Site: Medium-sized city with ~462,000 inhabitants on the Baltic coast of northern Poland. Its metropolitan area, including the cities of Gdynia and Sopot, and minor towns in their vicinity, has a population of ~1.5 million inhabitants.
Situation: Its cold Baltic climate (with temperatures that can drop under -20 ºC), sporadic heavy rain and flooding in summer will be a chance for validating NICE stormwater treatment under difficult conditions, verifying its resistance to low temperatures and reduced water flow.
Solution: Stormwater treatment of 5 m3/d with rain gardens.
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).
