On May 12, 1995, the Edwards Underground Water District (EUWD) received a request from the City of Converse to perform a leak detection I location survey on its water distribution system. A pre-survey conference was held June 28, 1995, at the City of Converse Public Works Center 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 the City at the conclusion of the survey.
John E. Gapinski of EUWD began the survey on July 5, 1995, and the survey was concluded on October 24, 1995. Over the course of the survey, EUWD surveyed a total of 4,758 access points including 3,455 customer service connections, 306 fire hydrants, 922 valves, and 75 other access points covering 46.27 miles of distribution main. Computer leak sound correlation was performed at 1 location by EUWD.
EUWD surveyors detected 47 utility side leaks and 39 customer side leaks for a total of 86 leaks. The utility side leaks included 9 service leaks, 30 meter box leaks, 2 main valve leaks, 1 main leak, and 5 fire hydrant leaks. EUWD estimates 29,581 gallons of water per day has been saved by the repair of 39 utility side leaks as of October 24, 1995. The leaks discovered during the survey range from 13,680 gallons per day to numerous small meter box leaks.
As part of the survey, EUWD located 118 valves of various types, 66 fire hydrants, and 11 ,400 feet of main not shown on the master water plats. EUWD surveyors were unable to locate 54 valves of various types and 1 fire hydrant shown on the master water plats. An additional 37 items were discovered to need some type of repair or adjustment.
