Overview
MEYREUIL PONTET CHEF LIEU is a secondary wastewater treatment plant in Meyreuil, Provence-Alpes-Côte d'Azur, France, serving approximately 4,920 people with a designed capacity of 4,000 m³/day.
MEYREUIL PONTET CHEF LIEU is a municipal wastewater treatment plant located in Meyreuil, a commune in the Bouches-du-Rhône department of Provence-Alpes-Côte d'Azur, France. The plant serves a population of approximately 4,920 and has a designed capacity of 4,000 m³/day, with an average discharge volume of 877.72 m³/day. It is situated inland, more than 10 km from the coast, and treats wastewater to secondary level. The plant operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size (between 2,000 and 10,000 population equivalent). French regulations transpose this directive, and the plant is likely subject to permits issued by the local water agency (Agence de l'Eau). Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea via the Arc River or its tributaries. The region is part of the Provence-Alpes-Côte d'Azur water basin, characterized by a Mediterranean climate with dry summers and occasional heavy rainfall. The downstream environment supports diverse aquatic life and is important for regional water resources.
Environmental context
The plant discharges into the local watershed within the Arc River basin, which flows into the Étang de Berre lagoon and then the Mediterranean Sea. This coastal lagoon is an ecologically sensitive area supporting diverse aquatic life, including fish and bird species. The region's Mediterranean climate means the plant must manage seasonal variations in flow and potential pollution from urban runoff.
