Why Israel Shocked the World to Save a Biblical Lake

A lake sits 700 feet below sea level—the lowest freshwater lake on Earth. For sixty years, Israel's National Water Carrier drained it to keep a growing nation alive. Today, that exact pipeline runs backward, pumping millions of gallons of desalinated ocean water uphill across the country to save it. In this documentary, we break down the massive engineering and physics behind Israel's Flow Reversal Project. Discover how massive coastal reverse-osmosis plants like Sorek and Sorek II use energy recovery units to slash the cost of fresh water, how hydraulic engineers solved lethal water hammer shockwaves to push seawater across mountain ridges, and how keeping the Sea of Galilee alive quietly underpins geopolitics, regional peace treaties, and the future of global water crises like Lake Mead.
