SAINT LYPHARD 1 Belle Fontaine is a municipal wastewater treatment plant located in Saint-Lyphard, a commune in the Loire-Atlantique department of Pays de la Loire, France. The plant serves a population of approximately 2,717 and has a design capacity of 5,200 m³/day, with a reported discharge volume of 484.71 m³/day. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size (2,000-10,000 population equivalent) are required to have secondary treatment, which this plant meets. The plant is located within 10 km of the coast, indicating its discharge may impact sensitive coastal waters. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Loire estuary or nearby coastal areas. The region supports diverse aquatic life and is an important area for migratory birds and marine species. Proper treatment helps protect the ecological health of the downstream environment.
Environmental context
The plant discharges into the local watershed near the Atlantic coast of Pays de la Loire. The receiving waters flow into the Bay of Biscay, a productive marine ecosystem that supports fisheries and marine biodiversity. The coastal zone includes ecologically sensitive habitats such as salt marshes and estuaries, which rely on good water quality to sustain aquatic life and migratory bird populations.
