FLASSANS SUR ISSOLE Village Wastewater Treatment Plant, Flassans-sur-Issole, France

FLASSANS SUR ISSOLE Village is a wastewater treatment facility located in the commune of Flassans-sur-Issole, within the Var department of the Provence-Alpes-Côte d'Azur region in southeastern France. The plant serves a population of approximately 2,312 residents and is situated along the Route du Seuil de l'Issole. The plant employs advanced treatment processes, which go beyond the secondary treatment requirements mandated by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,900 m³/day and an average discharge volume of 412.46 m³/day, the facility operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea via the Issole River and the larger Argens River system. The plant plays a key role in protecting the water quality of these water bodies, supporting aquatic life and downstream ecosystems in the region.

The plant discharges into the Issole River, a tributary of the Argens River, which flows into the Mediterranean Sea near Fréjus. This coastal watershed supports diverse aquatic habitats and is important for regional biodiversity. The advanced treatment level helps minimize nutrient and pollutant loads, protecting the sensitive marine environment of the Côte d'Azur.
