San Diego County’s fragile shoreline and vulnerable beachfront properties could be in for a rough winter, according to the California Coastal Commission, the National Weather Service and some top San Diego scientists.
“We are looking at an emerging El Niño event,” staff geologist Joseph Street told the Coastal Commission at its meeting Wednesday in Eureka.
Legislation signed into law by California Governor Gavin Newsom ensures the state has the science and weather forecasting tools it needs for more flexible reservoir operations. The bill, AB 30, makes breakthrough water management technology standard for the California Department of Water Resources.
The legislation was introduced by San Diego Assemblymember Chris Ward and co-sponsored by the Sonoma County Water Agency and the San Diego County Water Authority. The bill was supported by the Water Authority’s partner, UC San Diego’s Scripps Institution of Oceanography.
The strategy is called forecast-informed reservoir operations, or FIRO, and it complements Gov. Newsom’s California Water Supply strategy released in August 2022 calling for more reservoir storage capacity to capture runoff from big storms, often fueled by atmospheric rivers. The governor and Legislature have already provided funding for state water managers to integrate the strategy.
“We thank Assemblymember Chris Ward for his leadership and vision in supporting next-gen water management and flood reduction efforts that will benefit residents statewide,” said Mel Katz, chair of the San Diego County Water Authority Board of Directors. “The legislation provides an innovative approach to help San Diego County and California thrive in the changing climate.”
Forecast-informed reservoir operations use weather predictions to advise dam operators about how much water to retain or release from reservoirs, enhancing their ability to handle whatever nature serves up while retaining as much water as possible in storage.
Many reservoirs in the West are strictly regulated based on historical averages of winter storms and spring runoff. Under existing rules, the highly variable rainfall from year to year is not directly considered. Complicating the problem, many current guidelines and practices were developed before satellites, radar and advanced numerical models significantly improved weather forecasts.
To address these challenges, researchers at Scripps Institution of Oceanography and elsewhere developed tools that provide weather forecasters with reliable notice of atmospheric rivers a week in advance. Advancing this research could have taken decades, but sophisticated prediction products have evolved in less than 10 years with funding by the San Diego County Water Authority and other water agencies statewide, along with state and federal support.
The Water Authority has partnered with SIO and the Scripps Center for Western Weather and Water Extremes at UC San Diego, to share and support best practices in FIRO, to increase research around atmospheric rivers and droughts, and develop strategies for mitigating flood risk and increasing water supply reliability
Water recycling reduces the need to import or develop additional drinking water supplies. It is a vital water management strategy to ensure a safe, reliable, and locally controlled water supply to support healthy environments, robust economies, and high quality of life.
Water and wastewater agencies in San Diego County are developing or expanding their water recycling infrastructure. Among those at the forefront is the Olivenhain Municipal Water District. OMWD marks a significant milestone in August: the 20th anniversary of its award-winning 4S Ranch Water Reclamation Facility, which began serving high-quality recycled water for irrigation in August 2003.
The Chino Basin Program (CBP), a program led by the Inland Empire Utilities Agency (IEUA) and partners, has reached a significant milestone as environmental engineering firm Brown and Caldwell completes the preliminary design of a new 13.4 million gallons per day Advanced Water Purification Facility (AWPF), a vital component of the innovative water program.

OMWD annexed the 4S Ranch and Rancho Cielo Sanitation Districts from the County of San Diego in 1998. OMWD also took ownership of a small wastewater treatment facility in 4S Ranch. This facility had the capability to treat 0.25 million gallons per day (MGD) of wastewater from the surrounding commercial center and condominium complex. Treated wastewater was disposed of by spraying it on nearby unimproved pastures.
Recognizing the significant development plans for the 4S Ranch area, OMWD expanded the capacity of the facility to 2.0 MGD. As part of this expansion, OMWD also incorporated additional treatment phases of filtration and ultraviolet disinfection, improving water quality. OMWD required area developers to install the entire recycled water infrastructure for their planned communities.
Today, the facility produces over one million gallons of recycled water per day. It is delivered to irrigation customers in the southeastern portion of OMWD’s service area for use at HOA common areas, schools, parks, streetscapes, and golf courses. Together with recycled water purchased from nearby water and wastewater agencies to serve customers in portions of Encinitas and Carlsbad, OMWD now serves up to 15 percent of its customers’ total water demand with recycled water.
“For 20 years, OMWD has proudly served 4S Ranch and neighboring communities with high-quality recycled water, reducing the use of drinking water for irrigation,” said OMWD Vice President Matthew Hahn. “As California continues to face water supply challenges, the expansion of our recycled water system strengthens our water supply reliability and promotes sustainable water management.

Water recycling is the process of capturing and treating wastewater, for non-domestic purposes such as irrigation and industrial processes.
Water and wastewater agencies across San Diego County are developing or expanding their recycled water systems to reduce the need to import or develop other supplies.
Since 2003, OMWD has significantly increased its recycled water purchases through connections with neighboring agencies, including the City of San Diego, San Elijo Joint Powers Authority, Rancho Santa Fe Community Services District, and Vallecitos Water District. OMWD now serves over two and a half million gallons of recycled water every day. Each year, OMWD installs additional recycled water pipelines and converts more customers from potable water to recycled water.
By 2027, the volume of recycled water produced in the U.S. is projected to increase 37% from 4.8 billion gallons per day to 6.6 billion gallons per day, according to a recent survey by Bluefield Research.

As a founding member of the North San Diego Water Reuse Coalition, OMWD works with nine northern San Diego County water and wastewater agencies across jurisdictional boundaries to reduce the impact of water supply shortages on San Diego County’s $268 billion economy. This regional approach has proven successful in developing local projects as well as obtaining $9 million in funding, significantly reducing the costs of water recycling projects for North San Diego County water ratepayers.
In addition, the Coalition has also secured federal funding of $23.8 million to help cover costs for water reclamation projects through 2025.

As it looks forward to the next 20 years, OMWD continues to expand its recycled water capacity. It began construction this summer on three recycled water pipelines near Calle Barcelona in Carlsbad and in Village Park in Encinitas. Once complete, OMWD can convert up to 27 meters to recycled water, offsetting 12.7 million gallons of potable water used annually for irrigation.
OMWD has long pursued alternative water supplies like recycled water, a reliable, drought-proof approach for complementing existing water sources.
The San Diego County Water Authority has supported the development of recycling projects for decades, through membership in groups such as the WateReuse Association and collaborative efforts to promote local reuse efforts. Approximately 35,000 acre-feet of recycled water is beneficially reused within the Water Authority’s service area annually, and the volume is expected to continue growing as new and expanded plants come online.

Encinitas, Calif. — Olivenhain Municipal Water District continues to expand its recycled water distribution by connecting to the Rancho Paseana horse ranch, providing the property with locally produced, tertiary treated recycled water for irrigation.
The Rancho Paseana horse ranch is located in Rancho Santa Fe and covers approximately 225 acres. Connecting this property to OMWD’s recycled water system is estimated to save as much as 163 million gallons of imported drinking water every year. The property will now use recycled water for irrigation of its equestrian facilities.
“Given the regulatory and climatic challenges that are impacting water supply reliability for all of California, it’s imperative that we continue to explore local supply alternatives that are resilient to drought,” said OMWD Board Secretary Larry Watt. “Every new customer we convert to recycled water decreases our demand for imported drinking water and therefore creates a more reliable system for our customers.”
OMWD produces up to two million gallons of recycled water daily at its 4S Ranch Water Reclamation Facility, and supplements this supply with recycled water purchased from neighboring water and wastewater agencies. By partnering with other agencies and sharing resources across jurisdictional boundaries, OMWD is able to continue expanding its recycled water distribution system. In total, OMWD meets up to 15 percent of its demands with recycled water.

The Vista Irrigation District, one of the San Diego County Water Authority’s 24 member agencies, is celebrating its 100th anniversary.
In the 1920s, citrus and avocado farming in the Vista area increased so quickly that the growing region faced the real danger of running out of water. Completing the Henshaw Dam in 1923 made it possible for the Vista community to receive a reliable water source instead of relying on well water.
The arrival of the new water source sparked discussion about forming a water district to secure additional imported water to make continued growth possible. On August 28, 1923, voters approved the formation of the Vista Irrigation District (VID) in a landslide: 104 votes to four votes in a 100% voter turnout.
A state water board will consider a proposed cease-and-desist order for the egg processing facility at Pine Hill Egg Ranch in Ramona over concerns that contaminated water has been getting into stormwater basins and two nearby creeks, officials said.
The California State Water Resources Control Board will discuss the order at its Oct. 11 meeting. Public comment on the issue through Aug. 28 will be taken into consideration by the board, officials said.

In its first year, VID served 337 customers. Today, VID serves water to more than 134,000 customers in a diversified community and robust economy and is celebrating its 100th anniversary on August 28, 2023.
“Vista Irrigation District is proud of its accomplishments over the last century and looks forward to providing reliable water service to the residents and businesses it serves for years to come,” said Board President Jo MacKenzie.
The Vista community celebrated the arrival of the first water from Lake Henshaw on February 27, 1926. Following the arrival of water, crops of all kinds were planted in increasing numbers. The Vista area became known as the “Avocado Capital of the World,” with six avocado packing houses in the area.
In June 1946, after several years of negotiations, Vista Irrigation District purchased the San Diego County Water Company. Included in the purchase was the 43,000-acre Warner Ranch, a former Spanish Land Grant, which includes Henshaw Dam and Lake Henshaw. The deal was driven by the economic motivation to find another, less costly source of water for VID’s customers.

Drought conditions and population growth continued to press VID to seek additional sources of water. On February 16, 1954, the Vista Irrigation District became a member of the San Diego County Water Authority. It allowed VID to bring in water imported from the Colorado River and Northern California.
One year later, in 1955, Vista’s first suburban-style housing arrived in what had been an agricultural community. The Vista area began experiencing a decline in its avocado producing and packing due primarily to the industry’s economic decline and drought, which would continue into the 1960s. Many avocado groves were split into smaller parcels and sold to housing developers. The land was more valuable for homes.

The people’s vote in 1923 revolutionized the small rural settlement held back by a lack of water. Over the years, Vista transformed itself from its agricultural origins to a thriving community with a diversified economic base and a revitalized downtown.
Today, Vista is a thriving community that continues to grow and develop many new activities and attractions, such as its popular Moonlight Amphitheatre. Photo: City of Vista
Vista Irrigation District has demonstrated its ability to adapt to these ever-changing landscapes over time and looks forward to many more successful years of service to the community. Through a century of service and stewardship, the Vista Irrigation District can take credit for its solid track record over the last century to continue many more successful years of service to the community.
(Editor’s note: The Vista Irrigation District is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region. The District is celebrating “A Century of Service and Stewardship” on Saturday, September 9, at its Vista headquarters. The public is invited to attend.)
