Overview
SAINT ANDRE DE CORCY Chef lieu is an advanced wastewater treatment plant in Saint-André-de-Corcy, Auvergne-Rhône-Alpes, France, serving about 4,100 people with a design capacity of 4,750 m³/day.
SAINT ANDRE DE CORCY Chef lieu is a municipal wastewater treatment facility located in Saint-André-de-Corcy, a commune in the Ain department of the Auvergne-Rhône-Alpes region, France. The plant serves a population of approximately 4,100 residents, classifying it as a small to medium agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the UWWTD for agglomerations of this size. With a design capacity of 4,750 m³/day and a current discharge volume of 731.43 m³/day, the facility operates well within its capacity. As a French plant, it is subject to national regulations transposing the UWWTD, overseen by the local water agency (Agence de l'Eau). The treated effluent is discharged into the local watershed, which ultimately drains into the Rhône River basin. The plant plays a key role in protecting the region's water quality, supporting the ecological health of downstream water bodies and contributing to the overall management of the Rhône-Mediterranean basin.
Environmental context
The plant discharges into the local water network that feeds into the Rhône River, one of Europe's major rivers flowing into the Mediterranean Sea. The Rhône basin supports diverse aquatic life and is an important migratory corridor for fish species. The advanced treatment helps reduce nutrient loads, protecting downstream ecosystems from eutrophication and maintaining water quality for sensitive areas in the Mediterranean coastal zone.
