SOMMIERES Wastewater Treatment Plant, Sommières, Occitanie, France

The SOMMIERES wastewater treatment plant is located in Sommières, a town in the Gard department of Occitanie, southern France. The facility serves a population of approximately 8,277 and has a designed capacity of 1.00 (likely in thousands of cubic meters per day or population equivalent). It is situated near the Vidourle River, which flows through the region. As a French wastewater treatment plant serving a medium-sized agglomeration, SOMMIERES operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater bodies. French regulations typically mandate at least secondary treatment for communities of this size. The treated effluent from SOMMIERES is discharged into the local watershed, likely the Vidourle River, which flows southward into the Mediterranean Sea near Le Grau-du-Roi. The Vidourle is a coastal river with a Mediterranean hydrological regime, supporting diverse aquatic life and providing water for agriculture. The plant plays a key role in protecting the water quality of the river and the downstream coastal environment.

The SOMMIERES plant discharges into the Vidourle River, a coastal river in Occitanie that flows into the Mediterranean Sea. The Vidourle watershed supports a variety of aquatic species and is important for local agriculture and tourism. The river's Mediterranean climate means it experiences seasonal flow variations, with flash floods in autumn and low flows in summer, making consistent wastewater treatment crucial for maintaining water quality and ecological health.
