JERUSALEM -- The Dead Sea has been rapidly disappearing for the past 50 years, one of the world's natural wonders careening toward ecological collapse.
But in a deal signed Monday and hailed as "historic," Israel, Jordan and the Palestinian Authority agreed on an ambitious project to begin to refill the ancient salt lake with briny water pumped from the Red Sea.
The agreement calls for construction of a large desalination plant in Jordan, on the Gulf of Aqaba, that would suck billions of gallons from the Red Sea and convert it to drinking water. The water would be shared by -- and sold to thirsty customers in -- Jordan and Israel. In addition, as part of the agreement, Israel agreed to increase the amount of water it sells annually to the Palestinian Authority by as much as 30 million cubic meters.
Billions of gallons of "reject brine" -- essentially, super-salty water created by the desalination process -- would be pumped via a new, 100-mile pipeline and discharged into the Dead Sea.
Estimated construction costs for the pipeline and desalination plant could run about $500 million. The first drop of water to enter the Dead Sea would probably not appear before 2017.
"This is a historic agreement that realizes a dream of many years," said Silvan Shalom, the Israeli water and energy minister. "The agreement is of the highest diplomatic, economic, environmental and strategic importance."
And hopefully not too late. The deal was signed Monday in a ceremony at the World Bank in Washington, which for years has underwritten feasibility studies, environmental assessments and economic modeling about how not only to save the Dead Sea, but also how to share costs and resources to provide drinking water for a thirsty region bristling with conflict.
The project, supported by the Obama administration as a symbol of regional cooperation and a sign for what could be accomplished if peace were to take hold, has been the subject of study and debate since the 18th century.
