the surveys assistsin future facility planning, such as creat-ing more shaded areas so buses staycooler in the summer, or establishing orbetter equipping lounges so that driversdo not have to wait in their vehicleswhile their passengers visit the area.

Idle-Free ToolkitThe success of NPC’s Spare the Air

Program led Motor Coach Canada andNatural Resources Canada (NRCan) todevelop an Idling Reduction Toolkit,which was completed in 2007, and isavailable to motor coach companies, andtourist destination operators acrossCanada. The toolkit also includes pro-

grams and information to reduce trans-port truck idling at Canada-US bordercrossings.

The toolkit was developed by Urban& Environmental Management Inc., inconsultation with over 100 stakeholdersacross Canada. It contains a step-by-stepguide for implementing a successfulidling reduction program and providesexample materials such as signage,posters, and brochures. The toolkit alsocontains information on program sched-uling and budgeting, how to develop part-

nerships with municipalities and local or-ganizations, and provides instructionalmaterial on developing and implement-ing idling control by-laws. It is availableonline at fleetsmart.nrcan.gc.ca/idling-re-duction-toolkit.

over the full span of measurement. Thesedevices typically are used for processcontrol as well as inventory control andmanagement.

The technologies used to measurelevel are affected differently by the vary-ing process conditions. A brief descrip-tion of each of the different technologiescommonly used in a wastewater facilityfollows:• RF Admittance employs a radio fre-quency signal. A change in RF admittanceindicates either the presence or absence ofmaterial or how much material is in con-tact with the sensor, making it highly ver-satile and a good choice for a wide rangeof conditions and materials for point orcontinuous level measurement.• Radar uses frequency modulatedcontinuous wave (FMCW) through-airtransmission that allows for accurate non-contact reading of reflected electromag-netic signals.• Magnetostrictive uses an electric pulse

Engineers should have a thor-ough understanding of avail-able technologies, whether theyare selecting instrumentation

for level, open channel flow, or sludgeblanket monitoring in new or retrofit in-stallations.

No single technology is appropriatefor all level measurement challenges be-cause of the variety of applications andoperational differences in the processes.Regardless of application, there are twomajor classifications of level measure-ment instrumentation: point level andcontinuous level measurement.

Point level (On/Off) measurement in-dicates the absence or presence of thelevel at a certain threshold (point) withina vessel. Point level switches are used ashigh level and spill prevention alarms,low level and pump protection alarms,and to turn pumps on and off.

Continuous level (Proportional) meas-urement indicates the level in a vessel

from ferro-magnetic wire to accuratelydetect the position of a float with em-bedded magnets. As the pulse intersectsthe magnetic field from the float, a sec-ond pulse is reflected back to an electriccircuit that accurately reads the level.• Conductivity Switch measures the dropin resistance that occurs when a conduc-tive liquid is brought into contact withtwo probes or a probe and a vessel wall.• Ultrasonic (Point Level) measurementelectronically resonates a crystal at fixedfrequency to generate sound waves thattravel across an air gap to a second crys-tal. As liquid fills the gap between thetwo crystals, the second crystal begins toresonate with the first.• Ultrasonic (Continuous Level) meas-urement uses a transmitter to generate anultrasonic pulse and measures the time ittakes for a reflected signal to return tothe transducer to determine the level of aliquid.• Time Domain Reflectometry (TDR)

takes a highly focused electronic wave, guided by a metallic rodor flexible cable, to the surface of a liquid and reflects it backalong the rod or cable to determine the level.• Hydrostatic Pressure immerses a two-wire transmitter with asensing diaphragm and a sealed electronic circuitry that transmitsan analog signal proportional to the liquid level above the sensor.• Float Switch relies on a low-density float mounted in a vesselthat is magnetically coupled to a limit switch.• Vibration/Tuning Fork is piezoelectrically energized and vi-brates at a frequency of approximately 1200 Hz. When the forkis covered in material, the frequency shifts. The frequency shiftis detected by the internal oscillator and converted into a switch-ing command.

Point level solutionsAdvanced RF point level devices are the most versatile of the

point level switches. They provide excellent spill/overfill pro-tection, are simple to install, and have no moving parts, makingthem virtually maintenance free. Their robust design and cir-cuitry that ignores coatings, make them an ideal solution formany wastewater applications.

Both tuning forks and ultrasonic gap switches provide reli-able high or low-level measurement in a wide variety of liquids.

For non-coating conductive liquids, conductivity switchesprovide economically priced measurement, while float switchescan be used in many basic applications at cost-effective prices.

Continuous level solutionsMechanical systems such as floats and bubblers require ex-

tensive maintenance and are less reliable and accurate than elec-tronic systems. Hydrostatic systems afford greater reliability, aresimple to use and are able to transmit data to another receiverfor remote monitoring, recording, and control.

RF Admittance technology is the best available for level in-dication and control. It inherently provides the greatest accuracyand repeatability in interface measurements. Variations in themakeup of upper and lower phases of a liquid have no apprecia-ble effect on system accuracy. Recalibration is not required.

For short span measurements, RF Admittance technology pro-vides the best measurements, particularly as the level of meas-urement span decreases. In spans of only a few centimetres, RFsystems can repeatedly produce accuracies of 0.8 mm.

Non metallic tanks do not pose technical problems for Ultra-sonic, Magnetostrictive, Hydrostatic Pressure, Radar and TDRtechnologies. The TDR approach is suitable for vessels with in-ternal obstructions and uses lower energy levels than airborneradar technologies. Non-contact technologies, such as radar andultrasonic, can have measurement ranges up to 40 metres.

For long-range measurements or headroom limitations, flex-ible sensors offer insertion lengths up to several hundred feet forHydrostatic Pressure and RF Admittance products. Loop-pow-ered TDR-based products allow measurement ranges up to 35metres in selected applications.

Magnetostrictive technology allows accuracy of 0.1% ofmeasurement span in flexible sensor designs up to a maximumrange of 12 metres.

Using a data acquisition networkby Stevens Water MonitoringSystems, Environ InternationalCorporation (ENVIRON) is

developing new methods to bioremediatecontaminated soils.

All organisms need food, which pro-vides energy and nutrients. Food firstneeds to be metabolized so that it can beconverted to energy and materials for cellgrowth. When an organism digests food, itchemically takes the food apart one mole-cule at a time by breaking and makingchemical bonds.

When a chemical bond is broken, theorganism needs to get rid of extra elec-trons. Organisms get rid of the extra elec-trons using electron acceptors. Chemicalremoval of these extra electrons is doneduring respiration, or breathing. Thereare two types of respiration: aerobic andanaerobic. Aerobic biochemical reac-tions use oxygen as an electron acceptor,and anaerobic organisms use other com-

rinated solvents.ENVIRON is treating chlorinated

pesticides both anaerobically and aero-bically, using an innovative new ap-proach. Dichlorodiphenyltrichloroethane(DDT) and other chlorinated compoundsare lethal to pests because they shutdown an organism’s nervous system.

Generally, aerobic bacteria will not de-compose chlorinated compounds. One ofthe methods ENVIRON is using todecompose the DDT is called CVSR(Controlled Vadose-Zone Saturation Re-mediation). CVSR employs anaerobic mi-croorganisms, which do not requireoxygen and in fact thrive in an oxygen de-ficient environment.

In order to maintain anaerobic condi-tions in the CVSR areas, the soil is irri-gated to, or near, saturation (40 to 50%).The CVSR areas are also dosed with alactate electron donor/energy sourceprior to irrigation to promote microor-ganism growth. While the upper con-taminated soil needs to stay at or nearsaturation, it is important that soil mois-ture levels below the treatment areas staybelow the field capacity (25 to 30%) toprevent toxins from leaching downward,contaminating the underlying aquifer.

Data from the Stevens Hydra Probehelps ensure that the soil moisture levelsat the various depths stay at the optimalmoisture level, allowing the anaerobicmicroorganism community to thrive,while preventing the downward leaching.

ENVIRON’s research involves usingWRF to decompose pesticides under aer-obic conditions in biopiles. Soil moisturein the biopiles is maintained at a constant30%. In addition to maintaining the soilmoisture at 30%, biopiles are also aer-ated with blowers.

ENVIRON is operating a total ofnine stations, with two or three HydraProbe sensors in each station. Five of thestations are aerobic biopiles containingthe WRF, and four of the stations areanaerobic CVSR. Hydra Probes are con-figured to be digital RS485 half duplex.The first RS485 bus reaches four CVSRstations consisting of 14 Hydra Probes.

The second RS485 bus contains 10Hydra Probes in the aerobic biopiles(two probes per pile) and is connectedwirelessly to the first bus using 900 MHzSpread Spectrum Technology. The Mas-ter Radio, as well as the RS485 bus, areconnected to a cell modem.

nance and improvements in the dewater-ing and incineration processes.

Under the original operation strategy,the sequence was set to start based on theinterval time set-point from the SCADAcontrol system. Once the interval timehad elapsed, each enabled valve dis-charging the clarifier would stay open forthe duration time in seconds entered onthe SCADA system. The original control

The City of London, Ontario,operates six wastewater treat-ment plants, with a combinedaverage daily flow of approxi-

mately 210,000 cubic metres. Primaryand secondary sludge from all plants isdewatered at the Greenway plant usingbelt filter presses, prior to incineration ina fluidized bed incinerator. Phosphorusremoval is achieved through chemicaladdition, and final effluent receives sea-sonal disinfection using ultraviolet light,before release into the Thames River.

At the Greenway plant, primary sludgepumping frequencies and durations havetraditionally been controlled through setpoints entered into the SCADA system.This control system, while simple, did notadjust for variability in sludge concentra-tions during cycles, or between individualsumps.

In an effort to control the volume andconcentration of solids removed from theprimary clarifiers, two Metso KajaaniTSsolid state, non-intrusive, total solids me-ters were installed for each of the twopumping groups. Online sludge densitymeasurement helped optimize sludgewithdrawal rates and reduced sludge ac-cumulation in the primaries. This led to areduction in primary clarifier mainte-

system was maintained for two weeksafter the meters were connected andlogged information into the SCADA sys-tem. This provided a baseline for thevariation in sludge concentration neces-sary to automate the process.

For example, with interval time set to90 minutes and duration set at 3 minutes,the pumping sequence would occur every90 minutes and each enabled valve wouldstay open for 3 minutes, then the SCADAwould move on to the next dischargevalve sequence. This process would re-peat every 90 minutes.

Under the new system, new operatorset-points have been programmed in theSCADA application, such as solids den-sity (concentration) set-point, SDM skiptime and maximum duration per sump.

In the new sequence, the operator en-ters an interval time in minutes. Once thistime has elapsed, the first primary clari-fier discharge valve will open, and, oncethe valve position is open, the pump willstart. The operator also enters SDM skiptime valve indexing (seconds); duringthis time the solids density (concentra-tion) measurement is ignored to allow forthe line to charge with representativesludge from the respective tank. Whenthis delay period elapses, the solids den-sity (concentration) measurement is com-pared with the operator-entered set-point.

When the solids density (concentra-tion) process variable is less than, orequal to, the set point, the valve is trig-gered to close and the next enabled valvewill be triggered to open. Once the valveopen status is verified, the delay betweenvalve indexing will start. When the delayhas elapsed, the solids density measure-ment will be used to trigger the next en-abled valve to open. This will be repeateduntil all enabled valves have cycled. Amaximum time safeguard is also enteredin the SCADA system that limits thepump time per sump. (See Figure 1)

With the success of the installationsat Greenway, the same strategy has beenimplemented at all of the City’s waste-water treatment plants.

Value of online instrumentationThere are some observations that

would be very difficult to understandwithout online instrumentation.

Figure 2 shows the primary sludgepumping before the addition of a sludgeflow meter and density meter. It offersvery little insight other than the durationthe pump was running and the duration

each sump was open. The only approachis to continually monitor the blanket leveland guess at how long each sump shouldbe pumped. Continuous monitoring is adifficult task, and plant operators havemany other things to take care of.

Figure 3, with the addition of the in-strumentation, tells a more comprehen-sive story. We can see sludge densitypeaks of 10%, meaning the last fewsumps are pumping longer with highersludge densities, and the pump is work-ing hard to pump the high density. Thelast sumps in the cycle are getting moreof the solids because the flow and solidsbalancing across the eight clarifiers arenot equal. The trend line can be used toadjust the flow weirs to equalize this.

Guess where the primary clarifiermechanism problems have been at thisplant?

Another observation worth mention-ing is that, with the sludge pump runningat 100% speed, the sump would vortexand the pump would draw water throughthe blanket. To correct this, the speed ofthe pump was varied to find an optimal

speed set point that did not vortex, butstill provided favorable flow rates. Thiswas completed over a number of cycles.By optimizing the speed of the pump toavoid vortexing, the amount of waterbeing pumped was further reduced, con-serving sludge holding tank volume andsludge disposal capacity.

Cost summaryTo completely rehabilitate a primary

clarifier — 160 man hours plus $40,000in material. Cost of taking a primaryclarifier tank out of service for inspec-tion — about 20 man-hours. Cost of re-alizing the primary clarifiers are notbalanced — priceless!

The technologyThe basic principle used by the Ka-

jaaniTS meters is that the transmittermeasures the time of flight of a mi-crowave signal in the process medium.The time of flight depends on the per-mittivity of the measured medium. Fororganic or inorganic substances, it ispractically constant, whereas the permit-tivity of water is considerably different.

composition of solids, thus allowing reliable single-point calibration.

• There are no moving parts, therefore the units are practically maintenance-free.

• Impurities on the ceramic measure-ment antenna have minimal impact on results, due to the representative method of measurement.

• Additional selectable current output signals are available: either process temperature or process conductivity.

Thus, the measured change in permittiv-ity allows the total solids content in themedium to be calculated. The transmitterflow-through design gives a representa-tive measurement and effectively elimi-nates the risk of plugging.

In wastewater processes, microwavetechnology has several advantages overother types of solids measurement:• The start-up and calibration are

performed within a few minutes. • There is no reaction to changes in the

• The KajaaniTS uses special ceramic sensors that are resistant to dirt accumulation and provide long-term measurement stability.During the commissioning of the Ka-

jaaniTS meters at Greenway, a series ofsamples were taken using the special sam-ple feature of the transmitter. While thesample feature is enabled in the instru-ment, a grab sample is taken as close tothe measuring element as possible. Sam-ple ports were installed using saddle teesduring installation. Once a number ofsamples were taken, they were comparedto lab results and an average offset wasdetermined and entered into the transmit-ter. Figure 4 illustrates the correlation ofthe online instrument to lab results.

The City of London has experiencedproblems related to sludge accumulationin the primaries, following snow meltsand rain events during the winter andearly spring. The implemented automa-tion strategy ensures that solids are notbuilding up in the clarifiers and poten-tially damaging equipment. Since imple-mentation of the new meters, there hasbeen no mechanical breakdown due toheavy sludge buildup.

The most recent preventative mainte-nance has shown a considerable reduc-tion in mechanism wear, and the numberof replacement parts being used duringthis process has been significantly re-duced. No longer are complete chain andsprocket assemblies being replaced. Be-fore the density meters were installed, itwas common to take a clarifier out ofproduction and completely drain andclean a tank to replace broken flights andchain.

With the density meters, the operatorsare able to keep ahead of the sludge vol-umes. The system automatically variesthe amount of time each sump ispumped, and the density. High sludgedensity occurs when blanket levels areleft to build up. The implemented systemhas built-in adjustability to allow forcompression settling, keeping the densityof the sludge between 3% and 4%.

Solid waste management is con-cerned with the creation, avoidance, re-duction, collection, transport, processingand/or disposal of waste materials. Prop-erly done, it will ensure that there areminimal negative effects on humanhealth; that any effect on the environ-ment is manageable; that natural re-sources are maintained; and that theaesthetic and socio-economic values ofaffected communities are not degraded.

All too often, government authoritiescharged with following and guiding theenvironmental hearing process into solidwaste management have unfairly frus-trated the applicants, in an otherwisesmooth process, by leaning toward inter-veners’ concerns or by changing therules of engagement. This has led toextra costs for applicants and subsequentdelays in decisions by hearing panels.

The reasons for this may includethe desire of elected officials to avoidangry voters on contentious solid wastemanagement issues; a lack of accurateinformation about fiscally viable, envi-ronmentally-appropriate solutions; or fo-cusing too soon on a course of actionwithout full investigation of all reason-able options.

To overcome these constraints, engi-neers must effectively engage the publicand decision-makers, and persuade themof the merits of the science and engi-neering behind their proposed solutions.

Governments can assist this processby providing greater certainty and trans-parency in the environmental assessmentand approval processes which dictate theapproach to identification, screening andselection, construction, and operation ofa range of reasonable alternatives.

Waste Managementcan provide useful products. Aerobic andanaerobic composting systems producestabilized organics; so do sanitary land-fills after a very long time.

In most cases, the products from com-posting systems can safely be used in theagricultural industry. If there are doubtsabout their safe use, they can be appliedas cover for sanitary landfills, both oper-ating and closed. Landfills have systemsin place to deal with any contaminantwhich prevents the use of the product inagriculture.

Methane that is released into the at-mosphere can cause up to 20 times thedamage as the same amount of carbondioxide. Therefore, it is very importantthat methane emanating from a sanitarylandfill be captured and burned off in asystem using the gas’s energy, or simplyflared off.

Incinerating waste converts all carboninto energy and in the process emits vastamounts of carbon dioxide. By compar-ison, composting, either by aerobic oranaerobic means, has a product consist-ing largely of carbon which can be rein-troduced into the soil and hence has avery small carbon footprint.

• Anaerobically biodegrade the organic fraction of the waste stream to recover methane for energy, and use the resulting biodegraded material.

• Incinerate, change the form, and reduce the volume of the combustible fraction of the waste stream and recover energy while safely disposing of or using the products of combustion.

• Landfill waste in a safe location, using methane and other gases as a source of energy. Residual wastes still remaining, fol-

lowing each stage, would be consideredfor treatment in the next or succeedingstages.

In order to determine the most appro-priate solution, engineers follow aprocess that begins with defining thesolid waste management challenge to beresolved, and identifying regulatory andother compliance requirements. Theythen evaluate the technical feasibility,costs, and potential environmental andsocio-economic impacts of appropriateoptions to assist decision-makers in de-termining the preferred alternative.

Techniques for managing our waste

What many people don’t realize isthat glass waste is neither a pollutant, noris it present in large volumes in any san-itary landfill.

Why recycle glass then, particularlysince the sand used to make glass is oneof the world’s most abundant natural re-sources? For the same reason we chooseincineration as a waste management sys-tem of last resort. The production ofglass from raw materials requires a greatdeal of energy. Melting recycled glassshards (called cullet) requires far less en-ergy to be converted into useful glassproducts.

Professional engineers are in the bestposition, based on their skills and expe-rience, to identify a range of appropriatesolutions that take advantage of the ben-efits of technology and minimize envi-ronmental and socio-economic impacts.

Drinking Water

Justice O’Connor also saw a strongrole for the federal government, particu-larly in ensuring First Nations had accessto safe drinking water. He encouragedFirst Nations and the federal governmentto formally adopt drinking water stan-dards, applicable to reserves, that are asstringent as, or more stringent than, thestandards adopted by the provincial gov-ernments.

Ten years after the Walkertondrinking water crisis, there arestill major gaps in Canada’s na-tional framework for drinking

water protection, and worrying evidenceof inequitable access to clean wateracross the country, according to a new re-port from Ecojustice (formerly the SierraLegal Defence Fund).

In 2008, the Canadian Medical Asso-ciation reported that 1,766 drinking wateradvisories were in effect across Canada.The Ecojustice report says that unequalaccess to safe drinking water in Canadais particularly evident in Canada’s FirstNations communities and in rural and re-mote communities. As of April 30, 2010,there were 116 First Nations communi-ties across Canada under a DrinkingWater Advisory, with a mean average du-ration of 343 days. In rural Canada, it isestimated that 20–40% of all rural wellshave nitrate concentrations, or coliformbacteria counts, in excess of drinkingwater guidelines.

Issues with the provision of safe drink-ing water can in part be attributed to theabsence of national legally-binding stan-dards in Canada, unlike in the UnitedStates and the European Union. Instead,Canada has voluntary national guidelines.Provinces establish their own standards,which may, or may not, meet those guide-lines. According to the report, this leavessignificant populations, such as First Na-tions and rural communities, vulnerableto waterborne diseases, boil water advi-sories, and associated health effects.

The patchwork of drinking water lawsacross the country also means that, de-pending on which province or territorypeople live in, they may have access to ahigher standard of drinking water thanthose living elsewhere.

Justice Dennis O’Connor, in his reporton the causes of the Walkerton water cri-sis, emphasized the importance of legally-binding standards for protecting the healthof Canadians, when he concluded thatdrinking water quality standards “shouldhave the force of law.” He added that“conservative and enforceable water qual-ity standards are an important basis for amulti-barrier approach to water safety.”

The purpose of the Ecojustice reportis to highlight one of the gaps that existin Canada’s framework for drinkingwater protection - the lack of consistentand binding drinking water quality stan-dards across Canada - and to outline thenecessary steps and actions to addressthat gap.

The authors of this report do not rec-ommend a major overhaul of drinkingwater responsibility in Canada. However,they believe that maintaining the statusquo will lead to greater health risks andincrease the likelihood of another drink-ing water tragedy. They recommend thatthe current system be strengthened, sothat a safety net of legally-binding stan-dards apply to all Canadians, includingFirst Nations. They also recommend thatresponsibilities and accountability of allstakeholders be clearly established andarticulated.

Drinking Water

Water storageIn Nunavut communities, there are

three types of water storage: naturallakes, man-made storage reservoirs, andsteel tanks. A small community that de-pends on stream flow must have steelstorage tanks, whereas larger communi-ties have man-made storage reservoirs.

The earthen reservoir has two restric-tions: one metre free board to satisfy damsafety guidelines, and 1.5 m at the bot-tom for pump submergence. Normally,this type of reservoir is lined and madenon permeable. Every summer, it is filledfrom stream flows either by gravity feed,or by pumping.

Stream flows freeze up and are not ac-cessible for almost nine months of theyear. The top two metres become frozenon the surface of the storage reservoir,and remain frozen for almost ninemonths of the year. Therefore, the intakeis fixed at approximately one metreabove the bed level of the reservoir,where the water never freezes.

Natural lakes are uncontrollable and,in some cases, overflow arrangementsare made to maintain the water level. Thequantity of intake water is regulated andproportional to the population of thecommunity. It is considered roughly 90litres per day, per person. For emergen-cies, like fire protection, there is no limit.

Fire protectionThe reservoir must also provide water

storage to fight fires within the commu-nity. In 2004, the Northwest TerritoriesWater Board published a Good Engi-neering Practice Guideline. This docu-ment recommends that a minimum of60,000 litres of storage for fire protec-tion be provided in the reservoir for acommunity that is serviced by a truckhaul system, if the source is not availablethroughout the year. In addition, thepumping facility should be capable ofsupplying a minimum of 1,000 litres perminute from the reservoir to the watertrucks for fire protection.

Water treatmentWater treatment consists of an intake

system, disinfection process, and the fill-ing of water trucks with potable water.

Nunavut, “Our Land”, is thelargest part of the Arctic, andthe newest and largest Fed-eral Territory of Canada. It is

one fifth of Canada’s land mass, andmade up of 1,932,255 km2 of land and160,935 km2 of water. The current popu-lation is roughly 29,500.

Interestingly, one fifth of Nunavut iscovered by freshwater. In Nunavut, it canbe said: “Water, water everywhere, butmuch too hard to drink.” The Arctic wa-ters are frozen most of the year with icefloes and the land is covered with sheetsof ice, water pools, and rivers. Anygroundwater aquifer is merely a dreamdue to the deep permafrost.

Nunavut has four hydrologic periods:snow melts; outflow breakup period; asummer period with no ice cover andhigh evaporation; and a winter periodwhere ice cover thicker than two metresexists on lakes.

Surface water managementThe federal Crown, through Indian

and Northern Affairs Canada (INAC), re-tains ownership of the surface water inNunavut. Surface water use is licensedby the Nunavut Water Board. INAC is re-sponsible for the development, imple-mentation and interpretation of alllegislation and policies relating to itswater management in Nunavut. It is alsoresponsible for inspections of licensedoperations in Nunavut.

1. Intake Pipe: This is a single or dualsystem, heat-traced HDPE pipe. Thepipeline follows the gradient of the dykeof the water reservoir, or the bank of thenatural lake. The submerged end has amesh, which prohibits any fish or foreignobjects from entering the pipe. Pipingrests about one metre above the bottomof the water body to reduce turbidity inthe water supply.

Pipe segments that are most vulnera-ble to freezing are the inclined shaft in-take from the water body and the truckfill arm. The truck fill arm will drainback through the supply piping into thewater storage tank at the end of eachpumping cycle. A valve is incorporatedinto the piping to provide a vent to en-sure the required drainage. Freeze pro-tection of the intake is achieved by heattracing. Existing casing pipe is coveredwith 50 mm of polyurethane foam insu-lation.

2. Disinfection: Nunavut’s surfacewater requires very little disinfection.Chlorine is the main disinfecting reagent(calcium hypochlorite 65%). A chlorina-tor is installed inside the water truck fillstation. Chlorine in powder form is im-ported from the south and stored for usethe rest of the year. Powdered chlorine ismixed with water in the chlorinator be-fore being injected into the water dis-charge pipe.

All drinking water is chlorinated, andhas a free chlorine residual concentrationof no less than 0.40 milligrams per litre(mg/l) at the time of loading into the

water delivery truck, and a free chlorineresidual concentration of no less than0.20mg/l at the time of delivery. A freechlorine residual concentration of 0.20mg/l is measured from the delivery hosenozzle after a thorough mixing of thechlorine and water and 20 minutes ofcontact time.

Immediately prior to the first deliveryof each day, the delivery hose nozzleand/or coupler are disinfected by a 5.25%sodium hypochlorite spray. Should thewater delivery nozzle and/or couplercome into contact with the ground, or anyother source of contamination, it is im-mediately cleaned of debris and then re-disinfected.

Drinking water is not retained in awater delivery truck longer than 24 hoursafter loading. Any remaining water in thetank is drained and not used for drinking.

3. Filling the water delivery truck:Each water truck tank, with a capacityranging from 10,000 to 15,000 gallons,has an opening on the top. The truck isfilled at the rate of 1,000 l/m. Each com-munity has two to three water trucks andthey are filled up in sequence. The rota-tion is such that one water truck is nor-mally available in the community with afull load of water. The water truck driv-ers also work after hours, on weekends,and during emergency situations.

Testing of the water is conducted bythe truck driver on each and every truck,either at the truck fill station, or in frontof the community office prior to deliveryto clients. Monitoring is done by testingfree chlorine residual. Monthly samplesare sent to an Iqaluit health laboratory fortesting microbiological parameters.

Water is distributed by trucks to thetanks of homes and individual buildings.Water is metered during delivery andusers are charged monthly for this serv-ice. Each community has a regular rateand a rate for delivery after hours.

Icebergs as an emergency sourceThe community that depends on

stream flows and storage, sometimes willrun out of stored water, especially inwinter. Then, they must look for differentnatural sources like icebergs. This is onlymanageable for small communities withpopulations of less than 200. The resi-dents cut the icebergs into pieces, trans-port them using komatiks pulled bysnowmobiles, and store them in water

storage tanks. These pieces of ice aremelted by heat traces, then the water isdisinfected and distributed following thestandard procedures of the community.

Quality managementNunavut communities themselves are

responsible for drinking water qualitymonitoring and management until thewater is delivered to the end user. TheDepartment of Health and Social Serv-ices of the Government of Nunavut

maintains Quality Control and QualityAssurance and enforces the guidelines.Individual home owners are responsiblefor maintenance and cleaning of theirown water tanks, to keep the drinkingwater safe up to the tap.

requires several additional steps, includ-ing applying the filter to a specialmedium in a petri dish.

This principle ofsubstrate-based chemistry is approved bythe majority of regulators worldwide for

In order to safeguard public health,drinking water operators must con-duct a multitude of elaborate tests,designed to isolate and identify in-

dicators of pathogens and other contam-inants. Beginning with proper samplecollection, traditional methods involveintricate preparation and meticulous pro-cedures, using highly-trained technicalstaff.

Some methods involve quantitativecounts to determine the most probablenumber (MPN) of organisms in a sam-ple, while others determine the presence,or absence, of such organisms withouttheir quantification. All these methodsrequire the addition of liquid, or solid,nutrient media to encourage coliformgrowth, while suppressing the develop-ment of other bacteria.

Another standard method relies on amembrane filtration method which con-centrates and retrieves a small number ofbacteria from a sample of water. Thismethod uses a cylindrical funnel and afilter attached to a vacuum manifold, and

the analysis of E. coli and total coliformbacteria in drinking water.

To obtain results, both methods(MPN and membrane filtration) requireseveral procedural steps, a minimum of18 to 24 hours of incubation time at35°C, and human visual interpretation.Given the restrictions from the requiredminimum incubation time, none of thesemethods can provide early warning de-tection or real-time alerting capabilities.

The contaminated water crisis inWalkerton, Ontario, in 2000, increasedawareness of the need for better detec-tion methods that included automation,on-site testing capabilities, reduced re-liance on human interpretation, and aquicker sample-to-result time.

Largely driven by the events of 2000,a technology was developed by a groupof scientists led by Dr. Stephen Brownand the departments of Chemistry, Envi-ronmental Studies, and Microbiology andImmunology, at Queen’s University inKingston, Ontario, with the aim of incor-porating recommendations from the On-tario Clean Water Agency.

Now owned by Veolia Water Solutionsand Technologies, the technology hasbeen developed into a commerciallyavailable product line, called ENDETEC.

reagents to detect both E. coli and totalcoliform bacteria, in an “all-in-one” car-tridge format.

The quantification of E. coli methodused by the TECTA system is performedthrough correlation with time to detec-tion, where it is related to the initial num-ber of cells and growth rate. No sampledilution is required and the results can beexpressed over a wide dynamic range.

The technology can determine levelsof bacteria in a sample (in colony form-ing units, or CFU equivalents) because itdynamically monitors kinetics of growthand expression of indicator enzymes.E.coli and coliform bacteria begin togrow and multiply once the cartridge isinserted into the instrument. At somepoint in time (the time to detection orTTD), the number of bacteria cells and

the amount of enzyme in each cellreaches a level where the signal crosses aparticular threshold. Since the growth isexponential in time, a plot of log (CFU)vs. TTD is linear and provides the cali-bration function (Brown, 2010).

By contrast with conventional meth-ods, the “all-in-one” polymer-partition-ing system provides simplicity, with aninstrument allowing for simultaneous in-cubation, measurement, and real-timemonitoring of the sample, all at once.Time saving is realized in part becausethe test cartridge contains all the neces-sary reagents to perform the determina-tion, thus eliminating the need for typicallengthy sample preparations. Operatorssimply add water up to the 100-ml leveland load the cartridge into the instru-ment. Additionally, on-site testing capa-bility eliminates the need to ship samplesto an outside laboratory, significantly re-ducing the time needed to obtain results.

An advantage of this new technologyis its real-time monitoring capacity.Without having to wait 18 to 24 hours for

incubation, it will alert the operator in aslittle as two hours for a severely contam-inated sample (~106 colonies); 14 hoursfor single cell detection; and 18 hours forpresence-absence.

In case of an adverse event, the in-strument will immediately display acolor-coded image on the user inter-face’s display screen. An audible signalis also heard, and wireless data transmis-sion configuration is available for imme-diate alerting on cellular phones, or other

Petrochemical Wastes

when cleaning a storage tank, a serviceprovider will remove sludge, prepare itfor disposal, and send it to a hazardouswaste landfill or incinerator.This processinvolves taking the tank offline and di-luting the sludge found in the bottom byadding light hydrocarbon-based fluids tomobilize the solids. Once removed, theliquid slurry requires solidification inorder to be suitable for disposal.

Each of these steps significantly in-creases the volume of material requiringdisposal. Add to this the safety risks in-volved with confined space entry into thetank, greenhouse gas (GHG) emissionsfrom transporting large volumes of ma-terial, and the costs of taking the tankoffline, and the traditional tank cleaningmodel can be costly, with a potentiallysignificant environmental footprint.

Government regulation driving change

As public concern for a cleaner envi-ronment drives stricter environmental reg-ulations, many companies are looking for

Refineries store feedstock,process and waste materials intanks and other storage con-tainers. Sludge accumulates

in the bottom of tanks; therefore, they re-quire regular cleaning to ensure optimalefficiency and effectiveness.

When making decisions regardingtank cleaning, refineries weigh severalconsiderations, including tank downtime, how to manage environmental andsafety risks, and what to do with theresidues. Due in part to stricter govern-ment regulations and new technologiesthat offer the ability to more safely re-cover material that was once consideredwaste, refinery operators are increasinglylooking to service providers that are notonly able to clean tanks, but also to helpminimize the environmental impacts ofwhat comes out of the tanks.

Moving away from traditional approaches

Conventional thinking in tank man-agement centres on disposal. Typically,

new, more sustainable ways of doing busi-ness. In Ontario, for example, new LandDisposal Restrictions (LDR) now preventhydrocarbon-contaminated sludge frombeing sent directly to land farms or land-fills.

Newalta has introduced a waste min-imization and product recovery-focusedapproach to tank cleaning to customersin the chemical and petrochemical in-dustries in Ontario, primarily in the Sar-nia Valley. Because this tank sludge isconsidered hazardous and must now un-dergo further processing before it can bedisposed of, the ability to minimize theamount of waste material requiring dis-posal is an attractive proposition.

Maximizing environmental and economic value

This new approach reduces the vol-ume of actual waste for disposal by up to95 percent and maximizes the recoveryof valuable hydrocarbons and water fromsludge. This reduces or offsets costs for

customers, by reducing transportationand disposal requirements and returninga valuable commodity that can go backinto production. Additionally, it signifi-cantly lessens the environmental foot-print of tank cleaning by:• Reducing GHG emissions associated

with transportation by operating on customers’ sites.

• Reducing the volume of material sent to landfills, incineration or other disposal methods.

• Recovering water that can be further treated by the customer and either reused as process water, which reduces the requirement for fresh water, or safely returned to the natural environment.

• Recovering a usable crude oil product with less environmental impact than that obtained through conventional drilling and production.

Tank managementThe typical tank management process

includes the following steps:1. Consultation, imaging and sam-

pling - Newalta works with the customerto determine the scope of the project andestablish expectations. Sludge is profiledusing infrared technology and 3D-mod-eling to analyze tank contents and deter-mine optimal processing methods.

2. Non-entry tank decontaminationand sludge suspension - Robotic or au-tomated technology reduces the need forconfined space entry. Tank materials areliquefied to mobilize and suspend solidsin the sludge, which is then removed tomaximize product recovery potential.

3. Centrifugation, filtration and prod-uct recovery - Newalta’s centrifuges arespecifically engineered to manage oilysludge found in tanks. Depending on thesludge profile and contaminants in thetank, a decanter centrifuge is used to sep-arate solids and hydrocarbons, or a tri-canter to separate oil, water and solids.In the case of sludge with low levels ofsolids, a filtration system can be used.

4. Disposal - By recovering oil andwater from sludge, the amount of solidsrequiring disposal is reduced by 85-95percent. The remaining solids are sentoffsite for safe disposal.

5. Tank cleaning and coordination ofinspection and maintenance - After thesludge is removed, tanks are cleanedusing safe entry protocols. If required,

inspection and maintenance are coordi-nated with appropriate third parties.

heaters. This coke lessens the efficiencyof energy transfer so the heaters period-ically require de-coking to be able tocontinue to operate efficiently.

The de-coking process is known as“pigging” and uses large volumes ofwater to push devices called “pigs”through boiler lines to remove built-upcoke. The water used in this process be-comes contaminated with fine coke par-ticles (coke “fines”) and must be properlydealt with by refinery operators. The tra-ditional approach to managing piggingwastewater has involved disposal in awell or transportation to a wastewatertreatment facility for processing.

Newalta has developed a mobilewastewater treatment process that closesthe loop on pigging water. It uses a com-bination of mobile equipment, includinghydrocyclones, settling tanks and highflow horizontal filters, to process and re-turn water in a ready state to the de-cok-ing unit for reuse. It runs continuouslyduring the pigging operation and in-cludes the following basic steps:• Step 1: A centrifugal pump pulls waste-water from the operator’s storage tank

Wastewater Systems

50-100 mm in diameter and can be shal-lowly buried following the terrain. Instal-lation can be done by directional drilling,further reducing the impact on the com-munity and the environment.

No expensive lift stations are needed,and the watertight effluent sewer systemdoes not require manholes. This signifi-cantly reduces costs, while also eliminat-ing critical points where spills can occur.Interceptor tanks are high quality, butsimple vessels that provide emergencystorage and remain almost unnoticed byhomeowners.

Packed-bed treatment systemsAfter primary treatment in the inter-

ceptor tanks, liquid effluent usually mustreceive secondary or advanced treatment.Effluent sewers can discharge to tradi-tional municipal treatment plants and canbe connected into a regional gravitysewer, but many are part of satellite ordecentralized cluster systems. In decen-

Many rural communities thatuse septic systems haveoutgrown that technology.Some are experiencing

widespread failure of aging systems.Others are growing, but their soil condi-tions won’t accommodate additional sep-tic systems. Larger communities want togrow, but their existing sewer systemscan’t accommodate new connections. Inall these cases, neither conventional sep-tic systems, nor gravity sewer systems,are feasible.

Effluent sewers are a proven and sus-tainable solution for decentralized andrural wastewater collection acrossCanada, and in many other countries.Not only can effluent sewers serve ruralareas, but they are also a cost-effectiveway to serve fringe development, justoutside towns that do not want to expandtheir conventional sewer system.

How effluent sewer systems workIn an effluent sewer system, primary

treatment takes place in a small, water-tight, underground tank (called an inter-ceptor tank) at each property. Raw wastesseparate into solid sludge, floating scum,and liquid effluent; this is a passive andreliable process, requiring no energyinput. The solids remain in the tank foryears. Because the anaerobic biologicalprocesses in the tank tend to consume thesolids, most tanks only need to bepumped every ten or more years, withlarger tanks even less frequently.

Unlike solids, clarified liquid effluentremains in the tank for only a couple ofdays. Then it is conveyed from the tank tothe next treatment step. Systems in whichthe effluent flows by gravity are calledseptic tank effluent gravity (STEG) sys-tems. If each household has a pump thatpushes the effluent, the system is called aseptic tank effluent pumping (STEP) sys-tem. Both types of connections can existon the same collection network.

Because only liquid effluent ispumped intermittently, special small, en-ergy-efficient pumps (typically one-halfhorsepower) are used, costing the home-owner only pennies a month for electric-ity. Effluent collection lines are typically

tralized effluent sewer systems, furthertreatment of wastewater is often donecost-effectively in packed-bed (media)filters; again this is a passive, reliableprocess that requires minimal energy totrickle effluent over the filter media bed.

Traditional sand filters are still usedin some communities. However, engi-neered filter media provides more sur-face area than sand to facilitate thegrowth of microorganisms. It also pro-vides more open pore space for themovement of oxygen. For example, inAdvanTex® treatment systems, manufac-tured by Orenco Systems®, Inc., effluentcirculates over hanging curtains of a spe-cific synthetic fabric. A single 2400 x5000 mm AX100 pod can treat designflows of 19,000 litres per day (LPD) ofresidential-strength wastewater, whichwould require 93 square metres of sandfilter to treat.

Packed-bed filters can be built, or in-

Both pumped and gravity-discharge lots can be connected to the same small-diameter effluent sewer system. (Credit: Orenco System Inc.)

stalled, as needed in sequential modulesto match phased construction. They con-sistently produce high-quality effluent atlow operational cost, even with widevariations in flows and waste strength.

Case Study - Victoria, PEIVictoria, Prince Edward Island, is a

small but popular tourist community,with a peak season between June andSeptember. Its wastewater system, de-signed by Engineering TechnologiesCanada (Stratford, PEI), in cooperationwith Harland Associates 02 Inc., consistsof about 48 STEG systems. Effluentfrom these flows to a lift station thatpumps it to the treatment plant. The ef-fluent sewer system also incorporatesfive residential STEP systems and twocommercial STEP systems.

Campbell’s Concrete Ltd. of Charlot-tetown, PEI, manufactured the interceptortanks, and Atlantic Purification Systemsof Dartmouth, Nova Scotia, supplied theeffluent sewer and treatment equipment.

The treatment system consists of tenAdvanTex AX100 pods, with room toadd an additional five units, if the com-munity grows. The modular system ac-commodates the large seasonal variation

in flows. During winter months, flowsaverage 22,7000 LPD and only one-thirdof the treatment system is used. Duringthe summer, flows rise to 49,200 LPD,and the entire modular system is utilized.

After secondary treatment in the Ad-vanTex pods, effluent is dispersed to theground. The system has two drainfields:

a pressure dose sand bed, and a drip irri-gation system. The pressure dose bedworks all year round; the drip systemcomes online automatically in mid-Juneand goes offline September 22. Duringthese months, both drainfields are in op-eration.

Wastewater Systems

Once a month, they check in and uploadoperation data to a secure Web site. Theyalso alert the operator to problems, suchas excessive pump cycles. In many cases,the operator can diagnose the problemremotely and adjust settings to correct it.Even if a site visit is required, the opera-tor arrives prepared with informationabout the likely cause of the problem,such as a stuck float or a leaking toilet.

Several models for wastewater systemmanagement exist throughout NorthAmerica. While some require the home-owners to take responsibility for equip-ment located on their lot, a private orpublic utility is typically better equippedand more efficient in responding to onsiteservice needs. Therefore, the preferredmodel is for a responsible managemententity (RME) to accept that responsibility.The RME may be as small as a home-owners’ association, or as large as aCounty. Web-based services, such as On-lineRME (www.onlinerme.com), allowjurisdictions to verify that all on-lot sys-tems in their area are being maintained ingood order.

Effluent sewers can be ideal solutionsfor villages and small cities, but there isno limit to the number of lots connectedto the collection network. Many largercities have incorporated this technologyinto their overall sewer management sys-tem, where the effluent sewer servesthousands of homes and commercial lots.This allows city engineers to choose thebest option to serve various areas in thecity, without being limited to only grav-ity sewers.

Case Study: Habitat Acres, AlbertaSten Berg, a farmer, livestock pro-

ducer, and consultant, wanted to create asustainable housing development on 27.5hectares of his land near Sherwood Park,Alberta. Habitat Acres, a 29-homeplanned community, is the result. It in-cludes an 18.2-hectare nature reserve,two waterfowl nesting areas, and the firstself-contained effluent sewage treatmentsystem ever approved in Alberta.

To maximize open space and preservewetlands, Mr. Berg wanted to reduce lotsizes from the usual 0.8-hectare mini-mum, so conventional septic systemswere out of the question. An Orenco ef-fluent sewer with AdvanTex treatmentsolved the problem. Onsite SpecialtiesInc., of Sherwood Park, supplied the col-lection and treatment system.

Each of the 29 lots has a 4,500 litreconcrete interceptor tank, supplied by Al-berta Wilbert Sales, Edmonton. Effluentis pumped to three AdvanTex AX100pods. After treatment, effluent is dis-charged to a drip irrigation system.

Managing effluent sewer systemsRemote monitoring allows utility

companies, or other authorities, to effi-ciently manage decentralized systems. Inboth Victoria and Habitat Acres, STEPunits at individual homes are equippedwith Orenco VeriComm control panels.The AdvanTex treatment systems arealso controlled by TCOM telemetry con-trol panels from Orenco.

VeriComm panels communicate withthe system operator, via the home’sphone line or broadband connection.

Other benefits There are may other benefits from

using an effluent sewer system, includ-ing:• In most systems that are built toserve new developments, the cost of theon-lot equipment is included in thehomeowner’s mortgage, so upfront in-vestment by the community or developeris minimal. • Small-diameter collection lines canbe installed in shallow, narrow trenches,or directional drilled, minimizing dis-ruption in the community. Lines followthe contour of the land, avoiding difficultand expensive deep trenching.• Service can begin as soon as the firsthousehold in a new development is con-nected. No minimum velocity is requiredfor the effluent sewer network, as solidsare excluded, simplifying design, instal-lation, and operation.• Effluent sewer systems are water-tight, eliminating infiltration and inflowcommon to gravity sewers, and reducingthe hydraulic loading on the treatmentplant.• Sludge management is greatly re-duced through natural, passive, anaero-bic digestion in the interceptor tanks,simplifying treatment plant design andminimizing life-cycle costs.• Since primary treatment occurs ateach home or business, abuse of thesystem, such as disposal of chemicals,generally affects only the household re-sponsible.• Risks are minimized and distributedas malfunctions generally affect only onehousehold at a time. In the event of a mal-function or natural disaster, the septictank provides reserve holding capacity.• Properly maintained effluent sewersystems require fewer personnel and lessheavy equipment to service than othersewer systems do.

Together, effluent sewers and mediafilter advanced treatment form a sustain-able and robust system that uses minimalenergy, safeguards groundwater and theenvironment, and imposes costs fairly onthe users. Communities of all sizes canbenefit from this technology.

culations, need some encouragement.When I put the textbook down, I see

the students’ interest pick up. Our newyoung professionals are truly concernedabout real issues, not just textbook infor-mation. As educators, we in the class-room must allow our students to explore,and we call on all employers everywhereto allow our graduates to continue ex-ploring. Take advantage of their enthusi-asm — don’t just tell them to operatewhat has already been built. Give thempermission to use their creativity to trysomething new. They may just surpriseyou with something affordable, sustain-able, simple.

I believe that greater emphasis in theclassroom on what is relevant and practi-cal to the student will produce a veryvaluable asset to the employer. Greateremphasis in the classroom on what is rel-evant and practical to the seasoned pro-fessional will achieve this desired endresult. So I remember what has beenmost relevant to me as I have worked inthe field, and I pass this on. And just incase I might get out of date, I ask those inthe field what is relevant to them, and Ipass this on as well.

It is when students are told to closetheir textbooks that they become cre-ative. Case in point: Class is given timeto consider turning various wastewatersinto that much needed resource we callpotable water.

When students consider a form of re-verse osmosis to produce potable water,they have a technically correct textbookanswer. However, they soon realize that fi-nancially they would be broke due to thehigh cost of pressuring water against aconcentration gradient, and also the highcost of cleaning or replacing a membrane.

When students consider a form of de-salination to produce potable water,again they have a technically correct text-book answer. However, they realize thatenvironmentally they would be choosingan activity that can be described as un-sustainable since it is very energy-inten-sive and emits thousands of tonnes ofcarbon dioxide yearly.

They have learned that, sometimes, atechnically correct textbook solution

As one who has spent much ofhis career as an environmentalengineer dealing with munic-ipal and industrial wastewater,

I am used to being the butt of jokes whenthe question comes up at social hour: “So,what do you do for a living?”

The reaction to my reply is typicallypredictable. Almost immediately, a lookof pain appears on the person’s face atthe thought of sewage. I sense them lean-ing away from me, as if they might catchsomething. But almost simultaneously,an expression of sympathy wells up intheir eyes as if they are truly sorry for myunfortunate lot in life!

The reality is that I love sewage! Bothmunicipal and industrial! After all, pol-lution has given me great employmentand a challenging career. Even when theeconomy takes a dive, pollution does notgo away.

As a professor of environmental engi-neering, it gives me great satisfaction tointroduce students to real-time waste-water treatment issues and concerns. Iam constantly closing up the textbook,leaving it on the podium, in favour ofpresenting actual wastewater scenariosand soliciting student solutions.

What students ask forToday’s students ask for relevancy.

They ask: “What do we really need toknow?” and “Why do we need to knowthis?” They expect practical courses, notjust theoretical. If a college or universityprofessor’s enthusiasm for water andwastewater treatment excites students togo further and make environmental engi-neering and science their career direction,then I’m all for it. If presenting materialsthat are “as relevant as possible” andwalking students through “possible situa-tions we could get into” also motivatesthem, then I’m all for that, as well.

Both new and seasoned water andwastewater professionals have relevantand practical information available tothem through many professional organi-zations and publications. Environmentalstudents, however, who may be feelingthat they’re being dragged throughorganic chemistry, cell physiology, andnumerous physics and engineering cal-

should come with a warning. In this case,they learned that improved water man-agement should mean lower water usage,not unsustainable development.

Not to sound too simple, but whenstudents consider a form of fine filtra-tion and carbon adsorption to begin pro-ducing potable water, now they realizethey have a method that not only works,but is both affordable and sustainable.They are quick to see the “green” ad-vantages.

What students needToo often, the classroom instructor

emphasizes the more sophisticated tech-nologies, and the large-scale applicationsof these technologies, likely because wethink that’s where the students will findgainful employment. Too often, consult-ants and contractors look for the biggerprojects to bid on, likely because theythink these projects will provide the mostjobs.

Of course, the reality is that industrylooks for the best return on the dollar,and local municipal council decisionsmust be based on costs, and costly waterand wastewater treatment is not alwaysplaced high on the priority list.

We must look to the classroom for thefirst step in overcoming these economicchallenges. Young municipal plannersmust graduate understanding environ-mental priorities; young township in-spectors must graduate understanding thesignificance of both properly designed

and properly constructed rural systems;young engineers must graduate under-standing the importance and necessity ofthe smaller and simpler systems, in addi-tion to the scaled-up and sophisticated;young environmental technologists mustgraduate understanding that the afford-able and sustainable are just as valid op-tions as the costly and complex.

What students wantToday’s students want real jobs.

Speaking with my environmental tech-nology students each year, I emphasizethat they will, in time, become the pro-fessionals in their facilities. They will

come to know their equipment and stan-dard operating practices inside and out,including which procedures work andwhich do not. I emphasize that, in time,the graduate as the new professional willbecome a valuable part of the on-sitecontinuous improvement process. I em-phasize that new operators must alsolearn to speak up and tell their supervi-sors what is and is not working, and whatthey do and do not need. And so envi-ronmental education continues beyondthe classroom.

Chemistry, biology and physics arenecessary for a good background and in-

troduction to environmental education.Yet it is the real-time input of the sea-soned professional that introduces a verynecessary component to that education.If it is invited, please give it. If it is not in-vited, please offer it.

That’s what students want so they canbe prepared and useful after graduation.That’s what employers want so they canconfidently put their newest team mem-bers to work right away. It’s a win-win-win situation for the student, the employerand the environment.

ment and solid waste management, over 40%of facility managers are over 50 years of age.

2. Shallow candidate pools. The mostchallenging positions for water/wastewaterfacilities to recruit and retain were those ofintermediate operator or operator in training(OIT). Over 50% of facilities surveyed re-ported hiring for these positions over the pasttwo years and close to 30% expect to hire an-other in the next year.

Facilities in the study reported recruitmentwas becoming increasingly difficult for allpositions and experience levels. While solidwaste management facilities reported thatskilled labour positions were the most in de-mand, no recruitment difficulties for thesepositions was expressed. Conversely, the re-cruitment of facility managers was a notablechallenge, as 59% of facilities surveyed re-ported difficulty in hiring for this role.

The current shortage in qualified opera-tors shows signs of only increasing as quali-fied workers reach the age of retirement.According to the study, the labour shortagewill be magnified in small, remote commu-nities that have fewer resources, a smallerlabour pool to draw from, and lose top talentto larger communities.

3. High employee turnover. For the pastthree years, turnover in water/wastewater

treatment facilities has been nearly doublethat of solid waste facilities. One-third of thefacilities surveyed had difficulties retainingworkers at the intermediate experience level.However, both water/wastewater treatmentand solid waste management facilities havereported much lower turnover in 2009 than inthe previous two years. This is likely due tothe economic conditions of 2008/2009.

Many older practitioners who are close toretirement are staying in their positions to re-cover some lost retirement income, andyounger practitioners are not moving aroundas much due to fewer opportunities in boththe public and private sectors. Also, in timesof economic uncertainty, the public sector ismore appealing due to the job stability.

Unless something is done, turnover couldrevert back to the levels of 2007 and 2008,which for each industry were double the cur-rent turnover.

4. Lack of resource and training support.Many municipalities feel the training re-sources available to them are insufficient, andthat there is a lack of appropriate trainingcourses to satisfy the professional develop-ment needs of practitioners.

Since current training and professionaldevelopment for practitioners in solid wastefacilities tend to focus on the technical as-

pects, the lack of “soft skill” training has ledto considerable gaps in the industry in areassuch as leadership skills, communicationskills, and computer skills; this hinders apractitioner’s abilities to move up in theworkforce.

Focus group participants cited lack ofrecognition of training and experience, bothbetween provinces and internationally, as aconsiderable hindrance to operator mo-bility. Programs created to eliminate thisproblem would also serve as an incentive to-wards greater employee retention.

5. Raising awareness. Another issue thatmunicipalities identified relating to solidwaste management was ensuring that careersin that industry are recognized as respectablecareers that promote environmental healthand protection.

Unfortunately, there is limited careergrowth in smaller facilities and career pathsfor solid waste management practitioners arenot always clear. Focus groups identified thatlarger facilities, with more roles and positions,do not have this problem, and practitionershave an easier time advancing their careers.

Proposed federal wastewater regulations

criticized

A coalition of environmental groups issubmitting formal comments on the fed-eral Wastewater Systems Effluent Regu-lations that were made public on March20, 2010. They feel that, despite mandat-ing a minimum of secondary level sewagetreatment for all Canadian municipalities,the regulations contain significant loop-holes that would see sewage dumpingcontinue at current levels for many citiesuntil as late as 2039.

The formal comments being submit-ted by environmental groups recommendthat timelines for upgrading facilities beshortened to five years (or 2015) for highrisk facilities, ten years (or 2020) formedium risk facilities, and 15 to 20 years(or 2030) for low risk facilities, and thatmajor loopholes for key pollutants andcombined sewer overflows be closed.

Plan to reduce fluid tailings approved

The Energy Resources ConservationBoard (ERCB) has conditionally ap-proved a plan by Suncor Energy Inc. forimproving fluid tailings management. TheERCB has also approved construction andoperation of Suncor’s first commercialapplication in the Alberta oil sands of anew technology designed to reduce thevolume of fluid tailings.

Suncor’s Tailings Reduction Opera-tion (TRO) involves converting fluid tail-ings into a solid landscape, suitable forreclamation. The project is located 40 kmnorthwest of Fort McMurray.

The ERCB believes that application ofTRO will enable Suncor to reduce thevolume of fluid tailings remaining at theend of the project life by 33 million cubicmetres (about 30%). Suncor has alreadycommitted approximately $450 million toTRO technology and other measures de-signed to improve tailings management.

So far, oil sands operators have com-mitted more than $1 billion in tailingspond upgrades.

Nova Scotia restricts bottled water use

The Nova Scotia government recently an-nounced a new policy to eliminate thepurchase and use of bottled water by allgovernment departments with access topotable tap water. The policy emphasizesthe high quality of Nova Scotia's tapwater and reduces the amount of plasticentering the province's waste recyclingsystems. The policy will apply only togovernment departments where potabletap water is available and not to public in-stitutions such as hospitals. It will notapply to private sector organizations.

The policy allows a department to usebottled water only in certain circum-stances, including times of emergency, orif potable tap water becomes unavailable.

Many organizations in Canada, such asuniversities and municipalities, have de-veloped a similar policy to reduce plasticwaste. The Federation of Canadian Mu-nicipalities urges all members to phaseout the sale and provision of bottled waterin municipal facilities.

Concerns about increasedoutflow from North Dakota

Manitoba Premier Greg Selinger has ex-pressed his disappointment after learningthat North Dakota has increased the flowof water from the Devils Lake outlet from100 cubic feet per second (CFS) to ashigh as 250 CFS, without a filter being inplace.

“While we empathize with the resi-dents of Devils Lake and the floodingthey endure, it is essential that we protectManitoba's waterways from risk,” MrSelinger said. “It is imperative the ad-vanced filtration system be put in placeto prevent harmful algae, pathogenic bac-teria, fish parasites and fish diseases fromentering Manitoba.”

The Canadian and the US federal gov-ernments reached an agreement to installan advanced filter in 2005 but the filteris not yet in place. The Manitoba govern-ment has been at the forefront of press-ing the federal governments in Canadaand the US to help find a solution to theproblem.

Manitoba leads efforts toreduce phosphorus

An effort led by Manitoba to reduce phos-phorus in consumer products acrossCanada resulted in a ban going into effect,July 1, 2010 on dishwashing detergentcontaining phosphorus. The national ban,affecting household dishwasher and dish-washing detergent containing more than0.5 per cent phosphorus, is consistentwith the measures contained in Mani-toba’s Phosphorus Reduction Act, passedin June 2008.

Manitoba’s actions, similar legislationpassed in Quebec, and lobbying by theCanadian Specialty Products Association,prompted the federal government to intro-duce national standards on this product.

Additionally, in 2009, Manitoba fol-lowed Minnesota’s lead and introduced aban on the application of lawn fertilizers

In addition, golf courses, municipali-ties and agricultural areas are subject torestrictions under the Nutrient Manage-ment Regulations. Under these regula-tions, no fertilizer can be applied nearbodies of water. Buffer zones range fromthree metres along most rivers andstreams, to 15 metres along the Red andAssiniboine Rivers, and 30 metres alongLake Winnipeg.

Environmental groups challenge Ontarioʼs Open

for Business Act

Three Ontario environmental organiza-tions have stated their opposition to theOntario government’s proposed Open forBusiness Act.

The Canadian Environmental Law As-sociation, the Canadian Institute for Envi-ronmental Law and Policy, and Ecojustice,claim that under the proposed Act, Ontar-ians will lose fundamental legal rights es-tablished under the Environmental Bill ofRights, one of Ontario’s most importantlaws. The Open for Business Act will re-move the opportunity for public notice andcomment for certain industrial activitiesthat will be subject to a new environmen-tal approvals process. Citizens will alsolose the right to appeal approval of theseactivities through the Environmental Re-view Tribunal.

The groups have called upon the On-tario government to amend the proposedAct, so as to leave intact the public noticeand comment, and third party appealrights under the Environmental Bill ofRights.

will help Canadian businesses, schoolsand non-profit organizations engage cus-tomers and supporters by planting treeson their behalf in tropical, deforestedcountries that are the most effective inmitigating climate change.

“For $1 apiece, giving a Mokugift treeis similar to sending an e-card,” said NatZavier of Mokugift Canada. “After se-lecting the country where their tree isplanted, donors can display their trees on-line at Facebook, MySpace, Yahoo!, andmany other popular websites.”

Mokugift trees are planted with thehelp of local farmers practising environ-mentally sustainable forestry and agri-cultural methods in tropical zones inCentral America, Africa and Asia. Theplantings restock existing forests with na-tive trees that have been depleted and willcontribute to more diverse, productiveand economically sustainable land-usesystems. So far, approximately 10 billiontrees have been planted.

Ontario places strict conditions on York/Durham

sewer expansion

According to the Ontario government,strict conditions are being attached to theapproval of the new Southeast CollectorTrunk Sewer for the York-DurhamSewage System. The new project will ex-pand the sewer system to support YorkRegion's future growth in Richmond Hill,Aurora, Markham, Newmarket andVaughan. The region's population is fore-casted to grow from 930,000 in 2006 to1,500,000 by 2031.

Strict conditions will ensure the Re-gion builds and operates the sewer in away that protects human health and theenvironment. It will be required to mon-itor and report every year to show theproject is meeting all conditions of ap-proval. These conditions include:• Monitoring for potential impacts on

ground and surface water, as well as air quality during construction and operation of the sewer.

• Implementing and reporting on measures to conserve and use water efficiently, and to reduce inflow and infiltration of water into the sewer.

• Implementing and reporting on odour

Letter to the editorDear Tom,

Thank you so much for the education andencouragement you have provided meover these many years. When I wonderedas a new professional if I was accom-plishing anything, your editorial com-ments always reminded me that I was.

And now, as a seasoned professional,your editorial comments still push me todo and be the best I can. No longer in the"field" as an environmental engineer, Itake great pride in passing on what thecollective "we" know so that my gradu-ates can pick up where "we" left off.
