The new sewage pumping-station is situated alongside the future Betuwe railway, as a part of the waste-water transportsystem Waalsprong/Arnhem-Zuid. It is mainly visible from a big distance and therefore has an eye-catching sculpture-like design. The rectangular main volume has a vertical waving anthracite masonry. On the contrary the other volumes are carried out in a smooth and shiny glued brick-work. The difference in texture between the two brick façades creates a tension in the appearence of the building. A somewhat mysterious appearence, whereby the play between light and shadow constantly evokes a different image.
