 Grummer Bach, designed close to nature |
||
The Grummer Bach in the Bochum district of Grumme has for many decades been predominantly "built out of the natural environment", largely piped, largely straightened and embedded in concrete. In some places, however, especially in the area of the Grummer Teiche , it is designed "close to nature" - the streambed is hardly paved, the bank has trees typical of the location, some dead or fallen trees are allowed to stand or remain.
geography
The Grummer Bach comes to light for the first time in Hiltrop . After less than 200 meters on the surface, it crosses the high-altitude former railway line between the former Lorraine colliery in Gerthe and the Bochum steelworks on Castroper Strasse. Then it flows further west through a wide, water-rich valley between Güstenberg and Kötterberg (in the north) and Böckenberg and Böckenbusch (in the south). It is dammed several times to protect against flooding. The retention basins are quite shallow and look almost natural - the Grummer ponds are a popular local recreation area. From the south, the Grummer Bach has three tributaries: the Rottmannsbach, the Schmalebecke and the Albecke - the latter is completely piped. The Grummer Bach himself disappears in a tube and flows into Hofstede underground in the Hofsteder Bach.

history
In the 1950s, the source of the Grummer Bach, formerly also known as Grumbecke or Grume , was still visible: “West of Grümershof - today Benking in Hiltrop - there is a spring whose water runs first in a southerly and then in a westerly direction in the valley floor. It's the Grumbecke or the Grummer Bach ... “In the Middle Ages, it drove the Grummer Mühle and, after its confluence with the Hofsteder Bach, also the Bulxmühle. The Hofsteder Bach, also called Schmechtingsbach, came from the south, from Bochum - its source was near Altenbochum.
administration
In the water management of North Rhine-Westphalia, the Grummer Bach and part of the Hofsteder Bach have been combined to form a flowing water with the number 277242 and the name Hofsteder Bach. This new Hofsteder Bach consists of around 1.8 km old Hofsteder Bach, around 1 km of piped flowing water and around 2.7 km of Grummer Bach. At the moment there is an “ecological improvement from km 0.00 to km 1.80”, that is, at the old Hofsteder Bach. The planned renaturation of the Grummer Bach has not yet started.
