LE POUGET Bourg Wastewater Treatment Plant, Le Pouget, Occitanie

LE POUGET Bourg is a municipal wastewater treatment plant located in Le Pouget, a commune in the Hérault department of Occitanie, southern France. The plant serves a population of 2,000 and operates under the regulatory framework of the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment of wastewater in agglomerations of this scale. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids, meeting the minimum requirements for agglomerations between 2,000 and 10,000 population equivalent under the EU directive. The plant has a designed capacity of 3,000 m³/day and currently treats an average daily volume of 356.80 m³, indicating significant spare capacity for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Mediterranean Sea via the Hérault River basin. The plant plays a key role in protecting the region's water quality, supporting both agricultural irrigation and the ecological health of downstream aquatic habitats, which include sensitive coastal lagoons and marine environments.

The plant discharges into the Hérault River basin, which flows southward through Occitanie and enters the Mediterranean Sea near Agde. The downstream environment includes the Thau Lagoon, a large coastal lagoon of ecological importance that supports diverse aquatic life, including shellfish farming and migratory bird populations. The region's Mediterranean climate leads to seasonal variations in river flow, making consistent wastewater treatment critical for maintaining water quality during dry summer months.
