This project produced a direct potable reuse (DPR) guidance framework that water utilities and regulators can use to evaluate the safety of existing or potential future DPR scenarios and help facilitate a proactive DPR monitoring process that is protective of public health. This framework includes practical guidance for selecting and implementing monitoring and control tools for DPR. Published in 2019.

A literature review was completed in 2016 and is posted below under Project Papers.

Research partners: Alameda County Water District, East Bay Municipal Utility District, Contra Costa Water District, Los Angeles Department of Water & Power, San Francisco Public Utilities Commission, and Zone 7 Water Agency.
