ANCERVILLE Wastewater Treatment Plant, Saint-Dizier, Grand Est, France

The ANCERVILLE wastewater treatment plant is located in Saint-Dizier, within the Grand Est region of France. It serves a population of approximately 1,972 people, placing it in the small agglomeration category under French regulations. The plant is situated inland, away from coastal areas, and its operations are part of the municipal wastewater infrastructure for the local community. 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 5,000 m³/day and a current discharge volume of 351.80 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The advanced treatment level ensures high-quality effluent suitable for discharge into sensitive environments. The treated effluent is discharged into local water bodies that ultimately drain into the Seine River basin, which flows through the Paris region and into the English Channel. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Seine's diverse fish populations and the estuarine environment near the coast. By meeting stringent EU standards, the facility contributes to the ecological health of the regional watershed.

The plant discharges into local waterways that are part of the Seine River basin, which flows northward through the Grand Est and Île-de-France regions before reaching the English Channel. The Seine supports diverse aquatic life, including migratory fish species such as salmon and eel. The advanced treatment at ANCERVILLE helps reduce nutrient loads and pollutants, protecting downstream water quality and the sensitive estuarine habitats near the coast.
