Hamersleben Wastewater Treatment Plant, Am Großen Bruch, Germany

Hamersleben wastewater treatment plant is located in the village of Hamersleben, part of the municipality Am Großen Bruch in the Börde district of Sachsen-Anhalt, Germany. The plant serves a population of 2,698 and has a designed capacity of 3,000 m³/day, with an average discharge volume of 262.29 m³/day. 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 agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The treated effluent is discharged into local watercourses that drain into the Aller river system, which flows northward to the Weser and eventually into the North Sea. The surrounding region is agricultural, and the plant's advanced treatment helps reduce nutrient loading to downstream ecosystems.

The plant discharges into small streams in the Aller river basin, which flows into the Weser and then the North Sea. The region is part of the Elbe-Weser drainage area, supporting agricultural landscapes and diverse aquatic habitats. Advanced treatment reduces nutrient pollution, protecting downstream waters from eutrophication and maintaining water quality for fish and invertebrates.
