Lichtenfels _ Sachsenberg Wastewater Treatment Plant, Hessen, Germany

The Lichtenfels _ Sachsenberg wastewater treatment plant is located in Sachsenberg, a district of Lichtenfels in the Landkreis Waldeck-Frankenberg, Hessen, Germany. It served a population of 1,269 people, classifying it as a small agglomeration under German and EU regulations. The plant is currently closed. The facility provided advanced treatment, which goes beyond the secondary treatment standard 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 had a designed capacity of 2,250 cubic meters per day, with an average discharge volume of 321.15 cubic meters per day. The treated effluent was discharged into the local watershed, which ultimately drains into the Eder River, a tributary of the Fulda River, which flows into the Weser River and then to the North Sea. The plant's advanced treatment helped protect the aquatic ecosystem of the Eder and downstream waters from nutrient pollution.

The plant discharged into the Eder River basin, which flows through the Kellerwald-Edersee region, an area known for its diverse aquatic life and migratory fish species. The Eder River joins the Fulda River, which feeds into the Weser River, ultimately reaching the North Sea. Advanced treatment at this plant helped reduce nutrient loads, supporting the ecological health of downstream waters.
