AWWA M36 Water Loss Audit Information
Each year millions of gallons of water are lost to leakage, meter error, and water theft. The American Water Works Association (AWWA) has created the M36 Water Loss best practices program to help utilities measure and mitigate these losses. The program includes an audit guide, utility water audit summary statistics and regulatory developments.
The AWWA Water Audit method was developed jointly by the International Water Association and AWWA. The AWWA believes that this method provides the best management practice tools and guidance water utilities need to efficiently manage their supplies.
AWWA/IWA Water Loss Audit Software is available for FREE from AWWA. Visit their Water Loss Control page and fill out their short form to receive the latest version.
The Colorado Water Loss Initiative (CWLI) from 2019-2020 provided a comprehensive program of M36 Water Loss training and technical assistance to participating utilities. It was the combined effort of Colorado's Department of Natural Resources, the Colorado Water Conservation Board (CWCB), Cavanaugh and WSO.
