Overview
ANGERVILLE wastewater treatment plant in Le Mérévillois, Centre-Val de Loire, France, serves approximately 4,775 people with secondary treatment and a designed capacity of 6,000 m³/day.
The ANGERVILLE wastewater treatment plant is located in Le Mérévillois, within the Centre-Val de Loire region of France. It serves a population of approximately 4,775 people, classifying it as a small agglomeration under French and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 6,000 m³/day, with a reported discharge volume of 851.85 m³/day, indicating operational capacity well within design limits. As a French facility, it operates under national regulations transposing the EU directive, with permits issued by the relevant prefecture or water agency. The treated effluent is discharged into a local watercourse, likely a tributary of the Seine River basin, which ultimately flows into the English Channel. The plant plays a key role in protecting the local watershed from nutrient pollution and organic load, supporting the ecological health of downstream rivers and the Seine estuary.
Environmental context
The plant discharges into a local watercourse within the Seine River basin, which flows through the Paris region and into the Seine estuary before reaching the English Channel. The downstream environment includes sensitive aquatic habitats that benefit from nutrient removal provided by secondary treatment. The plant's location inland reduces direct marine impact, but its effluent contributes to the overall water quality of the Seine basin, which supports diverse freshwater and estuarine ecosystems.
