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.
Many municipalities have experienced how massive the damage caused by heavy rain can be in recent years. Targeted flood prevention against are heavy rainfall and flash floods is becoming increasingly important in this context. It represents a major challenge for the municipalities and is closely linked to the municipal adaptation to climate change. The establishment and implementation of coordinated rain risk management is on the one hand a new task. On the other hand, a flood preparedness system coordinated by the various specialist departments increases the complexity of planning and administrative processes and raises questions that are still unanswered. The project "Municipal Flood Prevention - Planners in Dialogue" of the German Institute for Urbanism (DIfU) in cooperation with DAHLEM and numerous experts from the various administrative departments of 15 German cities examined how flood prevention can be achieved within a network of municipalities. The project was funded by the German Federal Environmental Foundation (DBU) in the course of two years. The special feature of the project lies in the fact that the municipalities were represented in each case by the affected department (urban planning, environment, landscaping, roads, municipal water supply and sewerage, disaster control). In eight daily workshops, case studies were developed, where typical obstacles and problems but also possible solutions and success factors lie. Based on the practical experience of the municipalities, recommendations and solutions for administrative work within a municipality were summarized in a brochure. It serves as an aid to municipalities that want to get more involved in heavy rain protection and answers questions (FAQ) on the topics of organization, law, financing, planning/implementation and operation maintenance.
