Recycled Water Research

The State Water Board is working with members of the recycled water community to identify knowledge gaps regarding specific topics in recycled water research, including potable and non-potable applications, to better understand recycled water research funding priorities. The Water Quality, Supply, and Infrastructure Improvement Act of 2014 (2014 Bond Law, Proposition 1) provides grant and low interest financing for water recycling projects. The State Water Board may dedicate up to two percent of the Proposition 1 funding allocated to recycled water, as well as two percent of repayments from Proposition 1 funded water recycling construction loans, to recycled water research and development as set forth in section 79144 of the Water Code. The availability of Proposition 1 funding has provided the State Water Board with the opportunity to continue to advance recycled water research to ensure recycled water is protective of the environment and human health.

  • NEW! Request for Proposals (RFPs) have been released for four (4) research studies funded through Grant Agreement No. D1705003. See "Requests for Proposals" tab for more details (December 12, 2018)
