Overview
Rollsdorf wastewater treatment plant serves approximately 50,000 people in Salzatal, Saxony-Anhalt, Germany. It operates under the EU Urban Waste Water Treatment Directive, ensuring compliance with secondary treatment standards.
Rollsdorf wastewater treatment plant is located in the Höhnstedt district of Salzatal, within the Saalekreis district of Saxony-Anhalt, Germany. The facility serves a population of approximately 50,118, classifying it as a medium-to-large agglomeration under EU regulations. As a German plant, Rollsdorf is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet these standards, ensuring effective removal of organic matter and nutrients before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Saale River, a major tributary of the Elbe River. The Elbe flows into the North Sea, making the plant's operations important for downstream water quality and the ecological health of the Elbe estuary.
Environmental context
The plant's discharge enters the Saale River basin, which flows northward to join the Elbe River near Barby. The Elbe then continues to the North Sea, supporting diverse aquatic life and important migratory fish species such as Atlantic salmon and sea trout. The watershed includes agricultural and urban areas, making nutrient management critical to prevent eutrophication in downstream waters.
