Aarhus
Site: Medium-size city with ~256,000 inhabitants - second largest in Denmark.
Situation: Underwent urban river restoration. After being piped for a long time, Aarhus River was resurfaced, and acts as a green and blue corridor through the city. Further flood prevention measures have been taken. NICE will contribute to the improvement of river conditions by testing nature-based solutions for river basin restoration. In addition, NICE wastewater treatment will be tested in cold winter conditions.
Solution: Two hybrid subsurface wetland pilots will be installed in Aarhus: one to treat 2 m3/d of wastewater and the second for river basin restoration of 10 m3/d.
The NICE Urban Real Labs are ideal test beds for nature-based solutions for circular urban water solutions, as they have varied geographical, environmental and socioeconomic characteristics.
The Urban Real Labs cover a wide range of climate zones: tropical and subtropical (Pereira and Turin), Mediterranean (Talavera, Algeciras, Benalmádena, Lyon, Cairo), transition climate with extreme temperatures (Madrid), oceanic (Vigo, Aarhus), and Baltic (Gdansk).
