Sustainable drainage systems (SUDS) – Park of Joan Reventós

Creation of new green areas, Creation of semi-natural blue areas, Maintenance and management of urban nature, Transformation of previously derelict areas

The space has conserved the vegetation and a drainage system has been constructed that allows to reuse the torrent water for irrigation. The councilor of Sarrià Sara Jaurrieta explained that "both the filtered water and the one of a collector that goes below is used" and it turns it over to the water table (Ref 5). Goals for the project are water absorption and filtration (Ref 1, 2 and 3). - Bring nature closer to citizens, improving the quality of life and creating environments healthier (Ref. 7)

The rearrangement has been done respecting the existing vegetation and the space generated by the torrent. Thus, priority has been given to the conservation of the natural features of the park, and also original plantations have been planted in the Sierra de Collserola, which is very close to the area of the Park (Ref 3). The system allows the collection of rainwater through different types of drainage pavement that filter water and purify it at the same time. Once filtered, the water is brought back through the subsoil and infiltrates to the ground. In case of heavy rains, it would be held in the zone of detention or in flood areas created for this purpose.
