A major military base in the Northeast United States experienced an increasing number of watermain leaks in its 60-year old distribution system, and its Public Works crews lacked an effectivemethod for detecting and locating the leaks. Some of the water leaks surfaced and were easilyfound while others went undetected for extended periods, discharging to underground sinkholes.The Public Works crews had used labor-intensive methods to find leaks or contracted with a leak detectionservice. They were looking for a tool that would help them rapidly respond to leaks andultimately reduce costs.Engineers evaluated six leak-detection options. The study examined the advantages,disadvantages, costs, and technical limits of each method. Two technologies, leak detection fieldsurveys and permanently mounted noise detectors, were found to be the most accurate andsensitive options. Includes 2 references, figures.
