DUPPIGHEIM Wastewater Treatment Plant, Hangenbieten, Grand Est, France

The DUPPIGHEIM wastewater treatment plant is located in Hangenbieten, a commune in the Bas-Rhin department of the Grand Est region, France. It serves a population of about 19,000, placing it in the medium agglomeration category under French regulations. The plant is situated near the Canal de la Bruche and the Bruche River, which are part of the broader Rhine basin. As a French facility, the plant 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 stringent treatment if the receiving waters are designated as sensitive areas. It is expected to comply with national standards for effluent quality. The treated wastewater is discharged into the local water system, likely the Bruche River, which flows into the Ill River and eventually the Rhine. The Rhine is a major European waterway that supports diverse aquatic life and is an important ecological corridor. The plant's operations help protect the water quality of these rivers and the downstream environment.

The plant discharges into the Bruche River, a tributary of the Ill River, which joins the Rhine River. The Rhine basin is a vital ecological corridor supporting diverse fish species and migratory birds. The area is part of the Alsace floodplain, which includes sensitive wetlands and alluvial forests that depend on clean water. Proper treatment helps maintain the ecological balance of these downstream habitats.
