Division of Drinking Water's Recycled Water Information
- State Water Board delivers Report to Legislature on the Feasibility of Developing Uniform Water Recycling Criteria for Direct Potable Reuse
- State Water Board adopted the Water Reclamation Requirements for Recycled Water Use (General Order) at its June 7, 2016 board meeting.
- Regulations for groundwater replenishment using recycled water became effective on June 18, 2014. They've been incorporated into Recycled Water-Related Regulations at the Division of Drinking Water's Law Book.
- Follow these links for information on the Advisory Group and the Expert Panel.
Statutes and Regulations
- Compilations of current statutes and regulations related to recycled water are available at the Division of Drinking Water's Law Book, which also includes laws related to drinking water.
- Current Cross Connection regulations are included in Recycled Water-Related Regulations, under Title 17 of the California Code of Regulations. Revisions of these regulations are being developed.
Among the statutes related to recycled water are Water Code sections 13560-13569, which require us to:
- Adopt regulations for groundwater replenishment using recycled water by June 30, 2014. The regulations, which became effective June 18, 2014, are available here.
In addition, we are required to
- Adopt regulations regarding surface water augmentation (SWA), a form of indirect potable reuse (IPR):
- Water Code section 13562 requires the State Water Board to adopt uniform water recycling criteria for SWA on or before December 31, 2016, if an Expert Panel has made a finding that the proposed criteria (regulations) would adequately protect public health. The Expert Panel provided on-going feedback during the development process for the SWA regulations. The Expert Panel involved with SWA regulations also developed a report with its findings and recommendations regarding the feasibility of developing criteria for direct potable reuse (DPR), which is included in the State Water Board’s report to legislature.
- Health and Safety Code section 57004 requires a regulation proposed for adoption by the State Board to undergo an external scientific peer review of the bases of the scientific portions of the regulation. The scientific peer reviewers were independent of the Expert Panel.
- The State Water Board received the completed scientific peer review on June 10, 2016. When available, documents related to the scientific peer review may be found here.
- The scientific peer reviewers were supportive of the draft SWA regulations; however, their comments resulted in revisions to the draft SWA regulations. The revised draft SWA regulations were subsequently provided to the Expert Panel in order to obtain the Expert Panel’s finding as to whether the draft SWA regulations would adequately protect public health. The Expert Panel recently made a finding that the draft SWA regulations would be protective of public health.
- The State Board is currently completing final reviews and the development of the remaining elements of a regulatory package, as required by the Administrative Procedure Act before posting the draft SWA regulations for public comment. Currently, the State Water Board anticipates the release of the proposed SWA regulations for public comment and a public hearing in the first quarter of 2017.
- Submit Report to the Legislature on the feasibility of developing uniform water recycling criteria for direct potable reuse by December 31, 2016.

Review of California's Water Recycling Criteria for Agricultural Irrigation - Recommendations of an Independent Advisory Panel (September 2012) (PDF, 2MB)
An Independent Advisory Panel, consisting of nine nationally recognized experts, reviewed California's Water Recycling Criteria for use in agricultural irrigation. This report reviews the use of water recycling for agricultural purposes, including food crop production, in order to address whether the use of recycled water, produced in conformance with California's Water Recycling Criteria, has been protective of public health.
BDOC as a Performance Measure for Organics Removal in Groundwater Recharge of Recycled Water - Final Report of the Independent Advisory Panel (September 2012) (PDF)
An Independent Advisory Panel, consisting of seven nationally recognized experts, reviewed the use of Biodegradable Dissolved Organic Carbon (BDOC) as an alternative to Total Organic Carbon (TOC) as a suitable performance measure to assess the removal of unregulated wastewater-derived organics from recycled water used for groundwater recharge via surface spreading. This report provides useful information for future proposals regarding BDOC as a performance measurement.
