Eschbach Dam

The Eschbachtalsperre is the first drinking water reservoir in Germany and is located in Remscheid, North Rhine -Westphalia. Is dammed Eschbach. This pioneering work of hydraulic engineering was an important milestone in the economic development of the city of Remscheid in their opening 1891.

Naming convention

In the early days of the dam construction end of the 19th century to the early 20th century - and even today in other areas - it was customary in Germany to designate dams not to their pent-up rivers, but according to the city for whose care they built were. Consequently, in contemporary literature the Eschbachtalsperre as Remscheid Dam known. Later it was renamed after today's naming convention.

History

The Eschbachtalsperre was planned by Otto Intze and built at the instigation of Remscheid industrialist Robert Boeker decided upon by the City Council in December 1888 from May 1889 to 1891 according to the Intze principle as gravity dam. The construction company was Wolf and Vering from Dusseldorf, the total cost amounted to 536,000 marks.

The water economically important building was the forerunner of a large number of other so-called Intze dams. In addition, other types of dams have been developed.

The dam was reconstructed in the period from 1991 to 1994. She has been reinforced, got a 35 cm thick concrete retaining wall and a patrol on the water side, a new drainage, a new extraction plant and new measuring devices.

Hydropower plant

In November 2012, the EEA built in the dam, a hydroelectric power plant for renewable energy after the project by the district government Dusseldorf was approved in October 2011. Using the predetermined drop height of about 18 meters and a maximum usable flow rate of 209 l / s, the turbine produces a power output of 29 kW 120,000 kWh of electricity per year. The power generated by this plant covers the energy requirements of the dam and the power beyond generated is fed into the public grid. The amount of electricity generated is approximately equal to the annual consumption of 35 average households and an annual CO2 saving of 65 tonnes.

Destination

The dam was from the beginning a popular destination. Prince Friedrich Leopold of Prussia visited the dam on July 15, 1897. Two years later, was Kaiser Wilhelm II on the spot praise for this structural engineering and water management pioneer.

1977, the trail was built around the lake to a trail to open up the dam for the visitors better. Not far from the loop road reminds Steinernes cross on a murder in ancient times. Along the dam leads a branch of the pilgrim route from Wuppertal- Beyenburg to Santiago de Compostela in Spain.

Dam composite

The dam is part of the waters of the composite Wupperverbandes. To ensure the drinking water supply of the city, there is since 1909 a direct, 15 -km-long pipeline to higher Neyetalsperre at Hückeswagen. The inflow station is some distance away from the dam. Another drinking water reservoir for Remscheid in the framework of this cooperation, the Great Dhünn dam.

Technical details

  • Exceptional flood retention area: 0.068 million m³
  • Operating room: 1.041 million m³
  • Reserve Room: 0.011 million m³
  • Dead space: 0
  • Absenkziel: 228.00 m above sea level. NN
  • Freeboard: 1,00 m
  • Building volume / total space: 1:45

Note: The ratio of building volume to the total storage space should be at 1:45. With the available data for the wall volume of 17,000 m³ and the total storage space of 1,120,000 m³, however you get to a smaller ratio, namely 1:66. This is possible if one assumes that the wall volume was increased when converting 1991-94 from 17,000 to 25,000 m³.
