Daun GKA Gemunden Wastewater Treatment Plant, Üdersdorf, Rhineland-Palatinate

Daun GKA Gemunden is a municipal wastewater treatment plant located in Üdersdorf, within the Vulkaneifel district of Rhineland-Palatinate, Germany. The plant serves a population of approximately 20,380 people, classifying it as a medium-sized agglomeration under EU regulations. As a German facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet national standards set by the German Water Resources Act (WHG) and the Wastewater Ordinance (AbwV). Treated effluent from the plant is discharged into the local water system, which ultimately drains into the Lieser River, a tributary of the Moselle. The Moselle flows into the Rhine, one of Europe's major rivers, before reaching the North Sea. The plant plays a key role in protecting the Lieser's water quality and the downstream aquatic ecosystems.

The plant discharges into the Lieser River, which flows through the volcanic Eifel region before joining the Moselle. The Moselle then drains into the Rhine, which empties into the North Sea. The Lieser supports diverse aquatic life, including fish species such as brown trout and grayling. The plant's treatment helps maintain water quality in this ecologically sensitive river system.
