14 business partners have joined together in an EU project to create "Water Living Lab" - an interdisciplinary knowledge and innovation environment that provides the opportunity to develop, test and demonstrate water technology solutions that support a sustainable and resource-conscious supply.

HeyPipe™ is a new digital platform that across all supply types gives unique 3D documentation of the underground infrastructure. Aarhus Vand has founded the company in order to receive better and more valid data.

An important step towards a CO2 neutral water sector is to gain more knowledge about how we measure and reduce greenhouse gases. Supported by the Danish Environmental Protection Agency, the ARES project, aims to uncover new knowledge about the two greenhouse gases methane (CH4) and nitrous oxide (N2O) in sewer systems and at wastewater treatment plants.

Aarhus Vand has joined the Horizon Europe project, WATERUN, to improve the knowledge on stormwater quality in Aarhus and the cleansing effect of green infrastructures. With more than 10 years of experience in establishing and operating blue/green infrastructure, we look forward to becoming wiser on the cleansing effect of open storm water solutions.

Aarhus Vand has established a leak detection field. Water operators can train and become educated in finding leaks in water pipes. The field also works as a test and demonstration of Danish water technology.

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.

The new company Utilizero is a partnership between Aarhus Vand and DHI. It has been established to help utilities reduce carbon emissions and energy usage at wastewater treatment facilities from the solid experiences and solutions for automated process management, we have here in Denmark.

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 we are very engaged in business creation and how to improve areas within the field of water supply. Therefore, we created the company DRYP together with MONTEM.

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 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.

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.
