Consistent with our mission to meet the region’s needs for reliable, high quality, and affordable water, Upper District continues to work with other water agencies to ensure that the San Gabriel Valley has a safe water supply. In light of the growing concern over the presence of emerging contaminants known as PFAS, below are fact sheets, briefing materials and visuals that may be helpful when answering questions about these chemicals.
The Upper San Gabriel Valley Municipal Water District (Upper District) is celebrating six decades of innovation, conservation, and good water management. Upper District was formed by the voters on December 8, 1959 to help sustain adequate imported water supplies for the rapidly growing San Gabriel Valley.
Upper District’s Board of Directors held their first meeting on January 7, 1960 in Temple City. For the past 60 years, we have played a vital role in supplementing local water supplies with imported water from the State Water Project and replenishing the Main San Gabriel Groundwater Basin. Today, Upper District has taken a leadership role in educating the public on their local water supply and the benefits of long-term, sustainable water efficiency practices.
It is with this in mind that Upper District is proud to release our new water supply educational video for public use. We take great pride in the collaborative work that the local water agencies undertake to manage the Main San Gabriel Groundwater Basin. Thanks to several key local, regional and federal agencies in the water community, every time you turn on the faucet you are tapping into a complex water delivery system.
So, where does our water supply come from?

Phillip D. Hawkins was seated today as a member of the Metropolitan Water District’s Board of Directors.
Hawkins returns to Metropolitan’s 38-member board, where he has represented Central Basin Municipal Water District for four different terms at various times between 2003 and February 2019. Hawkins follows Frank Heldman, who joined the board in March 2019. He will serve on the board’s Audit and Ethics and Finance and Insurance committees.
Hawkins was re-elected to his fifth term on Central Basin’s board in November 2016, representing the cities of Artesia, Bellflower, Cerritos, Hawaiian Gardens, Lakewood, Paramount and Signal Hill. He chairs the Central Basin Administration & Ethics Committee and actively participates in the Colorado River Water Users Association, the Urban Water Institute and the California Contract Cities Association.
The Metropolitan Water District of Southern California is expanding its effort to learn more about the water supply potential of local stormwater capture with a new $7.5 million pilot program approved today by its board of directors.
By funding construction of new stormwater projects and installation of monitoring equipment on existing ones, the program will gather data on the amount of water produced by projects that capture local rainfall and stormwater runoff and use it to recharge groundwater basins in the region.
“This could mark the beginning of a host of new local supply opportunities for Metropolitan and our member agencies,” board Chairwoman Gloria Gray said. “Metropolitan is always exploring new, better and more efficient ways to maintain reliability for Southern California, so we are excited to find out just how much potential there is for stormwater capture.”
Jeffrey Kightlinger, general manager of the Metropolitan Water District of Southern California, issues the following statement on the release of new federal biological opinions to manage the operations of the Central Valley Project and State Water Project:
“It is beyond time to update these guidelines from those that were developed over a decade ago. These opinions advance the much-needed approach of managing the Delta based on real-time conditions and real-time monitoring of important fish species. Undoubtedly there are times when fish need greater protections, and pumping must be reduced, in order to protect the species in key migratory moments. There are also times when public water agencies can safely divert supplies when the populations are out of harm’s way. While this creates some uncertainty about our future supplies, it is without question a better approach.
CARSON—In a major step toward the potential construction of one of the largest water
recycling plants in the nation, the Metropolitan Water District of Southern California and the
Sanitation Districts of Los Angeles County were joined today by federal, state and local water leaders
to celebrate the start of operations at the Regional Recycled Water Advanced Purification Center.
The 500,000-gallon-per-day demonstration facility takes cleaned wastewater from the
Sanitation Districts’ Joint Water Pollution Control Plant and purifies it using an innovative process
that could significantly improve efficiencies and reduce costs in water recycling.
Over the next 15 months, Metropolitan will put this treatment process through rigorous testing
to ensure the process effectively removes impurities and the resulting water meets the highest quality
standards. The testing and other analyses will help the agencies determine whether to grow the
facility to a full-scale plant that could potentially produce up to 150 million gallons of purified water
daily – enough to serve more than 500,000 homes and industrial facilities.
“Today marks a key step in Metropolitan’s endeavor to directly develop a drought-proof local
water supply for millions of Southern Californians,” said Metropolitan Board Chairwoman Gloria D.
Gray. “Over the last two decades, Metropolitan has steadily diversified the region’s water supply
portfolio and prepared for a changing climate by investing in conservation and local supply projects.
Metropolitan is now scaling that commitment up to a higher level.”
Congresswoman Grace Napolitano, State Water Resources Control Board Chairman Joaquin
Esquivel and Los Angeles Regional Board Chairwoman Irma Muñoz joined Metropolitan and the
Sanitation Districts in celebrating the launch of operations.
