Description

A Pro-Active Leak Detection Program for Madison Suburban Utility District The Madison Suburban Utility District is located just north of Nashville, Tennessee and serves 70,000 customers via 285 miles of potable water pipelines. It was formed in 1939 serving 1200 customers. The district has a water treatment plant with a maximum capacity of 16.5 MGD and a peak system demand of 10.5 MGD. The district has embarked on a 3-year pro-active leak detection program using satellite-based surveys to identify likely leak locations in the system. This information is used to direct leak detection crews to specific areas where there is a higher density of leaks. The first of six services has identified 26 leaks in the system that account for 100,000 gallons per day of real water loss. 92 % of the leaks were non-surfacing and would not have been located if not for the pro-active program. This presentation will discuss how the district operationalizes the satellite survey data to direct staff to look for leaks; how and where crews are deployed and scheduling repairs. The presentation will also review value proposition and real water loss reductions over the course of the program.
