WINGOC: Wastewater to clean water - Windhoek, Namibia

In this city, which suffers from chronic water shortage, Veolia and its partners have managed a wastewater plant since 2002. The facility recycles large volumes of wastewater in order to produce drinking water for nearly 300,000 inhabitants. Windhoek is one of the only cities in the world to recycle its water for domestic use, and the only one to do so on this scale.

The WINGOC (Windhoek Goreangab Operating Company) contract is a 20-year O&M contract signed in 2001 with the municipality of Windhoek, Namibia’s capital. The project company’s two partners are Veolia (67%) and Wabag (33%). Veolia is the majority holding company.

The project consists of a clean water treatment plant constructed in 2003. Clean water is produced from wastewater originating from the Goreangab Dam and the Gammam Reservoir, and is distributed to the city of Windhoek. The treatment process is very complex with a series of filtration (including a number of membrane stages) and ozonation stages.

This is a global benchmark, as around the world clean water is only produced from waste water in Windhoek and Singapore. In particular, reaching clean water standards is difficult in view of the level of pollution that enters.

#3 Clean water is produced from wastewater originating from the Goreangab Dam and the Gammam Reservoir...

Dang, I didn't know that the water from there were so polluted, maybe if they would just connect their sewer pipes to the waste water treatment plant instead of dumping them into their lake and rivers...
