Israel: One of the leading producers of recycled water

Almost 90 percent of Israeli wastewater is purified and used in irrigation, making it an undisputed world leader in this field, Haaretz reported on Sunday, citing a new report by the country’s Water Authority. Spain, the second-place country, recycles 20 percent of its wastewater, compared to Israel’s 87 percent. Israel is also a pioneer in desalination, operating Sorek — the world’s largest seawater desalination plant — some 10 miles south of Tel Aviv. While desalinization can be energy intensive and expensive enterprise, the advanced technologies employed at Sorek allow it to produce a thousand liters of drinking water — about what one person in Israel uses in a single week — for 58 U.S. c

Recycling sewage into drinking water: a unique tale of Namibia

The Goreangab water treatment plant uses a process that partially mimics nature to turn sewage from Winhoek's 300,000 residents back into potable water. It opened in 1968 and was the first such plant in the world. Cities around the world are wrestling with whether they should build facilities like this. But here, in the middle of a desert in a remote corner of southern Africa, they’ve been recycling wastewater for almost 50 years. It’s cutting-edge technology, but it’s based on the humblest of creatures — bacteria. The recycling process begins with a conventional sewage treatment system. But at the point where processed sewage would normally be discharged into a waterway, the Goreangab plant

Californians to drink recycled water?

Californians could soon start drinking purified wastewater. In response to a five-year drought, the state Water Resources Control Board recently informed legislators that regulating recycled, drinkable water is perfectly feasible. California would be the first state in the nation to implement such regulations. Exploring water reuse is a smart move. Policymakers have long looked to science to address water shortages — and farmers and ranchers have long recognized the value of recycled water. As California struggles to solve its water scarcity crisis, funneling purified, recycled water to the drinkable water supply is a logical step. With the right technology, the process should be sustainable
