The treated effluent from EAUNES is discharged into local watercourses that ultimately flow into the Garonne River, a major river in southwestern France. The Garonne drains into the Gironde estuary and then the Atlantic Ocean. The plant's operation helps protect the ecological health of the Garonne basin, which supports diverse aquatic life and is important for regional water resources.

EAUNES discharges into the Garonne River basin, which flows through Occitanie and Nouvelle-Aquitaine before reaching the Gironde estuary and the Atlantic Ocean.
