The plant serves a population of approximately 60,533 people, placing it in the medium-to-large agglomeration category under EU classification. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size.

The plant discharges treated effluent into the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The Loire is one of France's major rivers, supporting diverse aquatic life and providing water for agriculture and communities downstream. The plant plays a key role in protecting the Loire's water quality and the ecological health of its watershed.

The plant discharges into the Loire River basin, which drains into the Bay of Biscay (Atlantic Ocean). The Loire is a vital ecological corridor supporting fish species such as Atlantic salmon and European eel. The plant's treatment helps maintain water quality in this important river system, which is subject to nutrient pollution pressures from agriculture and urban runoff.
