Become a California Water Audit Validator

The Water Audit Validator course is a 3-day program designed to qualify individuals to perform Level 1 water audit validations in California. Water audit validators examine water loss audit inputs to consider the water audit's accuracy and document the sources of uncertainty. Per Title 23, Division 2, Chapter 7 Water Loss Control & Reporting urban retail water suppliers must submit validated distribution system water audits to the California Department of Water Resources each year. Individuals who successfully complete this course and exam will receive a Water Audit Validator certificate. This certificate is required to validate water audits.  The certificate will be valid for 3 years.
