The San Diego County Water Authority’s First Aqueduct will be shut down periodically over the next four months for maintenance projects to ensure a safe and reliable water supply for the region. A series of three shutdowns on the First Aqueduct is scheduled from December through March, when portions of the aqueduct will be relined, along with other maintenance.
The Water Authority and its member agencies are coordinating to minimize impacts to residents and businesses, while servicing pipelines that are more than 65 years old.
Customers of these affected retail agencies during the Dec. 5-14 shutdown should check with their local water utility if they have questions about localized impacts: Fallbrook Public Utility District, Rainbow Municipal Water District, Rincon del Diablo Municipal Water District, Vallecitos Water District, Valley Center Municipal Water District, Vista Irrigation District, and the Yuima Municipal Water District.
Proactive Asset Management Program
“Proactively managing our water delivery system in coordination with our member agencies ensures we continue to provide a safe and reliable supply that serves the region’s 3.3 million residents and our $240 billion economy,” said Eva Plajzer, the Water Authority’s director of operations and maintenance. “It requires an extraordinary amount of work each fall and winter during the shutdown season to take care of this critical infrastructure.”
Maintenance work on pipelines is scheduled during low-demand periods to minimize impacts on water service. The other scheduled shutdowns on the First Aqueduct are January 23 to February 1 and February 27 to March 8. The February 27 to March 8 shutdown will also impact the Helix Water District and the cities of San Diego, Poway and Ramona.
Historic First Aqueduct
The historic First Aqueduct was constructed in the 1940s with Pipeline 1 and in the 1950s with Pipeline 2. On November 28, 1947, the first Colorado River water flowed south from Riverside County for 71 miles into the City of San Diego’s San Vicente Reservoir via the First Aqueduct.

Asset Management Program
The Water Authority’s Asset Management Program is a key element of providing safe and reliable water supplies to the region. The agency continually assesses and inspects its 310 miles of large-diameter pipelines, which provide treated and untreated water to 24 member agencies in San Diego County. The program is widely recognized for pioneering work – including a patented inspection device – that promotes water affordability by avoiding costly unplanned disruptions in service.
As assets age, the Water Authority proactively replaces and repairs them to minimize impacts to member agencies and the public. Investments in the latest inspection technologies, including electromagnetic scanning, robotic inspections and 3D tunnel inspections help the Water Authority’s asset management team detect defects in pipelines and related facilities. Identifying potential issues early avoids more costly fixes later.

After three years of virtual events, the PPIC Water Policy Center’s annual fall conference made a welcome return to an in-person format in Sacramento on Friday, November 18. The half-day event began with a welcome from PPIC Water Policy Center assistant director Caity Peterson and a presentation by senior fellow Jeffrey Mount.
This year was “brutal” for agriculture, said Thad Bettner of the Glenn-Colusa Irrigation District during the first panel, moderated by PPIC Water senior fellow Alvar Escriva-Bou. “We took about 300 square miles out of production.” The drought hit rural and urban communities hard, too: Kyle Jones of the Community Water Center said that “over 1,300 [drinking water] wells went dry.” Bill Hasencamp of Metropolitan Water District described in vivid detail how once-reliable water management strategies are failing, in part due to a lack of interconnections: his agency had to restrict deliveries to “one-third of our service area despite having a record amount of dry-year storage reserves.”
Drought and climate change
The environment suffered as well, though Sandi Matsumoto of The Nature Conservancy praised the State Water Board, River Partners, and others for efforts to aid wildlife. Well-timed curtailments in some basins, she said, were helpful. But the stakes are high, she said: “Over half of California’s salmon and steelhead species are on a trajectory towards extinction.” And as Hasencamp put it, “drought and climate change have outstripped us.”
Sandra Kerl commended Scripps Institution of Oceanography for their “game-changing” atmospheric river forecasts—and panelists highlighted the promise of Forecast-Informed Reservoir Operations (FIRO) as a tool to make the most of storage infrastructure.

Reservoir storage capacity
Capturing more water during wet periods will help California weather the dry periods, said participants in the second panel, moderated by research fellow Andrew Ayres. Sandy Kerl of the San Diego County Water Authority said that investing in reservoir capacity was key after the county suffered a crippling drought in the late ‘80s. “We now have enough storage capacity…to sustain the population at a 75% service level for six months,” she said.
Socking water away in underground water banks is another important strategy, said Mike Tognolini of EBMUD. Such projects rely on good relationships. After some early missteps in a water banking pilot project, he said “we [now] have solid partnerships with local water agencies in San Joaquin County and, importantly…with growers in the region.”
Groundwater recharge and water banking
Aaron Fukuda of the Tulare Irrigation District emphasized the importance of trust-building too. “I tell everybody when you want to strike up a partnership, just take them out to dinner,” he said, to laughter. Groundwater recharge works best when relationships are formed first, and how you approach water right holders matters, he said. “When you ask a farmer for help, they will help.”
Kerl commended Scripps Institution of Oceanography for their “game-changing” atmospheric river forecasts—and panelists highlighted the promise of Forecast-Informed Reservoir Operations (FIRO) as a tool to make the most of storage infrastructure. Local agencies are also making good progress in accounting for water once it’s in the ground—key to facilitating more water banking projects.
And, as Julie Rentner of River Partners noted, the stakes for managing the increasingly flood-prone wet periods of our changing climate could not be higher. In 1997, the San Joaquin Valley was hit by a flood that broke the valley’s flood control system in 17 places. Climate projections show that a flood three to five times that magnitude “will likely hit the San Joaquin Valley in our lifetimes.” The damage, she said, would be incalculable. But California’s “new Central Valley flood-protection plan…takes a solid look at multi-benefit projects” that slow floods, recharge groundwater, and support habitat restoration.
‘Climate whiplash’
The day’s final panel looked at policy’s role in responding to climate conditions. PPIC Water Policy Center director Ellen Hanak sat down with California Department of Water Resources director Karla Nemeth, State Water Board chair E. Joaquín Esquivel, and US Army Civil Works Program assistant secretary Mike Connor. Hanak asked these policy heavy-hitters to share progress and gaps in “this moment of climate whiplash.”
“We’re now in a moment where it’s like ‘Everything, Everywhere, All at Once,’” said Karla Nemeth. “We’re in a multiverse….everything is moving.” Hotter temperatures have now become “their own water demand,” she said, and Californians need to embrace water recycling, desalination, recharge, and conservation—all while keeping water affordable. But California also needs to think big, she said. “We can’t be afraid of taking out big infrastructure or putting in big infrastructure.” As an example of the former, she noted progress on removal of the dams on the Klamath River. And for the latter, she noted that “the Delta conveyance project is enormously important to climate adaptation.”
Hydrology and resilience
Esquivel said that water projects that were state-of-the-art 50 years ago now find themselves “mismatched for the climate that we have.” While data has improved, “data alone is not enough. It has to turn into better decision making.” A “greater fidelity to reality,” he said, will be essential. He said compliance across multiple basins with water right curtailments is heartening. “People want to use rights in ways that help support the resilience of us all.”
Mike Connor shared that much of the country still struggles to understand how profoundly conditions have changed. In one eight-week period this summer, he said, “there were six one-in-one-thousand-year precipitation events across the continental US.” He said that “restoring hydrologic function wherever we can…always adds to water availability by keeping it in the system.” All panelists agreed that increased funding, including from the recently passed Inflation Reduction Act, will be a boon to efforts.

SAN DIEGO – Due to past rainfall and a state mandate with regard to water level, the City of San Diego is scheduled to release approximately 250 million gallons of water from Hodges Reservoir into the San Dieguito River. This will lower the current water level by approximately 2 feet. The water release, using valves in the dam, is scheduled to begin Monday, Nov. 28, 2022, and will continue for approximately two days until the reservoir elevation is approximately 275 feet.

Rincon del Diablo Municipal Water District reports that it completed an initiative to provide nearly $1.2 million in rebates to customers and has received overwhelmingly positive feedback about the program.
The rebates were made possible following years of litigation by the San Diego County Water Authority against the Metropolitan Water District of Southern California for violating existing exchange agreements between the two agencies. The customer rebates come as residents across the county prepare for the holiday season, giving Rincon Water customers a boost to help put food on the Thanksgiving table and some extra gifts for family members next month.
Water rebates to customers
“When the San Diego County Water Authority won their lawsuits against the Metropolitan Water District of Southern California, we had to decide on what to do with about $1.2 million that was returned to us,” said Clint Baze, General Manager of Rincon Water. “The Rincon Board of Directors said the decision was easy because the money belongs to our customers and that is where it should go. It was the right decision, and it reflects our values of integrity, transparency, and fiscal accountability.”
The Water Authority’s lawsuit against MWD resulted in the SDCWA disbursing over $90 million to 24 member agencies, including Rincon Water. The SDCWA suit was filed against MWD in an effort to remedy overcharges from 2011-2017.
Located in northern San Diego County, Rincon Water is an urban water district consisting of more than 8,600 metered connections, of which 89% are residential customers. Its industrial customers include companies ranging from a high-tech trauma hospital, a nationally popular brewery, and a large vital utility, among others.
Rincon Water delivers customer service to ratepayers
“We take our obligations to our customers seriously – in this case, it meant returning the money as fairly and efficiently as possible, thereby giving the customer the ability to make the decision on how to spend it rather than absorbing it into the budget,” Baze said. “Rincon Water continues to lead through our excellent customer service, our top-tier water and wastewater system, and our commitment to building a sustainable system for the future.”
Rincon Water provides safe and reliable potable and recycled water to a population of 32,000 people through more than 8,000 customer connections. Our potable distribution system consists of nine enclosed reservoirs with the storage capacity of 22.5 million gallons. The potable water system consists of over 117 miles of 8″ or bigger pipeline and four pump stations and has a peak production of 10 million gallons per day.
(Editor’s note: The Rincon del Diablo Municipal Water District is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)

Recognizing that a reliable water supply is critical to all economies and communities relying on the drought-stricken Colorado River Basin, more than 30 water agencies and providers have committed to take additional actions to reducing water demands and helping protect the Colorado River system.
Through a Memorandum of Understanding (MOU) that was delivered to the Bureau of Reclamation Commissioner Camille Touton, municipal and public water providers in the Upper and Lower Colorado River Basin affirmed their commitments to implement comprehensive and innovative water conservation programs, initiatives, policies, and actions within their communities, including:
Expanding water efficiency programs for indoor and outdoor water use.
Implementing programs and policies reducing and replacing non-functional, decorative grass by 30 percent while protecting urban landscapes and trees canopies.
Increasing water reuse and recycling programs where feasible.
Implementing water efficiency strategies and best practices, such as water loss controls, conservation-based rate structures, industrial and commercial conservation, land use coordination and other suitable conservation strategies within each community.
Colorado River Basin and megadrought
“As we consider the long-term aridification of the Colorado River Basin, the math is simple: water uses exceed water supplies,” said John Entsminger, General Manager of the Southern Nevada Water Authority. “But solving that equation will require all Colorado River water users across every sector to make hard decisions and be fully invested in water conservation if we are going to bring our shared river system into balance.
“This problem is of the highest magnitude, but collectively we have the resources to find the solution,” said Brenda Burman, Executive Strategy Advisor of Central Arizona Project. “The path forward will require all Colorado River water users to contribute, and Central Arizona Project continues to make investments and commitments to support the Basin to reach a sustainable water future.”
“The significance of nearly 30 municipal and industrial providers of Colorado River water signing on to this agreement is truly historic,” said Gene Shawcroft, General Manager of the Central Utah Water Conservancy District. “The commitments of municipal and industrial water agencies in both the Upper and Lower Colorado River Basins toward a unified approach to problem solving is critical in light of the current drought conditions and historic low reservoir elevations confronting the basin. I hope this agreement will provide an example of effective Basin-wide collaboration on the many Colorado River issues we face now and into the future.”
“Forging a sustainable future for the Colorado River will take a commitment from all of us to use less water. More than two dozen water agencies from cities across the Southwest have made this commitment on behalf of the millions of people they serve,” said Adel Hagekhalil, General Manager of the Metropolitan Water District of Southern California. “This MOU is a key step towards bringing the River into balance, and powerful proof that working together, we can build solutions.”
Metropolitan is among 30+ water agencies committing to reducing demands on the #CoRiver by implementing comprehensive and innovative water conservation programs, initiatives, policies, and actions within their communities. Read more about the MOU: https://t.co/17K3FkgPtWpic.twitter.com/2xy0HCYYUi
Under the MOU, each participating water provider will implement the conservation actions, programs and/or policies most appropriate for its individual communities and water efficiency goals. While these water agencies primarily represent urban water uses, which is only a small fraction of the Colorado River’s total water consumption, the conservation strategies outlined will help reduce demands and protect water levels in lakes Powell and Mead.
“A sustainable, long-term plan for the Colorado River Basin requires all water users to reduce water demand commensurate with what the Colorado River can realistically supply given the new normal of hotter, drier weather,” said Ron Burke, President and CEO of the Alliance for Water Efficiency. “To this end, the Alliance for Water Efficiency commends the commitments from local water providers to expand water efficiency and conservation programs.”
In a joint letter of support, seven environmental, conservation, and non-governmental organizations called the MOU “an important step in the right direction,” further stating that “achieving these commitments is a necessary first phase to preserve the longevity of the Basin.”
Today’s announcement builds upon an initial MOU executed in August 2022 between Aurora Water, Denver Water, The Metropolitan Water District of Southern California, Pueblo Water and Southern Nevada Water Authority, significantly expanding participation and commitments from water providers across the Basin to implement best practices to conserve and enhance water efficiency.
