Erndtebruck Roespe Wastewater Treatment Plant, Birkelbach-Bahnhof, Germany

Erndtebruck Roespe is a former wastewater treatment plant located in Birkelbach-Bahnhof, a locality within the municipality of Erndtebrück in Nordrhein-Westfalen, Germany. The plant served a small population of 1,874 and had a designed capacity of 2,500 m³/day, with an average discharge volume of 474.26 m³/day. The plant provided advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant is now closed, and its wastewater is likely redirected to another facility. The plant's discharge likely entered the local watershed, which drains into the Eder River, a tributary of the Fulda River, eventually reaching the Weser River and the North Sea. The region is characterized by forested low mountains and supports diverse aquatic life in its streams and rivers.

The plant's discharge would have entered the Röspe stream, a tributary of the Eder River. The Eder flows into the Fulda, which joins the Weser River, ultimately reaching the North Sea. The watershed supports aquatic ecosystems in the Rothaargebirge mountain range, an area of ecological importance for migratory fish and other freshwater species.
