Denice Les Bruyeres Wastewater Treatment Plant, Denicé, Auvergne-Rhône-Alpes

Denice Les Bruyeres is an advanced wastewater treatment plant located in Denicé, within the Auvergne-Rhône-Alpes region of France. The facility serves a population of approximately 1,754 people and has a designed capacity of 4,500 cubic meters per day, with an average discharge volume of 312.91 m³/day. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For small agglomerations like Denicé, the directive requires appropriate treatment to protect receiving water bodies, and advanced treatment is often implemented in sensitive areas. The plant discharges treated effluent 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 important for downstream water quality and aquatic ecosystems.

The plant discharges into the Saône River basin, which flows into the Rhône River and then the Mediterranean Sea. The Saône supports diverse aquatic life and is used for recreation and agriculture. Advanced treatment helps reduce nutrient loading, protecting downstream ecosystems from eutrophication and maintaining water quality in the Rhône delta.
