Overview
Crêches-sur-Saône wastewater treatment plant serves about 11,400 people in Bourgogne-Franche-Comté, France. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
The Crêches-sur-Saône wastewater treatment plant is located in the commune of Crêches-sur-Saône, within the Saône-et-Loire department of Bourgogne-Franche-Comté, France. It serves a population of approximately 11,400 residents, classifying it as a medium-sized agglomeration under European Union regulations. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes are designed to meet these standards, ensuring compliance with national and European water quality goals. The treated effluent is discharged into the Saône River, a major tributary of the Rhône, which flows southward to the Mediterranean Sea. The Saône River supports diverse aquatic life and is an important ecological corridor in the region. The plant's operation helps protect downstream water quality and the broader Rhône basin ecosystem.
Environmental context
The plant discharges into the Saône River, which joins the Rhône River near Lyon. The Rhône then flows into the Mediterranean Sea. The Saône basin supports a variety of fish species and riparian habitats, and the plant's treatment helps maintain water quality for downstream communities and ecosystems.
