SAINT JEOIRE EN FAUCIGNY Wastewater Treatment Plant, Saint-Jeoire, France

The SAINT JEOIRE EN FAUCIGNY wastewater treatment plant is located in Saint-Jeoire, within the Haute-Savoie department of the Auvergne-Rhône-Alpes region, France. It serves a population of 4,418 and is designed to handle a capacity of 2,900 cubic meters per day, with an average discharge volume of 788.16 cubic meters per day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment is typical for plants discharging into sensitive areas, such as alpine watersheds, to protect water quality. The treated effluent is discharged into the local water system, which ultimately drains into the Arve River and then the Rhône River, flowing towards the Mediterranean Sea. The plant plays a key role in protecting the sensitive alpine ecosystem and downstream water bodies from nutrient pollution.

The plant discharges into the Arve River basin, a tributary of the Rhône River, which flows into the Mediterranean Sea. The watershed supports diverse aquatic life and is ecologically sensitive due to its alpine origin and proximity to the Mont Blanc massif. Advanced treatment helps minimize nutrient loading, protecting downstream habitats and water quality.
