When it comes to the view of desalination as a tool to drought-proof local water systems in California, 2022 has been a roller-coaster year. In May, the California Coastal Commission, a 12-member appointed board responsible for overseeing the state’s 1,100 miles of coastline, rejected on environmental grounds a $1.4 billion desalination facility proposed for Huntington Beach.
Paloma Aguirre has fought to clean up the sewage-plagued waters of Imperial Beach for the better part of the last two decades — first as an activist and most recently as the city’s first elected woman of Mexican descent. The city’s newly minted mayor says her highest priority next year will be working with officials in Baja California to stem the pollution that routinely spills over the border and floats up the coastline.
The first of two Pacific storms will push into San Diego County on Tuesday night and likely drop a half-inch or more of rain at and near the coast and slightly more in the foothills and mountains by early Wednesday, says the National Weather Service. The rain represents the tail of a much larger system that is soaking the Bay Area and is expected to bring heavy snow to the Sierra Nevada, benefiting many of the state’s reservoirs.
San Diego’s southernmost beaches are blighted by sewage that spills into the cross-border Tijuana River and flows to the ocean. Before 2022, the best available coastal water testing technology took so long to furnish results that public health officials couldn’t surmise how safe the water was until days after visitors swam in it.
The city of San Diego and East County leaders have resolved a months-long dispute over a planned water recycling project, heading off a potentially expensive court fight over what to do with the plant’s waste.
The Water News Network top stories of 2022 were drought-related and features about technology and college scholarships also engaged readers.
The #1 Water News Network Top Story of 2022 focused on scholarship opportunities for water industry education and the growing need for water and wastewater industry workers:
Multiple California water associations and water agencies in San Diego County are offering college scholarships to help candidates achieve their goals.
A large number of recent retirements combined with the need for a skilled workforce up to date on new technologies have resulted in a critical need to increase the talent pool of skilled individuals in the water and wastewater industry, including in San Diego County.

Among the highlights in the January 20 story, was news about the Mark Watton Scholarship Fund, established by the Otay Water District at the Foundation for Grossmont and Cuyamaca Colleges. The fund supports students attending the Center for Water Studies at Cuyamaca College. It honors Otay Water District General Manager Mark Watton’s four decades of service to the district.
The #2 most viewed story on the Water News Network in 2022 highlighted an innovative tool to inspect pipelines developed by the San Diego County Water Authority:
The Water Authority has been granted its first ever utility patent for a device that inspects interior sections of water pipelines that are inaccessible or not safe to inspect without expensive specialized gear and training.
Water Authority Operations and Maintenance Manager Martin Coghill invented the tool to save time, reduce costs and improve safety during ongoing aqueduct inspections. The Water Authority’s industry-leading Asset Management Program includes a proactive search for pipeline weaknesses that can be addressed before they become large and costly problems.
The U.S. Patent and Trademark Office awarded Patent #US011,293,581 on April 5, 2022, for the Water Authority’s pipeline inspection system, which comprises a body, cameras, support members and light sources to capture high-resolution images of pipeline walls.

“This new pipeline inspection tool is a prime example of the Water Authority’s commitment to innovation that benefits ratepayers by saving money and enhancing reliability,” said Water Authority General Manager Sandra L. Kerl. “We have a long history of advancing industry-leading solutions, from state legislation to adopt low-flow toilets in the early 1990s to the nation’s largest water conservation-and-transfer program a decade later to the largest seawater desalination plant on the continent.”
The third most-viewed story detailed the California state tax breaks available and rebates to remove grass and save money, as California edged into the fourth consecutive year of drought:
A newly signed state law exempts local rebates for grass replacement from state income tax, ensuring more dollars can be spent creating beautiful and functional WaterSmart yards.
“Drought conditions make it imperative to boost water conservation in San Diego County and across the state,” said Sandra L. Kerl, general manager of the San Diego County Water Authority. “Using California tax incentives and regional rebates to install WaterSmart landscapes is a clear winner for stretching water supplies both today and for generations to come.”

The WNN feature story alerted homeowners and businesses in San Diego County that they are eligible to receive between $2 and $4 per square foot for removing grass and replacing it with low water-use plants that are better suited to withstand the hot and dry conditions that continue to hammer the West. All customers are eligible for the base rebate of $2 per square foot, but other agencies offer additional funding, including the City of San Diego and the County of San Diego.

Coming in as the 4th most popular story on the WNN in 2022 was the benefit of seawater desalination providing a drought-proof supply for San Diego County:
As the worst drought in 1,200 years grips the West, the Claude “Bud” Lewis Carlsbad Desalination Plant is protecting the San Diego region with 50 million gallons a day of drought-proof water.
Completed in 2015, the plant was built before the period of increasing inflation that’s driving up prices for water infrastructure projects that are just starting. That means the desal plant is safeguarding the region’s economy and quality of life today at a lower cost than it would be to build now.
The Carlsbad Desalination Plant uses reverse osmosis to produce approximately 10% of the region’s water supply; it is a core supply regardless of weather conditions, and it is blended with water from other sources for regional distribution. Photo: San Diego County Water Authority
“Desalination remains a valuable tool for our community when it comes to ensuring safe and reliable water supplies no matter the weather,” said Jeremy Crutchfield, water resources manager for the Water Authority. “It has shown its value by generating nearly 90 billion gallons over the past six years, and I’m confident it will continue to do so in the years ahead.”
In late-October 2022, the Carlsbad Desalination Plant passed a milestone, having served more than 100 billion gallons of high-quality, locally controlled water over the past seven years – as California entered a fourth consecutive year of severe drought.

Scientists have discovered that the pace of groundwater depletion in California’s Central Valley has accelerated dramatically during the drought as heavy agricultural pumping has drawn down aquifer levels to new lows and now threatens to devastate the underground water reserves. The research shows that chronic declines in groundwater levels, which have plagued the Central Valley for decades, have worsened significantly in recent years, with particularly rapid declines occurring since 2019.
On a crisp day this fall I drove southeast from Grand Junction, Colorado, into the Uncompahgre Valley, a rich basin of row crops and hayfields. A snow line hung like a bowl cut around the upper cliffs of the Grand Mesa, while in the valley some farmers were taking their last deliveries of water, sowing winter wheat and onions. I turned south at the farm town of Delta onto Route 348, a shoulder-less two-lane road lined with irrigation ditches and dent corn still hanging crisp on their browned stalks. The road crossed the Uncompahgre River, and it was thin, nearly dry.
With climate change and drought, the state of California is incentivizing not using farmland or fallowing it. The move comes as irrigation in some areas is damaging residential wells. Katie Staack farms 3,500 acres of almonds in Stanislaus County. She is one of the hundreds interested in the newly created LandFlex program. “The program is really unique because it’s focused on wet water, making sure we have wet water for our communities and aquifers, our ecosystems and farms,” Aubrey Bettencourt said.
The outskirts of Kingman, Arizona, used to be a place where pilots would train and recreationists tested their all-terrain vehicles. The dry and empty landscape has since morphed into something much more green that supports pistachio and almond orchards, and garlic and potato fields in a climate similar to California’s Central Valley. The crops are fed by groundwater that also serves the city of Kingman.
