POUZIN Wastewater Treatment Plant, Le Pouzin, Auvergne-Rhône-Alpes, France

The POUZIN wastewater treatment plant is located in Le Pouzin, a commune in the Ardèche department of the Auvergne-Rhône-Alpes region in southeastern France. The plant serves a population of approximately 5,971 people, classifying it as a small to medium agglomeration under EU regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment (biological treatment) for their wastewater. The directive aims to protect the environment from the adverse effects of urban wastewater discharges. The plant is expected to comply with these standards. The treated effluent from the POUZIN plant is discharged into the Rhône River, one of the major rivers in Europe. The Rhône flows southward through France and eventually empties into the Mediterranean Sea. The plant plays a crucial role in protecting the water quality of the Rhône and its downstream ecosystems, including the Camargue delta, a region of high ecological importance.

The POUZIN plant discharges into the Rhône River, which flows through southeastern France and into the Mediterranean Sea. The Rhône basin supports diverse aquatic life and is an important migratory corridor for fish species. The downstream Camargue region is a vast wetland complex that relies on the river's flow and water quality. Effective wastewater treatment at POUZIN helps reduce nutrient and pollutant loads, safeguarding these sensitive ecosystems.
