CABANNES Wastewater Treatment Plant, Cabannes, Provence-Alpes-Côte d'Azur

CABANNES is a municipal wastewater treatment plant located in Cabannes, a commune in the Bouches-du-Rhône department of Provence-Alpes-Côte d'Azur, France. The plant serves a population of approximately 4,342 and has a designed capacity of 4,000 m³/day, with an average discharge volume of 774.60 m³/day. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent quality standards. The treated wastewater is discharged into the local watershed, which ultimately drains into the Rhône River delta and the Mediterranean Sea. The plant plays a key role in protecting the Camargue region, a ecologically sensitive area known for its wetlands and diverse birdlife, by reducing nutrient and pollutant loads.

The plant discharges into the Rhône River basin, which flows into the Mediterranean Sea via the Camargue delta. This downstream environment supports diverse aquatic life, including fish and migratory birds, and is ecologically sensitive due to its wetland ecosystems. The plant's secondary treatment helps mitigate nutrient pollution that could otherwise contribute to eutrophication in the coastal zone.
