The Neyetalsperre is located in the north of the city of Wipperfürth near the village of Neye in the Oberbergisches Kreis in North Rhine-Westphalia .
description
The dam was built by the city of Remscheid between 1905 and 1908 as a drinking water dam . Several stone tools from the Stone Age were found.
The capacity is six million cubic meters. The Neye stream is dammed . The dam is a curved gravity dam made of rubble masonry based on the Intze principle .
The reservoir can be hiked around in about three hours. The paths run directly along the water and lead exclusively through the forest. The shortest way to go around the dam is around eleven kilometers long and is very popular with joggers and walkers. The larger Bevertalsperre and the small Schevelinger or Silbertalsperre are very close by . An underground tunnel leads from the Silbertalsperre to the Neyetalsperre and from there to the Bevertalsperre, known as the Bever block . The dam, which was built as a drinking water dam and has been in use for many years, has been operated as a process water dam since 2004. Drinking water should only be taken from it again if there is an acute shortage of water.
Today, EWR GmbH, the energy subsidiary of Stadtwerke Remscheid GmbH, is the owner of the Neyetalsperre, and the Wupperverband is responsible for operational management .
history
With the increasing demand for drinking water and due to the low precipitation in 1901 and 1904, the waterworks operators looked to expand their water supply system. Since the Neyetal was sparsely populated and samples certified good water quality, it was decided to build a dam with a curved weight stone wall near the village of Wipperfürth. After extensive planning and geological preparatory work as well as the approval process, the laying of the 14.9 km long pressure pipeline began in April 1907, construction of the wall began in August 1907, the construction company was Ernst Jüngst in Hagen . The trial jam began on November 23, 1908 . The barrier wall was finally removed on February 11, 1909 in the presence of the District President of Düsseldorf at three quarters of the water level. In the years 1964 to 1969 the dam wall with a crown length of 260 m was completely renovated.
Slurry disaster in the Neyetalsperre
On March 18, 2015, more than 1700 cubic meters of liquid manure flowed from the Halverner Hof Kotten via the Neye II tributary into the dam and collected in a bubble in front of the dam at a depth of 18 to 25 meters. A total of 100,000 cubic meters of water were contaminated. In order to prevent a major ecological catastrophe, 2 million liters of contaminated water were sucked out of the manure bladder every day and pumped through a pipeline to the Hückeswagen sewage treatment plant. Bank edge zones and parts of the Neyetalsperre are ecologically damaged. The perpetrator was sentenced to compensation in the civil proceedings and there was also a criminal case against the farmer, in which the accused farmer was acquitted for lack of evidence.
