Overview
CHAGNY wastewater treatment plant serves Chagny, Bourgogne-Franche-Comté, France, treating wastewater for approximately 6,452 residents. The plant operates under the EU Urban Waste Water Treatment Directive.
The CHAGNY wastewater treatment plant is located in Chagny, a commune in the Saône-et-Loire department of Bourgogne-Franche-Comté, France. It serves a population of approximately 6,452 people, classifying it as a small agglomeration under EU regulations. As a French plant, CHAGNY operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The directive mandates secondary treatment for discharges to freshwater, with potential tertiary requirements if the receiving waters are sensitive. The plant's treated effluent ultimately drains into the Saône River, a major tributary of the Rhône, which flows south to the Mediterranean Sea. The Saône basin supports diverse aquatic life and is an important ecological corridor in the region.
Environmental context
The plant discharges into the Saône River, which flows through Burgundy before joining the Rhône near Lyon. The Rhône then empties into the Mediterranean Sea. The Saône basin supports diverse aquatic ecosystems, including fish species such as pike and perch, and provides habitat for migratory birds. The region's agricultural landscape means nutrient management is important to prevent eutrophication downstream.
