City wetland park for surface water co-creation in Barcelona, Spain

In the heart of Barcelona, a new urban wetland park is redefining how Mediterranean cities manage water. Spanning 30,000 m² across three city streets, this system captures rainwater through sustainable urban drainage. The water is stored for irrigation, street cleaning, and groundwater recharge during drought periods.

Beyond water reuse, the park enhances biodiversity, transforms grey spaces into green ones, and offers recreational and wellbeing benefits to citizens. With two phases already completed by the municipality, the next expansion within our project will serve as a model for urban water resilience through nature
