Tonisberg Wastewater Treatment Plant, Rheurdt, Nordrhein-Westfalen

Tonisberg is an advanced wastewater treatment plant located in Rheurdt, in the district of Kleve, Nordrhein-Westfalen, Germany. The plant serves a population of approximately 3,700 and is part of the region's municipal wastewater infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 6,400 m³/day and a current discharge volume of 936.38 m³/day, the plant operates well below its capacity, indicating room for future growth. As a German facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas. The treated effluent is discharged into local watercourses that ultimately drain into the Rhine River basin. The Rhine is a major European waterway that flows through Germany into the North Sea, supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's advanced treatment helps protect these downstream environments from nutrient pollution.

Tonisberg's treated effluent enters the local drainage network, which flows into the Rhine River basin. The Rhine is a critical waterway in Europe, supporting diverse aquatic life and providing drinking water for millions. The plant's advanced treatment reduces nutrient loads, helping to prevent eutrophication in downstream waters, including the North Sea. The region's flat terrain and agricultural land use make nutrient management particularly important for local water quality.
