Site: Metropolitan area of Centro Occidente, in Colombia, with >700,000 inhabitants.

Situation: Colombia needs innovative and cost-effective urban wastewater treatment, because many municipalities do not have any. In addition, river basin restoration is crucial in Colombia, due to its ecological value and use as a main source of potable water. NICE will contribute to improving water quality of rivers in Pereira, namely Otún River.

Solution: Two hybrid subsurface wetland pilots to treat 2 m3/d of wastewater and 10 m3/d of river water.

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).
