QUINCIEUX LE BOURG Wastewater Treatment Plant, Quincieux, Auvergne-Rhône-Alpes

QUINCIEUX LE BOURG is a wastewater treatment plant located in Quincieux, a commune in the Auvergne-Rhône-Alpes region of France. The plant serves a population of approximately 1,800 people and is part of the municipal infrastructure managed by the local authority. It is situated near the D51 road, within the Lyon metropolitan area. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 2,700 m³/day and an actual discharge volume of 322.19 m³/day, the plant operates well below its capacity, indicating room for future growth. As a French facility, it operates under the national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The treated effluent is discharged into the local watershed, which ultimately drains into the Saône River and then the Rhône River, a major European waterway flowing into the Mediterranean Sea. The plant plays a key role in protecting the water quality of these rivers and the downstream environment, including the Camargue delta and the Gulf of Lion.

The plant discharges into the local watershed that feeds the Saône River, a tributary of the Rhône River. The Rhône flows through southeastern France into the Mediterranean Sea, supporting diverse aquatic ecosystems and important migratory fish species. The advanced treatment helps reduce nutrient and pollutant loads, safeguarding water quality in the Rhône basin and the coastal marine environment.
