UZES Wastewater Treatment Plant, Uzès, Occitanie, France

The UZES wastewater treatment plant is located in Uzès, a historic town in the Gard department of Occitanie, southern France. Serving a population equivalent of around 16,404, the plant is part of the municipal infrastructure managed by the local authority. As a medium-sized agglomeration, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum standard. Under the EU UWWTD, agglomerations with a population equivalent between 10,000 and 150,000 must achieve secondary treatment, and if discharging into sensitive areas, more stringent tertiary treatment may be required. The regulatory framework ensures compliance with national and European standards for effluent quality. The treated wastewater from UZES is discharged into the local watercourse, which flows into the Gardon River, a tributary of the Rhône. The Rhône River ultimately drains into the Mediterranean Sea. The plant plays a key role in protecting the local aquatic ecosystem and downstream water quality, supporting biodiversity in the region's rivers and coastal waters.

The UZES plant discharges into the Gardon River, a tributary of the Rhône River, which flows into the Mediterranean Sea. The Gardon River supports diverse aquatic life and is part of a sensitive karst landscape. The plant's operation helps maintain water quality in this ecologically important watershed, which is also used for recreation and agriculture.
