CWCB Phase 1 announcement

Phase 1 of the CWLI kicked off in 2018 and was structured and funded for the largest 165 water systems, though smaller systems were considered if space was available.  The focus of the program was the AWWA M36 water audit, the free AWWA Water Audit Software and associated WRF 4639 Level 1 Validation methodology.  CWCB teamed with Cavanaugh and WSO to deliver this important program. 

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

                 Supply metering / Customer metering / Billing / Management

 

The program was structured with 2 tracks, to accommodate utilities who already have experience with the AWWA M36 water audit, as well as those who were new to it.  Advanced validation & analysis  was available to a small number of utilities, depending on utility readiness and CWLI budget availability.  For the full CWLI Phase 1 report, visit the CWCB Urban Water Efficiency page.
