LAVIT Wastewater Treatment Plant, Lavit, Occitanie, France

LAVIT is a wastewater treatment plant located in Lavit, a commune in the Tarn-et-Garonne department of Occitanie, southern France. The plant serves a population of approximately 2,282 residents, classifying it as a small agglomeration under French and EU 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. It has a designed capacity of 1,500 m³/day and currently treats an average daily flow of 407.10 m³/day, indicating significant spare capacity. The treated effluent is discharged into a local watercourse, likely a tributary of the Garonne River, which flows into the Gironde estuary and ultimately the Atlantic Ocean. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from nutrient pollution.

The plant discharges into a small river in the Garonne basin, which drains into the Gironde estuary and the Bay of Biscay. The Garonne watershed supports diverse aquatic life and is important for migratory fish species. Secondary treatment helps reduce organic load and suspended solids, protecting downstream water quality.
