Wastewater Needs Assessment

The Water Boards Wastewater Needs Assessment (WWNA) is a four-year project, beginning July 2023, to provide information on California’s wastewater sanitation system needs. The WWNA an outcome from 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. The WWNA intends to provide:

  • a statewide list of wastewater infrastructure priority projects for potential funding sources, and
  • the first statewide gap analysis of wastewater infrastructure to inform Water Board and state decisions on regulatory and resource investment priorities.

For more information, please read the one-page WWNA project description / descripción del proyecto de la WWNA.
