Carlsbad Desalination Plant Celebrates 5th Anniversary
The Claude “Bud” Lewis Carlsbad Desalination Plant is celebrating its fifth year of operation this month. More than 65 billion gallons of water from the plant have provided a sustainable and reliable supply to businesses and residents of San Diego County since December 2015.
The Carlsbad Desalination Plant produces more than 50 million gallons of high-quality, locally controlled, water every day. It’s a foundational water supply for the San Diego region that minimizes the region’s vulnerability to drought or other water supply emergencies.
Opinion: Poseidon Would Bring Jobs and Water to Orange County
We’ve seen this story before: What do you do when someone doesn’t have science on their side? You make up a conspiracy story. And better yet, you try to piggyback on a politically charged conspiracy theory with no ties to reality.
And that’s exactly what Gary Brown attempts to do in his opinion piece regarding the Poseidon project, “Governor’s talk on environment falls short when it comes to the Poseidon project,” Dec. 3.
He claims that desalination is somehow tied to a bigger conspiracy involving Gov. Gavin Newsom and shady backroom politics. Well, hang on to your tinfoil hat. There’s no government conspiracy here — it’s actual science.
Carlsbad Desalination Plant Celebrates 5th Anniversary
The Claude “Bud” Lewis Carlsbad Desalination Plant is celebrating its fifth year of operation this month. More than 65 billion gallons of water from the plant have provided a sustainable and reliable supply to businesses and residents of San Diego County since December 2015.
The Carlsbad Desalination Plant produces more than 50 million gallons of high-quality, locally controlled, water every day. It’s a foundational water supply for the San Diego region that minimizes the region’s vulnerability to drought or other water supply emergencies.
Desalination plant diversifies region’s water supply sources
“The desalination plant is a key piece of the region’s multi-decade strategy to diversify our water supply portfolio,” said Sandra L. Kerl, general manager of the San Diego County Water Authority. “As we celebrate five years of operation, the plant continues to provide a drought-proof supply that reduces our dependence on imported water sources vulnerable to droughts, natural disasters, and regulatory restrictions.”
A 30-year Water Purchase Agreement between Poseidon Water and the Water Authority allows for the production of up to 56,000 acre-feet of water per year, enough to meet the needs of approximately 400,000 people. The facility is the largest, most technologically advanced and energy-efficient desalination plant in the nation.
Carlsbad Desalination Plant celebrates water supply accomplishment
“The Carlsbad Desalination Plant was once merely an ambitious vision. Fast forward to today, and we are celebrating the plant’s fifth anniversary of operations, during which we have successfully produced enough water to meet the needs of San Diego County residents,” said Carlos Riva, CEO of Poseidon Water. “This is an incredible accomplishment and an example of how communities throughout California can invest in the state’s future water security.”

Desalination uses reverse osmosis technology to remove water molecules from seawater. Water from the ocean is forced through tightly-wrapped, semipermeable membranes under very high pressure. The membranes allow the smaller water molecules to pass through, leaving salt and other impurities to be discharged from the facility.
Reverse osmosis is the heart of the Carlsbad plant. During this process, dissolved salt and other minerals are separated from the water, making it fit for consumption. This reverse osmosis building contains more than 2,000 pressure vessels housing more than 16,000 reverse osmosis membranes. Photo: San Diego County Water Authority
Milestones
July 22, 2020: New Seawater Intake Pumps Preserve Marine Environment
Three new fish-friendly seawater intake pumps, commissioned in July 2020 at the Claude “Bud” Lewis Carlsbad Desalination Plant, are among the most environmentally advanced intake pumps in the world. The pumps are part of a broader effort to ensure the long-term health of the marine environment near the Plant, which sits on the shores of Agua Hedionda Lagoon.

Installation of the new intake pumps is part of a phased program to replace the existing seawater intake and discharge facilities with state-of-the-art technology to protect marine life. The technology wasn’t available when the plant was operating with source water from the Encina Power Station.
The next steps include adding new intake screens, designed to prevent any sea-life larger than 1 millimeter (thicker than a credit card) from entering the plant. The new intake screens are the final part of upgrades, which when complete in 2023, will make the Carlsbad Desalination Plant the first desalination facility in California to comply with the 2015 California Ocean Plan Amendment, among the most advanced sea-life protection measures.
December 13, 2018: Carlsbad Desalination Plant Celebrates 40 Billion Gallons Served
Desalination plant project partners Poseidon Water and the San Diego County Water Authority celebrated delivering 40 billion gallons of drought-resilient drinking water to San Diego County during three years of commercial operations at the plant.
“It’s incredible what we’ve accomplished in three years,” said Sandra L. Kerl, at the 2018 celebration event, general manager of the Water Authority. “Since coming online in 2015, the Carlsbad Desalination Plant has met nearly 10 percent of the region’s water demand, and it will be a core water resource for decades to come.”

Delta Dilemma: Fishing or Fresh Water
The quiet of morning broke as a battery of boats roared toward first light on the open water.
Dozens of anglers, competing in teams of two for the biggest bass they could find, disappeared beyond the weed beds and tule thickets into the maze of rivers and sloughs. Each was chasing a cash prize and the satisfaction of conquering one of the West’s premier spots for sportfishing: the Sacramento-San Joaquin River Delta.
