The Billiers wastewater treatment plant is located in the commune of Billiers, in the Morbihan department of Brittany, France. It serves a population of 919 residents and is situated near the coast, reflecting the region's coastal and rural character. As an advanced treatment facility, Billiers goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent French and European standards. The plant has a designed capacity of 3,500 cubic meters per day, indicating ample capacity for current and future needs. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), such advanced treatment is typical for sensitive areas, which coastal zones often are. The treated effluent is discharged into the local environment, likely into the Vilaine River estuary or directly into the Bay of Biscay, given the plant's proximity to the coast. This discharge supports the ecological health of the downstream waters, which are important for marine life and migratory birds.
Environmental context
The plant discharges into the coastal waters of the Bay of Biscay, part of the Atlantic Ocean. The receiving environment includes the Vilaine River estuary, a nutrient-rich area that supports diverse aquatic life, including fish nurseries and migratory bird populations. Advanced treatment helps minimize eutrophication risks in these sensitive coastal ecosystems.
