Ratingen Hosel Dickelsbach Wastewater Treatment Plant, Ratingen, Germany

Ratingen Hosel Dickelsbach is an advanced wastewater treatment plant located in the Hösel district of Ratingen, in the state of Nordrhein-Westfalen, Germany. The plant serves a population of approximately 2,327 residents and is part of the municipal wastewater infrastructure for the area. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants discharging into sensitive water bodies under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant has a designed capacity of 5,000 m³/day and currently treats an average daily flow of 837.82 m³/day. The treated effluent is discharged into local watercourses that eventually 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 downstream water quality and ecological health.

The plant discharges into the local drainage network that feeds into the Rhine River, which flows through Germany and the Netherlands before reaching the North Sea. The Rhine basin supports a wide range of aquatic life, including migratory fish species, and is an important water resource for agriculture and industry. Advanced treatment at this plant helps reduce nutrient loading, which is critical for preventing eutrophication in downstream lakes and coastal zones.
