LANCIE Wastewater Treatment Plant, Corcelles-en-Beaujolais, Auvergne-Rhône-Alpes

LANCIE is a wastewater treatment plant located in Corcelles-en-Beaujolais, within the Auvergne-Rhône-Alpes region of France. It serves a population of approximately 1,927 people, making it a small agglomeration under French regulations. The plant provides secondary treatment, which is the standard level required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 5,333 m³/day and an average discharge volume of 343.77 m³/day, the plant operates well below its capacity. 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 operations relevant to downstream water quality in this ecologically significant river system.

The plant discharges into the Saône River basin, which flows into the Rhône River and eventually reaches the Mediterranean Sea. This watershed supports diverse aquatic life and is an important migratory corridor for fish species. The region's temperate climate and agricultural land use mean that nutrient management from wastewater is critical to prevent eutrophication in downstream water bodies.
