SAINT AUBIN SUR SCIE Wastewater Treatment Plant, Saint-Aubin-sur-Scie, Normandie

SAINT AUBIN SUR SCIE is an advanced wastewater treatment plant located in Saint-Aubin-sur-Scie, a commune in the Seine-Maritime department of Normandie, France. The plant serves a population of 5,400 and has a designed capacity of 15,000 m³ per day, with an actual discharge volume of 963.35 m³ per day. It is situated near the coast, within 10 km of the English Channel. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a French facility, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment levels based on the sensitivity of receiving waters. For coastal discharges, advanced treatment may be mandated to protect marine environments. The treated effluent is discharged into the local watershed, which ultimately drains into the English Channel. The coastal location means the discharge affects a sensitive marine ecosystem that supports diverse aquatic life and is important for regional biodiversity. The plant's advanced treatment helps minimize nutrient loading and protect water quality in the coastal zone.

The plant discharges into the local watershed that drains into the English Channel near Dieppe. The coastal waters in this region support diverse marine life, including fish, crustaceans, and seabirds, and are important for local fisheries and tourism. Advanced treatment reduces nutrient and pollutant loads, helping to protect the sensitive coastal ecosystem from eutrophication and other impacts.
