On March 15, 1996, the Edwards Aquifer Authority (EAA), formerly the Edwards Underground Water District, received a request from the City of Marion to perform a leak detection I location survey on its water distribution system. A pre-survey conference was held April 4, 1996 at the City of Marion to discuss the work to be performed. It was agreed that EAA wou ld 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 of Marion by EAA at the conclusion of the survey.
