Poor wastewater management is causing both environmental damage and health risks for the people of South Africa. To help optimize the wastewater management, Aarhus Vand and Aarhus Municipality have joined forces with City of Tshwane in a Strategic Sector Cooperation for a more water resilient city.

At traditional wastewater treatment plants, the energy produced is nowhere near enough to cover the operation of the plant. In Aarhus it is. Marselisborg WWTP has an energy self-sufficient far above 100 percent and the plant is in fact a power station, a bio refinery where energy is produced from wastewater.

Total energy renovation of the treatment plant at Egaa, just outside Aarhus, means that Aarhus Vand is setting new standards for developing treatment plants from energy guzzlers into energy producers.

We have reopened the cased Aarhus River so that people are once again able to enjoy the open water areas in the centre of Aarhus. The opening of the river is also an important part of Aarhus Vand’s project about flood prevention and preventing wastewater from overflowing into lakes, streams and bay.

At Aaby and Marselisborg Wastewater Treatment Plants Aarhus Vand extract phosphorus from the wastewater and sell it as valuable fertiliser under the name PhosphorCare.
