FOUILLOUSE LA Moulin Saint Paul Wastewater Treatment Plant, La Fouillouse, France

FOUILLOUSE LA Moulin Saint Paul is a wastewater treatment plant located in La Fouillouse, a commune in the Loire department of the Auvergne-Rhône-Alpes region, France. The plant serves a population of approximately 4,442 people and is part of the region's municipal wastewater infrastructure. 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. With a designed capacity of 5,850 m³/day and a current discharge volume of 792.44 m³/day, the facility operates well within its capacity, ensuring effective treatment of wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River, one of France's major rivers. The Loire River supports diverse aquatic ecosystems and is an important ecological corridor. The plant's advanced treatment helps protect downstream water quality and the sensitive environments along the Loire basin.

The plant discharges into the local watershed that feeds the Loire River, which flows through central France before reaching the Atlantic Ocean. The Loire basin is ecologically significant, supporting diverse aquatic life and serving as a migratory route for fish species. Advanced treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream habitats and water quality.
