Where is the world's largest desalination plant? It's in Sorek, Israel, near Tel Aviv. According to a CNBC article, "The Sorek desalination plant is producing 624,000 cubic meters (of water) per day, which is about 20 percent of the domestic usage in Israel," said Miriam Faigon, senior director of water solutions and products at IDE Technologies. IDE Technologies specializes in water treatment.
Remember, desalination is the process of turning seawater into drinking water. In areas of the world that deal with water scarcity, desalination plants make sense. In fact, according to the same CNBC article, "IDA states that over 300 million people worldwide depend on desalinated water for 'some or all their daily needs'". IDA is the International Desalination Association.
