On February I 7, 1995, the Edwards Underground Water District (EUWD) received a request from the East Medina County Water Supply Corporation (EMCWSC) to perform a leak detection/ location survey on its water distribution system. A pre-survey conference was held at the EMCWSC office to discuss the work to be performed. It was agreed that EUWD would perform sonic leak detection on all available access points and computerized leak location as needed. A final report, including any unusual system condition found and an updated master water plat would be submitted to East Medina County Water Supply Corporation, by EUWD at the conclusion of the survey.
Mark L McGinnis of EUWD began the survey on August 10, 1995 , and the survey was terminated on October I 0, 1995. Over the course of the survey, a total of 287 access points were surveyed including 219 customer service connections, 240 valves, and 34 other access points covering 12.74 miles of distribution main.
Ten utility side leaks and 28 customer side leaks were detected for a total of 38 leaks. The utility side leaks included 2 meter box leaks, 7 main leaks, and I service leak. An estimated 1,730 gallons of water per day has been saved by the repair of the 10 utility side leaks. The leaks discovered during the survey range from 720 gallons per day to small meter box leaks.
As part of the survey, 6 services and 17 valves of various types were located that were not shown on the master water plats. EUWD surveyors were unable to survey 13 valves and 3 services shown on the master water plats.
