The Waste Water Treatment Plant (WWTP) of the Lower Bidasoa, in the municipal district of Hondarribia, is located in an area with a high quality landscape, in the vicinity of the of Higuer Cape lighthouse and the adjacent campground. This campground is the starting point of several rural pathways that run along the Mount Jaizkibel cliffs. Therefore, the main aim in the design of the civil engineering works was to attempt to minimise the visual impact by studying the situation of the different elements of the scheme, with a careful design of the buildings and other integrating elements, a suitable integration of the necessary dumps and a final restoration of the resulting landscape and the surrounding paths. The final result, reflected in the development plan, involves a compact distribution in which the sludge treatment tanks, which are larger and higher, are "concealed" between the hillside and the sludge treatment building. On the rest of the site the water treatment tanks (like swimming pools that hardly protrude above the ground) and the main buildings are laid out more freely.
• Access floor-plan to the Control building. • Aerial view of the WWTP. • Views of the main buildings, including the Pre-treatment and Blower Buildings, two simple rectangular volumes designed with a striking “u-glass” glazed walls with a horizontal pattern, and the Control Building, composed of three intersecting volumes in exposed concrete half-way up the hillside.
