Project supporters

Similar wastewater reclamation projects were proposed in neighboring Los Angeles and San Diego counties in the 1990s, but never came to fruition because the issue got politicized and wrongly labeled "toilet to tap." The Orange County Water District (OCWD) and Orange County Sanitation District studied these projects carefully before embarking on the ambitious and visionary GWRS project.

Through extensive research, which included numerous surveys, both agencies developed and executed an aggressive outreach plan to educate the general public within Orange County and beyond about the real facts of wastewater purification. Outreach included more than 2,000 presentations throughout the community. Transparency and having over 25 years of proven water quality data from OCWD's Water Factory 21 (1976-2004), which purified wastewater for injection into OCWD's seawater barrier, were critical to solidifying support and earning the public's trust of the GWRS. As a result, the GWRS has received broad support from the health, scientific, environmental and water quality communities, as well as from chambers of commerce, service organizations, educational institutions and local, state and federal leaders, and policy makers.

The Community

  • Edmund G. Brown Jr., Former Governor, State of California

    "As California’s drought persists, Californians must use water thoughtfully and local water agencies must protect precious water supplies. The expanded Groundwater Replenishment System, constructed by the Orange County Water District, represents an excellent example of local leadership, innovation, sound planning and investment that have given north and central Orange County an advantage during our current drought crisis. This project will provide enough drinking water for 850,000 people by reusing water more than once. On behalf of the state of California, I would like to congratulate the Orange County Water District and Orange County Sanitation District on the expansion of the Groundwater Replenishment System. I invite all Californians to practice more sustainable water practices demonstrated by the Orange County Water District." (June 2015)

  • Arnold Schwarzenegger, Former Governor, State of California

    "California’s economic and environmental future is enhanced by our ability to maximize precious resources. The GWR System is an environmentally responsible approach for securing alternative sources of water. It increases Orange County’s water independence by creating a drought-proof supply of safe, clean water. I commend you for your ingenuity in promoting water efficiency and conservation. Your efforts save energy, minimize wastewater released to the Pacific Ocean and help sustain healthy water resources for future generations." (Oct., 2004)

  • Loretta Sanchez, Former U.S. Representative, (CA-47th District)

    "Orange County is susceptible to severe water shortages due to recurring droughts and dramatic population growth. Reusing recycled wastewater is a smart strategy that has helped protect our community, and our environment, from periodic water shortages. I am proud to introduce H.R. 5039, which will help ensure Orange County’s water supply is clean, safe, and secure for years to come. Currently, about half of Orange County’s water supplies come from outside the county. Expanding the GWRS will allow Orange County to produce its own water without the political, environmental, and legal issues that come with importing water from Northern California and the Colorado River. For the first time, our community has a chance to be truly independent – the manufacturer and consumer of its own water supplies." (April 2010)

  • Barbara Boxer, Former U.S. Senator, California

    "I am delighted to have worked on behalf of the Orange County Water District to obtain funding for the Groundwater Replenishment System.
