Kahlenberg return pumping station

The Kahlenberg return pumping station

The Kahlenberg pumping station is the third of the Ruhr's eight pumping stations .

This chain of pumping stations can fill the water level of the Ruhr over a height difference of 40 meters from the Rhine ( Rückpumpwerk Duisburg ) to Essen-Horst (at the Horster Mühle hydropower station ).

location

The return pumping station is located in Mülheim an der Ruhr , 13 kilometers from the river confluence with the Rhine on the lock canal between the Dohn island with the Broicher Schlagd and the lock island of the Ruhr lock Mülheim .

The return pumping station

Two pumps with a total motor output of 808  kilowatts and a delivery rate of 9000 liters per second can, if necessary, pump the water 7.95 meters back into the upper water .

history

The return pumping station, made of Ruhr sandstone , was completed after 1929. The plans came from the architects Arthur Pfeifer and Hans Großmann , who had already designed the adjacent Kahlenberg hydropower station (1925) and the Mülheimer Stadthalle (1926).

The purpose of the pumping station is to ensure the drinking water supply. That is why it was decided in the 1930s to build the return pumping station to allow the river to flow "backwards" if necessary. The last time that happened was in the 1950s. Today only one operational inspection is carried out annually.

In 1988 the building was renovated together with the Kahlenberg hydropower station and placed under monument protection. Until 2011, it was represented as a station on the Route of Industrial Culture in theme route 12 - Past and Present of the Ruhr , and in 2016 it was included in theme route 28 Water: Works, Towers and Turbines .
