Overview
Bad SalzuflenHolzhausen wastewater treatment plant serves 6,300 people in Bad Salzuflen, Nordrhein-Westfalen, Germany. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
Bad SalzuflenHolzhausen is a municipal wastewater treatment plant located in the Holzhausen district of Bad Salzuflen, in the Lippe district of Nordrhein-Westfalen, Germany. The plant serves a population of approximately 6,300 residents, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). As a German facility serving fewer than 10,000 people, the plant is required to provide appropriate treatment to meet national and EU standards. The EU directive mandates secondary treatment for all agglomerations above 2,000 population equivalent, with more stringent requirements for sensitive areas. It operates within Germany's robust regulatory framework under the Water Resources Act (Wasserhaushaltsgesetz). The plant's treated effluent is discharged into local watercourses that ultimately drain into the Weser River basin. The Weser flows northward through Lower Saxony to the North Sea, supporting diverse aquatic ecosystems along its course. The plant plays a key role in protecting the local watershed from nutrient pollution and maintaining water quality in the region.
Environmental context
The plant discharges into the local tributary system of the Werre River, which flows into the Weser River near Minden. The Weser is a major German river that drains into the North Sea, supporting important fisheries and migratory fish species such as salmon and eel. The plant's treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the North Sea coastal zone.
