Dahlen Wastewater Treatment Plant, Saxony | Germany

The Dahlen wastewater treatment plant is located in the town of Dahlen, in the Nordsachsen district of Saxony, Germany. It serves a population of approximately 2,891 residents and treats an average daily flow of 585 cubic meters, with a designed capacity of 4,000 cubic meters per day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment ensures high-quality effluent suitable for discharge into sensitive environments. The treated water is discharged into local watercourses that eventually drain into the Elbe River basin. The Elbe flows through Germany and into the North Sea, supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's advanced treatment helps protect these downstream waters from nutrient pollution and other contaminants.

The plant discharges into the Elbe River basin, which flows through central Europe to the North Sea. The Elbe supports diverse aquatic life, including migratory fish species such as salmon and eel. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in the North Sea coastal zone.
