The Water Loss Technical Assistance Program (Water Loss TAP) aids urban water suppliers in complying with California Senate Bill 555, requiring utilities to submit a completed and Level 1 validated water loss audit annually to the California Department of Water Resources (DWR).

The Water Loss TAP is brought to you by the California-Nevada Section AWWA.  This project has been funded by the Environmental Protection Agency and the State Water Resources Control Board.  The contents of this website do not necessarily reflect the views and policies of the EPA or the SWRCB, nor does the EPA or the SWRCB endorse trade names or recommend the use of commercial products if mentioned in this website.
