Overview
LA ROCHE POSAY LE BOURG is an advanced wastewater treatment plant in La Roche-Posay, Nouvelle-Aquitaine, France, serving 3,587 people with a design capacity of 7,000 m³/day.
LA ROCHE POSAY LE BOURG is a wastewater treatment plant located in La Roche-Posay, a commune in the Vienne department of Nouvelle-Aquitaine, France. The plant serves a population of 3,587 and has a design capacity of 7,000 m³/day, with an average discharge volume of 639.91 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. This level of treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Creuse River and then the Loire River, flowing into the Atlantic Ocean. The plant plays a key role in protecting the water quality of this river system, supporting aquatic life and downstream uses.
Environmental context
The plant discharges into the Creuse River basin, a tributary of the Loire River, which flows into the Atlantic Ocean. The Loire basin is ecologically significant, supporting diverse aquatic species and migratory fish. Advanced treatment helps reduce nutrient loading, protecting the river from eutrophication and maintaining water quality for downstream ecosystems.
