Take Action: Oppose Costly Desalination in Orange County

The proposed Poseidon desalination plant in Huntington Beach would increase the cost of water for Orange County families, harm our ocean and our climate, and we don’t need it!

Help us stop it. Please tell the Santa Ana Regional Water Quality Control Board today to say NO to Poseidon’s expensive, unnecessary, environmentally damaging project.

Orange County families, local leaders and water experts are urging you to say NO to Poseidon’s proposed desalination plant in Huntington Beach. This $1.4-billion-dollar boondoggle would be too expensive for Orange County families, too destructive to our ocean, too harmful for our climate, and we don’t need it!

Scientists and water experts agree that desalination should be our last resort in meeting our water needs.

We oppose the Poseidon project because:

Orange County has cheaper, cleaner water options. Local solutions like water recycling, conservation, and cleaning up contaminated groundwater are the best alternatives to wasteful water projects like Poseidon, at a fraction of the cost.

The Poseidon plant is a billion-and-a-half-dollar boondoggle and would increase water bills for Orange County families, hurting low-income families and coastal businesses like hotels and restaurants. 

We need to protect Orange County’s oceans and beaches. The Poseidon plant would kill ocean life, pollute our water supplies with boron and chloride, and discharge polluted brine into our coastal waters creating a “dead zone” offshore of Huntington Beach.

The water is not needed. The 2018 Municipal Water District of Orange County Water Reliability Study showed the Poseidon project is the least cost-effective and most financially risky way to meet our future water needs. Orange County has many less costly, less financially risky, and more environmentally sound alternative sources of water available.

We need to protect our climate. Desalination is the most energy-intensive way to produce fresh water and would generate more climate pollution. The Poseidon plant’s location is vulnerable to flooding from rising seas and extreme storms, as well as earthquakes and tsunamis.

We urge you to reject the proposed Poseidon desalination plant.
