SAINT SYLVESTRE Wastewater Treatment Plant, Saint-Sylvestre, Auvergne-Rhone-Alpes

The SAINT SYLVESTRE wastewater treatment plant is located in Saint-Sylvestre, a commune in the Haute-Savoie department of the Auvergne-Rhone-Alpes region, France. The plant serves a population of 2,819 and operates with advanced treatment, reflecting the high standards of wastewater management in the region. As a facility in France, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The advanced treatment level indicates that the plant likely employs tertiary processes such as nutrient removal to protect sensitive receiving waters. The designed capacity of 5,250 m3/day suggests the plant is sized to accommodate future growth. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Rhone River basin. The Rhone is one of Europe's major rivers, flowing into the Mediterranean Sea. The advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the Rhone delta and coastal waters.

The plant discharges into the local watershed that feeds into the Rhone River, which flows through southeastern France into the Mediterranean Sea. The Rhone basin supports diverse aquatic life and is an important migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient loads, protecting downstream water quality and the sensitive coastal environment of the Camargue region.
