Overview
Mercurey wastewater treatment plant serves the commune of Mercurey in Bourgogne-Franche-Comté, France. It treats wastewater for approximately 9,123 people under the EU Urban Waste Water Treatment Directive.
The Mercurey wastewater treatment plant is located in the commune of Mercurey, in the Saône-et-Loire department of the Bourgogne-Franche-Comté region, France. The facility serves a population of approximately 9,123 people, placing it in the category of a small to medium agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). As a plant serving fewer than 10,000 population equivalents, it is subject to the directive's requirements for appropriate treatment, typically secondary treatment, to protect the receiving environment. The plant operates within the French regulatory framework, which implements EU directives through national legislation, and is likely overseen by the local water agency (Agence de l'Eau). The treated effluent from the plant is discharged into the local watershed, which ultimately drains towards the Saône River, a major tributary of the Rhône. The Rhône flows into the Mediterranean Sea. The plant's operation helps protect the water quality of the Saône and downstream ecosystems, including the Rhône delta and the Mediterranean coastal zone.
Environmental context
The plant discharges into the local watercourse that feeds the Saône River, a significant tributary of the Rhône. The Rhône basin supports diverse aquatic life and is an important migratory corridor for fish species. Downstream, the Rhône delta and the Mediterranean Sea receive the cumulative effects of wastewater discharges from numerous agglomerations, making treatment standards critical for coastal water quality.
Frequently asked questions
The plant is located on Route d'Autun, in the Bourgneuf-Val-d'Or area of Mercurey, Saône-et-Loire, Bourgogne-Franche-Comté, France.
The plant serves approximately 9,123 people in the commune of Mercurey and surrounding areas.
The treated effluent is discharged into the local watershed, which flows into the Saône River, a major tributary of the Rhône River that ultimately reaches the Mediterranean Sea.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. French national regulations implement this directive.
For agglomerations between 2,000 and 10,000 population equivalents, the EU directive mandates secondary treatment (biological treatment) to reduce organic matter and suspended solids. French plants typically use activated sludge or similar processes.
