Baunatal _ Guntershausen Wastewater Treatment Plant, Baunatal, Hessen, Germany

Baunatal _ Guntershausen is a former wastewater treatment plant located in the Guntershausen district of Baunatal, in the Landkreis Kassel, Hessen, Germany. The plant served a small population of 1,600 people and was designed with a capacity of 2,000 m³ per day. It is now closed. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent (PE) between 2,000 and 10,000, and Baunatal _ Guntershausen, serving 1,600 people, falls below this threshold, though it still met secondary treatment standards. The plant's treated effluent was discharged into local water bodies within the Fulda River basin, which flows into the Weser River and ultimately to the North Sea. The closure of the plant suggests that wastewater from this area is now treated at a larger regional facility, improving overall treatment efficiency and environmental protection.

The plant discharged into the Fulda River catchment, part of the Weser River basin that drains into the North Sea. The Weser basin supports diverse aquatic life and is an important migratory corridor for fish species. The region's water quality is regulated under the EU Water Framework Directive, aiming for good ecological status.
