SALLES SUR VERDON Wastewater Treatment Plant, Les Salles-sur-Verdon, France

The SALLES SUR VERDON wastewater treatment plant is located in Les Salles-sur-Verdon, a commune in the Var department of Provence-Alpes-Côte d'Azur, France. The plant serves a population of approximately 3,920 residents and has a designed capacity of 3,800 m³/day, with an average daily discharge volume of 699.32 m³. As a secondary treatment facility, the plant provides biological treatment to remove organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent between 2,000 and 10,000 are generally required to have secondary treatment, which this plant meets. The plant operates within the French regulatory framework, which implements the directive through national legislation. The treated effluent is discharged into the local watershed, which ultimately drains into the Verdon River, a tributary of the Durance River. The Durance flows into the Rhône River, which empties into the Mediterranean Sea. The plant plays a key role in protecting the water quality of the Verdon River, a popular destination for water sports and tourism, and supports the ecological health of the downstream aquatic environment.

The plant discharges into the Verdon River, which flows into the Durance River, a major tributary of the Rhône River. The Rhône River ultimately reaches the Mediterranean Sea. The Verdon River is known for its turquoise waters and supports diverse aquatic life, including fish species such as trout and grayling. The area is also part of the Verdon Regional Natural Park, which emphasizes conservation of the river's ecosystem and biodiversity.
