NIEDERBRONN Wastewater Treatment Plant, Reichshoffen, Grand Est, France

The NIEDERBRONN wastewater treatment plant is located in Reichshoffen, within the Bas-Rhin department of the Grand Est region in northeastern France. The facility serves a population of approximately 4,900 people and operates with advanced treatment processes, ensuring high-quality effluent standards. As an advanced treatment plant, NIEDERBRONN goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent requirements under French and EU regulations. The plant has a designed capacity of 12,000 m³/day, with an actual discharge volume of 874.15 m³/day, indicating significant reserve capacity. It operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Rhine River basin. The Rhine is a major European waterway supporting diverse aquatic ecosystems and providing drinking water for millions. The advanced treatment helps protect downstream water quality and biodiversity.

The NIEDERBRONN plant discharges into the local watershed that feeds the Rhine River, one of Europe's most important rivers. The Rhine basin supports a wide range of aquatic life and is a critical migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream ecosystems from eutrophication and maintaining water quality for human and ecological use.
