ST ALBAN SUR LIMAGNOLE Wastewater Treatment Plant, Saint-Alban-sur-Limagnole, Occitanie

ST ALBAN SUR LIMAGNOLE is a wastewater treatment plant located in Saint-Alban-sur-Limagnole, a commune in the Lozère department of Occitanie, southern France. The plant serves a population of 2,511 and has a designed capacity of 2,700 m³/day, with an average discharge volume of 447.96 m³/day. 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 receiving waters. The plant operates under French regulations implementing the directive, overseen by the local water agency. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Truyère River and the Lot River system. The plant plays a key role in protecting the water quality of the region's rivers and supporting the ecological health of the downstream environment.

The plant discharges into the Limagnole River, a tributary of the Truyère, which flows into the Lot River and eventually reaches the Garonne and the Atlantic Ocean. The watershed supports diverse aquatic life and is part of a region known for its natural landscapes. Advanced treatment helps minimize nutrient pollution, protecting downstream ecosystems from eutrophication.
