FCS Permalog Leak Detectors Reduce Birmingham’s Non-Revenue Water
Non-revenue water down by 55% over two years with leak noise loggers
Milford, OH (November 5, 2009) – Using Permalog leak noise loggers from Fluid Conservation Systems, the Birmingham Water Works Board (BWWB) reduced non-revenue water (NRW) for the city of Birmingham, Alabama by 55% over the last two years.
According to BWWB officials, NRW is a combination of real and apparent water loss. Real water loss is the physical loss of water resulting from leaks in the system. With the help of Permalogs, BWWB reduced real water loss to 5.36 percent. Apparent water loss includes meter inaccuracies, unauthorized consumption and authorized unmetered consumption such as fire fighting, fire service line testing, water quality flushing and street cleaning.
“The utility now has 4,200 Permalog units installed,” says BWWB Revenue Water Department Manager Geoff Goodwin. “Between 2004 and 2008, the devices located more than 700 leaks.”
In addition to using Permalogs, the BWWB employed district metering, pressure management, increased meter accuracy, and new American Water Works Association and International Water Association methodologies to reduce NRW.
The BWWB (www.birminghamwaterworks.com) was founded in 1951 and serves 600,000 people in Jefferson, Shelby, Blount, St. Clair and Walker counties.
