Carlsbad, CA -- An independent water quality study was conducted between 2014 and 2016 to compare data before and after the integration of desalinated water produced at the Carlsbad. The results were overwhelmingly positive.

The integration of desalinated water improved overall water quality by decreasing total dissolved solids and chlorides and the desalinated water exhibited much lower water hardness and alkalinity.  This improved water quality and purity may help extend the life of household appliances like water heaters – saving consumers money and increasing household efficiency.

On May 8th, the San Diego Regional Water Quality Control Board approved the long-term operation of Poseidon Water’s Claude “Bud” Lewis Carlsbad Seawater Desalination Plant. The Carlsbad facility, the largest, most technologically advanced and energy efficient seawater desalination plant in the Americas, is the first facility to be approved under the State Water Resources Control Board’s seawater desalination regulations.
 
According to the San Diego Regional Water Quality Control Board’s press release, “Desalinated water, as regulated by the permit for Poseidon, is an important component of our overall water supply portfolio,” said San Diego Water Board chair Henry Abarbanel. 

​HUNTINGTON BEACH, Calif.-- Poseidon Water Vice President Scott Maloni today issued a statement in response to Governor Gavin Newsom’s executive order.
​
 “This week, California Governor Gavin Newsom delivered an executive order to develop a strategy for a climate-resilient water system. We couldn’t agree more and the implementation of seawater desalination in California is a great first step,” said Scott Maloni, vice president, Poseidon Water. “Many of California’s existing challenges, including severely depleted groundwater aquifers and uncertain water supplies, stem from the need for a new, reliable and sustainable water resource. Seawater desalination is a proven technology that is the only

Recognizing the need for a climate-resilient water portfolio like desalination, Governor Gavin Newsom issued Executive Order N-10-19, which acknowledges that climate change will increase the risk of drought and water supply reliability and directs local state agencies to prepare a plan for prioritizing climate-resilient water supplies.  Desalination is the single largest climate resilient water supply solution available in the state today.

The Huntington Beach Desalination Facility will produce 50 million gallons of drinking water per day from an untapped and drought-proof source – the Pacific Ocean.
