Villeneuve-sur-Lot Virebeau Wastewater Treatment Plant, Nouvelle-Aquitaine, France

The Villeneuve-sur-Lot Virebeau wastewater treatment plant is located in the commune of Villeneuve-sur-Lot, in the Lot-et-Garonne department of Nouvelle-Aquitaine, France. The plant serves a population of approximately 34,000, placing it in the medium agglomeration category under French and EU regulations. As a French wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's treatment process and capacity details are not publicly available, but the regulatory framework ensures compliance with national and European standards. The plant's treated effluent is discharged into the Lot River, which flows into the Garonne River, then into the Gironde estuary, and finally into the Atlantic Ocean. This river system supports diverse aquatic life and is important for regional biodiversity. The plant plays a key role in protecting water quality in the Lot watershed and downstream environments.

The plant discharges into the Lot River, a major tributary of the Garonne River. The Garonne flows into the Gironde estuary, the largest estuary in Western Europe, before reaching the Atlantic Ocean. This watershed supports diverse aquatic ecosystems, including migratory fish species such as Atlantic salmon and European eel. The plant's operations help maintain water quality in this ecologically sensitive river system.
