The Herbringhauser Talsperre (until 2006 “Obere Herbringhauser Talsperre”) is a drinking water dam in the Bergisches Land ( North Rhine-Westphalia ). It was built from 1898 to 1901 by the city of Barmen , which was still independent at the time and is now part of Wuppertal . The Herbringhauser Bach is dammed . The operator was the Wuppertaler Stadtwerke until December 31, 2015 ; on January 1, 2016, the dam became the property of the Wupperverband , which had acquired it from WSW together with the Kerspe dam for EUR 46 million.

description

In the early days of dam construction from the end of the 19th century to the beginning of the 20th century, it was customary in Germany to name dams not after their dammed up water, but after the town they were built to supply. As a result, the Herbringhauser Talsperre is also referred to as the Barmer Talsperre in contemporary literature . It was later renamed to the current naming convention.

A few kilometers below the dam, just before the Herbringhauser Bach flows into the Wupper, there was another reservoir , which was abandoned in 2006 and was called the Lower Herbringhauser Dam to distinguish it. The much larger dam located in the upper reaches is now only referred to as the "Herbringhauser dam" after the lower reservoir was torn down.

In addition to supplying drinking water , the dam also serves to store process water and provide flood protection for the central Wupper area. The Herbringhausen waterworks is located directly below the dam . The Kreuzmühle pre-basin of the Herbringhauser Dam completes the reservoir system.

history

At the end of the 19th century, the city of Barmen was looking for a way to improve the inadequate drinking water supply from Ruhr bank filtrate . It was decided to build drinking water reservoirs for this purpose. Since there was no suitable place in the city for such a dam construction, the surrounding area outside the city limits was explored. After an inconspicuous investigation of the area, the choice fell on the Herbringhauser Bachtal, which was located in the area of ​​the rural community of Lüttringhausen .

From 1896 onwards, the city of Barmen bought the 140 hectares of land required largely secretly and without revealing the purpose through a middleman . This middleman was the mayor of Lüttringhausen, Richard Gertenbach , who negotiated the annual withdrawal of 100,000 m³ of drinking water from the dam, starting in 1906, to supply his community. The still existing water-powered iron hammers on the lower reaches of the Herbringhauser Bach were also bought in order to avoid legal disputes about their water supply. Due to Gertenbach's negotiating skills, the land was acquired without coercive measures such as expropriations.

Construction began in 1898 and was completed in 1901. A Beyenburg contractor named Rothstein was commissioned with the construction . The dam is a gravity dam made of quarry stone masonry and was built according to plans by Prof. Otto Intze . The subsoil consists of slate . The stones for the wall and the filter plant underneath were broken in the Zur Gute Hoffnung quarry near Niederdahlhausen . A 2450 m long narrow-gauge railway line along the Herbringhauser Bach was set up to transport the building material .

In 1904 a restaurant was built above the dam near the shore line, which mainly attracted visitors as guests. This restaurant, known as Haus Barmen , was demolished in 1976 due to stricter water protection guidelines. The area around the dam was also fenced and reforested at a distance of approx. 100 m for water protection reasons. Courtyards like Seringhausen and the Kreuzmühle in the water protection area were acquired and laid down on occasion.

In 1926/27, shortly before the Herbringhauser Bach flows into the Wupper, the Lower Herbringhauser Dam, which was put into operation in 1928, was built. It was supposed to store more drinking water for which there was no free capacity in the Barmer dam and to pump it back into the upper dam. The pump house below the dam, which was removed in 2006, is still preserved and is a listed building. The hamlet of Hilgershammer , consisting of several residential buildings, had to give way for their construction .

When the law on the municipal reorganization of the Rhenish-Westphalian industrial area was drawn up in 1928 and the founding of the city of Wuppertal was decided in it, the Herbringhauser dam was the decisive reason why the area around Herbringhausen was separated from the municipality of Lüttringhausen and added to Wuppertal.

The dam wall has been rebuilt and renovated several times in the course of its operation, most recently from 2000 to 2003. The wall was given a water-side geomembrane seal (plastic sealing membrane), which was applied to the existing shotcrete shell. It also includes an inspection walk and drainage . Sealing with plastic (so-called Carpi system ) is a new feature for German dams.

In 2004 the entire core structure of the rapid filter system, the dam wall and the upstream backwater area were placed under monument protection.
