Overview
STE SIGOLENE La BAtie is an advanced wastewater treatment plant in Sainte-Sigolène, Auvergne-Rhône-Alpes, France, serving 3,402 people with a designed capacity of 4,000 m³/day.
STE SIGOLENE La BAtie is an advanced wastewater treatment plant located in Sainte-Sigolène, within the Auvergne-Rhône-Alpes region of France. The plant serves a population of approximately 3,402 residents and has a designed capacity of 4,000 m³/day, with a discharge volume of 606.91 m³/day. It is situated inland, far from coastal areas, and treats wastewater from the local community. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations between 2,000 and 10,000 population equivalent are required to provide secondary treatment, but advanced treatment is often implemented in sensitive areas to protect water quality. The plant's advanced status reflects its commitment to stringent environmental standards. The treated effluent is discharged into a local watercourse that eventually drains into the Loire River basin, which flows into the Atlantic Ocean. The plant plays a crucial role in protecting the local watershed and downstream ecosystems, including the Loire River, which supports diverse aquatic life and is an important ecological corridor in France.
Environmental context
The plant discharges into a tributary of the Loire River, which flows through central France before reaching the Atlantic Ocean. The Loire basin is ecologically significant, supporting diverse fish species, migratory birds, and riparian habitats. Advanced treatment helps minimize nutrient loading and protects water quality in this sensitive watershed.
