Alsfeld Hattendorf Wastewater Treatment Plant, Hattendorf, Hessen, Germany

The Alsfeld Hattendorf wastewater treatment plant is located in the Hattendorf district of Alsfeld, in the state of Hessen, Germany. It served a small population of approximately 736 residents before its closure. The plant was designed with a capacity of 2000 cubic meters per day and treated an average discharge volume of 186.26 cubic meters per day. The plant provided advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal to protect sensitive water bodies. The plant's operational status is now closed, and its infrastructure may be decommissioned or repurposed. It is located inland in the Vogelsbergkreis region, which drains into the Fulda River system, a tributary of the Weser River. The Weser flows into the North Sea, making the plant part of the Weser basin. The advanced treatment level would have helped protect downstream aquatic ecosystems from nutrient pollution.

The plant is situated in the Weser River basin, with its treated effluent likely discharging into local streams that feed the Fulda River, a major tributary of the Weser. The Weser flows through central Germany into the North Sea, supporting diverse aquatic life and important migratory fish species. The advanced treatment level would have reduced nutrient loads, helping to prevent eutrophication in downstream waters.
