Cheval Blanc Wastewater Treatment Plant, Cheval-Blanc, Provence-Alpes-Côte d'Azur

The Cheval Blanc wastewater treatment plant is located in Cheval-Blanc, a commune in the Vaucluse department of Provence-Alpes-Côte d'Azur, France. It serves a population of approximately 3,400 residents, placing it in the small agglomeration category 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 agglomerations of this size. Its designed capacity is 2,700 m³/day, and it currently treats 606.55 m³/day, indicating significant spare capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Durance River, a major tributary of the Rhône River. The Rhône flows into the Mediterranean Sea near the Camargue delta, an ecologically sensitive area supporting diverse aquatic life and migratory birds.

The plant discharges into the Durance River basin, which feeds into the Rhône River. The Rhône delta and the Mediterranean Sea downstream are ecologically important, supporting diverse aquatic species and serving as a migratory corridor for fish and birds. Advanced treatment helps protect these waters from nutrient pollution.
