Pertuis ville Wastewater Treatment Plant, Le Puy-Sainte-Réparade, France

Pertuis ville is a wastewater treatment plant located in Le Puy-Sainte-Réparade, a commune in the Bouches-du-Rhône department of Provence-Alpes-Côte d'Azur, France. The plant serves a population equivalent of 25,000, placing it in the medium agglomeration category under EU regulations. As a French facility, Pertuis ville is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant discharges into the local watershed, which ultimately drains into the Mediterranean Sea via the Durance River and the Rhône River. The region's aquatic ecosystems support diverse species and are important for migratory birds. The plant's operation helps protect downstream water quality in this ecologically sensitive area.

The plant's treated effluent flows into the Durance River, a major tributary of the Rhône River, which then empties into the Mediterranean Sea near the Camargue delta. This watershed supports diverse aquatic life and is an important corridor for migratory fish and birds. The region's Mediterranean climate and agricultural activities make water quality management critical for both ecological and human uses.
