South Orange County is heavily reliant on imported water, with the price of that water continuing to rise. Without readily available water to help the area through emergency situations, water districts serving South Orange County residents such as South Coast Water District and Moulton Niguel Water District are looking to diversify their water supplies with ocean water desalination and direct potable reuse.
The San Diego County Water Authority will host water leaders from throughout Southern California March 15 for the monthly meeting of the Colorado River Board of California. On March 14, before the formal meeting, CRB board members will tour projects in the region that promote water resiliency.
The CRB will consider the complex water supply issues facing the Southwest U.S. during its meeting. San Diego Congressman Scott Peters is also scheduled to address the CRB.
The tour is part of a new program implemented by CRB, under the leadership of Chair JB Hamby, Imperial Irrigation District’s representative, and Vice Chair Jim Madaffer, the Water Authority’s representative and Water Authority board member, to build greater awareness of each CRB member agency’s efforts to serve their region and manage their river supplies.
“The Colorado River Board is so important to ensuring California’s voice is heard on the river, especially during these difficult times as we work to find collaborative solutions to the river’s challenges now and into the future,” Madaffer said. “We look forward to showcasing the local supply projects, online now and planned, that create water resiliency locally, but that also reduce the demand on the river.”

Established in 1937, the CRB is a state agency tasked with protecting the interests and rights of the state and its agencies in water and power resources from the Colorado River.
The Water Authority is a member of the CRB along with IID, the Metropolitan Water District of Southern California, the Coachella Valley Water District, the Palo Verde Irrigation District, the Los Angeles Department of Water and Power, the California Department of Water Resources, and the California Department of Fish and Wildlife. CRB representatives, including two additional members from the public, are appointed by the Governor.

The CRB represents California in discussions and negotiations with the Basin states, the U.S. Bureau of Reclamation, governmental agencies at all levels, tribes, and Mexico regarding the management of the river.
CRB members on the tour will see two local water supply projects generating water now – the Claude “Bud” Lewis Carlsbad Desalination Plant – and planned – the East County Advanced Water Purification Plant.
The seawater desalination plant, the largest in the nation, came online in 2015 and recently passed the milestone of producing more than one-billion gallons of water for the San Diego region.

“The desalination plant is not only important to our region, but the Water Authority believes the plant could be part of an overall long-term solution to support Lake Mead, California’s critical river reservoir, under a proposal we are considering to expand the plant,” said Madaffer.
Now under construction, the East County Advanced Water Purification facility, or East County AWP, is a collaborative partnership between two Water Authority member agencies, the Padre Dam Municipal Water District and the Helix Water District, and the County of San Diego and City of El Cajon.
The plant is projected to generate a local, reliable and drought-proof drinking water supply utilizing state-of-the-art technology to recycle and reuse the region’s wastewater. The East County AWP is expected to produce 30% of East San Diego County’s water supply by early 2026, and is one of the innovative water purification facilities in the county either in operation or in development.
Scheduled to be operating in 2026, the East County AWP is projected to generate up to 11.5 million gallons per day of purified water— meeting approximately 30% of current drinking water demands for East San Diego County residents and businesses. Photo: San Diego County Water Authority
Following the facility tours on March 14, the CRB will hold its monthly meeting March 15 at the Water Authority’s Kearny Mesa headquarters in San Diego. The meeting is scheduled to start at 10 a.m. and is open to the public.

(Editor’s note: The Helix Water District and Padre Dam Municipal Water District, are two of the San Diego County Water Authority’s 24 member agencies that deliver water across the San Diego County region.)
In the parched Colorado River basin, water managers are turning over every stone looking for ways to keep the taps flowing. Now, they’re finding more water in some unusual places – shower drains and toilet flushes.
At a sprawling sewage treatment plant in Carson, California, the occasional breeze delivers a pungent whiff of a reminder of how used water becomes “reused.” Here, the Metropolitan Water District of Southern California is planting the seeds for a massive new facility, where a multi-billion-dollar installation could help recycle wastewater and keep drinking supply flowing for the agency’s 19 million customers.
Two things are true about the cost of water in San Diego: the cost of bringing water here and maintaining the system that does it is rising, but the amount of water San Diegans consume is dropping.
In 1990, the average San Diegan used 235 gallons of drinkable water per day, according to the Water Authority’s records. By 2021, San Diegans cut that almost in half to 130 gallons per day. Megadroughts that triggered mandatory water cutbacks triggered better water conservation habits, which stuck.
But while San Diegans are using less, the costs they pay continue to rise. The cost of San Digeo’s water supply is expected to rise anywhere from 5.5 to 10 percent beginning in 2023, with hefty hikes continuing in the years thereafter.
“Long after I’m dust, these supplies will be valuable to this region,” said Gary Arant, who leads the Valley Center Municipal Water District, of the haul of water rights San Diego has locked up. “Right now, we’ve got a lot of water. It’s expensive, but I think the decisions we made were good.”
Now that Gov. Gavin Newsom’s administration has released a final California Water Resilience Portfolio, farm organizations say they will monitor progress on implementing the plan’s proposals—and on resolution of ongoing state-federal conflicts that complicate achieving some of its goals.
Farm organizations welcomed a new water planning document from state agencies while they analyzed the document’s proposed strategies.
Titled the California Water Resilience Portfolio and released last week, Gov. Gavin Newsom’s administration described the document as an effort to guide water management in a way that works for people, the environment and the economy.
California is at a water crossroads.
We can continue our costly, 100-year-old pattern of trying to find new water supplies, or we can choose instead to focus on smarter ways of using – and reusing – what we already have.
The cheapest water is the water we save.
How will climate change affect California water management, and what steps should the state take to prepare for these changes? The PPIC Water Policy Center was asked by the Newsom administration to submit formal comments outlining key water policy priorities for the state—and ways to integrate actions across state agencies to implement these priorities. Our recommendations will inform the administration’s preparation of a water resilience portfolio. We address two key areas where the state can play a leading role—modernizing the water grid and protecting freshwater ecosystems.
This region has made tremendous strides toward diversifying its water portfolio. In Riverside County, groundwater desalination is moving forward to take full advantage of all available sources of water. Plans for Water Banking, which will take Northern California water imported during wet years to restore local aquifers for use during dry years, are also progressing.
State officials Thursday toured San Diego County water infrastructure to get a first-hand look at the region’s successful water portfolio approach for supply diversification.
California Natural Resources Agency Secretary Wade Crowfoot, Deputy Natural Resources Secretary Thomas Gibson, State Department of Food and Agriculture Secretary Karen Ross, and State Water Resources Board Chair E. Joaquin Esquivel were here to assess the region’s water projects as part of their new role in developing a water portfolio strategy for the state.
“The region is proof that the portfolio approach works,” said Water Authority Board Chair Jim Madaffer. “The Water Authority and its 24 member agencies continue to develop local projects and explore opportunities that would benefit the region, the state, Mexico and the Southwest.”
At a luncheon meeting and panel discussion at University of California, San Diego following the tour, the agency officials joined a group of more than 150 people to hear how the portfolio approach can help California and the Southwest meet water supply challenges.
Along with the Water Authority Board of Directors, elected officials, business, community and state and local leaders gathered in an auditorium at the Southwest Fisheries Science Center on the La Jolla campus.
“The state needs to look at a global approach to managing water,” said Water Authority Board Chair Jim Madaffer.
Madaffer said during the meeting that San Diego’s portfolio approach has been successful in increasing the region’s water supply reliability through diversification and innovation.
“The Water Authority’s model is one that can be replicated across the state to help ensure a secure water future for all Californians,” said Madaffer.
State agency leaders echoed Madaffer’s comments.
“San Diego has been a leader in the water portfolio approach,” said Wade Crowfoot. “We have to make the investments to build regional water resilience as part of the Governor’s order to develop a portfolio to manage water in California.”

The Water Authority invited the officials to visit after Gov. Gavin Newsom issued an Executive Order in April, directing state agencies to “prepare a water resilience portfolio that meets the needs of California’s communities and environment through the 21st century.”
In his May letter to Newsom, Madaffer thanked the governor for the “wisdom and leadership” with the issuance of Executive Order N-10-19, and invited the governor to tour San Diego County’s cutting-edge water facilities.
Newsom’s order also directed his administration to “identify and assess a suite of complementary actions to ensure safe and resilient water supplies, flood protection and healthy waterways for the state’s communities, economy and environment.”

The California Natural Resources Agency, the California EPA, and the California Department of Food and Agriculture, in consultation with the Department of Finance, were directed by Gov. Newsom to, among other tasks, “identify key priorities for the administration’s water portfolio moving forward.”
“Governor Newsom wants us to think long and broadly on water,” said Crowfoot. “He wants us to get away from the silos and conflicts on water in California – the mindset of environment groups versus farmers, north versus south, urban versus rural – and work together on water resiliency.”
“San Diego is a great example of the challenges and complexities of managing water supply, as we look to supercharge water resiliency in California,” said E. Joaquin Esquivel, Chair, Calif. State Water Resources Control Board, after a tour of water infrastructure. #cawater pic.twitter.com/t0SCcHLyGt

“The Water Authority and its 24 member agencies have made significant investments in the last two decades to diversify our water supply, creating a portfolio of resources to support our region’s 3.3 million people and $231 billion economy,” said Madaffer.
During the tour, the officials got a first-hand look at some of those investments, including the San Vicente Reservoir, Olivenhain Reservoir, and the Claude “Bud” Lewis Carlsbad Desalination Plant.

Scripps Institution of Oceanography research meteorologist Dan Cayan told the audience that temperatures and dry spells will increase in California in the future, making water storage, conservation, and forecasts even more critical.
“Global warming climate models show the Sierra Nevada snow pack will be 50% less in 2090 than today’s average April 1 snowpack,” said Cayan.

Cayan said observations and climate model projections indicate climate change is occurring and will grow stronger. California should expect 1.5-2 degrees Fahrenheit warming by 2050, he said.
Water Authority Assistant General Manager Dan Denham described a new study that will explore the viability of a regional pipeline to transfer water from the Colorado River to benefit multiple users in San Diego County and across the Southwest.
The pipeline system is one of a handful of ideas being discussed by San Diego County water leaders to enhance partnerships and solutions that make sense locally and more broadly as part of Governor Newsom’s Water Portfolio Program to develop resiliency statewide.
Map indicates three potential routes for a proposed regional pipeline system that would move Quantification Settlement Agreement water directly from the Imperial Valley to San Diego. Two of the routes (the light blue and purple lines) follow a southern route. The third proposed route, (shown in both a yellow and darker blue line) follows a northern path. Graphic: Water Authority
Creating a pipeline to transfer Colorado River water to the San Diego region has been studied periodically over decades.
But the new study is focused on how a regional pipeline could provide multiple benefits as part of a long-term water management strategy for California and the Southwest.
The expanded review will consider a system that could create much-needed storage opportunities for the Imperial Irrigation District that could support agriculture while addressing critical issues like the Salton Sea and the need for more renewable energy development.
