BARAQUEVILLE Wastewater Treatment Plant, Baraqueville, Occitanie, France

The BARAQUEVILLE wastewater treatment plant is located in Baraqueville, a commune in the Aveyron department of Occitanie, southern France. It serves a population of approximately 2,567 people, classifying it as a small agglomeration under French regulations. The plant is situated inland, away from coastal areas, and treats wastewater from the local community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 2,675 m³ per day, with an average daily discharge volume of 457.95 m³, indicating significant spare capacity. The facility is part of France's national wastewater infrastructure, managed under the regulatory framework of the French Ministry of Ecological Transition. The treated effluent is discharged into the local watershed, which ultimately drains into the Aveyron River, a tributary of the Tarn River, and then into the Garonne River before reaching the Atlantic Ocean. The plant plays a key role in protecting the water quality of these rivers and the downstream ecosystems, including the Garonne estuary and the Bay of Biscay.

The BARAQUEVILLE plant discharges into the local watershed that feeds the Aveyron River, a tributary of the Tarn River, which flows into the Garonne River and eventually reaches the Atlantic Ocean. The Garonne River supports diverse aquatic life and is an important migratory corridor for species such as Atlantic salmon and European eel. The advanced treatment helps minimize nutrient and pollutant loads, protecting the ecological health of these downstream water bodies.
