Local stakeholders: SEO/BirdLife, Municipality of Santander, IH Cantabria The selected area for the case study in Santander is called, “Las Llamas basin”. A hybrid system already exists of 7.3 km2 that includes two Nature-Based Solution: a wetland and a permeable car park. It is complemented by two conventional systems: a pumping station and a treatment plant. The main challenge today in the area is the potential collapse of treatment systems due to overflows (120 stormwater overflows event/year and a volume of 240 000 m3/year) and the gap in knowledge concerning Contaminants of Emerging Concern (CECs). Aerial view of Las Llamas Park Las Llamas Park Wetlands at Las Llamas Park Study different types of permeable surfaces (pavements, green roofs or gardens), and increase the wetland’s surface to maximise its potential benefits. Sample water in the inlet and outlet of the wetland to control water quality and ecosystem well-being and at the car park to identify the presence of CECs. Study the two traditional sites connected to the sewer system: pumping station and treatment plant. Characterise the entire urban drainage system and model positive consequences of the connection of new NBS.
