Stapelburg Wastewater Treatment Plant, Landkreis Harz, Germany

Stapelburg wastewater treatment plant is located in the Landkreis Harz district of Sachsen-Anhalt, Germany. The facility serves a population of 2,578 and operates with advanced treatment technology, ensuring high-quality effluent standards. As a plant in Germany, Stapelburg operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum, with tertiary or advanced treatment required in sensitive areas. The plant's designed capacity of 2,800 m³/day indicates it is sized for a small agglomeration, and its current discharge volume of 247.13 m³/day suggests significant reserve capacity. The treated effluent is discharged into local watercourses that eventually drain into the North Sea via the Elbe river system. The plant plays a key role in protecting the region's water quality, supporting aquatic life in the Harz region's streams and rivers.

The plant discharges into the local watershed within the Elbe river basin, which flows northward through Germany to the North Sea. The Harz region features sensitive ecosystems, including streams that support diverse aquatic life. Advanced treatment helps minimize nutrient and pollutant loads, protecting downstream water quality in the Elbe estuary and the Wadden Sea, an ecologically important coastal zone.
