Weathering the Storm

Comments

Content

South American coal mine for several years, during which time his site compiled a safety record — based on statistics of workplace injuries — far below global norms for the industry. “You must be proud,” I once said to him. He replied, “I am ashamed to say that two workers were killed during the time I was in charge.” In his view, the only acceptable injury rate was zero. He felt that around any workplace mishap, one could always find something that could have or should have been done to prevent it. He was reluctant to accept that “accidents happen.”

T

he expectation — clearly and repeatedly communicated — is that first of all, everyone will go home each day without an intervening visit to a hospital. And that expectation of course is undermined unless every team member is on board with it. Keeping watch

That attitude starts from the top in any safety culture. And somehow it gets conveyed in ways that are not boring. Simply pestering people about safety — insisting that they “be more careful” — isn’t enough. And yet there needs to be an obsessiveness about the mundane details of keeping the workplace safe. The expectation — clearly and repeatedly communicated — is that first of all, everyone will go home each day without an intervening visit to a hospital. And that expectation of course is undermined unless every team member is on board with it. In other words, yes, there are safety rules here, and yes, following them is a condition of working on this team. On that point there is no negotiation. In such a context, safety lessons become less mundane, less like nagging, less boring. And that’s part of how those long injury-free spells get started, and continue. wso

THEY DID IT
It took a team of employees to set the Aldrich Station treatment plant’s mark of 11 years without a lost-time accident. The plant staff includes: • Production Superintendent Greg Tokar • Plant supervisor Sam Taylor • Operators Bill Tarr, Rich Fulton Jr., Duane Kavka, Jonathan Baker, Ron Palmer, Bob Jobb and Vic Davis • Maintenance/relief operators George Reskovac, Todd Rankin, John Milvet and Sal Herman • Maintenance staff Mark Trout and Jeff Kelly People who are no longer at the plant, but contributed to the safety record are Julia Alkhuzaee, Josh Dunkle, Jack Fouser, Jan Hart, Dave Razumic and Lena Rush, who transferred to other duties; and Joe Kobelak, Tom Betz, John Ohnhaus and Geno Olkosky, who retired.

The staff of E.H. Aldrich Station includes, from left, Greg Tokar, plant supervisor; Sarah Restivo, water quality supervisor; Mark Trout, maintenance worker; Jonathan Baker, operator; Sal Herman, maintenance relief worker; Rich Fulton, operator; Jeff Kelly, maintenance worker; John Milvet and Todd Rankin, maintenance relief workers; and Sam Taylor, plant supervisor.

lunch, and it involves the corporate safety team and the company president if possible. Employees receive gift cards or commemorative items like high-quality flashlights.

Change in disinfection
The emphasis on safety has led to process improvements at Aldrich Station. One of the most significant involved the chlorine contact operation. “We’re surrounded by a small town of about 300 residents,” explains Taylor. “A lot of people live within half a mile of the plant. We were using 1-ton chlorine cylinders and had quite a few of them on site. It was a potential hazard to our workers but also to the community.” For safety reasons, the plant management decided to get away from gaseous chlorine, switching to sodium hypochlorite generated in a new 4,000-square-foot building that houses a system supplied by Severn Trent. Taylor says management made the change as part of a recent multimillion-dollar upgrade at Aldrich Station and the nearby Hays Mine Water Treatment Plant operated by American Water. “Between the two plants, we probably had the largest supply of chlorine tanks in the whole state,” he says. In addition, the Aldrich Station plant now feeds liquid ammonia to maintain chloramines in the distribution system rather than free chlorine. This chloramination approach ensures a residual all the way to the end of the line — the West Virginia border in some cases — while reducing the threat of disinfection byproducts. Finally, the old pneumatic actuators on valves throughout the plant are becoming extinct. “We are moving to Beck electric actuators,” says Taylor. “They’re safer in that they won’t move on their own during a power outage.”

Safety culture
Of course, safety programs and improvements won’t make a lasting difference unless they’re supported by a culture of safety that extends throughout the plant. That’s clearly the case at the Aldrich Station. “We

want safety on everyone’s mind,” says Hufton. “We want to be proactive, to make safety a value here.” Hufton says the in-house approach to maintenance helps, because everyone understands how everything works: “The safer we are, the happier we are. Morale is high here. Our people look out for themselves as well as others. You see something, say something. We’re proud of our record, proud of being able to accomplish major projects and have everyone walk away safe.” Taylor recalls one situation where the replacement of high-service pumps required the removal of large, heavy gate valves, as well.

WINNING THEM OVER

Making Conservation Pay
BY PETE LITTERSKI

Richard Chapman, co-owner of Smart Use, teaches customers to calculate how much water they need for their landscapes as part of a class offered by the Albuquerque Bernalillo County Water Utility Authority.

$20 credit instrumental in attracting up to 400 people at a time for the hour-long classes offered six times a year during the summer watering season. The classes are pretty basic. Consultant Richard Chapman of Smart Use teaches customers to calculate how much water they need for their landscapes and how to set the most effective watering schedule. He also tells about water-conserving plantings and other ways to reduce watering. Participants receive information about xeriscaping, free water-use audits, and the utility’s outdoor rebates. Yuhas says reducing water consumption is significant in a region where the average annual rainfall is about eight inches. The authority, which serves 623,000 people, gets about 40 percent of its water from surface sources and the rest from the Middle Rio Grande Aquifer. Albuquerque has continued growing despite the 2009 recession, but water demand has dropped. In 1994, the authority set out to reduce per The conservation program has been around almost 20 years, and we’re always capita usage from 252 to 150 gpd. trying to think of better ways to get people involved.

KATHERINE YUHAS The Water Smart classes are effective, but they are only the newest initiative in a comprehensive effort to conserve water. “The conservation program has been around almost 20 years, and we’re always trying to think of better ways to get people involved,” Yuhas says. “It’s really about protecting our aquifer. We’re in a situation where there isn’t any more water to get.” For adults, the utility offers a second Water Smart class (not covered by the rebate program) on how to design a drip irrigation system or convert an existing sprinkler system to drip irrigation. The authority offers a variety of other incentives for people to conserve water. The outdoor rebate program includes: • 25 percent of the cost of a multi-setting sprinkler controller • 25 percent of the cost (up to $50 credit) to rent sod removal equipment for xeriscaping • 25 percent of the cost (up to $100 credit) for compost for xeriscaping • $25 each for rain sensors, pressure regulation valves and pressure vacuum break (PVB) backflow prevention valves • Rainwater harvesting equipment rebates based upon storage volume Laura Ferrary, co-owner of Smart Use, teaches water conservation. Customers • $2 per head for multi-stream rotor heads for sprinklers receive a $20 credit on their bills for attending. utomakers offer cash rebates. Shoe stores offer buy-one-getone-free deals. Grocery stores offer double-coupon days. And the Albuquerque Bernalillo County Water Utility Authority offers a $20 credit on customers’ bills if they attend a free “Water Smart — How to Water Your Landscape” class. Authority conservation manager Katherine Yuhas says the program has been effective in spreading the message about the importance of water conservation in New Mexico’s high desert metropolis. The Water Smart program completed its fourth year in 2012 and, despite two years of extreme drought, “We’ve recorded our two best conservation years,” Yuhas says. The authority tracks water usage and finds that customers who take the class reduce their outdoor water use by 18 percent compared to other customers. For the average home, that’s a savings of 9,000 gallons per year. More than 10,000 water customers have taken the class in the past four years. Yuhas says face-to-face contact is the most effective way to bring the water conservation message to consumers, and she considers the

with industrial users’ demand for water. In 1960, production increased to 8 mgd with an addition of a circular package plant. A 1995 upgrade brought that up to 12 mgd. Treatment then consisted of potassium permanganate and ferric chloride feeds followed by flash mixing with lime addition. From there, the water was fed to the floc chamber, then to the settling basin and sand filters. Fluoride and chlorine were added before the water was sent to the clearwell. The 2008 rebuild/conversion to membrane technology increased capacity to 13.2 mgd. “With each upgrade, we’ve tried to maintain the historic nature of the building and the site,” says Rush. “With the 2008 upgrade, we combined the old with the new.” Don Johnson, water and wastewater treatment manager, adds, “We started looking at system designs and pilot testing three years before the new plant was built. We asked the operators for input, since we wanted to know how they felt about the technology and the different systems.” Rush comments, “We pilot tested two different submerged membrane systems and ultimately chose this technology because it could be retrofitted into a smaller space and consume less energy. We then got together with the operators and our engineering firm to talk about where the pumps and valves should go for ease of operation.”

Rehab goals
There were many goals in rehabilitating Mill Creek, including the ability to meet regulatory and quality expectations for the next 20 years. “The driver for choosing membranes was regulatory, including the Long-Term 2 (LT2) surface water treatment rule for Cryptosporidium and Giardia removal, and the Stage 2 disinfection byproducts rule,” Rush says. Other objectives were to reduce the footprint and flood-proof the plant. “We increased capacity while reducing the filter footprint from 2,000

AWARD-WINNING TEAM
The operations team at Dalton Utilities Mill Creek Water Treatment Plant has garnered 21 awards since 1999. These include: • 14 consecutive years of Georgia Association of Water Professionals (GAWP) Gold or Platinum awards for excellence in plant operations • GAWP Top Operator (Top Ops) awards: Rob Campbell in 2009

and Dale Stanley in 2011 • 2006, 2010 and 2012 GAWP Water Treatment Plant of the Year awards • Two GAWP 2011 taste test awards (district and state) How do they do it? Experience helps, but so do determination and training. While none had experience with membrane technology, the operators’ average length of time in the water business is 18 years. The utility offers ongoing certification and recertification training with water treatment, water management and safety classes.

The operators report to Ed Stanley, water plant supervisor, who holds Class I certification and has been with Dalton Utilities for 24 years. He covers all the utility’s water plants. His staff includes: • Bruce Blackwell, water plant shift supervisor, Class I, 19 years • Dale Stanley, operator, Class I, 27 years • Keith Collins, operator, 21 years • Dan Findlay, operator, 20 years • Tommy Ellis, operator, 17 years • Jamie Cox, operator, 16 years • Rob Campbell, operator, 14 years



square feet to 576 square feet,” says Rush. “We were able to do this by using existing buildings and because the membranes take up less space than the sand filters.” Flood-proofing involved raising power transformers and all doors and windows above the floodplain and installing a submarine door to protect electrical equipment. Other modifications included: • A new roof on the filter building so the membrane tanks could be installed inside. • A switch from fixed to variable-speed pumps. • Piping modifications and a new mixer for the flash mix structure • Sedimentation basin well screens that use gravity, thereby reducing energy costs. Completed on time and under budget, the upgraded plant is functioning as designed and meeting regulatory requirements. Operating costs have been reduced, as the membrane system requires fewer chemicals. It also creates less sludge. The new system flow path is similar to the old one: raw water is treated with sodium permanganate and poly-aluminum chloride before it is sent to the Chemineer flash mixer, floc chamber and settling basin. From there it flows to 1 mm Johnson Screens gravity well screens and on to the membrane system (Siemens Water Technologies).

“Our new plant had a short startup period because we didn’t want to go through the whole summer with the other plant treating our water,” Johnson recalls. During startup, Mill Creek operators performed a dry run with the membrane system, testing and wasting the water. “That is where a lot of their training came in,” says Rush. “The contractor was there during that time, which helped.” Despite the training, it took oper-

side, the fact that our plant has expanded its capacity may attract more businesses, and we have had several new industries come to town.”

Learning about membranes

The plant’s six operators knew nothing about membrane treatment before the plant upgrade and went through two months of classroom and hands-on training from Siemens. “Basically, it was like starting all over,” says Johnson. “All LESLIE RUSH they knew was sand filtration.” It helped that the operators were on site during construction and understood the changes being made as the renovation progressed. During construction, the V.D. Parrott Jr. plant operated at a higher flow to treat the Mill Creek plant’s water. “Our distribution system is interconnected, so we used the other plant’s services for a full year until Mill Creek was ready,” says Rush. The Mill Creek plant kept its old package plant online during that time to treat some of the water, while V.D. Parrott Jr. treated 4 to 5 mgd of the influent.
