Pulversheim Wastewater Treatment Plant - Grand Est, France

The Pulversheim wastewater treatment plant is located in the commune of Pulversheim, within the Mulhouse urban area in the Haut-Rhin department of Grand Est, France. This facility serves a population of approximately 3,000 residents, placing it in the small agglomeration category under French and EU regulations. 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 4,500 m³/day and an actual discharge volume of 535.19 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. Treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Rhine River via the Ill River system. The Rhine basin is a major European waterway supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's advanced treatment helps protect downstream water quality in this ecologically significant river system.

The plant discharges into the local water network that flows into the Ill River, a tributary of the Rhine River. The Rhine is one of Europe's most important rivers, supporting a rich diversity of fish species and serving as a critical migratory corridor. The advanced treatment at Pulversheim reduces nutrient and pollutant loads, helping to maintain water quality in the Rhine basin, which is subject to the EU Water Framework Directive's objectives for good ecological status.
