Urschenheim Wastewater Treatment Plant, Grand Est, France

The Urschenheim wastewater treatment plant is located in the commune of Urschenheim, within the Grand Est region of northeastern France. This facility serves a population of approximately 1,000 residents, reflecting its role as a small-scale municipal treatment operation in the Alsatian countryside. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,100 cubic meters per day and an average daily discharge of 178.40 cubic meters, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local waterways that ultimately drain into the Rhine River basin. The Rhine is a major European waterway flowing through Germany and the Netherlands into the North Sea. The advanced treatment helps protect the sensitive aquatic ecosystems of the Rhine basin, which support diverse fish populations and migratory bird species.

The plant discharges into the local watershed that feeds into the Ill River, a tributary of the Rhine. The Rhine basin is a critical ecological corridor in Europe, supporting numerous fish species such as salmon and eel, and providing habitat for waterfowl. Advanced treatment at this plant helps reduce nutrient loading and protect downstream water quality in the Rhine, which flows through densely populated areas before reaching the North Sea.
