LA CRAU VALLEE DU GAPEAU is a wastewater treatment plant located in La Crau, a commune in the Var department of the Provence-Alpes-Côte d'Azur region in southeastern France. The plant serves an estimated population of 61,223, classifying it as a medium-to-large agglomeration under EU regulations. Its address is Chemin de Ubac, Les Martins, La Crau, Toulon, Var, Provence-Alpes-Côte d'Azur, France métropolitaine, 83260. As a French wastewater facility, the plant operates within the framework of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment for agglomerations with a population equivalent (PE) greater than 2,000. For plants serving over 10,000 PE in sensitive areas, tertiary treatment (nutrient removal) may be required. The designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating the plant's infrastructure is sized to handle the local wastewater load. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The region is characterized by a Mediterranean climate with dry summers and wet winters, influencing seasonal flow variations in receiving water bodies. The plant plays a key role in protecting downstream aquatic ecosystems, including coastal waters and marine habitats, from nutrient pollution and pathogens.
Environmental context
The plant discharges into the local watershed that flows toward the Mediterranean Sea, likely via the Gapeau River or its tributaries. The downstream environment includes coastal lagoons and marine habitats that are ecologically sensitive, supporting diverse aquatic life such as fish, mollusks, and migratory birds. Effective treatment is crucial to prevent eutrophication and maintain water quality in these ecosystems, which are also important for tourism and fisheries in the Provence-Alpes-Côte d'Azur region.
Frequently asked questions
The plant is located at Chemin de Ubac, Les Martins, La Crau, in the Var department of Provence-Alpes-Côte d'Azur, France.
The plant serves approximately 61,223 people, classifying it as a medium-to-large agglomeration under EU regulations.
Treated wastewater is discharged into the local watershed, which flows into the Mediterranean Sea, likely via the Gapeau River or its tributaries.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 2,000 PE and may require tertiary treatment in sensitive areas.
For agglomerations of this size, French plants typically provide secondary biological treatment, and if discharging into sensitive areas (e.g., coastal zones), tertiary treatment for nutrient removal is often required.
