The dam was the first drinking water reservoir built in the Bergisches Land region.
It is a masonry gravity dam, a construction method largely superseded by concrete dams in later projects.
The reservoir serves as a backup supply, as the primary drinking water for Solingen is now sourced from the Große Dhünntalsperre.
The surrounding landscape is part of a protected water conservation area, limiting human activity near the water's edge.
A major renovation of the dam wall and sealings was completed in the early 2000s to modernize structural integrity.
The Sengbachtalsperre is a masonry gravity dam completed in 1903, located in the Bergisches Land region of North Rhine-Westphalia. It functions as a drinking water reservoir for the city of Solingen, operated by the Stadtwerke Solingen. The dam wall is constructed from quarry stone and stands 41 meters high above the valley floor. It is embedded within an extensive forest area featuring a network of marked hiking trails. The reservoir holds approximately 2.8 million cubic meters of water. Visitors can hike the circular route around the basin, which provides views of the dam infrastructure and surrounding deciduous woodland. Swimming, fishing, and boating are strictly prohibited to protect the water quality. The area serves as a significant example of early 20th-century hydraulic engineering in Germany.
