PLEUMEUR BODOU ILE GRANDE Wastewater Treatment Plant, Pleumeur-Bodou, Brittany

PLEUMEUR BODOU ILE GRANDE is an advanced wastewater treatment plant located on the Île Grande in Pleumeur-Bodou, within the Côtes-d'Armor department of Brittany, France. The plant serves a population of 2,520 and has a design capacity of 5,000 m³/day, with an average discharge volume of 449.56 m³/day. 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 EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. For a small agglomeration of this size, advanced treatment is consistent with protecting the local coastal environment. The plant is located within 10 km of the coast, discharging treated wastewater into the surrounding marine environment. The Île Grande is part of the Côtes-d'Armor coastline, which features rocky shores, sandy beaches, and diverse marine habitats. The treated effluent ultimately enters the English Channel, supporting the ecological health of the coastal waters.

The plant discharges into the coastal waters of the English Channel near Île Grande, a tidal island in the Lannion region. The area supports diverse marine life, including seabirds, shellfish, and seagrass beds. The advanced treatment helps minimize nutrient loading and protect the sensitive coastal ecosystem from eutrophication and other pollution impacts.
