LUZY_Ville Wastewater Treatment Plant, Luzy, Bourgogne-Franche-Comté

LUZY_Ville is a municipal wastewater treatment plant located in Luzy, a commune in the Nièvre department of Bourgogne-Franche-Comté, France. The plant serves a population of around 3,015 and has a designed capacity of 4,400 m³/day, with an average discharge volume of 537.87 m³/day. It is situated inland, far from coastal areas, and operates under France's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU directive for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. As a French facility, it is subject to national regulations that transpose the EU directive, with permits issued by the local water agency (Agence de l'Eau). The treated effluent is discharged into a local watercourse that ultimately drains into the Loire River basin, one of France's major river systems. The Loire basin supports diverse aquatic ecosystems and is ecologically significant, hosting migratory fish species such as Atlantic salmon and European eel. The plant's advanced treatment helps minimize nutrient loading and protect downstream water quality.

The plant discharges into a tributary of the Loire River, which flows through central France before emptying into the Atlantic Ocean. The Loire basin is a large, ecologically diverse watershed that supports numerous fish species and provides important habitat for migratory birds. Advanced treatment at this plant reduces the risk of eutrophication in downstream waters, contributing to the ecological health of the Loire estuary and coastal zone.
