The Huntington Beach plant would be the biggest in the western hemisphere and would produce 189 million litres (50 million gallons) of drinking water a year. The downside is that in for every 2 litres of water that go in, only 1 will come out, and the leftover super-salty brine would mix in with the city's wastewater before being piped back out to sea to spread around, about 50 km offshore. And this salty brine, along with financial concerns, have environmentalists questioning the governor’s plan.
"The biggest concern about desalination is that it is expensive, it's energy-intensive and it has a lot of side effects - a lot of unintended consequences to marine life both from the intake and the discharge," Marco Gonzalez, the executive director of the US Coastal Environmental Rights Foundation, told NPR News.
