Bédarrides Wastewater Treatment Plant - Advanced Treatment in Provence-Alpes-Côte d'Azur

The Bédarrides wastewater treatment plant is located in the commune of Bédarrides, within the Vaucluse department of Provence-Alpes-Côte d'Azur, France. It serves a population of approximately 3,500 residents, classifying it as a small agglomeration under French and EU regulations. 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 inland plants. Its designed capacity is 5,920 m³ per day, with an actual discharge volume of 624.39 m³ per day, indicating significant reserve capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhône River, a major European waterway flowing into the Mediterranean Sea. The plant's advanced treatment helps protect the Rhône basin and downstream ecosystems, including the Camargue delta, a region of high ecological importance.

The plant discharges into the Rhône River basin, which flows through southeastern France into the Mediterranean Sea. The Rhône is a major river supporting diverse aquatic life and providing water for agriculture and urban use. Downstream, the Camargue region is an ecologically sensitive delta with extensive wetlands and migratory bird habitats. Advanced treatment at Bédarrides helps reduce nutrient and pollutant loads, protecting these downstream environments.
