AYGUESVIVES Wastewater Treatment Plant, Ayguesvives, Occitanie, France

AYGUESVIVES is a municipal wastewater treatment plant located in Ayguesvives, a commune in the Haute-Garonne department of Occitanie, southern France. The plant serves a population of approximately 1,900 residents and operates under the regulatory framework of the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. With a designed capacity of 1,950 m³/day and an average daily discharge of 338.96 m³/day, the facility operates well within its capacity, indicating adequate infrastructure for the current population. The treated effluent is discharged into a local watercourse that eventually flows into the Garonne River, a major river in southwestern France. The Garonne drains into the Gironde estuary and then the Atlantic Ocean. The plant plays a key role in protecting the local watershed from nutrient pollution and maintaining water quality in the downstream aquatic ecosystem.

The plant discharges into a tributary of the Garonne River, which flows through the Occitanie region and into the Gironde estuary before reaching the Atlantic Ocean. The Garonne basin supports diverse aquatic life, including migratory fish species such as salmon and eels. Secondary treatment helps reduce organic pollution and nutrient loads, safeguarding the ecological health of the river and its downstream environments.
