KA Crottendorf Wastewater Treatment Plant, Crottendorf, Saxony, Germany

KA Crottendorf is a municipal wastewater treatment plant located in Crottendorf, in the Erzgebirgskreis district of Saxony, Germany. The plant serves a population of about 4,700 and operates with an advanced treatment level, ensuring high-quality effluent standards. The plant's designed capacity is 4,800 m³/day, and it currently treats 626.70 m³/day of wastewater. As a German facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and agglomerations of this scale. The plant's advanced treatment likely includes nutrient removal to protect receiving waters. The treated effluent is discharged into local watercourses that drain into the Zschopau River, a tributary of the Mulde River, which eventually flows into the Elbe River and the North Sea. The plant plays a key role in protecting the water quality of the Erzgebirge region's streams and downstream ecosystems.

KA Crottendorf discharges into local streams that feed the Zschopau River, part of the Mulde-Elbe river system flowing to the North Sea. The Erzgebirge region is ecologically sensitive, supporting diverse aquatic life and serving as a water source for downstream communities. Advanced treatment helps minimize nutrient loading and protects the riverine habitat.
