Huenxe Wastewater Treatment Plant, Krudenburg, Nordrhein-Westfalen, Germany

The Huenxe wastewater treatment plant is located in Krudenburg, a district of Hünxe in the Wesel district of Nordrhein-Westfalen, Germany. It serves a population of approximately 11,884, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant is situated near the Rhine River, a major European waterway, and operates within Germany's stringent national water protection framework. Under the EU UWWTD, agglomerations with a population equivalent (PE) between 10,000 and 100,000 are required to provide secondary treatment as a minimum. For plants in sensitive areas, such as those discharging into the Rhine basin, tertiary treatment for nutrient removal is often mandated. It is expected to comply with these regulatory standards. The treated effluent from the Huenxe plant is discharged into the local water system, which ultimately drains into the Rhine River. The Rhine is a critical waterway for Europe, supporting diverse aquatic life and serving as a major source of drinking water for millions. The plant's operations contribute to protecting the Rhine's water quality by reducing pollutant loads from the surrounding urban and industrial areas.

The Huenxe plant discharges into the local water network that flows into the Rhine River, one of Europe's most important waterways. The Rhine basin supports a rich ecosystem, including migratory fish species such as salmon and eel, and provides drinking water for over 20 million people. The plant's location in the Lower Rhine region, a densely populated and industrialized area, underscores its role in maintaining water quality and preventing eutrophication in downstream lakes and the North Sea.
