It is the last section of the approximately 51-kilometer-long gigantic sewer from Dortmund to the wastewater treatment plant at the Emscher estuary in Dinslaken. The section of the sewer is adjacent to the landscaping of the new Emscher dike in Holtener Bruch in Oberhausen. After almost nine years, the sewer is almost completed. It lacks then only the last three kilometres from the sewer to the last wastewater treatment plant before the Rhine. The serwer is designed as a double frame profile using the cut-and-cover construction method and partially laid to form an arch. The Emscher sewer is completed in the Essen area. In September 2018 it was completely flooded up to Bottrop. A full commissioning is planned for 2020. All services related to the object and specialist planning have been provided for the project. The video of the Emscher Water Management Association shows the construction process of the serwer.
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.
