Climate adaptation
Surface water and cloudbursts
Our sewer system is built for Danish weather conditions, which in the vast majority of cases are sufficient. But in the event of cloudbursts, the system is challenged and the rain ends up on the roadway and in low-lying areas.
One way to control the massive amounts of rain is through climate adaptation, which we have been working on since 2012. With climate adaptation, we try to delay the water by creating rainwater basins for temporary parking or we create space for the water to flow. The goal is to prevent the water from causing damage to the city.
At any construction project or sewer separation project, the value of climate adaptation is considered.

Separation of rainwater and wastewater
At Aarhus Vand we have an ongoing project separating rainwater and wastewater in large residential areas around the inner city. We disconnect rainwater from the combined sewer system to ensure optimal capacity and maintain water quality. In our attempt to adapt the city of Aarhus to climate change and avoid damage to properties or infrastructure following heavy rain, we handle rainwater on the surface – wherever it is possible. In some areas though, rainwater is lead through new pipes.
By handling rainwater primarily on the surface, we are able to separate large areas for the same amount that it would cost to lay pipes. In addition, it offers a unique opportunity to use rainwater in a new way – for recreational purposes.

Projects with climate adaptation
We make rainwater a visible element in the form of rainwater lakes, rainwater beds and rainwater drains. The municipality of Aarhus has a vision of making Aarhus an even more attractive place to live. We support this ambition with our climate adaptation projects where recreative spaces for better health of the citizens are established.
Aarhus Vand has carried out two major climate adaptation projects with rainwater being handled on the surface – one in Lystrup north of Aarhus and one in Risvangen in the northern end of Aarhus. In Lystrup all 12 climate adaptation solutions involved surface treatment. In Risvangen, rainwater is handled in a combination of surface handling and pipes. In Malling, a small town to the south of Aarhus, a new urban area has been planned, with the establishment of a drainage system for rainwater handling based solely on a surface solution.
