Rosendahl Holtwick Wastewater Treatment Plant - Rosendahl, Nordrhein-Westfalen, Germany

Rosendahl Holtwick is a wastewater treatment plant located in the Holtwick district of Rosendahl, in the Kreis Coesfeld region of Nordrhein-Westfalen, Germany. The plant serves a population of approximately 7,182 people, classifying it as a small to medium 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 agglomerations with a population equivalent (PE) between 2,000 and 10,000 in freshwater areas. The directive ensures that treated effluent meets quality standards to protect receiving waters. The plant discharges into the local watershed, which is part of the Rhine basin. The treated water ultimately flows into the Rhine River and then to the North Sea. This region supports diverse aquatic life and is important for migratory fish species, making proper treatment essential for ecological health.

The plant's treated effluent enters the local drainage network, which flows into the Rhine River basin. The Rhine is a major European waterway that supports diverse aquatic ecosystems and provides drinking water for millions. Downstream, the river discharges into the North Sea, a sensitive marine environment. Proper wastewater treatment is critical to prevent nutrient pollution and protect both freshwater and coastal habitats.
