FELDKIRCH is an advanced wastewater treatment plant located in Colmar, within the Grand Est region of France. The facility serves a population of approximately 3,600 people, making it a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated near the D 4 road in the Haut-Rhin department, part of the historic Alsace region. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. Its designed capacity is 5,500 m³/day, and it currently discharges an average of 642.23 m³/day of treated wastewater. As a French facility, it operates under national regulations that implement the EU UWWTD, ensuring compliance with stringent effluent quality standards. The treated effluent from FELDKIRCH is discharged into the local watershed, which ultimately drains 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's advanced treatment helps protect the sensitive aquatic ecosystems of the Rhine basin, including important fish spawning grounds and migratory corridors for species such as salmon and eel.
Environmental context
FELDKIRCH discharges treated wastewater into the local watershed, which feeds into the Rhine River basin. The Rhine flows northward through Germany and the Netherlands, eventually reaching the North Sea. This basin supports diverse aquatic life and is an important migratory corridor for fish species. The plant's advanced treatment helps reduce nutrient loads and pollutants, contributing to the ecological health of the downstream environment.
