COUDOUX VENTABREN VELAUX is a wastewater treatment plant located in Coudoux, within the Aix-en-Provence area of Bouches-du-Rhône, Provence-Alpes-Côte d'Azur, France. The plant serves a population of approximately 14,715, classifying it as a medium-sized agglomeration under EU regulations. As a French facility, this plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent discharging into freshwater or estuaries. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a scale appropriate for its service population. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Mediterranean Sea via the Étang de Berre or the Rhône River delta. This region supports diverse aquatic life and is an important ecological corridor for migratory birds and fish species in the Camargue area.
Environmental context
The plant discharges into the Arc River basin, which flows into the Étang de Berre, a large lagoon connected to the Mediterranean Sea. This coastal lagoon supports diverse aquatic life, including fish nurseries and migratory bird populations. The region is ecologically sensitive due to its Mediterranean climate and the importance of water quality for both tourism and biodiversity.
