ROQUEBRUNE SUR ARGENS Wastewater Treatment Plant, Roquebrune-sur-Argens, France

ROQUEBRUNE SUR ARGENS is a wastewater treatment plant located in Roquebrune-sur-Argens, a commune in the Var department of Provence-Alpes-Côte d'Azur, southeastern France. The plant serves a population of approximately 7,300 residents and has a designed capacity of 1.00 (likely in cubic meters per day or similar unit). It is situated near the Argens River, which flows into the Mediterranean Sea. As a French wastewater treatment facility serving a small agglomeration (under 10,000 population equivalent), the plant is subject to the European Union's Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for discharges into freshwater and estuaries, with more stringent tertiary treatment if the receiving water is designated as sensitive. French regulations typically mandate at least secondary treatment for plants of this scale. The plant's treated effluent is likely discharged into the Argens River or its tributaries, which eventually reach the Mediterranean Sea near Fréjus. The Argens River supports diverse aquatic life and is an important watercourse in the region. The plant's proximity to the coast (within 50 km) means its discharge can affect coastal water quality, particularly in the Bay of Saint-Tropez area.

The plant discharges into the Argens River basin, which flows into the Mediterranean Sea near Fréjus. The Argens River supports a variety of fish species and provides habitat for migratory birds. The coastal zone is ecologically sensitive, with seagrass meadows and marine biodiversity. The plant's effluent, if not adequately treated, could contribute to nutrient loading and affect coastal water quality.
