Last November, the California Coastal Commission approved a permit for a sprawling, $330 million seawater desalination facility in Marina—a blue-collar city of 22,500 residents that is located about 15 minutes north of the more affluent community of Monterey. If approved, Cal-Am’s desalination plant would produce 4.8 million gallons of freshwater per day and would be the first seawater desalination plant constructed in California in nearly a decade.

The wave energy desalination plan is just one on a staggering list of quixotic-sounding ideas the city is exploring for creating enough water for the future, some already functioning such as the city’s desalination device, installed in just a few months last summer. In addition to creating fresh water, the proposals being considered by the city include innovations in use of solar and wave energy, desalination and environmentally friendlier reservoirs. Other ideas that have been looked at include a proposal to the state for aquaculture, large solar dehumidifiers, water brought by train, water conservation measures and buying water […]

That’s according to the latest estimate from South Coast Water District, which has spent more than $10 million and 20 years planning for a desalination plant to help stabilize supplies for residents who currently depend on pricey and frequently restricted imports from the Colorado River or the State Water Project.

For the pilot project, an Iceberg-class unit, the 9th generation of this technology which has been refined over seven years in the ocean environment, will be deployed along the Fort Bragg coast.

During the pilot project, one Iceberg-class unit is expected to produce up to 13,200 GPD (50 m3/day) over a 12-month period while emitting zero greenhouse gases and saving 1 ton of CO2e per year for each m3 of fresh water produced daily, compared to diesel-powered desalination plants.

The Carlsbad Desalination Plant is the largest in the United States, and has the capacity to produce 50 million gallons of water per day, according to its website.

In 2021, as the Clean Energy Alliance began serving residential and business customers in Del Mar, Solana Beach and Carlsbad, CEA and San Diego County Water Authority officials held discussions about the CEA serving the Channelside account, according to the CEA staff report. But the water authority elected to opt out of service from the CEA, which is an option for all customers within the agency’s member […]

Funded by Proposition 1, a $7.545 billion bond approved by voters in 2014, the Water Desalination Grant Program supports the construction and design of pilot projects that desalinate naturally occurring brackish and ocean water for drinking water supply.
