TOTES Wastewater Treatment Plant, Vassonville, Normandy, France

TOTES is a wastewater treatment plant located in Vassonville, a commune in the Seine-Maritime department of Normandy, France. The plant serves a population of approximately 2,500 people and is situated along Route de la Scie, near Dieppe. It operates under the French regulatory framework, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 4,600 m³/day and an actual discharge volume of 446 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. As an advanced treatment facility, it meets stringent standards for nutrient removal, particularly important for sensitive receiving environments. The treated effluent is discharged into the local watershed, which ultimately drains into the English Channel via the Scie River and nearby coastal waters. The region's aquatic ecosystems benefit from the plant's advanced treatment, reducing nutrient loads and protecting downstream habitats. The plant plays a key role in maintaining water quality in the Normandy coastal zone.

The plant discharges into the Scie River basin, which flows northward through the Pays de Caux region and empties into the English Channel near Dieppe. The downstream environment includes coastal waters that support diverse marine life, including fish nurseries and migratory bird populations. Advanced treatment helps minimize eutrophication risks in the sensitive coastal zone, protecting both freshwater and marine ecosystems.
