Typical facilities of this scale in the region employ biological treatment with activated sludge or similar processes. The plant discharges treated effluent into the Garonne River, which flows through the Gironde estuary and into the Bay of Biscay (Atlantic Ocean). The Garonne is a major river in southwestern France, supporting diverse aquatic life and providing water for agriculture and drinking water downstream. The plant plays a key role in protecting the river's water quality and the ecological health of the estuary.

The Garonne is a major river supporting diverse aquatic species and is an important migratory corridor for fish such as salmon and eels. The estuary is ecologically sensitive, with extensive mudflats and marshes that provide habitat for birds and marine life. Protecting water quality in this system is critical for both ecological health and human uses like fishing and recreation.
