The Sorek desalination plant is bringing abundant clean water to Israel.

The Sorek desalination plant is bringing abundant clean water to Israel.


“We are standing above the new Sorek desalination plant, the largest reverse-osmosis desalination facility in the world, and we are staring at Israel’s salvation. Just a few years ago, in the depths of its worst drought in at least 900 years, Israel was running out of water. Now it has a surplus. That remarkable turnaround was accomplished through national campaigns to conserve and reuse Israel’s meager water resources, but the biggest impact came from a new wave of desalination plants.

Edo Bar-Zeev and colleagues developed a chemical-free system using porous lava stone to capture the microorganisms before they reach the membranes. It’s just one of many breakthroughs in membrane technology that have made desalination much more efficient. Israel now gets 55 percent of its domestic water from desalination, and that has helped to turn one of the world’s driest countries into the unlikeliest of water giants.

Desalination used to be an expensive energy hog, but the kind of advanced technologies being employed at Sorek have been a game changer. Water produced by desalination costs just a third of what it did in the 1990s. Sorek can produce a thousand liters of drinking water for 58 cents.

The institute’s original mission was to improve life in Israel’s bone-dry Negev Desert, but the lessons look increasingly applicable to the entire Fertile Crescent. “The Middle East is drying up,” says Osnat Gillor, a professor at the Zuckerberg Institute who studies the use of recycled wastewater on crops. “The only country that isn’t suffering acute water stress is Israel.”

Bar-Zeev believes that Israel’s solutions can help its parched neighbors, too — and in the process, bring together old enemies in common cause.”

    • Right now it’s probably powered by the grid. The article mentioned that they’re working on solar powered desal plants for the future.
