Almost 90% of Israeli wastewater is purified and used in irrigation, making it an undisputed world leader in this field. Israel is also a pioneer in desalination, operating Sorek — the world’s largest seawater desalination plant. The advanced technologies employed at Sorek allow it to produce a thousand litres of drinking water — about one week’s use per person — for US58c (R7.73).
