As a secondary treatment plant, MONTUSSAN 2 provides biological treatment to reduce organic matter and suspended solids before discharge. The plant has a designed capacity of 3,500 cubic meters per day and currently treats an average daily flow of approximately 482 cubic meters, indicating ample reserve capacity. The facility is part of the wastewater infrastructure managed by the Bordeaux metropolitan area. The treated effluent from MONTUSSAN 2 is discharged into the local water system, which flows into the Garonne River via smaller tributaries.

This watershed supports diverse aquatic life and is important for regional agriculture and recreation.
Environmental context
The plant discharges into the local drainage network that feeds the Garonne River, a major river in southwestern France. The Garonne flows through Bordeaux and into the Gironde estuary, a large estuary that supports diverse fish species including migratory sturgeon and salmon. The downstream environment is ecologically sensitive, with wetlands and tidal flats that provide critical habitat for birds and aquatic organisms. The Atlantic Ocean receives the final discharge, making nutrient and pollutant control important for coastal water quality.
