# Large-Scale Seawater Reverse Osmosis Desalination

Israel produces 80%+ of its drinking water from desalination, operating five mega-plants including Sorek — one of the world's largest and most efficient SWRO facilities.
- Technology Readiness Level: 9/9
- Impact: 5/5
- Investment: 4/5
Israel has built the world's most advanced large-scale seawater reverse osmosis (SWRO) desalination infrastructure, with five major coastal plants (Ashkelon, Palmachim, Hadera, Sorek, Ashdod) collectively producing over 585 million cubic meters of potable water annually — more than 80% of domestic drinking water. The Sorek plant, using advanced 16-inch RO membrane technology and energy recovery devices, achieves among the lowest desalination costs globally at approximately $0.50/m³. A sixth plant (Sorek-2) and a northern facility are under construction.

Israel's desalination program is the most successful national-scale deployment of the technology in history, transforming a water-stressed nation into one with surplus supply. The achievement is particularly remarkable because it was driven by existential necessity — Israel's natural freshwater sources could not sustain a growing population in a region where water access is geopolitically contested. IDE Technologies and other Israeli firms developed innovations in membrane cleaning, energy recovery, and intake/outfall systems that set global benchmarks.

Strategically, Israeli desalination expertise is a major export and soft-power tool. IDE has built plants in the U.S., China, India, and Australia. As climate change intensifies water scarcity worldwide — affecting 2+ billion people — Israeli desalination technology and operational know-how represent a critical capability for global adaptation. The technology also feeds Israel's agricultural water recycling system, creating a circular water economy that is studied worldwide.
