Frielendorf _ Verna Wastewater Treatment Plant, Hessen, Germany

Frielendorf _ Verna is a municipal wastewater treatment plant located in the Verna district of Frielendorf, in the Schwalm-Eder-Kreis district of Hessen, Germany. The plant serves a population of around 3,100 people, classifying it as a small agglomeration under EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 3,100 population equivalents, and the plant discharges 784.53 cubic meters of treated wastewater daily. The treated effluent is discharged into local watercourses that ultimately drain into the Schwalm River, a tributary of the Eder, which flows into the Fulda and then the Weser River system. This river network supports diverse aquatic life and is an important ecological corridor in central Germany.

The plant's discharge enters the local watershed, which feeds into the Schwalm River, a tributary of the Eder. The Eder flows into the Fulda, which joins the Weser River, eventually reaching the North Sea. The Schwalm-Eder region is characterized by agricultural land and small settlements, and the water bodies support fish populations and riparian habitats. Secondary treatment helps reduce organic pollution and protect downstream ecosystems.
