Water works expands leak detection reach

Fluid Conservation Systems will provide 1,210 Permalog + leak noise sensors to the Birmingham Water Works Board in order to lower costs and conserve water for the city of Birmingham, AL. This recent order is an addition to the 1,950 Permalog sensors currently in operation. The city began using FCS equipment in 2005 with an initial purchase of Permalog 3 leak noise sensors.

• City of Birmingham, AL, to utilize 1,210 Permalog leak detectors to reduce water loss and costs

MILFORD, OH, April 11, 2008 -- Fluid Conservation Systems (FCS) has contracted to provide 1,210 Permalog™ + leak noise sensors to the Birmingham Water Works Board in order to lower costs and conserve water for the city of Birmingham, AL. This recent order is an addition to the 1,950 Permalog sensors currently in operation.

The Birmingham Water Works Board began using FCS equipment in 2005 with an initial purchase of Permalog 3 leak noise sensors. Deployed throughout a utility's distribution system, Permalogs attach magnetically to valves and use advanced algorithms to discern the acoustic signature of leaks from background noise. The units 'wake up' and listen during the night when ambient noise is at its lowest. If leak noise is detected, the unit reports this information via a two-way radio link, along with the general location of the leak to a mobile unit that can then send a crew to pinpoint and repair the leak.

After three years of successful operation, the city decided to expand the reach of their monitoring system with the purchase of the new and improved Permalog +. An upgrade from the Permalog 3 unit, the Permalog + features increased battery life and memory capacity, improved leak noise recognition and data transmission speeds, and a smaller and more flexible design that allows for multiple data collection methods.

Birmingham is one of the largest water utilities in the country with nearly 4,000 miles of water transmission lines. The Permalogs will allow the Water Works Board to regularly check the entire service area for leaks, which was previously impossible with the amount of staff and time available.

Fluid Conservation Systems (FCS), a division of Halma Water Management, is the North American industry leader in water leak detection technology.
