Mittlere Kyll GKA Auw - Advanced Wastewater Treatment Plant in Dahlem, Germany

Mittlere Kyll GKA Auw is a wastewater treatment plant located in Dahlem, within the Bitburger Land region of Rheinland-Pfalz, Germany. The plant serves a population of around 3,576 and has a design capacity of 3,870 cubic meters per day, with a current discharge volume of 700.5 m³/day. As a small to medium agglomeration, it operates under Germany's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients such as nitrogen and phosphorus. This level of treatment is typical for plants discharging into sensitive water bodies or catchments. The plant's capacity utilization indicates room for growth, and its operational status is active based on available data. The treated effluent from Mittlere Kyll GKA Auw is discharged into the local watershed, which is part of the Kyll River basin. The Kyll River flows into the Moselle, a major tributary of the Rhine, ultimately reaching the North Sea. The plant plays a key role in protecting the water quality of the Kyll and downstream ecosystems, supporting aquatic life and recreational uses.

The plant discharges into the Kyll River, a tributary of the Moselle, which flows into the Rhine and eventually the North Sea. The Kyll River supports diverse aquatic life, including fish species such as trout and grayling, and is an important corridor for migratory fish. The advanced treatment at this plant helps reduce nutrient loads, protecting downstream water quality and preventing eutrophication in the Rhine and North Sea.
