Chasse sur Rhone Wastewater Treatment Plant, Seyssuel, Auvergne-Rhone-Alpes, France

The Chasse sur Rhone wastewater treatment plant is located in Seyssuel, a commune in the Isere department of Auvergne-Rhone-Alpes, France. The plant serves a population of approximately 9,792 people, classifying it as a medium-sized agglomeration under European Union regulations. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment process and capacity details are not publicly available, but the regulatory framework ensures compliance with national and European standards. The treated effluent from the plant is discharged into the Rhone River, one of the major rivers in Europe. The Rhone flows southward through France, eventually reaching the Mediterranean Sea near the Camargue delta. This water body supports diverse aquatic life and is an important ecological corridor for migratory fish species.

The plant discharges into the Rhone River, which flows through the Rhone Valley and drains into the Mediterranean Sea. The Rhone basin supports a variety of ecosystems, including wetlands and riparian habitats. The downstream environment includes the Camargue region, a biologically rich area that relies on the river's flow and water quality for its ecological balance.
