Water is the lifeblood of Orange County and without high-quality and reliable water, no community and no sector of the economy – from high tech to manufacturing to agriculture – can thrive or expand.
Dedicated teams of planners, engineers, water quality specialists, technicians, and other water professionals have built and maintained the systems to guarantee that when your tap is turned on, good, clean water flows freely and abundantly.
California Water Professionals Appreciation Week, Oct. 3-11, 2020, is an exciting occasion to showcase the ‘people behind the pipes’ throughout the state and an opportunity to highlight rewarding careers in the water industry and cultivate the next generation of water leaders.
I would like to thank all of the 225 employees at the Orange County Water District (OCWD; the District) who deserve recognition not only during this week, but every day. Read More…

Joined by leadership from the Orange County Water District (OCWD; Water District) and Orange County Sanitation District (OCSD; Sanitation District), U.S Environmental Protection Agency (EPA) Administrator Andrew Wheeler toured the Groundwater Replenishment System (GWRS) on Sept. 3, 2020, where he announced a joint effort that will save ratepayers $79.4 million. Officials from EPA and the Water District made this savings possible by updating a Water Infrastructure Finance and Innovation Act (WIFIA) loan that was granted to OCWD for use toward the construction of the GWRS Final Expansion.
In 2018, EPA granted a $135 million WIFIA loan to OCWD to help finance the 30-million-gallon-per-day (MGD) final expansion of the GWRS, a $282 million project. The initial 70 MGD GWRS project came online in 2008, followed by a 30 MGD expansion in 2015. The second and final expansion of the GWRS will make the world’s largest reuse project even bigger, taking it to its ultimate capacity of 130 MGD ― enough water to meet the daily needs of 1 million people.

On Sept, 1, 2020, the U.S. Environmental Protection Agency (EPA) announced the addition of the Orange County North Basin Site (the Site) to the National Priorities List (NPL), sometimes referred to as the Superfund List. NPL listing serves as the basis for prioritizing EPA Superfund cleanup funding and enforcement actions. The Site includes parts of Anaheim, Fullerton and Placentia, and is part of the larger Orange County Groundwater Basin (Basin) managed by the Orange County Water District (OCWD; the District). The Basin is a regional asset that provides up to 77% of the water for 2.5 million residents in north and central Orange County. Read More…
The Orange County Water District (OCWD; the District) did its part to save energy during August and September heatwaves by voluntarily reducing its electricity use. The Groundwater Replenishment System (GWRS), created by OCWD and the Orange County Sanitation District, is the world’s largest water reuse project. It is managed by OCWD. By temporarily lowering water production of the GWRS to 15 million gallons per day, OCWD reduced its daily electricity use from an average of 17 megawatts to five megawatts, saving 150 megawatts hours of power over a five-day period, Aug. 14-18, and saving 50 megawatt hours of power over a two-day period, Sept. 4 and 5.
“We’re committed to doing the right thing for the 2.5 million people in our service area and our actions often transcend water. As a member of the Orange County community we were proud to do our part to help free up much needed power for Orange County residents, and the region, during recent triple-digit temperatures,” said OCWD President Vicente Sarmiento.

Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are chemicals that are prevalent in the environment and were once commonly used in many consumer products. They are part of a larger group referred to as per-and polyfluoroalkyl substances (PFAS). Due to the prolonged use of PFOA and PFOS, the chemicals are now being detected in the environment, including water sources throughout the United States.
PFAS have been detected in the Orange County Groundwater Basin. OCWD provides regular PFAS updates to community stakeholders to inform them of the proactive measures that the District and retail water agencies are taking to address PFAS in the Basin.
For more background information and the newest monthly update visit September Update.
For additional information, please visit OCWD’s PFOS/PFOA Resources page.
The Nuts & Bolts column features OCWD construction updates each month. This month’s column features the Groundwater Replenishment System (GWRS) Final Expansion.
Principal Scientist Ken Ishida’s published study, in collaboration with Trojan Technologies, was selected as one of the top 10% of recent papers in Environmental Science: Water Research & Technology, based on the exceptionally positive referee reports received during peer review along with the editor’s assessment of the significance and impact of the paper. The paper is titled “UV/chlorine vs. UV/H2O2 for water reuse at Orange County Water District, CA: a pilot study.”
As part of its standard to forge and maintain long-term, positive and proactive relationships with members of the local community and greater water industry and to be transparent about its operations and programs, OCWD board members and staff speak regularly before groups and at events. We recently participated in the following virtual events:
• Following introductory remarks from Director Tri Ta, Chief of Hydrogeology Roy Herndon provided an update to the Seal Beach City Council on OCWD's Sunset Gap Seawater Intrusion Investigation and proposed monitoring well pair at Gum Grove Park parking lot.
• Dr. Megan Plumlee, director of research, spoke during WES 2020 about OCWD's PFAS pilot study. The conference was hosted by the CA-NV division of American Water Works Association (AWWA).
- • Dr. Plumlee also presented findings from the PFAS Treatment Study to the city of Anaheim for consideration in its design of PFAS treatment systems for impacted drinking water production wells.
- • Exec. Dir. of Planning & Natural Resources Greg Woodside gave a presentation on the Prado Forecast-Informed Reservoir Operations (FIRO) at a Scripps-hosted virtual workshop on FIRO.
