New Braunfels Utilities Cuts Water Loss by 50 Percent with FCS Leak Detection

Equipment helped department exceed water loss reduction goal

Milford, OH (December 14, 2011) – Texas-based New Braunfels Utilities (NBU) used leak detection equipment from Fluid Conservation Systems (FCS) to build an efficient maintenance program for its distribution network while drastically reducing water loss. The equipment allows NBU to conduct scheduled repairs on its pipelines instead of dealing with leaks on an emergency basis.

NBU workers use an FCS TriCorr Touch correlator to locate leaks and conduct scheduled maintenance.

The NBU leak detection and valve maintenance program was established in 2009 to reduce water loss and increase system and valve reliability for NBU’s 456 miles of pipeline and 24,000 customer connections. At the end of the first year of the program, NBU calculated its average water loss at 2,000 gallons/ mile/ day.

Recognizing the need for improvement, NBU purchased FCS leak detection equipment including Xmic ground microphones, a SoundSens “i” correlating noise logger, a TriCorr Touch correlator and Permalog acoustic leak noise data loggers. The team began using the equipment to perform preventive maintenance on 750 valves per year and proactively scan the city for non-surfacing leaks. Two years later, NBU estimates its average water loss at 961 gallons/ mile/ day, less than half the loss rate during the program’s first year.

“Everyone knows that water is a precious resource and its preservation requires a ton of attention,” said NBU Operations and Maintenance Division Manager, Trino Pedraza. “We tested many products in the field and found FCS to have the highest level of reliability.”

FCS Permalog data loggers attach magnetically to pipelines and use advanced algorithms to discern the acoustic signature of leaks from background noise. SoundSens “i” and TriCorr correlators analyze data from acoustic sensors to approximate a leak’s location. The FCS Xmic electronic ground microphone amplifies noise generated by water escaping from buried supply lines under pressure, allowing users to pinpoint a leak’s location.

FCS Helps Town of Mooresville, N.C. Improve Response to Water Leaks

Equipment finds leaks before digging to minimize repair costs and road closures

Milford, OH (June 27, 2011) – Water leak detection specialist Fluid Conservation Systems (FCS) helped the town of Mooresville N.C. save money and resources while keeping in compliance with state regulations.  With FCS leak detection equipment, Mooresville can now identify and repair leaks in its water distribution network as they occur.

The Mooresville Public Services Department installed FCS equipment allowing leaks to be found and repaired as they happen.

The Mooresville Public Services Department installed FCS equipment allowing leaks to be found and repaired as they happen.

Mooresville is a town of 33,000 people that provides an average daily flow of 3.24 million gallons of water to 13,000 homes and businesses.  In the summer of 2008, officials at Mooresville Public Services Department were experiencing a 10% non-metered water rate in their 240 miles of water mains.  Underground water leaks were causing damage to roadways, and the extensive digging required to find and repair these leaks was expensive and caused heavy traffic congestion.  With the passage of North Carolina House Bill 2499 requiring public water services to develop and implement water conservation measures, as well as new industry moving into town that would drastically increase water usage, officials knew it was time to upgrade their water distribution network maintenance program.

After evaluating competing products, Mooresville officials decided that acoustic leak detection equipment from FCS most closely met with their operational and budget requirements.  “The FCS equipment was compatible with our record keeping system and simple enough so that the guys in the field could use it and feel confident that they were collecting accurate results,” said Mooresville Public Services Director, John Vest.

Vest contacted local distributor Carolina Meter & Supply (Hampstead, N.C.) and purchased Permalog leak noise loggers, L-Mic and X-Mic ground microphones, an AC Digital leak noise correlator, and a Patroller II system to allow leak data to be collected from a moving patrol vehicle.  The equipment was fully installed and in use by the fall of 2009.

In April of 2010, Mooresville Public Services staff had located and repaired 24 leaks, saving an estimated total of $80,000 annually.  Workers were pinpointing leaks accurately, allowing preventative maintenance work to be scheduled with advance public notification to avoid traffic congestion.  “The FCS equipment has really enhanced our planning capabilities.  We’re finding leaks before they become a problem,” said Field Operations Supervisor, WD Bumgarner.

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.

BWWB officials used the FCS Permalog to reduce non-revenue water.

BWWB officials used the FCS Permalog to reduce non-revenue water.

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 ( was founded in 1951 and serves 600,000 people in Jefferson, Shelby, Blount, St. Clair and Walker counties.
