Recycled Water: Regulations and Guidance
Last Update: February 24, 2014
SB 918 (Pavley, 2010) and SB 322 (Hueso, 2013) (Water Code Sections 13560-13569 (PDF)) require CDPH, in consultation with the State Water Resources Control Board (SWRCB), to investigate and report to the Legislature on the feasibility of developing uniform water recycling criteria for direct potable reuse. To assist in this activity, CDPH, in consultation with SWRCB, has appointed an Advisory Group and is establishing an Expert Panel that will advise CDPH. The Expert Panel will also provide advice on developing criteria for indirect potable reuse through surface water augmentation.

- Advisory Group - its first meeting was on February 21, 2014 in Sacramento. At this meeting the Advisory Group consulted with CDPH on selection of members of the Expert Panel.

Draft Regulations: Groundwater Replenishment with Recycled Water
CDPH is developing regulations that address groundwater replenishment for aquifers designated as sources of drinking water using recycled water from domestic wastewater sources. In 2011, CDPH released revised draft regulations and held workshops throughout the state, and requested written comments from all interested parties. CDPH reviewed the comments and revised the draft regulations accordingly. Once adopted, these regulations would replace the existing regulations, which were adopted in 1978. CDPH is currently in the process of developing the remainder of the regulation package based on this latest draft. Follow this link for the June 26, 2013 draft regulations (PDF)
Water Code section 13562 requires CDPH to adopt revised groundwater replenishment regulations by December 31, 2013, and regulations for surface water augmentation by December 31, 2016. Given the time required for the intital steps of the formal regulation adoption process, the groundwater replenishment regulations are expected to be proposed in 2014. In the meantime, proposed projects for groundwater replenishment (and surface water augmentation) continue to move forward.
The final proposed version will proceed through the formal regulation adoption process and will be subject to public review and comment as part of that process.
