The water audit process starts by gathering your data. That process is described in the webinar on March 1, 2017. Once the data is collected, you are ready to enter it into the free Water Audit Spreadsheet from AWWA. This webinar discusses the water audit process and how and where to enter the data as well as determining the appropriate data grades for your information.
