The Dorneburger Bach , also Dorneburger Mühlenbach, is a right tributary of the Hüller Bach in the Ruhr area , it belongs to the river system of the Emscher .


The Dorneburg Brook has its source in the so-called "Zillertal" (named after a former excursion restaurant) in the Hiltrop district of Bochum . It is created here by the confluence of three source streams, a fourth source stream has dried up due to the development of the catchment area. The headwaters, the stream valleys and the adjacent, wooded slopes are designated as the Tippelsberg-Berger Mühle nature reserve. The Berger Mühle was a high medieval water mill, a half-timbered house has been preserved here to this day. Large sections of the stream served as an open sewer system for draining the settlement areas and industrial plants. Today, diluted wastewater (canal cuts from the mixed system ) is discharged into the stream via two rain retention basins a little above the city limits of Herne-Bochum when there is heavy rainfall when the diameter of the canals is insufficient due to the high amount of water. The upper course above is free of wastewater.

Within the urban development, the stream often runs underground. In Herne-Eickel the former moated castle Haus Dorneburg and the mill of Haus Nosthausen were on the stream. On the outskirts Gelsenkirchen-Bismarck and Herne-Wanne he crosses the Erzbahntrasse before the Hüller Bach opens.

Ecological renovation

In the 1920s the Dorneburger Bach was put into a concrete channel, straightened and in many places laid underground or overbuilt. In the days of active mining , there was no alternative to this Köttelbecke (colloquial language in the Ruhr area), as a closed sewage system could not be used due to mining damage . The Emscher and its tributaries became an open sewage system, only the upper reaches of the water bodies still had a natural course.

In 1996, the operator of the sewage system, the Emschergenossenschaft , and the municipalities began to renaturate the stream as part of the project to convert the Emscher system . Since then, the wastewater has been channeled and the stream ecologically renewed. This project has already been implemented as far as the inner-city area of Herne-Wanne . The crossing under the Wanne-Eickeler Hauptbahnhof and parts of Herne-Wanne has been completed since 2012 . In this area an 830 m long water passage with an outside diameter of 3.4 m has been built.
