Costing 60 million Euro: Oberhausen Pumping Station on the Holtener Bruch is also currently known as the largest excavation pit in North Rhine-Westphalia. With a diameter of 45 meters and a depth of 45 meters, it is an important cornerstone of the Emscher conversion. The pumping station is one of the largest in Europe. "Supervising such a large and complex planning activity over such a long period of time is an incredible challenge, says Dipl.-Ing.Marc Althoff, the responsible Design Manager. The pumping station is part of the overall planning for the ecological transformation of the Emscher between Dortmund and Dinslaken and will annually feed approx. 170 million cubic meters of wastewater to the Emscher estuary waste water treatment plant. The architecturally accurate visual concept harmoniously integrates the building into the ecological reconstruction of the Emscher. The project comprises the provision of all services related to object and technical planning (structural engineering, technical Equipment)
By means of holistic optimization, Waste Water Treatment Plant Aachen-Soers has succeeded in reducing the enormous energy demand of the recovery by around 55 per cent. Together with DAHLEM, the Wasserverband Eifel Rur planned the modernization of the oxygen supply of the aeration tanks. The design was implemented at the beginning of the year, followed by the commissioning of the blower station mid-year. The RWTH Aachen accompanies the project scientifically. DAHLEM supported the process design, which was modeled in a 3D-planning and accompanied the award procedure. The enclosed article about the project provides detailed information about the modernization of the plant. The waste water treatment plant is also referred to as a nationwide model Enterprise.
