Overview
MUZILLAC le borec is an advanced wastewater treatment plant in Muzillac, Brittany, France, serving 3,850 people. It discharges treated effluent near the coast, with a design capacity of 7,200 m³/day.
MUZILLAC le borec is a municipal wastewater treatment plant located in Muzillac, a commune in the Morbihan department of Brittany, northwestern France. The plant serves a population of approximately 3,850 people, placing it in the small agglomeration category under French and EU regulations. The facility employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a design capacity of 7,200 m³/day and an average discharge volume of 686.83 m³/day, the plant operates well within its capacity, ensuring effective treatment of incoming wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Gulf of Morbihan or nearby coastal waters. The plant's proximity to the coast (within 10 km) means its discharge must meet stringent standards to protect sensitive marine and estuarine ecosystems, including those supporting diverse aquatic life and migratory species.
Environmental context
The plant discharges into the coastal watershed of southern Brittany, with the treated effluent flowing into the Gulf of Morbihan, a semi-enclosed marine inlet connected to the Atlantic Ocean. This area supports diverse marine habitats, including seagrass beds and nursery grounds for fish, and is an important migratory corridor for birds. The advanced treatment level helps minimize nutrient loading and protect water quality in this ecologically sensitive coastal zone.
