"In California, What Price Water?"

"CARLSBAD, Calif. — On a calm day, a steady rain just about masks the sound of Pacific Ocean water being drawn into the intake valve from Agua Hedionda Lagoon. Listen hard, and a faint sucking sound emerges from the concrete openings, like a distant straw pulling liquid from a cup."



"At the moment, the seawater is being diverted from the ocean to cool an aging natural-gas power plant. But in three years, if all goes as planned, the saltwater pulled in at that entryway will emerge as part of the regional water supply after treatment in what the project’s developers call the newest and largest seawater desalination plant in the Western Hemisphere.

Large-scale ocean desalination, a technology that was part of President John F. Kennedy’s vision of the future half a century ago, has stubbornly remained futuristic in North America, even as sizable plants have been installed in water-poor regions like the Middle East and Singapore.

The industry’s hope is that the $1 billion Carlsbad plant, whose builders broke ground at the end of the year, will show that desalination is not an energy-sucking, environmentally damaging, expensive white elephant, as its critics contend, but a reliable, affordable technology, a basic item on the menu of water sources the country will need."
