VIVONNE is an advanced wastewater treatment plant located in Château-Larcher, within the Nouvelle-Aquitaine region of France. The facility serves a population of approximately 3,700, providing essential sanitation services to this small community in the Vienne department. The plant is situated inland, away from coastal areas, and plays a key role in managing local wastewater. As an advanced treatment facility, VIVONNE goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. The plant has a designed capacity of 7,000 cubic meters per day and currently discharges around 660 cubic meters daily, indicating ample reserve capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size are required to provide secondary treatment, but VIVONNE exceeds these standards with advanced processes. The treated effluent from VIVONNE is discharged into the local watershed, which ultimately drains into the Vienne River and then the Loire River, one of France's major waterways. This contributes to the protection of downstream aquatic ecosystems and supports biodiversity in the Loire basin. The plant's advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in sensitive water bodies.
Environmental context
VIVONNE discharges into the local river system that feeds into the Vienne River, a tributary of the Loire River. The Loire basin is ecologically significant, supporting diverse aquatic life and migratory fish species. The plant's advanced treatment helps minimize nutrient pollution, protecting downstream water quality and the ecological health of the Loire estuary.
