Moers Gerdt Wastewater Treatment Plant, Duisburg, Nordrhein-Westfalen

Moers Gerdt is a wastewater treatment plant located in Duisburg, in the state of Nordrhein-Westfalen, Germany. The facility serves a population of around 190,000, classifying it as a large agglomeration under EU regulations. Its location near the Rhine River places it within a densely populated and industrially active region. As a German plant serving over 150,000 people, Moers Gerdt is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates tertiary treatment for discharges into sensitive areas. The Rhine basin is designated as sensitive under the directive, requiring advanced nutrient removal to protect water quality. The plant's treatment processes are designed to meet these stringent standards. The treated effluent from Moers Gerdt ultimately discharges into the Rhine River, one of Europe's major waterways. The Rhine flows through Germany and the Netherlands before reaching the North Sea, supporting diverse aquatic ecosystems and serving as a critical drinking water source. The plant plays a key role in maintaining the ecological health of this transboundary river system.

The plant discharges into the Rhine River, which flows through Germany and the Netherlands into the North Sea. The Rhine basin supports diverse aquatic life, including migratory fish species such as salmon and eel. Nutrient and pollutant loads from urban and industrial sources are managed under the EU Water Framework Directive to protect downstream ecosystems and drinking water supplies.
