CHAMBON SUR LIGNON LE Le Bourg Wastewater Treatment Plant, Le Chambon-sur-Lignon, France

CHAMBON SUR LIGNON LE Le Bourg is an advanced wastewater treatment plant located in Le Chambon-sur-Lignon, a commune in the Haute-Loire department of the Auvergne-Rhône-Alpes region in central France. The plant serves a population of approximately 3,027 residents and is part of the municipal infrastructure managing wastewater for this small agglomeration. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a designed capacity of 2,233.00 m³/day and an average discharge volume of 540.01 m³/day, the facility operates well within its capacity. As a French plant, it complies with the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate 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 France's longest river and flows into the Atlantic Ocean, supporting diverse aquatic ecosystems along its course. The plant's advanced treatment helps protect downstream water quality and ecological health.

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 such as Atlantic salmon and European eel. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters and maintain the ecological balance of the river system.
