Overview
LIBOURNE wastewater treatment plant serves the city of Libourne in Nouvelle-Aquitaine, France. It treats wastewater for a population of approximately 46,170 under the EU Urban Waste Water Treatment Directive.
The LIBOURNE wastewater treatment plant is located in Libourne, Gironde, within the Nouvelle-Aquitaine region of southwestern France. The facility serves a population of around 46,170, classifying it as a medium-sized agglomeration under EU regulations. As a French plant, it 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 advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Dordogne River and then the Gironde estuary, a major tidal estuary on the Atlantic coast. This estuary supports diverse aquatic life and is an important ecological corridor for migratory fish species.
Environmental context
The plant discharges into the Dordogne River, which flows into the Gironde estuary, the largest estuary in western Europe. This estuary is a critical habitat for migratory fish like Atlantic salmon and sturgeon, and its waters support extensive fisheries and aquaculture. The region's Atlantic climate and tidal dynamics influence the dispersal and dilution of treated effluent.

The treated effluent is discharged into the local watershed, which flows into the Dordogne River and eventually the Gironde estuary on the Atlantic coast.
As a French plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size and may require tertiary treatment if the receiving waters are sensitive.
Under the EU UWWTD, plants serving between 10,000 and 150,000 population equivalent are required to have secondary treatment. In sensitive areas, additional nutrient removal may be required.
