Herzog and De Meuron, Purification Basins, Barcelona 1992

The project concerns the construction of a new interface between the city and the sea through a system of wastewater purification basins on the site of a disused railway line at the end of the Diagonal street. The basins are designed according to sinusoidal paths that follow the old dune alignments; an elevated path allows the observation of the different types of vegetation in the water.
