The plant serves a population of approximately 51,567, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a French facility, the plant operates under the EU UWWTD (91/271/EEC), which requires secondary treatment for agglomerations of this size.

The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River basin. The Loire is one of France's major rivers, flowing into the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Loire and its tributaries, supporting aquatic ecosystems and downstream communities.

The plant discharges into the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The Loire supports diverse aquatic life, including migratory fish species, and its watershed is ecologically sensitive. Proper treatment helps maintain water quality in this important river system.
