American Water Announces Pilot Program in Water Loss Management

Connellsville, PA Pilot Uses AMR Technology to Detect and Repair Leaks

Voorhees, NJ - June 24, 2005

American Water, the largest water services provider in North America, today announced a first-of-its-kind program that uses acoustic information from an automatic meter reading (AMR) system to detect and repair water leaks. Leaks are a problem plaguing public water systems nationwide. In its 2005 Report Card for America's Infrastructure, the American Society of Civil Engineers states that "each day, six billion gallons of clean, treated drinking water disappears, mostly due to old, leaky pipes and mains...enough water to serve the population of a state the size of California."

The unique AMR program, piloted in the Connellsville, PA water system, has equipped 500 of the water meters with an "MLOG" leak detecting sensor, manufactured by Flow Metrix, and an AMR transmitter as part of a fixed network system designed by Hexagram, Inc. Permanently installed on pipes near water service meters, MLOG sensors record sound vibrations over a period of four hours each night. Specially designed software analyzes these acoustical patterns and assigns them one of four leak categories: no leak present, possible leak, probable leak, or no data available.

"Leak monitoring with AMR allows us to locate and repair leaks that would normally remain undiscovered until they caused significant damage," said Wayne Morgan, VP Business Performance for American Water's Northeast Region. "This technology offers us the opportunity to examine an aging distribution system and explore the nature of water main leaks- from the time they start, to the time they become visible and severe enough to be repaired."

American Water chose Connellsville as the site of its leak monitoring trial because of the city's unique geography: it sits on a hillside along the Youghiogheny River, enabling leaks to flow underground to the river undetected. Additionally, Non-Revenue Water (NRW) exceeds 25 percent, and the cost of water is purchased at a premium for the system, providing a strong financial driver for effective leakage reduction.

By utilizing the MLOG leak detection system, American Water will reduce operating expenses, decrease water wastage and increase water availability in Connellsville. "This program promotes water resource conservation and gives American Water an affordable, round-the-clock means of detecting and repairing water leaks in Connellsville," said Morgan.

The Connellsville pilot is one of a series of water leak programs American Water plans to monitor within the next year, including two already-completed projects in Uniontown, Pa. and Manville, N.J., which utilize MLOG sensors, but not AMR technology.

American Water offers a comprehensive menu of water loss management services, including water loss system evaluation, leak detection, meter management, a LineSaver Service Line Protection Program for homeowners and network repair and replacement.
