TENCE Le Bourg is a wastewater treatment plant located in the commune of Tence, within the Haute-Loire department of Auvergne-Rhône-Alpes, France. The plant serves a population of approximately 2,525 residents, classifying it as a small agglomeration under French and EU regulations. It is situated inland, away from coastal areas, and treats wastewater from the local community. The plant employs advanced treatment processes, going beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 1,970 cubic meters per day and an average daily discharge volume of 450.46 cubic meters, the plant operates well within its capacity. The advanced treatment ensures high-quality effluent, reducing nutrients and pollutants to protect the receiving environment. The treated effluent is discharged into a local watercourse, which eventually flows into the Loire River basin. The Loire is France's longest river and a vital ecological corridor, supporting diverse aquatic life and providing water for agriculture and human use. The plant's advanced treatment helps maintain water quality in this sensitive watershed, contributing to the overall health of the Loire River system.
Environmental context
The plant discharges into a tributary of the Loire River, which flows through central France before emptying into the Atlantic Ocean. The Loire basin is ecologically significant, hosting diverse fish species and migratory birds. Advanced treatment at this plant helps reduce nutrient loads, protecting downstream water quality and supporting the river's ecological balance.
