COTIGNAC Village Wastewater Treatment Plant, Cotignac, Provence-Alpes-Côte d'Azur

COTIGNAC Village is an advanced wastewater treatment plant located in Cotignac, a commune in the Var department of Provence-Alpes-Côte d'Azur, France. The plant serves a population of 3,309 and is designed to handle a capacity of 2,933 cubic meters per day, with a current discharge volume of 590.32 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment, and the advanced level here indicates compliance with stricter standards, likely due to the sensitivity of the receiving environment. The treated effluent is discharged into local watercourses that eventually drain into the Mediterranean Sea. The region is characterized by a Mediterranean climate and karstic geology, making water resources sensitive to pollution. The plant plays a key role in protecting downstream aquatic ecosystems and supporting the local environment.

The plant discharges into local streams that flow through the Argens River basin before reaching the Mediterranean Sea. The downstream environment includes ecologically sensitive coastal areas that support diverse marine life and seagrass meadows. Advanced treatment helps minimize nutrient loading and protects water quality in this Mediterranean watershed.
