Saint-Privat-des-Vieux Wastewater Treatment Plant - Advanced Treatment in Occitanie, France

The Saint-Privat-des-Vieux wastewater treatment plant is located in the Gard department of Occitanie, southern France. It serves a population of approximately 4,803 residents in the commune of Saint-Privat-des-Vieux and surrounding areas. The plant operates with advanced treatment technology, ensuring high-quality effluent before discharge. As an advanced treatment facility, it goes beyond the secondary treatment requirements mandated by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 3,000 m³/day and currently treats an average daily volume of 856.85 m³, indicating ample reserve capacity for future growth. The treated wastewater is discharged into the local watershed, which ultimately drains into the Gardon River and then the Rhône River before reaching the Mediterranean Sea. The plant plays a vital role in protecting the region's water resources and supporting the ecological health of downstream aquatic habitats.

The plant discharges into the Gardon River basin, a tributary of the Rhône River, which flows into the Mediterranean Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The advanced treatment level helps minimize nutrient loading and protect downstream water quality in the sensitive Mediterranean coastal zone.
