MEUCON Wastewater Treatment Plant, Meucon, Bretagne, France

MEUCON is a wastewater treatment plant located in Meucon, a commune in the Morbihan department of Bretagne, France. The plant serves a population of 2,246 and is situated near the coast, within 10 km of the Atlantic Ocean. It operates as part of the municipal wastewater infrastructure for the Vannes area. The plant employs advanced treatment processes, ensuring a high level of effluent quality. With a designed capacity of 5,000 m³/day and a current discharge volume of 400.68 m³/day, the plant has ample capacity for future growth. As a French facility, it operates under the national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas. The treated wastewater is discharged into the local watershed, which ultimately drains into the Atlantic Ocean. The plant's proximity to the coast underscores the importance of its advanced treatment in protecting marine water quality and supporting the ecological health of the region's coastal and estuarine environments.

The plant discharges into the local watershed that flows into the Gulf of Morbihan, a semi-enclosed marine basin connected to the Atlantic Ocean. This area supports diverse aquatic life, including seagrass beds and migratory fish species. The advanced treatment helps minimize nutrient loading and protects the sensitive coastal ecosystem from eutrophication.
