Bosingen Herrenzimmern Wastewater Treatment Plant | Herrenzimmern, Baden-Württemberg

Bosingen Herrenzimmern is an advanced wastewater treatment plant located in Herrenzimmern, a district of Bösingen in the Rottweil district of Baden-Württemberg, Germany. The plant serves a population of approximately 3,072, placing it in the small agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients such as nitrogen and phosphorus. This level of treatment is typical for plants discharging into sensitive areas or upstream of ecologically important water bodies. The plant has a designed capacity of 2,200 m³/day and currently discharges 777.45 m³/day of treated wastewater. The treated effluent is discharged into a local watercourse that ultimately drains into the Neckar River basin, a major tributary of the Rhine. The Rhine flows through Germany and the Netherlands into the North Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Rhine's diverse fish populations and migratory species.

The plant discharges into a small stream that flows into the Neckar River, a major tributary of the Rhine. The Rhine basin supports diverse aquatic life, including salmon and other migratory fish, and is a critical water resource for millions of people. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in the Rhine and the North Sea.
