Waldeck _ Sachsenhausen Wastewater Treatment Plant, Sachsenhausen, Hessen

Waldeck _ Sachsenhausen is a former wastewater treatment plant located in Sachsenhausen, a district of Waldeck in the Landkreis Waldeck-Frankenberg, Hessen, Germany. The plant was designed to serve a small population of 979 people, with a designed capacity of 2,750 cubic meters per day. It is now closed and no longer operational. As an advanced treatment facility, it would have provided tertiary treatment beyond secondary standards, including nutrient removal. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size (under 2,000 population equivalent) are typically required to provide appropriate treatment, though advanced treatment is often implemented in sensitive areas. The plant's closure may reflect consolidation of wastewater services in the region. Given its inland location in Hessen, treated effluent likely discharged into a local stream or river within the Weser or Rhine basin. The surrounding area is characterized by forests and agricultural land, with the Edersee reservoir nearby, a significant recreational and ecological feature.

The plant's discharge would have entered a local watercourse in the Weser or Rhine drainage basin, ultimately flowing to the North Sea. The region includes the Edersee, a large reservoir that supports aquatic life and migratory birds. The plant's advanced treatment would have helped protect downstream water quality in this ecologically sensitive area.
