Oberweis GKA Wastewater Treatment Plant, Oberweis, Rhineland-Palatinate

Oberweis GKA is a municipal wastewater treatment plant located in Oberweis, a municipality in the Eifelkreis Bitburg-Prüm district of Rhineland-Palatinate, Germany. The plant serves a population of approximately 4,500, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The facility is situated in the Prümtal valley, near the Prüm River, a tributary of the Sauer River. As a German plant serving fewer than 10,000 people, Oberweis GKA is subject to the EU UWWTD, which requires secondary treatment for freshwater discharges from agglomerations of this size. Typical facilities in this region employ biological treatment stages to meet German effluent standards, which are among the strictest in Europe under the Wasserhaushaltsgesetz (Water Resources Act). The plant's treated effluent is discharged into the Prüm River, which flows into the Sauer River, then into the Moselle, and ultimately into the Rhine River. The Prüm River supports diverse aquatic life and is part of a network of water bodies in the Eifel region, which is known for its ecological sensitivity and importance for migratory fish species.

Oberweis GKA discharges into the Prüm River, a tributary of the Sauer River, which flows into the Moselle and then the Rhine. The Prüm River supports a variety of fish species and aquatic invertebrates, and its water quality is critical for downstream ecosystems. The Eifel region is characterized by low mountain ranges and forests, with the river providing habitat for species such as brown trout and European bullhead. The plant's operations contribute to maintaining the ecological balance of this watershed.
