Eitorf Wastewater Treatment Plant, Eitorf, Germany | Sieg River Discharge

The Eitorf wastewater treatment plant is located in the town of Eitorf, within the Rhein-Sieg-Kreis district of Nordrhein-Westfalen, Germany. It serves a population of approximately 25,200, 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 discharges to freshwater and estuaries from agglomerations of this scale. The plant's treatment processes and capacity are designed to meet these standards, ensuring compliance with national and EU water quality objectives. The treated effluent is discharged into the Sieg River, a tributary of the Rhine. The Rhine basin is one of Europe's most important waterways, supporting diverse aquatic ecosystems and providing drinking water for millions. The plant plays a key role in protecting the Sieg and Rhine from nutrient pollution and organic loads.

The plant discharges into the Sieg River, which flows into the Rhine River, ultimately reaching the North Sea. The Sieg is a medium-sized river that supports fish populations including salmon and trout, and its water quality is critical for downstream ecosystems. The Rhine basin is ecologically sensitive, with efforts to reduce nutrient loads and improve biodiversity under the EU Water Framework Directive.
