Straussfurt Wastewater Treatment Plant, Straußfurt, Thüringen, Germany

Straussfurt is a wastewater treatment plant located in Straußfurt, in the district of Sömmerda, Thüringen, Germany. The plant serves a small population of approximately 3,192 residents and operates with advanced treatment technology, ensuring high-quality effluent. With a designed capacity of 6,000 m³/day and an average discharge volume of 552.04 m³/day, the plant operates well below its capacity. As a German facility, it complies with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size, but the plant exceeds this standard with advanced treatment. The treated wastewater is discharged into local water bodies that eventually drain into the Unstrut River, a tributary of the Saale, which flows into the Elbe and ultimately the North Sea. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from nutrient pollution.

The plant discharges into the Unstrut River basin, which feeds into the Saale and Elbe rivers before reaching the North Sea. The region is characterized by agricultural land use, making nutrient removal critical to prevent eutrophication in downstream waters. The advanced treatment helps reduce nitrogen and phosphorus loads, supporting the ecological health of the Elbe estuary.
