About the CWLI:

The AWWA M36 water audit methodology is recommended best practice in North American to support informed decision making for water loss control and revenue recovery.  Cost-effective water loss management reduces cost, increases revenue, serving the utility's bottom line and the rate-payer alike.  


The State of Colorado's Department of Natural Resources, Colorado Water Conservation Board (CWCB) is providing a comprehensive program of training and technical assistance for urban water systems across Colorado.  This program is part of a strategic objective from the Colorado Water Plan:  to support water management activities for all water providers.  The CWLI is structured and funded for the largest 165 water systems, though smaller systems may be considered if space is available.  The focus of the program will be the AWWA M36 water audit, the free AWWA Water Audit Software and associated WRF 4639 Level 1 Validation methodology.  CWCB has teamed with Cavanaugh and WSO to deliver this important program. 

The program will primarily include 4 work sessions spread out approximately over a 2-year period, beginning Spring of 2019.  Two of those work sessions will be at regional workshop locations (CEUs are anticipated), and 2 work sessions will be conducted remotely with shared screen.  Utilities are encouraged to include staff responsible for these areas:

                 Supply metering / Customer metering / Billing Management


The program is structured with 2 tracks, to accommodate utilities who already have experience with the AWWA M36 water audit, as well as those who are new to it.  Advanced validation & analysis  may be available to a small number of utilities, depending on utility readiness and CWLI budget availability.   

The first step is to simply register.   For information on what each stage includes and schedule, please check out the Program Stages Overview page and be sure to check back regularly for updates.
