Claude "Bud" Lewis Carlsbad Desalination Plant New. Reliable. Drought-Proof.
Claude “Bud” Lewis Carlsbad Desalination Plant
The San Diego County Water Authority and Poseidon Water on Dec. 14, 2016, marked the first anniversary of operations at the Claude "Bud" Lewis Carlsbad Desalination Plant. It was a historic first year, with the plant garnering local and international accolades while generating locally controlled, drought-resilient supplies that helped reduce state water-use mandates. Desalinated seawater then helped San Diego County pass the state's water supply "stress test" in June, ending the state’s emergency water-use mandates in the region.
The plant produces approximately 50 million gallons per day of locally controlled water for San Diego County, helping to minimize the region’s vulnerability to statewide drought conditions. It is part of a $1 billion project that includes the nation’s largest and most technologically advanced and energy-efficient seawater desalination plant, a 10-mile large-diameter pipeline and improvements to Water Authority facilities for distributing desalinated seawater throughout San Diego County. The plant meets approximately 10 percent of the region’s water demand – about one third of all the water generated in the county.
Development of the nation's largest seawater desalination project followed years of planning and consideration.Learn More
