A 3 ha linear SUDS wetland park harvesting rainwater across three city-centre streets for park maintenance, aquifer recharge, and drought-season reuse.
The Green axis Cristobal de la Moura features a sustainable urban drainage system that harvests rainwater from the city catchment and channels it into a 30,000 m² linear wetland park across three streets in Barcelona city centre. Collected water supports park maintenance, groundwater aquifer recharge, and local uses such as plant irrigation and street cleaning during drought seasons, reducing reliance on tap water. The showcase tests how an urban wetland park as a nature-based solution can enhance urban water management, foster water recreation during drought periods, and deliver biodiversity and wellbeing benefits by transforming grey infrastructure into green public space.
Socio-economic monitoring shows how people access, use, perceive, and engage with this showcase. It combines partner-uploaded social indicators with geo-based survey results where available.
