On December 21, 1995, the Edwards Aquifer Authority (EAA) received a request from the City of Garden Ridge to perform a leak detection I location survey on its water distribution system. A pre-survey conference was held February 21, 1996, at the City of Garden Ridge City Hall to discuss the work to be performed. It was agreed that EAA 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 EAA began the survey on March 1, 1996. The survey was concluded on April 30, 1996. Over the course of the survey, EAA surveyed a total of 914 access points including 696 customer service connections, 71 fire hydrants, 136 valves, and 11 other access points covering 19.09 miles of distribution main.
Mr. Gapinski detected 15 utility side leaks and 11 customer side leaks for a total of 26 leaks. The utility side leaks included 10 service leaks, 2 meter box leaks, 2 main leaks, and 1 fire hydrant leak. EAA estimates 69,016 gallons of water per day has been saved by the repair of 15 utility side leaks as of May 21, 1996. The leaks discovered during the survey range from 28,368 gallons per day to small meter box leaks.
As part of the survey, EAA located 47 valves of various types, 200 services, 11 fire hydrants, and 11, 150 feet of main not shown on the master water plats. EAA surveyors were unable to locate 20 valves of various types shown on the master water plats. An additional 2 items were discovered to need some type of repair or adjustment.
