ACWA Submits Comment Letter on Direct Potable Reuse Framework by Caroline Minasian Oct 15, 2019 Water News ACWA recently submitted a comment letter in support of the State Water Resource Control Board’s draft second edition of ‘A Proposed Framework for Regulating Direct Potable Reuse in California’. ACWA recognizes the importance of and need for increased recycled water in California. ACWA anticipates that once finalized, the second edition Framework will align with the administration’s Water Resilience Portfolio. Members interested in reading the comment letter can find it on ACWA’s website. Background Direct potable reuse (DPR) refers to recycled water that is introduced directly into a distribution system without the need for an environmental buffer such as a reservoir or groundwater aquifer. The first edition of the DPR framework was prepared to satisfy AB 574, which recommended a framework for the regulation of potable reuse projects. The State Water Board included the following elements from California Water Code section 13560.5 in the first edition of the DPR Framework: 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 draft second edition Framework includes updates on the regulatory approach for Direct Potable Reuse (DPR), considerations of drinking water treatment plants, a new subsection on aesthetic issues and clarification of terminology. The draft second edition Framework can be viewed online. For questions about the comment letter, please contact Regulatory Advocate Melissa Sparks-Kranz at (916) 441-4545.
