SALIES DU SALAT Wastewater Treatment Plant, Salies-du-Salat, Occitanie

SALIES DU SALAT is a wastewater treatment plant located in Salies-du-Salat, a commune in the Haute-Garonne department of Occitanie, southern France. The plant serves a population of approximately 1,056 residents and is part of the municipal wastewater infrastructure for the area. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,500 m³/day and a current discharge volume of 188.39 m³/day, the plant operates well below its capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Garonne River via the Salat River. The Garonne flows into the Gironde estuary and the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Salat River and downstream ecosystems.

The plant discharges into the Salat River, a tributary of the Garonne River. The Garonne flows through southwestern France and into the Gironde estuary, a major ecological zone supporting diverse aquatic life and migratory fish species. The watershed is part of the Adour-Garonne basin, which is managed under the EU Water Framework Directive to maintain good ecological status.
