Overview
Sainte-Marguerite-sur-Mer wastewater treatment plant in Normandy, France, serves 1,400 people with advanced treatment. It discharges 249.76 m³/day and is located within 10 km of the coast.
The Sainte-Marguerite-sur-Mer wastewater treatment plant is located in the coastal commune of Sainte-Marguerite-sur-Mer in the Normandy region of France. It serves a population of approximately 1,400 residents, typical of a small coastal community. The plant is situated near the English Channel, reflecting the area's maritime character. The facility employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,200 m³/day and a current discharge volume of 249.76 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The advanced treatment likely includes nutrient removal to protect the sensitive coastal environment. The treated effluent is discharged into the English Channel, a vital marine ecosystem. The plant's proximity to the coast (within 10 km) means its discharge must meet stringent standards to prevent eutrophication and protect bathing waters. Normandy's coastline supports diverse marine life and is important for tourism and fisheries.
Environmental context
The plant discharges into the English Channel, a major marine water body that connects to the Atlantic Ocean. The coastal waters of Normandy support rich biodiversity, including fish, shellfish, and seabirds. Advanced treatment helps minimize nutrient loading, which is critical to prevent algal blooms and maintain water quality for recreational use and marine habitats.
