ETAR (WWTP) of Alcântara, Lisbon
The intervention takes place as a moment of territorial reconfiguration of the morphology of the Alcântara Valley and as a confrontation between distinct and complementary natures – hillside space/covered space. Recovering lost continuities, both of visual and ecological systems “The intervention takes place as a moment of territorial reconfiguration of the morphology of the Alcântara Valley and as a confrontation between distinct and complementary natures – hillside space/covered space. The reconfiguration is carried out in the sense of finding a defined path for a landscape recovery of the valley, for a recovery of a consistent dialogue between the currently disconnected slopes and for a reestablishment of a relationship obstructed by the cut imposed by the current WWTP. Further downstream, the cut is accentuated by the urbanization and transformation, not yet carried out, of the slope exposed to the west. We speak of landscape recovery because we try to recover lost continuities, both of visual and ecological systems. The reminiscence of the archetypal morphology of the valley, the Alcântara Valley, is reinterpreted through the reconstitution of the terrain underlying the road corridors implemented on the half slope. Together with this action, we promote the constitution of the genesis of a pedological substrate capable of supporting a viable vegetation cover, rich in its floristic and imagery diversity, correspondingly decisive for the stabilization and consolidation, for the dynamic balance of the slope and, consequently, for its biological reactivation and for its full integration in the structural systems – visual, ecological, of the city’s landscape.” PROAP Start Date: 01.2005End Date: 01.2011Theme: Infrastructure Integration, Environmental RequalificationArea: 8,4 haClient: SimTejo S.A.
