Water utilities in Denmark are struggling with rising problems of hydrogen sulphide in the sewers. To solve these problems, Aarhus Vand has partnered up with Envidan and made a sustainable filter that uses mussel shells to break down the hydrogen sulphide without chemicals.

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.

The company Zediment delivers drone-based scannings of the capacity of reservoirs at wastewater treatment plants and in stormwater basins. This solution is the first of its kind and can save the water utility huge operational costs.

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.

Water managers often lack coherent and updated information that clarifies the complex water system interactions to a degree where vital correlations and dependencies are known and understood.

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 we have extracted phosphorus from the wastewater. Over a decade this has been sold as a valuable fertiliser under the name PhosphorCare.
