ELVEN Kerlore is an advanced wastewater treatment plant located in Elven, within the Morbihan department of Bretagne, France. The facility serves a population of approximately 5,010 people and has a designed capacity of 10,000 m³/day, with an average daily discharge of 893.77 m³/day. As an advanced treatment plant, ELVEN Kerlore goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent French and EU standards. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations between 2,000 and 10,000 population equivalent are required to provide secondary treatment, and advanced treatment is mandated in sensitive areas. The plant's advanced level indicates it likely operates in a sensitive catchment or discharges to a vulnerable water body. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Gulf of Morbihan, a semi-enclosed marine inlet on the Atlantic coast. The Gulf of Morbihan is an ecologically significant area supporting diverse marine life, including seagrass beds and migratory birds. The plant's advanced treatment helps protect this sensitive coastal environment from nutrient enrichment and pollution.
Environmental context
The plant discharges into the local river system that flows into the Gulf of Morbihan, a semi-enclosed marine inlet on the Atlantic coast of Brittany. The Gulf is an ecologically sensitive area with extensive seagrass meadows, salt marshes, and mudflats that support diverse aquatic life, including fish nurseries and migratory bird populations. Advanced treatment at ELVEN Kerlore helps minimize nutrient and pollutant loads, protecting the Gulf's water quality and biodiversity.
