FOULAYRONNES FANGOT Wastewater Treatment Plant, Colayrac-Saint-Cirq, Nouvelle-Aquitaine

FOULAYRONNES FANGOT is an advanced wastewater treatment plant located in Colayrac-Saint-Cirq, near Agen in the Lot-et-Garonne department of Nouvelle-Aquitaine, France. The plant serves a population of approximately 3,500 residents and has a designed capacity of 5,000 cubic meters per day, with a current discharge volume of 624.39 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a French facility, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. Advanced treatment is typically mandated for discharges into sensitive areas or where nutrient removal is necessary to protect water quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Garonne River via the Garonne basin. The Garonne River flows into the Gironde estuary and then the Atlantic Ocean. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the Garonne River and its tributaries.

The plant discharges into the Garonne River basin, which flows through southwestern France into the Gironde estuary and the Atlantic Ocean. The Garonne supports diverse aquatic life, including migratory fish species such as Atlantic salmon and European eel. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality and the ecological balance of the estuary.
