Wastewater Needs Assessment

The Water Boards Wastewater Needs Assessment (WWNA) is a four-year assessment project, beginning July 2023, to provide information on California’s wastewater sanitation system needs. This is an outcome from adopted State Water Board Resolution No. 2022-0019 and Resolution No. 2016-0010, recognizing Californians’ equal and human right to sanitation and that safe wastewater management is critical to human and environmental health.

The WWNA does not impose any permitting requirements, consolidation projects, or fees for regulatory or governing agencies, businesses, or peoples of the public.

This page will be periodically updated to provide reports and WWNA updates.
