The Red Sea–Dead Sea Conveyance (RSDSC), sometimes called the Two Seas Canal, was a planned pipeline to run from the coastal city of Aqaba by the Red Sea to the Lisan area in the Dead Sea. Its abandonment was reported in June 2021.
It was to provide potable water to Jordan, Israel and the Palestinian territories, bringing water with a high concentration of salts resulting from the desalination process (reject brine) to stabilise the Dead Sea water level, and generate electricity to support the energy needs of the project. The project was planned to be carried out by Jordan and is entirely in Jordanian territory. It was to be financed by the governments of Jordan, Israel, and a number of international donors.
The water level in the Dead Sea is shrinking at a rate of more than one metre per year, and its surface area has shrunk by about 33% since the 1960s. This is largely due to the diversion of most of the flow into the Dead Sea from the Jordan River, much of which originates in the Sea of Galilee. The completion of the National Water Carrier scheme in 1964 diverted water for Israel, Jordan and Syria to use for irrigation and drinking water.
The decline of the Dead Sea level is causing major local environmental problems, including sinkholes and receding shorelines. Other routes for a conduit for the same objectives as the RSDSC, including the Mediterranean–Dead Sea Canal, were proposed in Israel in the 1980s, but were discarded. The project had a tentative $10 billion price tag, with the first phase—slated to begin construction in 2021—costing $1.1 billion.
