Senden Wastewater Treatment Plant, Nordrhein-Westfalen, Germany

The Senden wastewater treatment plant is located in the town of Senden, within the Kreis Coesfeld district of Nordrhein-Westfalen, Germany. The facility serves a population of approximately 19,379 residents, placing it in the medium agglomeration category under German and EU regulations. As a German plant, Senden operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant is expected to meet these EU standards. The treated effluent from Senden is discharged into local watercourses that ultimately drain into the Rhine River basin. The Rhine is a major European waterway that flows through Germany and the Netherlands into the North Sea. The plant plays a key role in protecting the local aquatic environment and downstream water quality.

Senden lies within the catchment of the Rhine River, one of Europe's most important waterways. The plant's discharge contributes to the Rhine basin, which supports diverse aquatic life and serves as a critical migratory corridor for fish species. The region's agricultural and urban runoff also affect water quality, making the plant's treatment essential for maintaining ecological balance in the local streams and the broader Rhine system.
