The steel building – whose shape recalls an upside down drop of water – is softly integrated into the landscape and with the creation of a series of wet areas, it contributes to providing the ideal habitat for a number of species of migratory birds. Among the various measures taken to minimise the plant’s environmental impact are the skylights opened in the long green roof (3,200 square metres) that allow light to filter down to the water treatment plant located underground, the reuse of materials resulting from the demolition of the previous plant, and the building’s heating and cooling system.
