A Proposed Framework for Regulating Direct Potable Reuse in California
About the FrameworkThe State Water Board staff is preparing the Framework to satisfy the recommendation in Assembly Bill (AB) 574 (Chapter 528, Statutes of 2017) to establish a framework for the regulation of potable reuse projects on or before June 1, 2018. In preparing the Framework, the State Water Board will include the following elements stated in the California Water Code section 13560.5:
- The consideration of recommendations provided in the State Water Board’s “Investigation on the Feasibility of Developing Uniform Water Recycling Criteria for Direct Potable Reuse.”
- A schedule for completing the recommended research described in “Investigation on the Feasibility of Developing Uniform Water Recycling Criteria for Direct Potable Reuse.”
- A regulatory framework for potable reuse projects that will be protective of public health.
- A process and timeline for updating uniform water recycling criteria for potable reuse through reservoir water augmentation.
The Framework is intended to primarily document and communicate the State Water Board Division of Drinking Water’s (DDW) current thinking on regulating direct potable reuse in California. The feedback received from the public will help inform the State Water Board in laying the groundwork for the development of the uniform water recycling criteria for direct potable reuse. The Framework is not a regulatory document. A rulemaking process pursuant to the Administrative Procedure Act will be a separate effort undertaken by the State Water Board for the uniform water recycling criteria for direct potable reuse through raw water augmentation.
The Framework and Fact Sheet can be downloaded from web links below.
State Water Board DDW staff will be holding workshops in northern California and southern California to present the Framework. The workshops are open to the public. Please see Workshop Notice for details regarding the workshop. Pre-registration is not required. A sign-in sheet will be available at the workshop locations.

State Water Board is voluntarily soliciting public comments on the Framework. Written public comments will be requested in two rounds. The initial 30-day public comment period is set up so DDW staff can receive early feedback on the Framework concepts, primarily related to regulation of direct potable reuse projects. The public is welcome to submit comments regarding the Framework after the close of public comment period. DDW staff will review all comments received, but may not be able to provide an individualized detailed response.
