Overview
SEYSSEL wastewater treatment plant in Seyssel, Auvergne-Rhône-Alpes, France, serves about 2,074 people with advanced treatment. It discharges 370 cubic meters per day and has a designed capacity of 5,950 cubic meters per day.
The SEYSSEL wastewater treatment plant is located in Seyssel, a commune in the Haute-Savoie department of the Auvergne-Rhône-Alpes region in eastern France. The plant serves a population of approximately 2,074 residents, reflecting its role as a small-scale municipal facility in the Rhône-Alpes region. The plant employs advanced treatment processes, which go beyond the secondary treatment standards required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,950 cubic meters per day and an actual discharge volume of 370 cubic meters per day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhône River basin. The Rhône is one of Europe's major rivers, flowing into the Mediterranean Sea. The advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the Rhône delta and the Gulf of Lion.
Environmental context
The plant discharges into the Rhône River basin, which flows through southeastern France and into the Mediterranean Sea. The Rhône is a major European river supporting diverse aquatic life and providing water for agriculture, industry, and cities. Advanced treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream habitats and the sensitive coastal environment of the Camargue region, an important wetland area.
