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.

Ghana Water has reduced their water loss by 8% in the city of Tema. Technology and knowledge of leak detection has been transferred from Aarhus Vand to Tema. The gains are that employees working with water in Tema are able to actively detect and repair leaks now.

Aarhus Vand supplies drinking water of the best quality merely by filtering and aerating the water on its way to the citizens’ taps. However, we can only do this because we think ahead and always take the groundwater into consideration.

The United Nations expect that the world will use up to 40 percent more water in 2025 than in 2015. At Aarhus Vand we use asset management to reduce water loss.

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.

At Aarhus Vand, one of our primary focuses is on developing new and innovative solutions to improve the sustainability and efficiency of the water sector.

You might not think about it when you open your tap and have a glass of water. How did our water get so clean? Operations assistant, Anders Sørensen has the answer. He makes sure that the citizens of Aarhus Municipality have clean tap water.

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 get our tap water from our ground water resources and, therefore, it is essential that we take care of these resources before they run out. At Aarhus Vand, we are doing everything we can to ensure that our resources will last for many decades to come.

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.

The new and improved Bederværket is built as an integrated part of the surrounding areas. With this new facility, it is possible for the public to follow the way of the water – from groundwater to tap water.

Up to 10,000 households’ washing machines and toilets in the suburb Nye – near the city of Aarhus - will soon use rainwater instead of drinking water. This is estimated to cut water consumption by as much as 40 percent.

Truelsbjerg Waterworks in the northern part of Aarhus sets new technological, architectural and operational standards for waterworks. It has started a trend in new design that has inspired several water utilities in Denmark.

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