BORDEAUX SABAREGES 2 is a municipal wastewater treatment plant located in Ambarès-et-Lagrave, a commune in the Bordeaux metropolitan area of Nouvelle-Aquitaine, France. The plant serves a population of approximately 124,271, classifying it as a large agglomeration under EU regulations. As a facility of this scale in France, the plant is expected to provide at least secondary treatment in compliance with the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations over 100,000 population equivalent, the directive mandates secondary treatment as a minimum, with tertiary treatment required if the receiving waters are designated as sensitive areas. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Garonne River and then the Gironde estuary, a major ecological corridor on the Atlantic coast. The estuary supports diverse aquatic life and is an important migratory route for fish species.
Environmental context
The plant discharges into the Garonne River basin, which flows into the Gironde estuary, the largest estuary in Western Europe. This estuary is a critical habitat for migratory fish such as salmon and eels, and supports a rich diversity of birdlife. The watershed is influenced by tidal dynamics and agricultural runoff, making nutrient management important for water quality.
