Borgentreich Alstertal Wastewater Treatment Plant | Advanced Treatment in Nordrhein-Westfalen

Borgentreich Alstertal is a wastewater treatment plant located in Borgentreich, a town in the Kreis Höxter district of Nordrhein-Westfalen, Germany. The plant serves a population of approximately 2,495 people, 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 the secondary treatment standard required by the EU UWWTD for agglomerations of this size. With a designed capacity of 3,513 m³/day and a reported discharge volume of 768 m³/day, the plant has significant reserve capacity. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The treated effluent is discharged into local watercourses that ultimately drain into the Weser River basin. The Weser flows northward through Germany to the North Sea. The plant's advanced treatment helps maintain water quality in the region, supporting aquatic life and downstream ecosystems in the Weser catchment.

The plant discharges into local streams that are part of the Weser River basin. The Weser flows through central Germany to the North Sea, supporting diverse aquatic habitats and serving as an important migratory corridor for fish. The region's agricultural land use makes nutrient removal critical to prevent eutrophication in downstream waters.
