Meinerzhagen Wastewater Treatment Plant: Serving Meinerzhagen, Nordrhein-Westfalen

The Meinerzhagen wastewater treatment plant is located in the town of Meinerzhagen, in the Märkischer Kreis district of Nordrhein-Westfalen, Germany. The plant serves a population of approximately 17,900, classifying it as a medium-sized agglomeration under EU regulations. As a German wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent above 2,000. For populations between 10,000 and 150,000, the directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Rhine River basin. The Rhine is one of Europe's major rivers, flowing through multiple countries before reaching the North Sea. The plant plays a key role in protecting the water quality of these downstream ecosystems.

The plant discharges into local streams that feed into the Volme River, a tributary of the Ruhr River, which ultimately flows into the Rhine. The Rhine basin supports diverse aquatic life and is an important migratory corridor for fish species. The plant's treatment processes help reduce nutrient and pollutant loads, protecting downstream water quality in this densely populated and industrialized region.
