SAVERDUN nouvelle Wastewater Treatment Plant, Saverdun, Occitanie

SAVERDUN nouvelle is a municipal wastewater treatment plant located in Saverdun, a commune in the Ariège department of Occitanie, southern France. The plant serves a population of approximately 2,688 people, classifying it as a small agglomeration under French regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 9,500 m³/day and a current discharge volume of 479.53 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Ariège River, a tributary of the Garonne. The Garonne flows into the Gironde estuary and then the Atlantic Ocean. The plant plays a key role in protecting the Ariège River and downstream ecosystems from untreated wastewater pollution.

The plant discharges into the Ariège River basin, which flows into the Garonne River and eventually reaches the Gironde estuary and the Atlantic Ocean. The Ariège River supports diverse aquatic life and is important for regional biodiversity. The plant's secondary treatment helps reduce organic pollutants and protect the river's ecological health.
