Halle Horste Wastewater Treatment Plant, Halle (Westf.) | Closed Advanced Facility

Halle Horste is a former wastewater treatment plant located in the Hörste district of Halle (Westf.), in the Kreis Gütersloh region of Nordrhein-Westfalen, Germany. The plant was designed to serve a small population of 1,227 people, with a designed capacity of 2,500 cubic meters per day. It operated with advanced treatment processes before being closed. As a German plant serving a small agglomeration, it would have been subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for all discharges and more stringent treatment in sensitive areas. The advanced treatment level indicates that the plant likely employed nutrient removal or other tertiary processes to meet local water quality standards. The plant's discharge volume of 310.52 m³/day was directed to local water bodies in the Weser river basin. The Weser flows northward through Germany, eventually reaching the North Sea. The plant's operations would have helped protect the ecological health of the receiving waters, supporting aquatic life and downstream water quality.

The plant discharged into the Weser river basin, which drains into the North Sea. The Weser is an important river system in northern Germany, supporting diverse aquatic ecosystems and providing habitat for fish species such as salmon and sea trout. The advanced treatment at Halle Horste helped reduce nutrient loads, protecting downstream water quality in the Weser and its tributaries.
