SAN DIEGO (AP) — San Diego's regional water agency has approved a contract to buy the entire output of what would be the Western Hemisphere's largest seawater desalination plant.
The San Diego County Water Authority voted on the 30-year contract Thursday. Poseidon Resources LLC needed the deal to finance construction of the $984 million project.
The plant in Carlsbad is designed to produce 50 million gallons of highly purified drinking water a day, enough to supply about 8 percent of the region in 2020.
The water would be more than twice as expensive as San Diego's imported supplies but backers said it would be well worth the premium to protect against drought.
