Overview
Pont-de-Vaux wastewater treatment plant serves approximately 7,250 people in Auvergne-Rhône-Alpes, France. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
The Pont-de-Vaux wastewater treatment plant is located in the commune of Pont-de-Vaux, within the Ain department of the Auvergne-Rhône-Alpes region in eastern France. The facility serves a population of approximately 7,250 residents, classifying it as a small to medium agglomeration under EU regulations. As a French wastewater treatment plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 2,000 and 10,000 discharging into freshwater. The plant's treatment processes are designed to meet these standards, ensuring compliance with national and European environmental regulations. The treated effluent is discharged into the local watershed, which ultimately drains into the Saône River, a major tributary of the Rhône. The Rhône flows into the Mediterranean Sea, making the plant's performance important for downstream water quality. The region's aquatic ecosystems benefit from effective nutrient removal and pollution control, supporting biodiversity in the Saône and Rhône river systems.
Environmental context
