The treated effluent is discharged into local watercourses that ultimately feed into the Gave de Pau river, a major tributary of the Adour river system, which flows into the Atlantic Ocean. The plant plays a crucial role in protecting the pristine mountain streams and downstream aquatic ecosystems from pollution.
Environmental context
The plant discharges into the Gave de Pau river basin, which flows through the Pyrenees and eventually joins the Adour river before reaching the Bay of Biscay. This watershed supports diverse aquatic life, including salmonid populations, and is ecologically sensitive due to its mountainous terrain and tourism-dependent economy. Advanced treatment helps minimize nutrient and pollutant loads, preserving water quality for downstream communities and habitats.
