00:00Would you drink recycled wastewater? In Windhoek, Namibia, people have been doing just that for
00:05decades. The city only sees rain on about 55 days a year, so every drop matters. In 1968,
00:11Windhoek became the first city in the world to turn treated wastewater directly into drinking
00:16water. Today, the plant provides 21 million liters a day. That's more than a third of the city's
00:21drinking water demand. The water goes through multiple stages of filtration, purification
00:25and test things before it's safe to drink. And Windhoek has another trick. It stores water
00:29underground, where far less is lost to evaporation. For one of the world's driest cities, reusing
00:34water is a way to survive and thrive.
