MILFORD, Ohio — Leak detection equipment from Fluid Conservation Systems (FCS) has helped the town of Roaring Springs, Pa. cut its non-metered water usage by almost half.
Roaring Springs Water and Sewer Authority maintains 26 miles of main lines with 1,200 metered connections to serve its population of about 3,300. In January 2011, daily water loss averaged almost 460,000 gallons, about 50 percent of the water pumped. Chairman Terry Glunt recognized the need to increase efficiency and instructed his department to investigate options for leak detection equipment.
After comparing similar products, Roaring Springs purchased six Permalog leak noise loggers and a Patroller II data collector from local FCS distributor L/B Water Service, Inc. During a product demonstration, the loggers immediately found three leaks accountable for an estimated loss of 13,000 gallons per day. Today, with continued product training and the purchase of a Tri-Corr Touch correlator, Roaring Springs has found 17 leaks and cut water loss to 27 percent.
Permalog noise loggers attach magnetically to pipes and “listen” for noise caused by leaks. Data from the Permalogs is then collected wirelessly by the Patroller II and analyzed using the TriCorr Touch correlator. This allows leaks to be quickly identified and pinpointed, minimizing exploratory digging, damage from erosion and lost resources.
In April of 2012, a shockwave generated from an explosion at a nearby rock quarry produced a leak in an 8-inch ductile iron main almost a half mile away. Roaring Springs Maintenance Supervisor Dane Noel noticed that water usage was up 40,000 gallons the next morning and 110,000 gallons the following day. Using the leak detection equipment, Roaring Springs employees were able to quickly find and stop the leak. “If we wouldn’t have had loss rates down so low, we never would have known what happened,” said Noel.
In 2012, Roaring Springs estimates the reduced non-metered water usage will save the town over $15,000.
