DE As part of the ecological reorganisation of the main course of the Emscher, the Emschergenossenschaft is having a flood retention basin (HRB) built in the Dortmund district of Ellinghausen. In future, the "HRB Ellinghausen" is to provide a total retention area with a retention volume of approx. 1.5 million m³ in conjunction with the neighbouring "HRB Mengede".
With an excavation area of almost 25 hectares, an excavation volume of over 1 million cubic metres of soil and an excavation depth of up to 6 metres, the flood retention basin will make a significant contribution to flood protection for the towns located along the main course of the Emscher. For the construction project, 3 separate individual basins were initially excavated from 2013 to create the so-called intermediate state. The northern basin section C was already completed in 2019; for the final construction of the southern basin sections A and B, the remaining embankments ("Rehnen") are currently being removed so that the final structural state of the HRB-Ellinghausen will be reached shortly.
The Emscher, which was straightened during industrialisation, will meander through the basin as part of the final expansion by excavating a new riverbed. Alternating between low and high flow rates of the Emscher, the retention basin will take on a floodplain-like character.
For more than 10 years, TABERG Ingenieure GmbH has been supporting the large-scale project for the construction of the "HRB Ellinghausen" with both planning and technical expertise. All services relating to soil management, geotechnical implementation support and construction supervision / site management have been provided in full by TABERG Ingenieure GmbH to this day.
