Turning wastewater into drinking water
In many regions of the world, access to clean drinking water is not a matter of course. A functional supply is frequently only possible through the use of all available resources. Therefore, in some arid and semi-arid areas, the utilisation of wastewater as an additional water source represents a viable solution to existing shortages.
Naturally, there must be absolute certainty that the utilisation and consumption of this water do not involve any risks to humans. WABAG has the know-how and the technologies required to provide drinking water from municipal wastewater.
WABAG combines various process steps in sophisticated multi-barrier systems, in order to allow the production of high-quality drinking water from the outflow of municipal wastewater treatment plants.
Flocculation, sedimentation, oxidation, filtration, activated carbon filtration, membrane processes and disinfection are the most important technologies, used and combined in this connection.
With the realisation of a unique drinking water plant in Windhoek, Namibia, WABAG has demonstrated the feasibility of wastewater reuse up to the return of water to the drinking water network. Since start-up in 2001, the plant has been producing 21,000 m3 of clean drinking water per day.
