The Kettwiger See , located in the southern part of the Essen district of Kettwig , was built by the Ruhrverband from 1940 to 1950, after the Hengsen reservoir and in front of the Kemnader See , as the penultimate of the six Ruhr reservoirs . The Kettwiger See is the last reservoir of the Ruhr downstream . It is about six kilometers behind the largest, the Baldeneysee .

Technical details

The Kettwig reservoir with a volume of 1.42 million cubic meters is used for river clarification through biological self-cleaning.

The weir with two 44 meter wide weir openings dams the Ruhr 6 meters high. It can discharge floods of up to 2200 cubic meters / second. A return pumping station with an engine output of 588  kilowatts is used to return 6000 liters of water per second to Lake Baldeney. The chain of return pumping stations in the Ruhr can use it to pump water back from the Rhine into the reservoirs in particularly dry times in order to continue to guarantee the drinking water supply.

The hydropower plant with an output of 5300 kilowatts from three Kaplan turbines was built for the Rheinisch-Westfälische Elektrizitätswerk . An annual average of 16 million kilowatt hours are generated. A lock for the Ruhr shipping was built for ships up to 300 tons.

The Kettwig Ruhr Bridge over the weir for pedestrians and road traffic was created for a bridge community under the leadership of the Ruhr coal district settlement association .

With the damming of the lake and the establishment of the new weir, the Kettwig lock , now on the right bank of the Ruhr, was also rebuilt. With a storage height of 6.2 meters, this has a length of 42.41 meters and a width of six meters.

The Ruhr reservoirs, the lock and the Kettwig run-of-river power plant are part of the route of industrial culture .

Trivia

The Kettwig Reservoir , which opened in 1945 under the name of Kettwig-Pusch , has been named after the lake since 1968. The breakpoint is on its south bank. But in fact there are all the development facilities of the Kettwig reservoir, z. B. the pedal boat jetty or the jetty of the White Fleet on the north bank.
