MURAT BOURG Wastewater Treatment Plant, Albepierre-Bredons, Auvergne-Rhône-Alpes

MURAT BOURG is a wastewater treatment plant located in Albepierre-Bredons, a commune in the Cantal department of Auvergne-Rhône-Alpes, France. The plant serves a population of approximately 2,652 residents and is situated in a rural, mountainous region of the Massif Central. It operates under the French regulatory framework, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 2,083 m³/day and an average discharge volume of 473 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. Advanced treatment typically includes nutrient removal, which is important for protecting sensitive water bodies. The treated effluent is discharged into the local watershed, which ultimately drains into the Alagnon River, a tributary of the Allier, then the Loire, and finally the Atlantic Ocean. The plant plays a key role in preserving water quality in this rural area, supporting aquatic life and downstream ecosystems.

The plant discharges into the Alagnon River basin, part of the Loire River system that flows to the Atlantic Ocean. The region is characterized by volcanic soils and diverse aquatic habitats. The advanced treatment helps protect downstream water quality, particularly for sensitive species such as freshwater pearl mussels and salmonids that inhabit the Loire basin.
