Senate Bill 555 requires all urban retail water suppliers in California to submit a validated water loss audit to the California Department of Water Resources. Last year, the validation requirement was fulfilled by the Water Loss Technical Assistance Program (Water Loss TAP), which was funded by the State.
However, since there was not an extension of the Water Loss TAP, urban retail water suppliers submitting water loss audits in 2018 must fulfill the validation requirements through one of two methods per DWR’s Validated Water Loss Audit Reporting Regulations:
- Have the validation completed by an individual who can demonstrate he or she has conducted water loss audits in accordance with the method specified in Section 638.2, and has conducted a minimum of 10 Level 1 audit validations in accordance with the Water Research Foundation Level 1 Water Audit Validation: Guidance Manual 4639A
(This option will likely require the hiring of a technical expert consultant),
- Have the validation completed by an individual certified by the CA-NV AWWA as a water audit validator.
After July 1, 2019, the validations can only be completed by an individual certified by the CA-NV AWWA as a water audit validator. Any interested person (such as utility staff or consultants) can apply to receive the certification. (Note: The validator cannot not be involved in the preparation of the audit.)
