Overview
LA GRAND COMBE wastewater treatment plant serves Les Salles-du-Gardon, Occitanie, France. It treats wastewater for approximately 15,217 people under the EU Urban Waste Water Treatment Directive.
LA GRAND COMBE is a wastewater treatment plant located in Les Salles-du-Gardon, within the Occitanie region of southern France. The facility serves a population of around 15,217, placing it in the medium agglomeration category under European Union regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. As a French wastewater treatment facility, LA GRAND COMBE operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection, treatment, and discharge of urban wastewater. For agglomerations of this size, the directive typically requires secondary treatment as a minimum, with tertiary treatment in sensitive areas. The plant's treatment processes and capacity are aligned with these regulatory requirements to ensure compliance with environmental standards. The treated effluent from LA GRAND COMBE is discharged into local watercourses that ultimately drain into the Gardon River, a tributary of the Rhône River. The Rhône flows into the Mediterranean Sea, making the plant's operations important for protecting downstream aquatic ecosystems. The region's watershed supports diverse freshwater habitats and is part of a broader network of rivers that sustain agricultural and ecological systems in southern France.
Environmental context
The plant discharges into the Gardon River basin, which flows into the Rhône River and eventually the Mediterranean Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The treatment plant plays a key role in maintaining water quality in this ecologically sensitive area, particularly for downstream habitats and water uses.
