Lanmeur Kerocun Wastewater Treatment Plant - Advanced Treatment in Bretagne, France

Lanmeur Kerocun is a wastewater treatment plant located in Lanmeur, a commune in the Finistère department of Bretagne, France. The plant serves a population of approximately 2,019 and has a design capacity of 4,500 cubic meters per day, with an average discharge volume of 360.19 m³/day. It is situated near the coast, within 10 km of the sea. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant operates under French regulations that implement the EU directive, ensuring high effluent quality. The treated wastewater is discharged into the local watershed, which ultimately drains into the English Channel. The coastal environment supports diverse marine life and is important for local fisheries and tourism. The advanced treatment helps minimize nutrient pollution and protects the sensitive coastal ecosystem.

The plant discharges into the coastal waters of the English Channel near Lanmeur. The receiving waters support diverse marine habitats, including rocky shores and estuaries that are important for migratory birds and fish species. The advanced treatment reduces nutrient loading, helping to prevent eutrophication in the coastal zone.
