This new technology pinpoints leaks in large diameter mains without the set-up intensive, and intrusive, techniques used by other technologies. ADS is the only authorized service provider of this technology which utilizes the Echologics LD Leakfinder for large diameter leaks.
ADS was asked to locate a potential leak on a 36' concrete main on September 11, 2007. The leak was showing in a basement of a nearby building. Echologics Hydrophone sensors were placed on the hydrants off the 36' main at a distance of 829 feet. After implementing the signal processing algorithms, the leak came up instantly, and was located to within inches. The leak was found to be located at a concrete to iron adaptor with a torn gasket.
ADS has proven they can find leaks in large pipes without inserting equipment into the pipe. The accuracy of this technology in pinpointing the leak is also superior to other technologies. ADS provides leak detection services to the City of Chicago as part of a Hydraulic Engineering Services contract that also includes, loss of head tests, flow and pressure measurements, flow profiling, hydraulic gradients, fire flow tests and valve exercising.
