Beaumont Wastewater Treatment Plant, Beaumont-de-Lomagne, Occitanie

The Beaumont wastewater treatment plant is located in Beaumont-de-Lomagne, a commune in the Occitanie region of southern France. The facility serves a population of approximately 5,260 residents and is situated near the Lomagnol leisure park, reflecting its integration into the local landscape. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. With a designed capacity of 7,000 m³/day and an actual discharge volume of 938.37 m³/day, the plant operates well within its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Garonne River via the Gimone or related tributaries. The Garonne flows into the Gironde estuary and then the Atlantic Ocean. Advanced treatment helps protect the sensitive aquatic ecosystems of the Garonne basin, supporting biodiversity and water quality downstream.

The plant discharges into the Garonne River basin, a major watercourse in southwestern France that flows into the Gironde estuary and the Atlantic Ocean. The Garonne supports diverse aquatic life and is an important migratory corridor for fish species such as salmon and eels. Advanced treatment at this plant helps reduce nutrient loading and protect the ecological health of the river and its downstream environments.
