Water-starved cities around the world are starting to turn to a once-unpalatable solution: recycling their sewage. And they have a surprising pioneer to thank for developing the technology — the southern African desert country of Namibia.
New York City drew the reservoir down to an unprecedented level last winter — but only because forecasting told city official that it would soon be able to refill with an unprecedented amount of snowmelt.
India's monsoon is still nearly a month away, and the heat is scorching, but parts of the country have nearly run out of water. Meanwhile, fires burn and people struggle with a half hour of water a day — or less.
