The coastal environment supports diverse marine life and is important for local fisheries and tourism. Proper treatment is essential to prevent nutrient pollution and protect the ecological health of the Bay of Biscay.

The plant is situated near the Atlantic coast in the Vendée region, with treated effluent likely discharging into the Vie River or directly into coastal waters. The receiving environment includes the Bay of Biscay, a productive marine ecosystem that supports commercial fisheries and migratory bird populations. Protecting this coastal zone from nutrient enrichment and pathogens is critical for maintaining water quality and biodiversity.
