NEUVIC sur L ISLE Wastewater Treatment Plant, Neuvic, Nouvelle-Aquitaine

NEUVIC sur L ISLE is a wastewater treatment plant located in Neuvic, a commune in the Dordogne department of Nouvelle-Aquitaine, southwestern France. The facility serves a population of approximately 3,720 residents, providing advanced treatment to ensure high-quality effluent before discharge. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 4,000 cubic meters per day and an average discharge volume of 663.64 cubic meters per day, the plant operates well within its capacity. As a French facility, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population size and receiving water sensitivity. The treated effluent is discharged into the Isle River watershed, which flows westward through the Dordogne region and eventually joins the Dordogne River near Libourne. The Dordogne River then flows into the Gironde estuary and the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Isle River, supporting aquatic life and downstream ecosystems in the Gironde estuary.

The plant discharges into the Isle River, a tributary of the Dordogne River, which flows into the Gironde estuary and the Atlantic Ocean. The Isle River supports diverse freshwater habitats and is important for migratory fish species such as salmon and eels. The advanced treatment helps reduce nutrient loading, protecting downstream water quality in the ecologically sensitive Gironde estuary.
