POUILLY LES FEURS Bourg Wastewater Treatment Plant, Pouilly-lès-Feurs, France

POUILLY LES FEURS Bourg is a wastewater treatment facility located in the commune of Pouilly-lès-Feurs, within the Loire department of the Auvergne-Rhône-Alpes region in central France. The plant serves a population of about 5,144 residents, placing it in the small-to-medium agglomeration category under French regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 2,200 m³/day, with an average daily discharge volume of approximately 918 m³. The facility is operated as part of the municipal wastewater infrastructure managed by local authorities. Treated effluent from the plant is discharged into local watercourses that ultimately drain into the Loire River basin. The Loire is France's longest river and flows into the Atlantic Ocean, supporting diverse aquatic ecosystems. The plant's advanced treatment helps protect downstream water quality in this ecologically significant watershed.

The plant discharges into the Loire River basin, which flows westward through central France before emptying into the Bay of Biscay (Atlantic Ocean). The Loire is known for its biodiversity, including migratory fish species such as Atlantic salmon and European eel. The advanced treatment level helps reduce nutrient loading and protect the river's ecological health, particularly in the context of the EU Water Framework Directive's goals for good chemical and ecological status.
