The Sengbach Dam is a water - dam in Solingen . It is located in a secluded side valley of the Wupper not far from Burg Castle , between the Solingen villages of Höhrath and Glüder . The water reservoir located between the forests supplies the residents of the city of Solingen with drinking water. For this reason, the building is usually only called "Solingen Dam" in the vernacular. At times it was also referred to as the "Senkbach-Thalsperre".
In order to treat the surface water in accordance with the Drinking Water Ordinance and make it available to all Solingen households, the water from the Sengbachtalsperre is transported via a pipe with a diameter of 900 mm to the nearby Glüder waterworks , where it is processed into drinking water in several stages using filters and modern process technology.
The successful pioneer of German dam construction was commissioned with the construction of the facility: Otto Intze . The barrage made of Lenneschiefer , greywacke and trass mortar was inaugurated on May 28, 1903.
The wall of the main basin measures 43 m from the base of the foundation, the top of the wall is 178 meters long. The width of the wall is 36.6 m at the bottom and 5 m at the top. The gravity dam with a radius of curvature of 150 m holds back around 2.8 million m³ of water when it is fully flooded . The maximum water depth is 36.0 m with a water surface of around 200,000 m².
The reservoir, which extends mainly in a north-west-south-east direction, is between 100 m and 180 m wide and has a length of approx. 2.4 km.
The barrier structure of the pre-barrier consists of a stone embankment dam with an internal concrete core. The pre-basin is operated in full water. The overflow height is 148 m above sea level. The storage volume is approx. 100,000 m³. The maximum water depth of the fore basin is 4.5 m. The forecourt serves as a sediment basin .
