ON THE COVER:Operators at the Frank C. Amerson Jr. Water Treatment Plant in Macon, Ga., find that being proactive reaps rewards. So does providing input that can improve operations. The team’s leader, Gary McCoy, director of water treatment, is shown at a control valve (Rodney Hunt) in the plant’s pumping station. (Photography by David Makkers)
In the same week recently I heard from two professionals — one each from the wastewater and drinking water sides — about the merits of calling treatment plants something else, and giving people who work in them different titles.
From Sam Wade, deputy CEO of the National Rural Water Associa-tion: “The NRWA and state Rural Water Associations ... have launched the campaign to refer to the staff who operate water and wastewater sys-tems as water or wastewater system operations specialists.”
From Jack Saltes, P.E., wastewater operations engineer for the Wis-consin Department of Natural Resources Bureau of Water Quality: “The Water Environment Federation now refers to all wastewater treatment plants as water resource recovery facilities [WRRFs]. Suggestions have been made that the DNR also change the title ‘wastewater treatment plant operator’ to ‘water resource recovery specialist.’”
In both cases the thought is that these designa-tions better reflect what water facilities do and the skills, knowledge and expertise plant staff members have. “Simply put,” says Wade, “these positions are not just task-oriented jobs. They are professional career tracks that deserve to be recognized as such.”
In concept, yes
I am inclined to agree. On the wastewater side, I have advocated for the terms “clean-water plant” and “clean-water operator,” on the grounds the plants and people should be known for the wonderful end product they produce, not for the unpleasant raw material that comes in.
Water plants and their personnel seem less affected by any of the “yuck factor” associated with wastewater (or, more crudely, sewage). Still, an argument can be made for a name change. In Wade’s words: “Today, operation of water and wastewater systems is much more complex, has legal liabilities and requires a variety of professional skills, knowledge and experience, including certifications of varying degrees.
“Still, for the most part, it is a service taken for granted and viewed by the public more as a job rather than a professional skilled career track. A recent survey of over 1,850 system personnel of all-size systems and posi-tions asked: Which title — specialist, operator or technician — projects the skills, knowledge and expertise in the industry today?
“Seventy-two percent selected technician or specialist over the title of operator. When this type of response comes from within our own indus-try it is a clear indication that it is time for change.”
Change isn’t newWade notes that changes in job titles aren’t
new: customer service representatives replaced clerks and phone operators; administrative assis-tants replaced secretaries. He also observes that the Water Environment Federation used to be the Water Pollution Con-trol Federation, and the National Association of Clean Water Agencies was known as the Association of Metropolitan Sewage Agencies.
To Wade, changing the way we refer to water professionals will help attract new blood to an industry that is about to lose up to 65 percent of the workforce to retirement. “The largest loss will be in our nation’s rural and small communities, which compose 92 percent of the community water supplies in the nation,” he says.
He believes “specialist” titles that better reflect the professional nature of the careers will lead the public and government officials to view the people more favorably, leading to higher pay structures that will help attract more and better talent.
What’s the impact?
Will changing the names of plants and the titles of professionals by itself change public perceptions of the industry? Not likely — but the names and titles we use now force the industry to swim upstream, espe-cially on the wastewater side.
In any case, it’s a discussion worth having. WSO is deeply interested in your thoughts. Please express your opinion by sending a note to [email protected]. I promise to respond, and we will publish a sampling of comments in a future issue. wso

In some communities, property owners come home from work to find their lawn torn up by the utility department and start searching for the email address of their local council representative.
Not in Daphne, Ala., where customers are king, and the utility makes every effort to be proactive and talk to them in terms they understand.
“We’re not here to run a water utility,” says Rob McElroy, general man-ager of Daphne Utilities. “We’re here to supply water to our customers.”
That’s an important distinction in the eyes of McElroy and his team of Danny Lyndall, operations manager, and Larry English, water quality manager. “Costs are going to increase. Rates will go up,” McElroy says. “Having customers understand and support us is absolutely necessary. We have to communicate the value of water, in their terms.”
Effective customer communications are just one reason Daphne Util-ities has pulled in more than its share of awards in recent years, includ-ing rankings as one of the nation’s best small places to work from The Wall Street Journal and Inc. Magazine. Other honors include multiple Awards of Excellence from the U.S. EPA.
“You’ve heard the old saying ‘Good enough for government work,’ says McElroy. “Around here, we buck that attitude. ‘Good enough’ is not good enough anymore.”
Boosting production
Daphne Utilities serves some 11,000 water customers in the city of Daphne and surrounding communities on the east shore of Mobile Bay. It also supplies wholesale water to one small neighboring area. The utility, founded in 1953, is governed by a five-member board appointed by the city council. Besides drinking water, it provides wastewater treatment at

an award-winning 4.17 mgd water reclamation plant and supplies natural gas to about 4,000 customers.
Raw water is drawn from aquifers through a network of 11 wells 150 to 450 feet deep. The water is treated in a battery of smaller treatment plants at or near the well sites, and at a new treatment facility that increased total production capacity to 7.1 mgd. Peak customer demand is 6.5 mgd, and average summer demand is 4.5 mgd.
During treatment, lime is added for pH adjustment and sodium hypo-chlorite and chlorine gas are used for disinfection. At the main treatment and production facility, disinfection is accomplished through onsite gen-eration of sodium hypochlorite (a MicrOclor unit, manufactured by Pro-cess Solutions). Metering pumps (Siemens and Pulsafeeder), chemical pumps (Neptune) and chemical feed systems (Acrison and Coffman Sys-tems) support the rest of the treatment process.
Systemwide, treated water passes through several 100,000-gallon clearwells and eventually to the 200-mile distribution system, mostly 6- to 16-inch PVC or ductile iron piping. Two booster pump stations are equipped with Gorman-Rupp pumps. High-service pumps were supplied by Peerless. Storage consists of seven above-ground tanks and one reser-voir. A SCADA system (Dexter Fortson Associates) provides automated monitoring and control. About 60 percent of the system is equipped with radio-read metering (Sensus).
Except for a drought in 2006, water supply has not been an issue in Daphne, where average rainfall exceeds 64 inches per year. What had been an issue was production capacity — adequate wells and treatment to
meet demand. For years, the utility struggled to meet demand in summer and often saw every well pump running 24 hours a day for months just to keep up. Without redundancy, any equipment issue created an immediate water shortage somewhere in the system.
The utility remedied that over time with a $6 million capital con-struction program, which included three new wells and the new treat-ment facility.
Best practices
As straightforward as the water system is, the management program behind it is deep and comprehensive, reflecting the philosophy and com-mitment of the Daphne team. McElroy, Lyndall and English follow a

Systemwide, treated water passes through several 100,000-gallon clearwells and eventually to the 200-mile distribution system, mostly 6- to 16-inch PVC or ductile iron piping. Two booster pump stations are equipped with Gorman-Rupp pumps. High-service pumps were supplied by Peerless. Storage consists of seven above-ground tanks and one reser-voir. A SCADA system (Dexter Fortson Associates) provides automated monitoring and control. About 60 percent of the system is equipped with radio-read metering (Sensus).
Except for a drought in 2006, water supply has not been an issue in Daphne, where average rainfall exceeds 64 inches per year. What had been an issue was production capacity — adequate wells and treatment to
meet demand. For years, the utility struggled to meet demand in summer and often saw every well pump running 24 hours a day for months just to keep up. Without redundancy, any equipment issue created an immediate water shortage somewhere in the system.
The utility remedied that over time with a $6 million capital con-struction program, which included three new wells and the new treat-ment facility.
Best practices
As straightforward as the water system is, the management program behind it is deep and comprehensive, reflecting the philosophy and com-mitment of the Daphne team. McElroy, Lyndall and English follow a

structured process in which they envision what the utility wants to be for customers and employees, then give people the training, per-sonnel, support and equipment to realize the vision.
“We’re one utility. We win or lose together,” says McElroy. “In the eight years I’ve been here, we’ve never had a company meet-ing where we didn’t talk about that.” The key is what the Daphne team calls “seeing The Matrix,” an analogy drawn from the hit movie of that name.
The Matrix is simply the way things interconnect, much as
everything was interconnected in the film. Performance at the plant or in the distribution system relates to customer satisfaction. Customer satis-faction relates to customer support. Customer support enables proper funding of the utility, which in turn relates to the sustainability of service and performance.
Employees are crucial to success. “We try not to micromanage our staff,” McElroy says. Managers are directed to grant pay raises based solely on individual merit, not by seniority or through cost-of-living adjustments.
“We want to showcase the employees who are doing it right and that we’d like others to copy,” McElroy says. “Across-the-board pay raises don’t do that. We want our people to grow and succeed, and we encourage them to try things, learn things and risk failure in order to improve. We don’t want people worrying about making mistakes. We’re okay with the small mistakes as long as they help us to grow and evolve into something better.”
Conserving resources
The staff also stresses improvement, efficiency and innovation. “We hate to waste valuable resources anywhere in our system,” McElroy says. English points out that the utility often operates its wells at night to save on peak electric demand charges.
The utility has operated its own biodiesel plant since 2007, making fuel for its fleet and heavy equipment using used cooking oil turned in through a recycling program. The effort saves more than $10,000 a year on fuel. On the sewer side, a communitywide grease recycling program has helped the utility reduce sanitary sewer overflows by 70 percent since 2006.
McElroy believes these measures are evidence of another key to suc-cess — understanding the role of a small-town utility and knowing how to solve complicated problems in cost-effective ways. “We’re self-reliant and innovative,” he says. “A lot of the professional conferences we attend address issues typically from the perspective of a major city. They often showcase big, expensive solutions to really big problems that don’t always apply to small communities like ours. I don’t necessarily want advice

Customer service begins at the beginning. The utility greets each
new customer with a bag containing all sorts of information about the
utility, its services, where water comes from and how it’s treated, rates
and contact information, and various municipal fliers. The bag also
contains information about local businesses, organizations and services,
including maps, coupons and business cards.
“Your commercial customers are trying every way they know how to
get this information in the hands of potential customers,” says McElroy.
“You can help them be successful in this way and endear yourself to
them while helping your new customers.”
Customer Appreciation Days occur several times a year. Team
members set up tents, roll out the grills and serve hotdogs and bever-
ages. “We have our employees wash the cars of every single customer
who comes to the office that day,” says McElroy. “Some of our customers
come and hang out with us for hours. Our employees don’t just wash
cars. We prep them all carefully. We remind them, department by
department and team by team, that these customers are the ones who
fund their paychecks.”
The customer service program aims to impress and educate
ratepayers, from courteous phone service (“Pretend it’s your grand-
mother calling,” says McElroy) to the cleanliness of the office bathrooms,
to simply smiling and saying hello.
McElroy and team members Danny Lyndall and Larry English have
presented the customer service program at numerous conferences and
in several publications. They stress that while public utilities do not have
competition, they do compete for a share of customers’ budgets.
“We need to shoot straight with our customers — let them know the
value of water,” says McElroy. “Customers don’t make up stories about
you and your company. They simply repeat the stories you tell them
through your words and actions. If you want remarkable things said
about your company, you have to do remarkable things that your
customers actually notice.”

Harnessing Water PowerMohawk Valley Water Authority uses hydroturbines to cut electric bills and generate income, while plant upgrades keep things running efficiently
BY LISA BALCERAK
Decades ago, the Mohawk Valley Water Authority (MVWA) used throttling valves in the drinking water transmission system to prevent excessive pressure down the line.
Seeing an opportunity to capture the power of water pres-sure and flow for electricity, MVWA installed two hydroturbines and a microturbine that provide revenue and savings that total $95,000 a year. The utility has also optimized its treatment plant to be more energy effi-cient, use less chemicals and produce less sludge.
MVWA, in Utica, N.Y., serves 130,000 people in 18 municipalities. The service area in the foothills of the Adirondack Mountains has eleva-tions that vary by up to 800 feet. Most of the 23 pressure zones have their own pump stations and water storage. The 373-square-mile Hinckley watershed, which provides the water supply, is mostly within Adirondack Park. MVWA has rights to withdraw up to 48.5 mgd from the 25-billion-gallon Hinckley Reservoir, owned by the New York State Canal Corpora-
tion. The utility’s 30 storage tanks hold 60 million gallons.
MVWA’s water treatment plant (32 mgd capacity, 20 mgd average) uses conventional coagulation, clarification and filtration. Following U.S. EPA requirements for disinfection byprod-ucts, the authority installed granular
activated carbon (GAC) filter media in its four filter beds and is pilot-test-ing in-situ carbon regeneration methods.
MVWA has a staff of 90 and an in-house EPA-certified lab that does contract work for other area utilities. The annual budget for treatment and distribution is $21 million.
Generating power
While designing a new treatment plant in 1992, MVWA knew that microturbines were a logical addition. “When we throttled to relieve water pressure, we were wasting energy,” says Dick Goodney, P.E., direc-tor of engineering. “It made sense as part of the treatment plant to pro-vide some type of energy recovery mechanism, and hydroturbines were the best option.”
Two Byron Jackson hydroturbines (Flowserve) now provide 450 kW of capacity. An upstream turbine in the treatment plant basement controls the raw water flow and pressures into the chemical contact basins. The downstream turbine is several miles from the plant on the finished water line that runs to the distribution system. MVWA earns $80,000 in reve-nue annually from these two units by selling hydroturbine power to the local utility, National Grid.

The upstream Byron Jackson hydroturbine (Flowserve) at the MVWA water treatment plant.
More powerSeeing the success of the hydroturbines, and understanding local
topography, utility staff contracted with the Wendel Duchscherer engi-neering company to study the feasibility of microturbines to capture more energy. The New York State Energy Research and Development Author-ity (NYSERDA) provided a $5,000 grant for this $10,000 research study.
The study identified several locations with potential for smaller in-line turbines, including the Deerfield Reservoir storage tank. A 25 kW turbine (Cornell Pump Co.) is now installed at the tank’s control building and is coupled to a centrifugal pump (Goulds). The microturbine energy powers the standby open reservoir’s water recirculation system, which pumps 2 mgd. By using the microturbine instead of grid power, MVWA
saves $15,000 annually, for a payback of less than five years.
In another initiative to enhance efficiency, MVWA has upgraded its treatment plant. Using funds from a National Grid incentive program, the utility last year replaced old fluores-cent lighting with LEDs in 40,000 square feet of administration and pro-
cess areas. Since the older lights were often slow to turn on, staff mem-bers often left them on even when spaces were unoccupied. The LEDs respond quickly and are only turned on when needed. Projected payback is five years.
To retain heat in the entire plant, MVWA replaced an old vinyl roof with an 18,000-square-foot single-membrane synthetic (EPDM) roof and added more insulation to meet state codes for R-value. Now, the facility costs less to heat and is more comfortable for employees.
Research partially funded by NYSERDA is underway to evaluate a
more efficient HVAC system for the maintenance facility. The 20,000-square-foot building now uses a 30-year-old gas-fired boiler. Study results are due in early 2014, and the changeover is planned for 2015.
Reducing residuals
MVWA also looked for ways to save on chemicals, reducing costs and limiting water treatment plant sludge production. Over the years, the utility has been optimizing processes to minimize chemicals used for coagulation (alum) and pH adjustment (lime and soda ash). MVWA con-tinuously tests incoming water and adjusts chemical dosages.
“We want to minimize chemical use because everything we add to the water eventually comes out in backwash sludge,” Goodney says. “By add-ing fewer solids in the form of chemicals, we have less sludge to handle.
“What’s most important for us is performance. We have to provide reliable water into our system. But looking at sustainability and energy efficiency, most of the time, they complement the perfor-mance improvements. When we can get a better, more efficient workplace that’s sustainable, it just makes sense.” wso

14 WATER SYSTEM OPERATOR
STORY: TRUDE WITHAMPHOTOGRAPHY: DAVID MAKKERS
Operators at the Frank C. Amerson Jr. Water Treatment Plant have found that being proactive reaps rewards. So does providing valuable input that can improve plant operations.
“We have five committees at the plant, including an awards committee, and each operator takes part in one of these,” says Gary McCoy, director of water treatment for the Macon (Ga.) Water Authority. “The operators know the plant and go through every single building to make sure all the equipment is on the maintenance schedule and in good working order.”
Mock plant inspections and diligent follow-up correct any problems. Experience also helps. With more than 100 collective years in operations, the staff does it all, including lab work, routine maintenance and customer service.
A new plant in 2000 exposed operators to different filtration technology and sludge handling equipment. Diligent training and mock equipment startups brought them up to speed. Other challenges include getting just the right chemistry to treat the lake water, and preparing for award competitions.
“Some of our operators have six months’ experience and some have much more, but they check their egos at the door and work together to make each other bet-ter. This is why we are successful,” says McCoy. This success is reflected in awards, including Plant of the Year and the Gold Award for 100 percent compliance from the Georgia Association of Water Professionals (GAWP) in 2012. It was the facility’s fourth Plant of the Year award for surface water plants with greater than 50 mgd capacity, and its eighth Gold award.
“These awards serve to motivate and help the staff to be better operators,” says McCoy. “If they don’t win an award, they mope around like their spouse just left them.”
Better processMacon Water Authority owns the 60 mgd Amerson
conventional treatment plant along with the Rocky Creek and Lower Poplar Street Water Reclamation Facilities. The authority’s division of water operations also oversees 75 acres of wetlands on plant property.
The Amerson facility, built beside the newly con-structed 5.8-billion-gallon Town Creek Reservoir (now named Javors J. Lucas Lake), replaced a cen-tury-old water treatment plant that was heavily dam-aged in a 1994 flood. The city-owned lake and 3,000 acre buffer were built to meet future needs.

PLANTThe new Frank C. Amerson Jr. plant (construction work shown in progress at the Javos J. Lucas Lake basins) exposed the team to new filtration and sludge-handling technology.
16 WATER SYSTEM OPERATOR
Ocmulgee River water is pumped to the lake, which provides up to a five-month supply, and then to the Amerson plant for treat-ment with lime, chlorine dioxide, alum, potassium permanganate, granular activated carbon (GAC), chlorine, fluoride and phosphate. An additional booster pumping station connects the river intake and the Amerson plant, bypassing the lake. This alternative raw water pumping method allows continuous operation during maintenance or in case of emergencies.
Operators trained for six months on the Amerson plant equipment. The solids press building, high-ser-vice pumps, Wonderware SCADA software (Invensys), Leopold Clari-Vac floating sludge collector (Xylem) and generators were all new to them. The team conducted mock startups to make sure operators were com-fortable with the equipment.
The new plant offered many improvements. “The old plant had steam-operated turbines and boiler,” says McCoy. “We now have vari-able-frequency drive pumps that automatically ramp up and down according to system demand.”
GAC filters replaced anthracite media, and plate presses replaced sludge drying beds. “Our GAC fil-ters are top-of-the-line, and great for organics removal,” McCoy says. “We don’t have a problem with dis-infection byproducts, since the filters remove most of the organics that can interact with the chlorine to form DBPs, such as trihalomethanes.” The process adds lime to the solids to raise the pH before dewatering. Sol-ids are collected by Macon Soils, a Macon Water subsidiary, and distrib-uted to farmers.
Versatile team
Twelve operations staff keep the Amerson plant running smoothly. They report to McCoy, who holds a Class I operator license and has been with Macon Water for 10 years. He reports to executive director Tony Rojas. Team members include:
• Jocelyn Hunt, assistant plant manager, Class I, 21 years at the plant
• Sylvia McCrary, laboratory supervisor, water laboratory license, 25 years
• William Brown (20-plus years), Dale Moorehead (20-plus years) and Chuck Mixon (11 years), Class I operators
• Lisa Horne (eight years), Ronnie Evans (seven years) and Bill Maine (seven years), Class II operators
• Adrian Ashley, Class III operator, (one year)• David Smith, Adrian Stokes and Randal Cole, trainees The plant is staffed around the clock with an inside and outside oper-
ator on each shift. The inside operator conducts lab tests, monitors the SCADA system and handles customer service complaints. The outside operator conducts plant checks every two hours, backwashes the filters
and runs the Clari-Vac system and filter presses.
Operators perform routine equipment maintenance and com-municate to centralized mainte-nance staff and the buildings and grounds crew what needs to be done to maintain the buildings, 19 tanks and 57 lift stations.
Routine lab tests include tur-bidity, iron and manganese, hard-ness, alkalinity, chlorine, chlorine

dioxide, chlorite, aluminum, fluoride, pH and phosphate. Operators use Hach turbidimeters, spectrophotometers and chlorine dioxide analyzers, and a Denver pH meter. Most lab tests are run every hour, and a few every two hours, to make sure the plant is producing consistent-quality water.
Treating the lake water can be a challenge. “We perform a daily jar test to optimize the correct chemical dosage that’s required to best treat the water,” says McCoy. “With the low turbidity in the lake, we some-times have to use polymer as a weighting agent to eliminate the fine sus-
pended particles that will not settle. We use chlorine dioxide to oxidize iron and manganese to prevent taste and odor problems.”
Since the plant serves as an administrative facility after hours, operators are responsible for cus-tomer service after 7 p.m. and on weekends and holidays. This includes sending on-call person-nel to restore water service, dis-
patching field service and line maintenance crews, handling water complaints and writing work orders for water main repairs.
Staying proactive
Preparing for the Plant of the Year award competition kept the operators on their toes. “We won the first award in 2002, but we’re only eligible every other year,” says McCoy. “We won every time except twice. We’re judged in the large systems category, so there’s a lot of competition, like the city of Atlanta, Gwinette County, Colum-bus Water Works, Dekalb County and other large utilities.
“My administrative assistant, Janice Wright, is a detail-oriented person, so I asked her to assist in conducting mock plant inspections, which the operators took very seri-ously. We graded the plant and the operators’ performance and let them know how they could improve on their overall knowledge and also correct plant weaknesses.”
McCoy assigned three opera-tors to the operations committee, which met monthly and sent him reports. The members provided valuable feedback, such as suggesting changes in feed rates to improve turbidity removal. Operators inspected everything from lab chemical expiration dates to backflow preventers.
“Being proactive is what this committee was all about,” says McCoy. “Of course, our main job is to produce a quality product, and we’re very fortunate to have a water board that provides us with the necessary tools
GIVING BACK
Gary McCoy has devoted most of his life to water treatment. As director of water treatment for the Macon
(Ga.) Water Authority, he worked his way up through the ranks. His success came from hard work, networking with
peers and tirelessly volunteering on various committees.
“I started as a janitor in my hometown at the City of Cartersville water plant,” he says. “I noticed that the
operators were making good money — a lot more than I was — so I asked for an opportunity to train as an
operator, became certified and was hired.” McCoy has won many awards:
• Top Operator, Georgia Association of Water Professionals (GAWP), 1998.
• Operator Meritorious Service Award, AWWA Georgia Section, 1999.
• Elizabeth McEntire Award for outstanding service to GAWP, 2003.
• AWWA George Warren Fuller for distinguished service to the water field, 2009.
• GAWP Nathan M. DeJarnette Award for accomplishments in facility operations, 2009.
• William J. Greene, Jr. Award for outstanding service to Georgia AWWA, 2010.“I won these awards because I have a great relationship with my peers in the industry,” says McCoy. “I started
volunteering in different areas, including GAWP’s Distributor of the Year Committee. Volunteering is how I give back.”
He was elected to the GAWP 5S Society in 2004 for volunteering to promote scholarships on behalf of the
association. In 2009, he chaired the GAWWA, and in 2010 he was elected for a three-year term on the national
AWWA Board of Directors. He attends other AWWA state conferences and speaks on behalf of the national AWWA.
McCoy considers the industry’s future: “I serve on the AWWA Diversity and Inclusion Committee, where I help
ensure that the industry stays diverse. I’m also concerned about infrastructure. An AWWA study, ‘Buried No Longer,’
found that in the next 25 years, it will take more than a trillion dollars to upgrade water system infrastructure.”
Recently, McCoy and 60 AWWA members attended the association’s annual Washington, D.C. Fly-in to lobby
their legislators. They asked Congress members to support the Water Resources Development Act of 2013, which
included a Water Infrastructure Finance and Innovation Authority pilot program that would make low-interest loans
for large water infrastructure projects.
“In June 2013, the Senate passed the pilot program to move this through,” McCoy says. My colleagues and I
are proud to have helped this come to pass.”

Motivated operators
The operators train and moti-vate each other, says McCoy, whether discussing the merits of a particular plant adjustment at a monthly staff meeting, or helping each other train for state certifica-tion exams. After attending a con-ference, they suggest different approaches to tasks and apply what they have learned to improve operations.
Operations and maintenance staff worked together on a project to keep leaves from plugging the intake bar screen. They installed a device to deflect the leaves downriver and regularly wash down the screen to prevent leaves from sticking to the bars. McCoy sets the plant’s operating parameters but lets operators make

McCoy doesn’t foresee a need for upgrades: “We have lots of capacity, and in fact we’re averaging only 25 mgd now. But by 2016 we may see more stringent regulations, such as the new coliform and THM regula-tions that will make it necessary to change our method of operation.”
The plan is to continue with community outreach and environmental activities. “We have an open house during AWWA National Drinking Water Week and conduct tours throughout the year,” McCoy says. “We speak at various public meetings when requested and participate in career days at area schools.”
During the open house, the public can learn about drinking water production while touring the plant. They also learn how Macon Water works to protect the community’s water supply and natural resources. Hunt assists with annual river clean up, moni-tors solids that are returned to the river and creates source water pro-tection plans.
McCoy and his staff plan to continue pursuing awards, which motivate staff and encourage them to improve plant operations. His advice to other plant managers: Allow operators to visit other plants for new ideas and, if the budget allows, have them attend local confer-ences for networking. “Be proactive,” he says. “Get your operators involved and keep them abreast of what’s going on. They are your eyes and ears of plant operations. Become more hands on, and you will be successful.” wso

The operator of a small water system asked about an alternative dis-infectant to chlorine. The community was interested in an economi-cally feasible choice because the U.S. EPA Phase 2 Disinfectant and Disinfection Byproducts Rule was about to take effect.
The aquifer in southeast coastal Georgia and northern Florida has elevated organics levels, and chlorine disinfection can lead to the forma-tion of trihalomethane contamination. We told the operator that increas-ingly, over the past decade, it has been challenging to produce safe, clean drinking water.
Outbreaks of water-borne diseases in the United States and Canada have made people aware that water contaminated with microorganisms can cause serious illness or even death. The challenges posed by contam-inated water are more common in the developing world, but there are growing indications that industrialized countries have not managed their water resources properly.
We also noted that confidence in the ability to protect human health from contaminated drinking water has been eroded by questions about the safety and effectiveness of traditional chlorine disinfection.
The role of UVChlorine-resistant pathogens and concerns about potentially cancer-
causing disinfection byproducts (DBPs) from chlorine treatment have led to new EPA guidelines that require municipalities to eliminate or reduce chlorine usage. We pointed out that ultraviolet (UV) light disinfection has become an answer.
UV treatment has been used in Europe and North America for decades. The first applications were in France starting in 1910. UV tech-nology is a highly effective, cost-efficient and proven way to destroy micropollutants and microorganisms. It has earned the confidence of thousands of municipalities for disinfecting wastewater, drinking water and industrial process waters.
The UV light spectrum lies between the shortest wavelength of light visible to the human eye, and X-rays, which of course are invisible. Spe-cific wavelengths within this band of the light spectrum are character-ized as germicidal. Water treatment systems use a UV light source with a protective covering (usually a watertight quartz sleeve) immersed in water to be treated.
The UV rays emitted by the lamp inactivate harmful microorganisms and parasites. As the water rushes by the lamps, microorganisms are exposed to a lethal dose of UV energy. The rays alter the DNA of para-sites, yeasts, molds, algae, bacteria and viruses, so that even though they are technically still alive, they cannot reproduce, are powerless to infect a host and are considered inactivated. The process has a 4-log effectiveness, which means it destroys 99.99 percent of the target organisms.
Clear benefits
Among its advantages, UV disinfection is safe and environmentally friendly — there are no chemicals for system operators to handle and no potential for chemical releases to the environment. UV leaves no smell or taste in the treated water, and in fact the process can improve the water’s taste by destroying organic contaminants.
We told the community’s operator that UV treatment should be used in combination with other forms of disinfection and filtration. UV sys-tems in drinking water are most commonly used as a secondary treat-ment process and as a primary disinfectant. They are not intended to treat water that is visually contaminated, and they cannot convert waste-
water to safe, potable water. UV technology is endorsed by the EPA. It destroys
bacteria such as E. coli, viruses like those that cause hepatitis and polio, and virtually all other waterborne pathogens. This includes Cryptosporidium and Giardia parasites, which are resistant to chlorine disinfection. UV also eliminates harmful micropollutants such as
herbicides and pesticides. It works at least 20 times as fast as chlorine and is more cost-effective.
Future potential
Looking ahead, solar water disinfection has been comprehensively researched in Switzerland, and scientists have proven that natural sun-light can effectively treat small volumes of water inexpensively. In this process, contaminated water is poured into transparent plastic bottles, and the bottles of water are exposed to full sunlight for six hours.
The sunlight treats the contaminated water through two synergetic pathways. First, UV-A radiation damages the DNA of organisms present in the water, and second, the process raises the water’s temperature, dam-aging the proteins in pathogenic organisms. If the water’s temperature rises above 120 degrees F, the disinfection process occurs three times faster.

The operator of a small water system asked about an alternative dis-infectant to chlorine. The community was interested in an economi-cally feasible choice because the U.S. EPA Phase 2 Disinfectant and Disinfection Byproducts Rule was about to take effect.
The aquifer in southeast coastal Georgia and northern Florida has elevated organics levels, and chlorine disinfection can lead to the forma-tion of trihalomethane contamination. We told the operator that increas-ingly, over the past decade, it has been challenging to produce safe, clean drinking water.
Outbreaks of water-borne diseases in the United States and Canada have made people aware that water contaminated with microorganisms can cause serious illness or even death. The challenges posed by contam-inated water are more common in the developing world, but there are growing indications that industrialized countries have not managed their water resources properly.
We also noted that confidence in the ability to protect human health from contaminated drinking water has been eroded by questions about the safety and effectiveness of traditional chlorine disinfection.
The role of UVChlorine-resistant pathogens and concerns about potentially cancer-
causing disinfection byproducts (DBPs) from chlorine treatment have led to new EPA guidelines that require municipalities to eliminate or reduce chlorine usage. We pointed out that ultraviolet (UV) light disinfection has become an answer.
UV treatment has been used in Europe and North America for decades. The first applications were in France starting in 1910. UV tech-nology is a highly effective, cost-efficient and proven way to destroy micropollutants and microorganisms. It has earned the confidence of thousands of municipalities for disinfecting wastewater, drinking water and industrial process waters.
The UV light spectrum lies between the shortest wavelength of light visible to the human eye, and X-rays, which of course are invisible. Spe-cific wavelengths within this band of the light spectrum are character-ized as germicidal. Water treatment systems use a UV light source with a protective covering (usually a watertight quartz sleeve) immersed in water to be treated.
The UV rays emitted by the lamp inactivate harmful microorganisms and parasites. As the water rushes by the lamps, microorganisms are exposed to a lethal dose of UV energy. The rays alter the DNA of para-sites, yeasts, molds, algae, bacteria and viruses, so that even though they are technically still alive, they cannot reproduce, are powerless to infect a host and are considered inactivated. The process has a 4-log effectiveness, which means it destroys 99.99 percent of the target organisms.
Clear benefits
Among its advantages, UV disinfection is safe and environmentally friendly — there are no chemicals for system operators to handle and no potential for chemical releases to the environment. UV leaves no smell or taste in the treated water, and in fact the process can improve the water’s taste by destroying organic contaminants.
We told the community’s operator that UV treatment should be used in combination with other forms of disinfection and filtration. UV sys-tems in drinking water are most commonly used as a secondary treat-ment process and as a primary disinfectant. They are not intended to treat water that is visually contaminated, and they cannot convert waste-
water to safe, potable water. UV technology is endorsed by the EPA. It destroys
bacteria such as E. coli, viruses like those that cause hepatitis and polio, and virtually all other waterborne pathogens. This includes Cryptosporidium and Giardia parasites, which are resistant to chlorine disinfection. UV also eliminates harmful micropollutants such as
herbicides and pesticides. It works at least 20 times as fast as chlorine and is more cost-effective.
Future potential
Looking ahead, solar water disinfection has been comprehensively researched in Switzerland, and scientists have proven that natural sun-light can effectively treat small volumes of water inexpensively. In this process, contaminated water is poured into transparent plastic bottles, and the bottles of water are exposed to full sunlight for six hours.
The sunlight treats the contaminated water through two synergetic pathways. First, UV-A radiation damages the DNA of organisms present in the water, and second, the process raises the water’s temperature, dam-aging the proteins in pathogenic organisms. If the water’s temperature rises above 120 degrees F, the disinfection process occurs three times faster.

20 WATER SYSTEM OPERATOR
Water tank inspection can be a costly process, often requiring tanks to be drained and taken out of service. Finished water is wasted and service to customers can be disrupted.
Aquabotix Technology Corp. has developed an alterna-tive in a robotic inspection system that can be sterilized, inserted into the tank and driven around using computerized controls. It’s the same basic concept as in video pipe inspection cameras, except that this system oper-ates in three dimensions instead of on a linear course. One version of the device includes rotating brushes that can actually scrub deposits off the tank walls.
Durval Tavares, company president, worked 20 years on underwater technology with the Naval Undersea Warfare Center in Newport, R.I. After a career change to the financial sector, he returned to his roots in the water business, aiming to develop products that would make a differ-ence in people’s lives. That includes making work life easier for people who inspect potable water tanks.
“Being able to see the condition of those tanks helps water authorities extend tank life and provide higher-quality water service to consumers,” Tavares said. He talked about the Aquabotix technology in an interview with Water System Operator.
wso: Without this technology, how are water tanks inspected?Tavares: One way is to empty the tank and have people enter through
a hatch and check it out. The problem is you have to shut off the water supply from that tank while you do the inspection. You also waste a lot of water by dumping it so you can do the inspection.
Another way is to put a diver into the tank. That can be a costly and complicated process because you’re putting a human being inside the fresh water supply. The person doing the inspection and the equipment have to be bathed in a disinfectant solution. You’re also putting the diver at risk because inside these tanks it’s easy to lose track of where you are.
It looks the same everywhere you go.

wso: What are the specific advantages of your approach to inspections?
Tavares: Our vehicles record exactly what the inside of the tank looks like so that the water authority can make decisions on good infor-mation. There are no lubricants and no other pollutants on the vehicle. It’s made of metal and ABS plastic. We recommend that the vehicle be doused in a chlorine solution before placing it in the tank so they don’t risk contaminating the water.
wso: Please describe how these vehicles work.Tavares: We make two vehicles for water tank inspections – an entry-
level HydroView Inspector and a higher-end HydroView Professional. Both can go down to 250 feet. They come with two cameras, one in front and the other mounted on top of the vehicle. That second camera can be aimed in any direction. You can swim the vehicle along the inside of a tank, and as you do that you can have the top-mounted camera facing at 90 degrees to the travel direction, so you can record the condition of the wall as you travel around.
Both models record high-definition digital video and high-definition still images on an internal memory. After the inspection you can go back, review the recording and select the pictures to include in a report. The vehicles have depth sensors, temperature sensors and heading sensors that tell you the direction of travel, as with a compass. They come with an internal LED light, and 800 lumens of external LED lighting can be added.
wso: What is the method of propulsion and steering?Tavares: The Inspector model has three high-precision Swiss-made
motors. A rear propeller lets you control the pitch of the vehicle, and two front propellers let you control forward/backward motion and turning.
The Professional model has eight motors. Three are dedicated to hovering and one controls lateral movement. For the remaining four
motors, you have all four control forward/backward movement, or have two for forward and back and put brushes on the other two. Then if you see a buildup on the tank wall, you can have the brushes scrape it off so you can inspect and see what is underneath. The motors spin at up to 3,000 rpm. One rotates clockwise and the other counterclockwise. If they both turned in the same direction, the vehicle would walk the wall and you would lose control.
wso: What is the power source for the vehicles?Tavares: They are powered by built-in lithium-ion batteries that are
fully sealed. Battery life is two to three hours, which is plenty of time to complete a tank inspection.
wso: How does the inspection operator control the vehicle?Tavares: They need to be tethered because Wi-Fi and radio signals
will not travel through water. The vehicles can pull a cable length up to 500 feet. The cable can extend from the ground to the top of the tank and into the tank. A person standing on the ground can control the vehicle.
The operator can use a PC and a game-console-type control box with joy-sticks, or control the vehicle with an iPad. In that case, they can actually turn the vehicle left and right, up and down, by turning the iPad.
wso: What has been the market’s reaction to this technology?Tavares: There has been a lot of interest. We’ve delivered several to
water authorities, and we’ve had contractors who do water tank inspec-tions purchase them. Tank inspection companies find that they can pro-vide a better service to customers because they can do the job quicker and with less impact on the customer’s operations.
wso: Does it take a large water utility to justify the purchase of
a vehicle?Tavares: No. A tank inspection typically costs $1,500 and up. If you
inspect 10 tanks, you have essentially paid for a HydroView Professional right there.
wso: What other applications does this technology have?Tavares: It can be used to inspect water intakes for water treatment
plants and the water intakes and outlets for power plant cooling systems. Otherwise it can be used for anything from marine craft inspection, to search and recovery efforts, to inspecting tanks in aquaculture. wso

UrbanRENEWalMiddlesex Water works underground to update its water distribution infrastructure, reduce leakage and improve customer service
STORY: JIM FORCEPHOTOGRAPHY: JEFFREY HERRING
A section of 6-inch cast iron pipe, circa 1900, being replaced in South Amboy, N.J.
In the nationwide campaign to improve municipal infrastructure, the Middlesex Water Company is pulling its weight. Just last September, the company wrapped up the latest project in a 20-year program to rehabilitate water mains, service lines and hydrants throughout areas of New Jersey where it provides water services. In South Amboy, the company spent some $4 million to clean and line
11,900 linear feet of 6- to 8-inch water main, enlarge another 9,000 feet of main from 4 to 8 inches, and replace 31 hydrant assemblies and 475 water service lines.
The project, called RENEW, is meant to bring aging water lines up to modern standards and ensure service for the full lifetime of the pipe, according to Richard M. Risoldi, vice president and chief operating officer.
The company, which owns and operates water utility and waste-water systems in New Jersey, Del-aware and Pennsylvania, upgraded a portion of South Amboy’s water lines in 2011. The recent work is a continuation of a planned upgrade to the company’s 730-mile water distribution system.
“Rehabilitation of mains, rather than more costly replacement, is often the most viable solution, helping to restore the original use-ful life of older pipe while main-taining operating costs,” says Risoldi. “The RENEW program translates into less lost water through leaks, and enhanced water quality and pressures for our cus-tomers.” Funding for the project has come from the New Jersey State Revolving Loan Fund.
Well connected
Headquartered in Iselin, N.J., publicly traded Middlesex Water was incorporated in 1897. Its work-force numbers more than 270. In Middlesex County, the company serves more than 60,000 retail cus-tomers, including about 2,200 in South Amboy. Raw water for about 75 percent of the service area is drawn from the Delaware and Rar-itan Canal. It is treated with con-ventional disinfection, coagulation, filtration and post-chlorination at the 55 mgd Carl. J. Olsen Surface Water Treatment Facility, named for the company’s fourth president.
The rest of the area is served from four wellfields containing 31
wells in the northern part of the service territory. Four small treatment plants disinfect the groundwater before distribution. The largest plant uses air stripping to remove volatile organic compounds. The company purchases 3 mgd from a neighboring utility.
The Middlesex County operation includes 24 million gallons of stor-age. Seven million gallons flow by gravity from an elevated storage tank, and the remainder is pumped from above-ground storage facilities into the distribution system. The system is managed through a state-of-the-art enterprise resource planning (ERP) system (Oracle) connected to a geographic information system (Esri) and a Water GEMS hydraulic model (Bentley). The ERP system includes mobile workforce management.
This technology “connects all the dots,” according to Risoldi: “Our mobile workforce management system is connected via our ERP system to customer service. As our staff is made aware of a problem, an electronic activity form is filled out and sent wirelessly to our field people, who investigate the issue and make the necessary repairs. The information on the repairs is sent back to customer service and made part of the customer record.

“Dispatchers watch the mobile application in real time. They can see the trucks moving and view all of the outstanding work routed to our mobile personnel. It has improved our response time and personal pro-ductivity. It’s very efficient.” The SCADA system uses Wonderware (Invensys) as the operator interface software.
The Middlesex Water team performs all routine maintenance on valves, small mains and hydrants. Other work, including annual leak surveys in specific sections of the system, has traditionally been contracted out. How-ever, the company is now implementing its own leak detection system.
South Amboy renewal
The RENEW project in South Amboy included water mains in a spe-cific area targeted through analysis of water quality and load and pres-sure data, dating back several years. To clean and line the old 6- and 8-inch mains, the lines were first scraped with an abrasive rotary tool and
then flushed. “These were old unlined vintage pipes consisting of bare iron,” says Brian Carr, senior project engineer. “Water causes oxidation and mineral deposit that restricts the inside diameter, by up to half in some cases.”
The aim was to remove the mineral deposits, restore the original diam-eter, and then trowel a 1/16-inch coating of cement on the inside walls, so
that the iron would no longer come in contact with the water. “We worked with 600-foot sections,” Carr says. “We disconnect the sec-tion and supply water temporarily to the customer through a bypass
pipe that lies on the ground and is disinfected and properly marked for safety reasons.”
The customers are on the bypass system for an average of three weeks. They have water continuously except for the few minutes it takes to con-nect and disconnect the bypass piping. Temporary hydrants are installed to maintain fire protection. The company’s cleaning and lining contrac-tor took video images of the piping before and after the repairs. Company officials inspected and approved the work. The oxidized material removed from the sections was collected and landfilled.
Improving service
In other parts of the South Amboy system, 4-inch pipe was replaced with 8-inch pipe, laid in an open trench next to the old lines. The new pipe is cement-lined ductile iron. Concurrent with main cleaning and enlargement, the RENEW project renewed service lines to some 475 cus-
BATTENING DOWN THE HATCHESIt’s an accident of geography, but one of the biggest challenges
faced by Middlesex Water Company is its location along the East Coast,
an area prone to damaging floods and storms in recent years. In
dealing with such events, the company’s emergency response and
diverse geographic structure have helped significantly.
Bernadette M. Sohler, vice president of corporate affairs, says the
company has a fully integrated emergency management team, with
coordinators in each of seven regional companies.
“They are connected as part of a single incident command
structure,” she says. “They report and manage developments, coordi-
nate activity and leverage assets, shuttling human resources and
equipment around as needed.”
During Superstorm Sandy in October 2012, all power was out and
refineries were shut down in the company’s New Jersey service area,
resulting in a diesel fuel shortage. The emergency team obtained fuel
from its subsidiary in Delaware, which was less affected by the storm. The
fuel was needed to power company facilities, which were on emer-
gency generators for an extended time.
“We’re located in the path of storm surges and hurricanes,” says Sohler.
“Emergency preparedness is a big deal and one of our highest priorities.”
The company has constantly revisited and adjusted its plans as
storms have become more widespread, more frequent and longer-last-
ing. In such emergencies, Middlesex Water assists other area water and
wastewater utilities.
“We work to maintain relationships with the municipalities we serve,
our wholesale customers and the state emergency response team
throughout the year,” says Sohler. “We communicate constantly during
emergencies. We want to serve as a resource wherever we are needed.”
Shane Inman, left, construction foreman, and Gary Colfer, construction inspector, oversee the installation of new 8-inch ductile composite iron pipe in South Amboy as part of the RENEW program.
“People are concerned about a project that is a bit disruptive like this. We did a lot of public education before the project started, meeting with
the town council and meeting with the people who were affected.”BRIAN CARR
tomers and replaced 31 hydrants. “The old service lines were
galvanized for the most part, with some plastic, and were in bad shape,” says Carr. The new lines are all copper. The work required service technicians to enter homes to pull meters and clean the service lines. That took a strong public educa-tion effort on the front end.
“People are concerned about a project that is a bit disruptive like this,” says Carr. “We did a lot of public education before the proj-ect started, meeting with the town council and meeting with the people who were affected. We issued press releases, sent letters, posted information to our website and over social media, and even created a short video to educate customers about the project, the process and how it ultimately would benefit them.”
The biggest issue was getting the town and customers comfortable with the project — to see that short-term inconvenience translated to long-term value. “You’re dealing with people who are not used to this,” Carr says. While the latest work wrapped up in November, Middlesex Water plans to resume the RENEW program next spring. “We’ve done about 85 miles of cleaning and lining to date and have 125 miles left to do,” says Carr.
Life extension And while that will help restore the useful life of the piping serving

“Dispatchers watch the mobile application in real time. They can see the trucks moving and view all of the outstanding work routed to our mobile personnel. It has improved our response time and personal pro-ductivity. It’s very efficient.” The SCADA system uses Wonderware (Invensys) as the operator interface software.
The Middlesex Water team performs all routine maintenance on valves, small mains and hydrants. Other work, including annual leak surveys in specific sections of the system, has traditionally been contracted out. How-ever, the company is now implementing its own leak detection system.
South Amboy renewal
The RENEW project in South Amboy included water mains in a spe-cific area targeted through analysis of water quality and load and pres-sure data, dating back several years. To clean and line the old 6- and 8-inch mains, the lines were first scraped with an abrasive rotary tool and
then flushed. “These were old unlined vintage pipes consisting of bare iron,” says Brian Carr, senior project engineer. “Water causes oxidation and mineral deposit that restricts the inside diameter, by up to half in some cases.”
The aim was to remove the mineral deposits, restore the original diam-eter, and then trowel a 1/16-inch coating of cement on the inside walls, so
that the iron would no longer come in contact with the water. “We worked with 600-foot sections,” Carr says. “We disconnect the sec-tion and supply water temporarily to the customer through a bypass
pipe that lies on the ground and is disinfected and properly marked for safety reasons.”
The customers are on the bypass system for an average of three weeks. They have water continuously except for the few minutes it takes to con-nect and disconnect the bypass piping. Temporary hydrants are installed to maintain fire protection. The company’s cleaning and lining contrac-tor took video images of the piping before and after the repairs. Company officials inspected and approved the work. The oxidized material removed from the sections was collected and landfilled.
Improving service
In other parts of the South Amboy system, 4-inch pipe was replaced with 8-inch pipe, laid in an open trench next to the old lines. The new pipe is cement-lined ductile iron. Concurrent with main cleaning and enlargement, the RENEW project renewed service lines to some 475 cus-
BATTENING DOWN THE HATCHESIt’s an accident of geography, but one of the biggest challenges
faced by Middlesex Water Company is its location along the East Coast,
an area prone to damaging floods and storms in recent years. In
dealing with such events, the company’s emergency response and
diverse geographic structure have helped significantly.
Bernadette M. Sohler, vice president of corporate affairs, says the
company has a fully integrated emergency management team, with
coordinators in each of seven regional companies.
“They are connected as part of a single incident command
structure,” she says. “They report and manage developments, coordi-
nate activity and leverage assets, shuttling human resources and
equipment around as needed.”
During Superstorm Sandy in October 2012, all power was out and
refineries were shut down in the company’s New Jersey service area,
resulting in a diesel fuel shortage. The emergency team obtained fuel
from its subsidiary in Delaware, which was less affected by the storm. The
fuel was needed to power company facilities, which were on emer-
gency generators for an extended time.
“We’re located in the path of storm surges and hurricanes,” says Sohler.
“Emergency preparedness is a big deal and one of our highest priorities.”
The company has constantly revisited and adjusted its plans as
storms have become more widespread, more frequent and longer-last-
ing. In such emergencies, Middlesex Water assists other area water and
wastewater utilities.
“We work to maintain relationships with the municipalities we serve,
our wholesale customers and the state emergency response team
throughout the year,” says Sohler. “We communicate constantly during
emergencies. We want to serve as a resource wherever we are needed.”
Shane Inman, left, construction foreman, and Gary Colfer, construction inspector, oversee the installation of new 8-inch ductile composite iron pipe in South Amboy as part of the RENEW program.
“People are concerned about a project that is a bit disruptive like this. We did a lot of public education before the project started, meeting with
the town council and meeting with the people who were affected.”BRIAN CARR
tomers and replaced 31 hydrants. “The old service lines were
galvanized for the most part, with some plastic, and were in bad shape,” says Carr. The new lines are all copper. The work required service technicians to enter homes to pull meters and clean the service lines. That took a strong public educa-tion effort on the front end.
“People are concerned about a project that is a bit disruptive like this,” says Carr. “We did a lot of public education before the proj-ect started, meeting with the town council and meeting with the people who were affected. We issued press releases, sent letters, posted information to our website and over social media, and even created a short video to educate customers about the project, the process and how it ultimately would benefit them.”
The biggest issue was getting the town and customers comfortable with the project — to see that short-term inconvenience translated to long-term value. “You’re dealing with people who are not used to this,” Carr says. While the latest work wrapped up in November, Middlesex Water plans to resume the RENEW program next spring. “We’ve done about 85 miles of cleaning and lining to date and have 125 miles left to do,” says Carr.
Life extension And while that will help restore the useful life of the piping serving
the citizens of this Central Jersey area, it’s only the beginning, as far as Middlesex Water is concerned. “We’re restoring the mains so they can carry water, but these pipes are aging,” says Risoldi. “We’re seriously thinking about the use of materials that will not just bring back the nor-

W hen is the last time someone asked you how much water it took to manufacture
the chair you sit on? Or the cheese you enjoyed on your sandwich?
These are a few of the ques-tions water utility staff members in Wyoming, Mich., pose to tour groups. The goal is to emphasize how water helps communities thrive and the importance of clean water to economic growth. It’s part of a public education that reaches multiple levels, from third grade to college graduates and beyond.
Two decades education Wyoming (population 73,000),
the largest suburb of Grand Rap-ids, lies in what was once known as the Manufacturing Belt. In 1966, the city began sourcing its water from the Lake Michigan Water Supply System, but busi-ness and population growth soon pushed demand beyond capacity. The system was expanded in 1973 and throughout the 1990s.
Wyoming’s first water and wastewater treatment plant tours 20 years ago were led by then-superintendent Dan Wolz, who had a passion for connecting with kids. “Dan saw the value in bringing sci-ence to area kids, especially envi-ronment and conservation issues, in an easily understood way,” recalls Myron Erickson, P.E., now Clean Water Plant superinten-dent. At the program’s peak, the outreach program reached some 1,200 students a year.
“Unfortunately, like many other municipalities, we’ve had to consolidate operations and staff and figure out how to do more with less,” Erickson says. “We cut back on plant tours to about 10 or 12 a year. But that’s still a couple hundred visitors every year, from third graders to graduate students. There are no better examples of applied science than can be seen at our Drinking Water and Clean Water plant tours.”
Visitors observe how water moves through each plant. Hand-outs include literature available from the AWWA, the Water Envi-ronment Federation and the U.S. EPA. Engineering students from area colleges and universities come to learn about plant design and mechanics; biology and chemistry students see the biochemical side of water treatment; and nursing students learn about the impor-tance of protecting public health.
Economic benefitsRegardless of visitors’ age or
education, the department deliv-ers the same basic message. “While environmental resources afford us many benefits, from health to recreation, we still need economic activity for communi-ties to thrive,” Erickson explains. “But if you conduct economic activity at the expense of the envi-ronment, sooner or later everyone suffers. Drinking water and waste-water treatment plants facilitate economic activity with the goal of protecting the environment and ensuring that clean water is avail-able for all needs for generations to come.”

Everyone leaves the plants with new awareness of how impor-tant water treatment is to society. “At the start of every tour, we try to surprise attendees by pointing out items — food, chairs, clothing — that require water to produce,” says Erickson. “Then we explain how that water was sourced and what it takes to get it back into the environment.”
Another aspect of the utility’s outreach is internships. “We bring in engineering and nonengineer-ing college students to teach them about an important function and interest them in a water manage-ment career,” Erickson says. He works with schools that offer water treatment associate degrees requir-ing internships. In 2012, Wyo-ming’s two interns were newly graduated mechanical and civil engineers.
“It was the perfect pairing of their experience with our own,” Erickson says. “We’ve already imple-mented some of their recommen-dations from an energy audit they conducted and will eventually move
forward with some of their long-term ideas, too.”
Final goal
Erickson points out that water utilities tend to operate under the radar of public awareness. Drink-ing water facilities may not be near the city center; wastewater treatment plants are often on city outskirts near the receiving stream. Water utilities aren’t at the top of employment opportu-nity lists, either.
“Unfortunately, actively pro-moting water careers isn’t a focus for us any longer, but the critical need to educate all ages about the importance of water to society and the environment, and the need for water conservation, will never change,” says Erickson. “My goal is for everyone who comes for a tour to be able to explain to any-one else, in everyday language, the purpose of these plants and how they function, and also their importance to our economy. And most people leave able to do that.” wso

mal life span of these lines but will actually extend their life.” The company is looking at cured-in-place pipe (CIPP) lining as one
way to accomplish that. “We’re experimenting now, looking at costs. If they’re reasonable, we’re looking to do that next,” Risoldi says.
Larger-diameter mains — 30 inches and above — are also get-ting attention: “We’re developing a larger asset condition assess-ment, determining the condition of our larger mains and determin-ing which technology we’re going to use. These are older mains and concrete pipes. They’re known to fail. We want to be proactive in their repair.” wso

Potable water disinfection requires specialized chemical feeders and chlorinators and accurate measurement of chemical dosing. UV disinfec-tion is a growing technology. Here are some of the industry’s latest disin-fection offerings.
Chemicals
Sodium HypochloriteSodium hypochlorite from American Devel-
opment Corporation is an oxidizer effective against bacteria and viruses. Residuals are read the same as for other disinfectants and must be removed in waste streams before discharge. Safety factors include fewer personal protective equipment requirements and no self-contained breathing apparatus. 888/542-8561; www.adc-chem.com.
Sodium Chlorite
ADOX sodium chlorite from DuPont Clean Water Technologies is used primarily in the generation of chlorine dioxide using DuPont MG III generators. Chlorine dioxide is being used in a growing number of industries due to its highly selective oxidizing properties, which result in a lower dosage requirement. It remains a truly dissolved gas in water and retains its useful oxidative and biocidal properties throughout a broad pH range (2 to 10 pH). Additionally, it does not chlorinate organics to form halogenated disinfection byproducts such as THMs and HAAs. It is utilized to disinfect potable water around the world and is approved for use by the EPA and the World Health Organization. 302/999-2709; www.dupont.com.
Chlorination/Dechlorination Equipment
Tablet dechlorinatorThe Zde-Chlorinator unit from Integra
Chemical Co. is a tablet dechlorinator for hydrant flushing and other tasks. It is com-pact and lightweight, made of 6061-T6 high-strength aluminum.

Amperometric chlorine residual analyzer solves iron-clogging issueProblem
A military base in North Carolina installed chlorination systems at two well sites. High iron levels in the groundwater clogged the membrane of the residual analyzer’s measuring probe and kept the chemical feed pumps from dosing at the rate needed to achieve the free chlorine resid-ual required for drinking water disinfection.
SolutionAfter two months of cleaning, membrane replacement and recalibra-
tion, the contractor replaced the analyzers with an FX-1000P-CS ampero-metric chlorine residual analyzer with integral PID controller from Foxcroft Equipment & Service Co.
The bare electrode design with constant cleaning and distilled white
vinegar pH buffer eliminated the fouling issue. The scalable 4-20 mA output provided the continuous signal required to maintain automatic residual con-trol with the metering pumps.
RESULTThe analyzer helped the base
regain compliance while reduc-ing the downtime, expense and labor to clean and recalibrate the analyz-ers every one to two weeks. 800/874-0590; www.foxcroft.com.
Ozone system resolves hydrogen sulfide, disinfection and color issues in well waterProblem
The Four Way Special Utility District (SUD), Eastern Angelina County, Texas, operates multiple potable water plants, serving both urban and rural customers. Well No. 3 flows at 1.1 mgd and serves over 2,000 rural customers. The presence of hydrogen sulfide, color due to the presence of tannic acids, and sulfur-reducing bacteria were issues for the district.
SolutionThe SUD’s consultant, Goodwin-Lasiter Inc., proposed ozone
treatment as the solution and submitted a design/treatment proposal to the Texas Commission on Environmental Quality. It was recognized that ozone systems employing the efficient Mazzei Injector Company GDT contacting system in the consultants’ design would provide precise control of the ozone dosage to achieve treatment objectives while avoiding the formation of byproducts such as THMs and bro-
mate. The commission granted approval for an integrated ozone treat-ment system incorporat-ing onsite oxygen pro- duction, ozone genera-tion and a Mazzei GDT-3090 Ozone Transfer skid to replace the cur-rent aeration system.
RESULTThe ozone system is now in operation at Plant No. 3. Finished water
monitoring/testing is reported as better than projected, eliminating hydrogen sulfide, color and disinfection issues. 661/363-6500; www.mazzei.net.
Analyzer monitors organics in source waterProblem
Seasonal variation, heavy rainfall and accidental contamination often affect raw water quality at the Los Filtros Water Treatment Plant in Puerto Rico, requiring immediate attention. The facility produces drink-ing water for 256,000 residents, receiving water from the Guaynabo and Bayamon Rivers.
SolutionFacility manager Nancy Ma. Cáceres Acosta coordinated with Daniel
Smith of Montanas Electric and Orlando Laguer of Nator Corporation to integrate a coagulation optimization package. Preliminary source water testing indicated variable concentrations of organic matter, known to consume coagulant and lead to the formation of disinfection byproducts (DBPs). A Real Tech UV254 analyzer was installed to monitor organics for coagulant dosing with dual stream capabilities to evaluate
process efficiency. The analyzer was packaged with an HMI con-trol panel and a remote teleme-try system.
RESULTThe facility captured multi-
ple organic contamination events on the influent source water stream. Phase 1 testing of the package presented an average monthly reduction of 22,917 pounds of chemical coagulant for $9,831 in savings. A 23 percent reduction was seen in sludge formation. Facility personnel are confident that the potential for DBP formation is limited. 877/779-2888; www.realtech.ca.

clean. The Red is subject to wide variations in organic matter and hard-ness, related to weather and the nature of the watershed, Hall observes. Normal flows range from about 3,000 to 5,500 cubic feet per second.
The main feeder streams include the Otter Tail River, with generally high water quality; the Bois de Sioux River, with very poor water quality; and the Wild Rice River. “Every river system that feeds the Red is vari-able, depending on how much rain we’re getting at the time,” says Hall.
At the old treatment plant, which used lime and soda ash softening and dual-media filtration, the wide source water variations overwhelmed the process. At the time, the source water included about 60 percent river and 40 percent well water. Potassium permanganate and sometimes
activated carbon were fed at the river pumping station, but at times that wasn’t enough. When taste and odor problems arose, complaint calls came in bunches.
Reliable processThe MWH engineering firm (then known as Montgomery Watson)
designed the new treatment plant. The Moorhead team has steadily improved on the design with instrumentation and updates to the SCADA system, originally supplied by Instrument Control Systems (ICS).
One river pump station and two well pump stations deliver raw water directly into the plant. The waters mix in an influent chamber, and the flow then enters two 5.5 mgd softening basins (Infilco Degremont). Typi-cally, only one basin operates at a time, and when both operate, they work in parallel.
Water in the basins is fed with lime and soda ash, along with ferric sulfate as a coagulant and polymer for flocculation. Ammonia is also added in the softening stage for bromate control in the downstream ozo-nation process.
The WEDECO ozonation/recarbonation chamber (Xylem) has six cells fed with variable amounts of ozone and carbon dioxide, depending on raw water conditions. Residual ozone is sampled at various points in the chamber.
Before final filtration, fluoride is added, along with sodium hexameta-phosphate for heavy metal sequestration and corrosion control. The

plant’s four dual-media filter cells each hold two feet of anthracite coal atop 12 inches of sand. The filtered water goes to the clear well, where chlorine is fed to combine with ammonia and form chlora-mines for disinfectant residual. The water is then delivered to the res-ervoirs and water towers (7.9 mil-lion gallons total system storage).
Ozone does itHall notes that ozonation is
the key to odor and taste control. “We ozonate at very high pH [at times 11 or higher] so that we benefit from some advanced oxidation,” he says. “Ozone has been a really big improvement since it came online in 1995. It helps break down the organic material. Sometimes we feed CO2 with the ozone as the pH is dropping down close to that of the product water. That helps with taste and odor, too.”
But it wasn’t technology alone that conquered the variability of Red River water. The plant staff’s diligence had a lot to do with it. “Since we started this plant, we have probably doubled or tripled the amount of online instrumentation,” says Hall. “Our SCADA gives us a lot of infor-mation about water quality and what’s happening in the process, and we’re constantly trying to improve that.”
The system’s programmable logic controllers and other control hard-ware are from Allen-Bradley (Rockwell Automation), and the SCADA software is from IntelliSys Inc. Online instrumentation in the treatment plant and water system includes:
• Three total chlorineanalyzers fromWallace&Tiernan (SiemensWater Technologies Corp.)
• Monochloramine/ammonia analyzer, five pH monitors, and eightturbidimeters from Hach Company
• Two pH controllers (CO2 auto control), four ozone analyzers and two conductivity meters from Rosemount Analytical (Emerson Process Management)
• Organiconlineanalyzerfroms::canMeasuringSystemsBenchtop lab equipment includes a turbidimeter and spectrophotometer
from Hach Company, total organic carbon analyzer from OI Analytical, an IC chromatograph from Dionex, now sold as Thermo Scientific – Water Analysis, and an Orion pH meter from Thermo Scientific – Water Analysis.
The team tests raw water for hardness and alkalinity every four hours and tests the finished water every eight hours. The ozone analyzers test the water in the ozone contact chamber every 20 seconds. Ozone dosage is adjusted manually based on monitoring for ozone residual. “We have to adjust the ozone feed rate as water quality changes — on a good day, just a couple of times; on a bad day, once an hour or more,” says Haman.
Water from Moorhead, Minn., won the first two “Best in Glass”
taste competitions held by the state section of the American Water
Works Association at its annual conference in September in Duluth.
The event includes a vendor show where water samples from
communities that enter the competition are subjected to a taste test
and a popular vote among the attendees. The field is narrowed to
the top three vote-getters, which go to a second round of tasting by a
panel of three from Minnesota section members and a celebrity judge.
“In both 2009 and 2010, we won both the popular and the panel
vote,” says Troy Hall, Water Division manager for Moorhead Public Service.
“The official winner is the sample selected by the panel of judges.”
Another honor awaits: The plant is to be featured during 2012 on
an episode of the Discovery Channel’s “Dirty Jobs” program, showing
the process of cleaning the softening basins. Says Hall, “It has been
a fun year.”

The SCADA is programmed with the U.S. EPA ozone contact time (CT) requirements for disinfection. The ozone analyzers feed data directly into the SCADA, which calculates the actual CT value in real time. “In operations, we adjust the ozone, pH or whatever parameter is necessary to make sure the actual plant CT value is above the EPA requirements,” says Haman. “Once we meet the disinfection require-ment, 99 percent of the time the odor and taste issues are taken care of.”
As a teamThe staff’s success derives in part from the team atmosphere its lead-
ers try to create. “There’s a lot of overlap in the way we do things — a lot of cross-training,” notes Kris Knutson, water plant supervisor. “We don’t like to keep secrets between positions. We expect all our operators to be very familiar with the SCADA. As a supervisor, I try to involve the oper-ators so they can help me out with data analysis, maintenance tasks, or whatever happens to come up.”
Halbakken adds, “We communicate with each other. If one of us sees a problem, we alert the others. Everybody is always looking to keep the best product going out of the plant at all times. If that means someone has to be called at three in the morning to deal with a problem, everybody’s open to that. Everyone’s willing to help out.”
Notes Haman, “We try to work to each other’s strengths and shore up our weaknesses. For example, Nate is better at plumbing than I am, so I’ll give him plumbing jobs. In turn, he can give me data to analyze to find out when is the best time to order lime. We each have our little projects and our specialties.”
Hall cites SCADA work as an example of the team’s cooperation. “For the past decade, we have done all our SCADA work internally,” he says. “It’s not a perfect SCADA, but it has been built by people who really care about the end result. When we want to make a change in how a process works, we all work together.
“I’ve done some SCADA work in the office. Kris and Dan have done screen development for various purposes. It has evolved almost entirely in-house. We also select and install our own instrumentation.”
Problem solversTeamwork has helped the Moorhead staff resolve a variety of process
issues. Several years ago, pH variability was a constant challenge. Work-ing together, staff members made the correction by installing pH probes, making plumbing changes, and doing SCADA programming.
In another instance, rising non-carbonate hardness in the Red River was taking a toll on the soda ash feed pumps. A former operator located a peristaltic pump model (Watson-Marlow) that appeared better suited to the task. Operators, an instrument technician and electricians from the utility’s electrical side worked together to test and install the new pumps. “In a few months, we went from having to service the pumps every week to having almost no problems,” says Haman.
Another improvement involved installing a meter in the intake line to sample Red River water for conductivity as a way to predict total hard-ness in the river in real time. The team did the job, including data analy-sis and SCADA programming, entirely in-house, installing a used instrument purchased on the Internet for a few hundred dollars.
Future plans include installing instrumentation at the river pumping station, about three miles (two hours of in-pipe travel time) from the plant. “I’m excited about that,” says Haman. “We’ll be able to see changes in the water before it gets to the plant and so deal with them more effectively.”
Hall calls it a privilege to lead a staff with many and diverse talents. “The strengths of our people make it all work,” he says. “We try our best every day to use the strengths of the people we have.”
The results show up daily in the water glasses of Moorhead residents. wso

MOORHEAD PUBLIC SERVICE DELIVERS HIGH-QUALITY WATER FROM VARIABLE SOURCESPage 10

TasTesGreaT!Technology and teamwork help Moorhead Public Service deliver consistently high-quality water from a highly variable source in Minnesota’s Red River
STORY: Ted J. RulSehPHOTOGRAPHY: John BoRge
The Red River is best known for periodic floods that afflict North Dakota, most notably around Grand Forks. Much farther south, in Moorhead, Minn., the river is known for something else, though mainly to the staff at the water treatment plant.
“Up here, it’s not a big river,” says treatment plant operator Dan Haman. “Local events can have a large impact on it. A rain event can often wash interesting water into the river, especially if the weather has been dry for a while.”
Years ago, that led to complaints from customers about odor and bad taste in the water coming from the tap. That no longer happens. In 1995, Moorhead Public Service added ozonation to its treatment process, and it proved to be a reliable cure. In fact, for the past two years, Moorhead’s water has been voted the best tasting in the state in a competition held by the Minnesota section of the American Water Works Association.
Troy Hall, Water Division manager, credits the treatment technology, along with a talented operations team, with keeping the process on track. “When we look at the SCADA and see our water-quality trends, we want to see flatlines — everything just humming along,” says Hall. “Through teamwork, that’s what we’ve accomplished.”
Variable sourceWhat the Moorhead team calls the North Treatment Plant (10 mgd
capacity) was built in 1995. The old 6 mgd treatment plant is now rarely used: The staff operates it periodically just to make sure it remains func-tional and available for emergencies. When the plant operates, it treats well water only.
The new plant, with 10 full-time and two part-time staff members, was designed specifically to deal with variable source water in the Red River. The utility also draws well water from the Buffalo Aquifer, but the river provides about 85 percent of the source water on an annual basis.
“There’s a reason it’s called the Red River,” says Nate Halbakken, lead treatment plant operator. Which is to say it’s not what one would call

clean. The Red is subject to wide variations in organic matter and hard-ness, related to weather and the nature of the watershed, Hall observes. Normal flows range from about 3,000 to 5,500 cubic feet per second.
The main feeder streams include the Otter Tail River, with generally high water quality; the Bois de Sioux River, with very poor water quality; and the Wild Rice River. “Every river system that feeds the Red is vari-able, depending on how much rain we’re getting at the time,” says Hall.
At the old treatment plant, which used lime and soda ash softening and dual-media filtration, the wide source water variations overwhelmed the process. At the time, the source water included about 60 percent river and 40 percent well water. Potassium permanganate and sometimes
activated carbon were fed at the river pumping station, but at times that wasn’t enough. When taste and odor problems arose, complaint calls came in bunches.
Reliable processThe MWH engineering firm (then known as Montgomery Watson)
designed the new treatment plant. The Moorhead team has steadily improved on the design with instrumentation and updates to the SCADA system, originally supplied by Instrument Control Systems (ICS).
One river pump station and two well pump stations deliver raw water directly into the plant. The waters mix in an influent chamber, and the flow then enters two 5.5 mgd softening basins (Infilco Degremont). Typi-cally, only one basin operates at a time, and when both operate, they work in parallel.
Water in the basins is fed with lime and soda ash, along with ferric sulfate as a coagulant and polymer for flocculation. Ammonia is also added in the softening stage for bromate control in the downstream ozo-nation process.
The WEDECO ozonation/recarbonation chamber (Xylem) has six cells fed with variable amounts of ozone and carbon dioxide, depending on raw water conditions. Residual ozone is sampled at various points in the chamber.
Before final filtration, fluoride is added, along with sodium hexameta-phosphate for heavy metal sequestration and corrosion control. The

TASTESGREAT!Technology and teamwork help Moorhead Public Service deliver consistently high-quality water from a highly variable source in Minnesota’s Red River
STORY: TED J. RULSEHPHOTOGRAPHY: JOHN BORGE
The Red River is best known for periodic floods that afflict North Dakota, most notably around Grand Forks. Much farther south, in Moorhead, Minn., the river is known for something else, though mainly to the staff at the water treatment plant.
“Up here, it’s not a big river,” says treatment plant operator Dan Haman. “Local events can have a large impact on it. A rain event can often wash interesting water into the river, especially if the weather has been dry for a while.”
Years ago, that led to complaints from customers about odor and bad taste in the water coming from the tap. That no longer happens. In 1995, Moorhead Public Service added ozonation to its treatment process, and it proved to be a reliable cure. In fact, for the past two years, Moorhead’s water has been voted the best tasting in the state in a competition held by the Minnesota section of the American Water Works Association.
Troy Hall, Water Division manager, credits the treatment technology, along with a talented operations team, with keeping the process on track. “When we look at the SCADA and see our water-quality trends, we want to see flatlines — everything just humming along,” says Hall. “Through teamwork, that’s what we’ve accomplished.”
Variable sourceWhat the Moorhead team calls the North Treatment Plant (10 mgd
capacity) was built in 1995. The old 6 mgd treatment plant is now rarely used: The staff operates it periodically just to make sure it remains func-tional and available for emergencies. When the plant operates, it treats well water only.
The new plant, with 10 full-time and two part-time staff members, was designed specifically to deal with variable source water in the Red River. The utility also draws well water from the Buffalo Aquifer, but the river provides about 85 percent of the source water on an annual basis.
“There’s a reason it’s called the Red River,” says Nate Halbakken, lead treatment plant operator. Which is to say it’s not what one would call

Dual-vessel purification system designed for quick setup
The CP 20K-10 activated carbon dual-vessel skid system from TIGG Corp. is designed for short-term water purification projects and compliance monitoring.
Units can be run in series or parallel and are capable of purifying more than 2.16 mgd. Each system can purify water at a maximum flow of 1,500 gpm (in parallel mode) and holds up to 40,000 pounds of granular activated carbon (GAC). It has a maximum pressure of 125 psi and maximum operating temperature of 130 degrees F.
“Using a two-vessel system running in series allows water to flow through the carbon bed in the primary vessel and then through a carbon bed as a secondary vessel,” says William Bland, chief engi-neer for TIGG.
“Both activated carbon adsorption vessels in TIGG’s CP20K-10 Skid System have three sample ports. This permits an operator to check for contaminant breakthrough at different levels in the carbon bed and determine when the vessel’s media is almost spent,” Bland says of the carbon bed, which can last for months without replen-ishment, depending on the amount and type of contaminates that it processes.
The dual-vessel system enables spent carbon to be changed out without having to shut down the purification process. Spent carbon can be reactivated or taken to a landfill for disposal. With few mov-ing parts, the system requires little maintenance.
“The biggest issues are making sure the tank lining integrity stays intact and that the valves are in working order,” Bland says.
