MAURIAC BOURG EST is an advanced wastewater treatment plant located in Le Vigean, near Mauriac, in the Cantal department of Auvergne-Rhône-Alpes, France. The plant serves a population of around 3,472 and has a design capacity of 10,000 m³/day, with a current discharge volume of 619.4 m³/day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment is typically implemented in sensitive areas to reduce nutrient loads and protect receiving water bodies. The treated effluent is discharged into local waterways that eventually drain into the Dordogne River basin, which flows into the Atlantic Ocean via the Gironde estuary. The plant's advanced treatment helps safeguard the ecological health of these downstream aquatic environments.
Environmental context
The plant discharges into the local watershed, which is part of the Dordogne River basin. This basin supports diverse aquatic life and is an important migratory corridor for fish species such as Atlantic salmon and European eel. The advanced treatment reduces nutrient pollution, protecting downstream water quality in the Dordogne and its estuary.
