Gerolstein GKA Lissingen Wastewater Treatment Plant, Gerolstein, Germany

Gerolstein GKA Lissingen is a municipal wastewater treatment plant located in the Lissingen district of Gerolstein, in the Vulkaneifel region of Rhineland-Palatinate, Germany. The plant serves a population of around 18,635, classifying it as a medium-sized agglomeration under EU regulations. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's treatment process and capacity details are not publicly available, but it is expected to meet the regulatory standards for its population tier. The plant discharges treated wastewater into a local watercourse that eventually drains into the Kyll River, a tributary of the Moselle, which flows into the Rhine and ultimately the North Sea. The Vulkaneifel region is known for its volcanic landscapes and ecologically sensitive streams, making proper wastewater treatment essential for protecting aquatic habitats and downstream water quality.

The plant's treated effluent enters a small stream that feeds into the Kyll River, a tributary of the Moselle, which joins the Rhine and flows to the North Sea. The Vulkaneifel region features numerous small watercourses that support diverse aquatic life, including fish and macroinvertebrates. The area is also part of a volcanic landscape with groundwater-dependent ecosystems, so maintaining high water quality is critical for ecological health.
