Gebesee Wastewater Treatment Plant: Thüringen, Germany

The Gebesee wastewater treatment plant is located in the town of Gebesee, in the district of Sömmerda, Thüringen, Germany. It serves a population of approximately 2,572 people, placing it in the small agglomeration category under German and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. With a designed capacity of 3,300 m³/day and an actual discharge volume of 450.80 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local water system, which ultimately drains into the Unstrut River and then the Saale River, a tributary of the Elbe. This region is part of the Elbe basin, supporting diverse aquatic life and contributing to the ecological health of the North Sea via the Elbe estuary.

The plant discharges into the Gera-Aue area, a floodplain of the Gera River, which flows into the Unstrut River. The Unstrut joins the Saale, a major tributary of the Elbe River, which empties into the North Sea. This watershed supports diverse aquatic habitats and is important for migratory fish species. The advanced treatment helps protect downstream water quality in this ecologically sensitive region.
