The data refer to the administrative Hofsteder Bach, which is made up of Hofsteder Bach and Grummer Bach .

For decades, the Hofsteder Bach in Bochum was primarily used for sewage disposal. The majority is piped, the rest straightened and embedded in concrete. Only now, as part of the ecological reconstruction of the Emscher system , is the above-ground part of the Hofsteder Bach (approx. 1.8 km) being renatured.

geography

The visible part of the brook begins on Hofsteder Straße in Hofstede and essentially flows west. Shortly before the former clarification ponds, it makes an arc to the northwest and, together with the Marbach, forms the Hüller Bach . This crosses under the Rhine-Herne Canal in Gelsenkirchen and finally flows into the Emscher .

history

In the 19th century, the Hofsteder Bach was much longer than the part visible today. It originated near Altenbochum , flowed west to Bochum and was routed underground through the city center. Then it turned north and meandered through a wide meadow valley to Hofstede , where the Grummer Bach flowed into it and the Bulksmühle had to be driven. It flowed further west and finally united with the Marbach .

It was already the case at the beginning of the 20th century that the two brooks, Marbach and Hofsteder Bach, took up the water from Bochum's street canals and - after it had been cleaned in clarification ponds - led it into the Emscher .

administration

In the water management of North Rhine-Westphalia, the nowadays still visible part of the Hofsteder Bach and the Grummer Bach have been combined to form a flowing water with the number 277242 and the name Hofsteder Bach. It consists of approx. 1.8 km old Hofsteder Bach, an approx. 1 km long piped section and approx. 2.7 km of Grummer Bach.

ecology

At the moment an "ecological improvement from km 0.00 to km 1.80" is taking place in the Hofsteder Bach. The future sewer is already ready - the water from the Grummer and Hofsteder Bach will also be temporarily channeled through it. The stream bed on the surface of the earth is dry and is being renatured. When the construction work is finished, the stream can come out again.
