Buttstedt Wastewater Treatment Plant, Büttstedt, Thüringen, Germany

The Buttstedt wastewater treatment plant is located in Büttstedt, a small town in the Thüringen region of Germany. It serves a population of approximately 1,620 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, far from coastal areas, and its operational status is listed as closed. As a secondary treatment facility, Buttstedt would have met the EU UWWTD requirement for biological treatment of organic matter. The plant's designed capacity of 2,600 m³/day indicates it was sized to handle peak flows from the local community. The annual discharge volume of 409.98 m³ suggests it operated below capacity, typical for small rural plants with seasonal variations. The treated effluent from Buttstedt would have been discharged into a local watercourse, likely a small stream or river within the Weser river basin, which ultimately drains into the North Sea. The plant's closure may reflect consolidation of wastewater services in the region, with flows redirected to a larger facility. The local watershed supports agricultural and ecological functions, and proper treatment helps protect downstream water quality.

The Buttstedt plant is located in the Weser river basin, with treated effluent likely discharging into a tributary of the Unstrut or Leine rivers, which flow into the Weser and eventually the North Sea. The region is characterized by agricultural land use and small watercourses that support aquatic life and biodiversity. Even small treatment plants play a role in preventing nutrient pollution and maintaining the ecological health of downstream waters.
