The Deininghauser Bach is an approx. 10 km long watercourse that drains an approx. 20 square kilometers large catchment area in Castrop-Rauxel and flows into the Landwehrbach or the Emscher . It arises from several sources in the vicinity of the former Graf Schwerin colliery , today's Schwerin dump . The discharge, which is stable at around 30 liters per second even in dry conditions, is more salty than other streams due to the overburden rock.
history
In the 1930s, due to mining, the brook was rebuilt and straightened into a partially open and partially underground sewage system right into its source areas. Both wastewater and pure water were drained off together, the gradient was made significantly steeper, and the course was expanded with invert shells.
modification
As part of the International Building Exhibition Emscher Park , the stream was selected as a pilot project for the conversion of the Emscher system in IBA green corridor F. The Emschergenossenschaft has been dismantling the building since 1992 . The project is still the largest water project within the Emscher system despite the redesign of the actual Emscher canal that has now started. Wastewater and pure water were initially separated and pure underground sewers and rainwater retention basins above ground were created. The stream will be renatured section by section from the upper course of the water, the steep banks will be flattened, the course of the stream will be rebuilt in large turns and the area will be planted in a natural way.
The already partially existing cycle path will be expanded and the crossings of the stream with streets and public spaces will be integrated into the surrounding area by bridges, path connections and rest areas for pedestrians and cyclists. The Deininghauser Bach runs through a nature reserve between Nierholzstrasse and the Cologne-Mindener Railway . In Castrop-Rauxel, the brook on Schulstrasse will come to the surface again and from then on will be designed as urban water.
The renovation project will cost 26.6 million euros as planned, it will be financed by contributions from the Emschergenossenschaft and 80 percent by the state of North Rhine-Westphalia and will be completed in 2017.
