Free Water Audit Software, Version 4.2 (2010), from AWWA

The American Water Works Association (AWWA) is offering an updated version of its water audit software – at no cost.

This excel spreadsheet-based water audit tool is designed to help quantify and track water losses associated with water distribution systems and identify areas for improved efficiency and cost recovery.  It provides a “top down” summary water audit format, and is not meant to take the place of a full-scale, comprehensive water audit format.  Version 4.2 includes an important new data-grading capability that allows the auditor to rate the overall degree of validity of their water audit data.  Guidance on loss control planning is given based upon the credibility of the data and the measure of losses displayed by the water audit.  For more information on the software and to download a copy of the tool, please go to:
