Windhoek has turned reclaimed sewage into drinking water since 1968. The New Goreangab plant (2002) now supplies 21,000 m³/day — a quarter of the capital's water — with a second facility planned to reach 50% amid prolonged drought.

Description

Windhoek pioneered direct potable reuse (DPR) — purifying sewage effluent into drinking water without an environmental buffer — in 1968, when the original Goreangab Water Reclamation Plant became the world's first facility of its kind. It supplied the capital until 2001 and was then repurposed to produce irrigation water.
The New Goreangab Water Reclamation Plant, commissioned in September 2002, uses a multi-barrier treatment train to produce roughly 21,000 m³ of drinking water per day, meeting about a quarter of Windhoek's water demand. Namibia's capital sits in one of the driest countries south of the Sahara and has faced more than seven years of persistent drought, making reclaimed water a structural part of the city's supply rather than an emergency measure.
A second direct-potable-reuse facility (DPR2) is now planned with financing of more than US$43 million from Germany's KfW development bank, intended to lift reclaimed water's share of the capital's total consumption to about 50%. Windhoek's decades-long safety record has made it a reference case cited by utilities elsewhere, including in the United States, exploring their own direct-reuse programmes.
