On May 5, 1992, the Edwards Underground Water District (EUWD) received a request from the City of Live Oak to perform a leak detection I location survey on its water distribution system. A pre-survey conference was held Decen’!-ber 14, 1994 at the City of Live Oak 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 February 6, 1995, and the survey .was concluded on April 7, 1995. Over the course of the survey, EUWD surveyed a total of 3,062 access points including 2,253 customer service connections, 177 fire hydrants, 551 valves, and 81 other access points covering 27.92 miles of distribution main.
Computer leak sound correlation was performed on 19 locations by EUWD. EUWD surveyors detected 35 utility side leaks and 97 customer side leaks for a total of 132 leaks. The utility side leaks included 27 service leaks, 5 meter box leaks, and 3 fire hydrant leaks. EUWD estimates 27,634 gallons of water per. day has been saved by the repair of 35 utility side leaks as of June 8, 1995. The leaks discovered during the survey range from 5, 100 gallons per day to numerous small meter box leaks.
As part of the survey, EUWD located 67 valves of various types, 15 fire hydrants, and 500 feet of main not shown on the master water plats. EUWD surveyors were unable to locate 25 valves of various types shown on the master water plats. An additional 11 items were discovered to need some type of repair or adjustment.
