The California Water Loss Control Technical Assistance Program (Water Loss TAP) was funded wholly or in part by the United States Environmental Protection Agency and the State Water Resources Control Board, through the State Revolving Fund set-aside for technical assistance.  We are grateful to the EPA and Water Board for their support.  The Water Loss TAP was implemented by the California-Nevada Section AWWA, with support from the WSO/Cavanaugh Program Management Team.
