LAMANON Wastewater Treatment Plant, Lamanon, Provence-Alpes-Côte d'Azur

LAMANON is a wastewater treatment plant located in Lamanon, a commune in the Bouches-du-Rhône department of Provence-Alpes-Côte d'Azur, France. The plant serves a population of approximately 1,963 residents and is part of the municipal wastewater infrastructure for the area. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. The designed capacity is 2,800 m³/day, and the current discharge volume is 350.20 m³/day, indicating operational headroom. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea via the Rhône River basin. The plant plays a key role in protecting the region's water quality, particularly given the proximity to the coast (within 50 km) and the ecological sensitivity of the Mediterranean coastal environment.

The plant discharges into the local water system within the Rhône River basin, which flows into the Mediterranean Sea. The downstream environment includes the Camargue region, a vast delta and wetland area that supports diverse aquatic life and migratory birds. The Mediterranean coastal zone is ecologically sensitive, with seagrass meadows and marine habitats that benefit from controlled nutrient and pollutant loads.
