Overview
Bordeaux Eysines Cantinolles 2 is a large wastewater treatment plant in Eysines, Nouvelle-Aquitaine, France, serving over 150,000 people. It operates under the EU Urban Waste Water Treatment Directive.
Bordeaux Eysines Cantinolles 2 is a major wastewater treatment facility located in Eysines, a commune in the Bordeaux metropolitan area of Nouvelle-Aquitaine, France. The plant serves a population of approximately 154,251, classifying it as a large agglomeration under EU regulations. As a plant serving over 150,000 people, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment (tertiary) for discharges into sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a substantial infrastructure to handle the region's wastewater. The treated effluent from the plant ultimately drains into the Garonne River via local waterways, flowing into the Gironde estuary and then the Atlantic Ocean. This discharge contributes to the ecological health of the estuary, which supports diverse aquatic life and is an important migratory corridor for fish species.
Environmental context
The plant discharges into the Garonne River watershed, which flows into the Gironde estuary, a major European estuary that empties into the Bay of Biscay (Atlantic Ocean). The estuary supports diverse aquatic life, including migratory fish such as salmon and eels, and is ecologically sensitive due to its role as a nursery for marine species.
