SKA Muhringen Horb des AZV Unteres Eyachtal Wastewater Treatment Plant, Felldorf

SKA Muhringen Horb des AZV Unteres Eyachtal is a wastewater treatment plant located in Felldorf, a village in the district of Tübingen, Baden-Württemberg, Germany. The plant serves a population of around 4,650 people and is part of the municipal wastewater infrastructure managed by the AZV Unteres Eyachtal association. As a German plant serving a small agglomeration, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the size of the population served and the sensitivity of the receiving waters. For plants of this scale, secondary treatment is typically mandated, with tertiary treatment required if discharging into sensitive areas. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Neckar River basin. The Neckar flows into the Rhine River, a major European waterway that supports diverse aquatic life and is an important ecological corridor. The plant plays a key role in protecting local water quality and the downstream environment.

The plant discharges into the Neckar River basin, which flows into the Rhine River and eventually the North Sea. The Neckar and Rhine support diverse aquatic ecosystems, including fish species such as salmon and eel, and are important for regional biodiversity. The plant's treatment helps maintain water quality in this ecologically sensitive river system.
