Therefore the Water Board has decided that this pumping station will be the first of their four main pumping stations to be adjusted to present-day requirements and equipped with modern techniques. Tauw will sign for the design and project management. Since Tauw is in charge of both the design and the project management, unforeseen circumstances during implementation can be responded to optimally. In 2011 the Katwijk pumping station must have the capacity to discharge 75 m³/s into the sea in periods of large-scale excess water at high sea water levels. Now this is only 54 m³/s. Under normal circumstances the pumping station should be able to discharge 94 m³/s to sea. In this respect Rijnland also expects to be able to store water in the near future at the water storage locations in the Haarlemmermeerpolder and the Nieuwe Driemanspolder near the city of Zoetermeer during severe precipitation. The measures to be taken are necessary in order to cope with the climate changes. More precipitation, urbanization with increased paved surfaces and sealevel rise as well require actions. In order to provide enough capacity for the pumping station, a fourth pump unit will be built next to the existing pumping station. The substructure and the superstructure of this storage pumping station, dating from 1954, will be preserved and reused. In addition, the existing pump drives (two diesel engines and one electric motor) will be replaced by new electro-motors and several renovation activities will take place. When the operations are finished, there will be four, electromotor-driven, hydraulically identical pump units. Fish migration For the upstream fish migration facilities are made both at the pumping station and at the outer discharge sluice. The downstream migration will take place via the pumps. Because of the large impeller passage and low impeller speed fish injury hardly can takes place. Allplan application 3D-Model In view of the complexity of the design geometry it was decided to create the drawings in 3D. During the earlier design phases of the pumping station all drawings had been rendered in Autocad. During these phases it Extension and renovation ‘Katwijk pumping station’ In order to provide enough capacity for the pumping station, a fourth pump will be built next to the present pumping station. In this way the design and the superstructure of the storage pumping station, dating from 1954, will be preserved. In addition, the existing diesel engines will be replaced by electro-motors and several renovation activities will take place. When the operations are finished, there will be four, electromotor-driven, hydraulically identical, pump units.

The software has been used in an ideal manner for the complete design process: from the initial 3d model to the fully detailed reinforcement drawings. The benefits of BIM are also strongly manifested in the project.” Quote of the Jury
