Overview
Villefranche-de-Rouergue wastewater treatment plant serves about 31,579 people in Occitanie, France. The facility operates under the EU Urban Waste Water Treatment Directive, ensuring compliance with secondary treatment standards for medium agglomera
The Villefranche-de-Rouergue wastewater treatment plant is located in the Aveyron department of Occitanie, southern France. It serves a population of approximately 31,579, classifying it as a medium agglomeration under EU regulations. The plant is situated on Route de Garrials, near the town of Villefranche-de-Rouergue. As a French municipal facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant is expected to meet the directive's standards for biological treatment and nutrient removal where required. The facility's design capacity supports the local population, and it operates within France's national regulatory framework for water sanitation. 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.
