On November 20, 1995, the Edwards Aquifer Authority (EAA) received a request fromthe Fairco Water Company to perform a leak detection I location survey on its waterdistribution system. A pre-survey conference was held November 15, 1995, at the FaircoWater Company Office 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 Company at the conclusion of the survey.
