A partnership collaborating on advancing the future of environmentally friendly wastewater treatment and leading the green transformation of the sector.
WTA's purpose is to create bridges between Denmark and the rest of the world in terms of increasing Danish water export.
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.
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.
Increasing rainfall means that pipe capacity is too small in many places, with excess water – a hazardous mixture of wastewater and rainwater – flowing into lakes, streams or sea untreated. The excess water also causes flooding of cellars, roads and green areas. In other words, we lack space in our sewer system, and Aarhus Vand is doing something about this by seeing surface water as a valuable resource.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
