Benndorf Grobers Wastewater Treatment Plant, Benndorf, Saxony-Anhalt

Benndorf Grobers is a wastewater treatment plant located in Benndorf, a district of Kabelsketal in the Saalekreis region of Saxony-Anhalt, Germany. The plant serves a population of around 4,939 and has a designed capacity of 10,000 m³/day, indicating it is sized for a moderate agglomeration. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. As an advanced treatment facility, Benndorf Grobers likely employs processes such as nutrient removal (nitrogen and phosphorus) to meet stringent effluent standards. The plant operates under Germany's national implementation of the EU Urban Waste Water Treatment Directive, which mandates advanced treatment for sensitive areas. The actual discharge volume is 642.95 m³/day, well below the designed capacity, suggesting room for future growth or seasonal variations. The treated effluent from Benndorf Grobers is discharged into local watercourses that ultimately drain into the Saale River, a major tributary of the Elbe River. The Elbe flows through Germany into the North Sea. The plant plays a key role in protecting the Saale and Elbe river basins from nutrient pollution, supporting aquatic life and downstream water quality.

Benndorf Grobers discharges into the Saale River basin, which flows into the Elbe River and eventually the North Sea. The region is part of the Elbe catchment, an ecologically important area that supports diverse aquatic habitats and migratory fish species. Advanced treatment at this plant helps reduce nutrient loads, mitigating eutrophication risks in the downstream Elbe estuary and North Sea coastal waters.
