Overview
UZERCHE wastewater treatment plant serves the commune of Uzerche in Nouvelle-Aquitaine, France. It provides advanced treatment for a population of 3,283, with a designed capacity of 5,000 m³/day.
The UZERCHE wastewater treatment plant is located in Uzerche, a commune in the Corrèze department of Nouvelle-Aquitaine, southwestern France. The facility serves a population of approximately 3,283 residents and is designed to handle a capacity of 5,000 cubic meters per day, with an average discharge volume of 585.68 m³/day. As an advanced treatment plant, 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 likely employs processes such as nutrient removal or tertiary filtration to meet stringent effluent standards, particularly relevant for sensitive receiving environments. The treated effluent is discharged into the local watershed, which ultimately drains into the Vézère River, a tributary of the Dordogne River. The Dordogne flows westward to the Gironde estuary and the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Vézère and downstream ecosystems, which support diverse aquatic life and are valued for recreation and biodiversity.
Environmental context
The plant discharges into the Vézère River, a major tributary of the Dordogne River system. The Dordogne flows through the Périgord region and joins the Garonne to form the Gironde estuary, a large coastal ecosystem on the Atlantic. The Vézère and Dordogne watersheds support diverse aquatic habitats, including fish populations such as Atlantic salmon and migratory species. The advanced treatment helps minimize nutrient loading and protects downstream water quality in this ecologically sensitive river network.
Frequently asked questions
