Ashkelon Desalination Plant

An award-winning, milestone plant for the desalination industry

Among the Largest SWRO Desalination Plants Worldwide

When completed, The Ashkelon reverse osmosis desalination plant was by far the world’s largest and most advanced desalination plant. With a huge capacity of up to 330,000 m3/day and with extremely high efficiency levels, the Ashkelon desalination plant achieved one of the world’s lowest ever prices for desalinated water. In 2010, due to the unmatched success of the plant, it was expanded by nearly 20% to 392,000 m3/day, providing clean water for more than a million people.
