Trebsen Wastewater Treatment Plant, Saxony, Germany

The Trebsen wastewater treatment plant is located in Trebsen/Mulde, Saxony, Germany, serving a population of approximately 4,850. The facility provides advanced treatment, ensuring high-quality effluent before discharge into the local water environment. With a designed capacity of 6,000 m³/day and an actual discharge volume of 740 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 mandates advanced treatment for sensitive areas and secondary treatment for all agglomerations above 2,000 population equivalent. The plant's treated effluent is discharged into the Mulde River, a tributary of the Elbe River, which flows into the North Sea. The Mulde River supports diverse aquatic life and is an important ecological corridor in the region.

The Trebsen plant discharges into the Mulde River, which flows into the Elbe River and ultimately the North Sea. The Mulde River basin supports a variety of fish species and aquatic habitats, and the Elbe estuary is a critical migratory route for birds and fish. Advanced treatment at this plant helps protect downstream water quality and ecological health.
