Recycled Water: Regulations and Guidance

Last Update: January 13, 2012

Draft Regulations:  Groundwater Replenishment with Recycled Water

• Draft Regulations for Groundwater Replenishment with Recyced Water (PDF) (dated November 21, 2011) are now available, as part of the process of developing a final proposed version of the regulations.
• NOTE DATE CHANGE:  We are requesting informal written comments on the draft regulations.  Please email your comments to Mike McKibben no later than February 29, 2012.
• 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.  
• Click here for frequently asked questions (FAQ) related to the draft regulations.
• Workshops on the Draft Regulations: In December 2011 CDPH held three workshops (PDF)to provide an overview of the draft regulations. 
  Slides for the workshops:  Introduction and Background (PowerPoint) or  ...(PDF); Regulations/Criteria (PowerPoint, 1.7MB) or ...(PDF); and Implementation (PowerPoint) or ... (PDF)
  Workshop video:  Part 1 (WMV, 44MB); Part 2 (WMV, 50MB); Part 3 (WMV, 47MB); Part 4 (WMV, 17MB);
