Water Quality Control Policy for Recycled Water

Policy

The State Water Board recognizes the importance of recycled water as a critical water supply for California and is implementing the Recycled Water Policy, streamlining permitting for recycled water projects, and identifying and funding the highest priority research needs to ensure the state’s recycled water goals are achieved. The State Water Board adopted an amendment to the Recycled Water Policy on December 11, 2018 (effective on April 8, 2019), which includes numeric goals for the use of recycled water, two narrative goals to encourage recycled water use in groundwater-overdrafted and coastal areas, and annual reporting requirements statewide for the volume of recycled water produced and used as well as the volume of wastewater treated and discharged.

CEC Monitoring

All operating indirect potable reuse facilities must monitor for constituents of emerging concern (CECs) pursuant to Attachment A of the Recycled Water Policy. The CEC monitoring program was developed in accordance with recommendations from the 2018 Science Advisory Panel on CECs in Recycled Water.

A quality assurance project plan (QAPP) must be submitted by each facility in advance of beginning the CEC monitoring program pursuant to the Recycled Water Policy. Please email Tina Low at tina.low@waterboards.ca.gov for Word version of QAPP template.
