Division of Drinking Water's Recycled Water Information
- Office of Administrative Law approved the proposed Surface Water Augmentation regulations and filed the regulations with the Secretary of State. The regulations will be effective on October 1, 2018. Approved regulation text is available.
- Information on public hearings for the City of San Diego’s proposed surface water augmentation project is available
- State Water Board will continue to accept public comments on the Framework for Regulating Direct Potable Reuse in California.
- State Water Board adopted a resolution for the Surface Water Augmentation regulations at its March 6, 2018, board meeting
- 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.

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 (1) adopt regulations regarding surface water augmentation (SWA), a form of indirect potable reuse (IPR), and (2) submit a report to the legislature on the feasibility of developing uniform water recycling criteria for direct potable reuse by December 31, 2016.
- To assist in these activities, we've appointed an Advisory Group and an Expert Panel.
- The Report to Legislature was submitted on December 29, 2016. A copy of the Report and more information are available here.
- The public comment period for for draft SWA regulations is now closed. The comment letters received are available here. Draft regulation text and instructions on how to submit public comments or attend public hearing are available here. We prepare a list of frequently asked questions (FAQs) about the SWA regulation. The FAQs document is available here.

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.
