CLISSON 1 La Batardiere is a municipal wastewater treatment plant located in Gorges, within the Pays de la Loire region of western France. The facility serves a population of approximately 9,933 people, placing it in the medium agglomeration category under European Union regulations. As a French plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000 discharging into freshwater. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Loire River and then into the Bay of Biscay. The Loire basin supports diverse aquatic life and is an important ecological corridor in western France. Proper treatment helps protect downstream water quality and the marine environment.
Environmental context
The plant discharges into the Loire River basin, which flows through the Pays de la Loire region before reaching the Bay of Biscay on the Atlantic coast. The Loire is one of France's major rivers, supporting diverse aquatic ecosystems and serving as a critical habitat for migratory fish species. The downstream estuary is ecologically sensitive, with extensive wetlands and mudflats that provide important feeding and breeding grounds for birds.
