New equipment helps eliminate exploratory digging to find leaks
Milford, Ohio (February 20, 2013) – Fluid Conservation Systems (FCS) leak detection equipment has helped Greenville Water (Greenville, S.C.) maintain its tight distribution network and low water rates for customers in a more efficient manner.
Greenville Water is responsible for maintaining 2,800 miles of mains to serve 168,000 metered connections in the city of Greenville and surrounding areas with a daily average of 58 million gallons of water. Some sections of the primarily ductile and cast iron distribution network are over 100 years old.
“We’ve always prided ourselves in keeping a tight water network,” says Greenville Water Chief Operations Officer Murray Dodd. “But our leak detection methods were not efficient, and when a leak was discovered it sometimes took a work crew a full day to find and repair the leak.”
Work crews would sometimes have to dig several holes in an attempt to find the exact location of the leak, and Dodd was becoming concerned with the cost associated with excavating and backfilling these “ghost holes.”
After a product demonstration from Carolina Meter and Supply (Hampstead, N.C.), Greenville Water purchased FCS leak detection equipment, including 30 Permalog leak noise loggers, a Patroller II drive-by data collection system, a DigiCALL+ correlator and an X-Mic ground microphone. In 2012, the full-time, two person leak detection team found 57 previously undetected leaks using Permalogs, and assisted in pinpointing over 100 additional running leaks. Dodd estimates that the leaks found and repaired saved 20 million gallons of water in 2012 alone.
