Masseret Bourg Wastewater Treatment Plant, Masseret, Nouvelle-Aquitaine

Masseret Bourg is a wastewater treatment plant located in the commune of Masseret, within the Corrèze department of Nouvelle-Aquitaine, France. The plant serves a population of around 2,100 residents, classifying it as a small agglomeration under French and EU regulations. As a secondary treatment facility, Masseret Bourg provides biological treatment to remove organic matter and suspended solids. The plant has a designed capacity of 2,100 cubic meters per day and currently discharges approximately 374.64 cubic meters of treated effluent daily. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), secondary treatment is the standard requirement for freshwater discharges from agglomerations of this size. The treated effluent from Masseret Bourg is discharged into local watercourses that ultimately drain into the Vézère River, a tributary of the Dordogne. The Dordogne River flows westward through the Aquitaine region before reaching the Gironde estuary and the Atlantic Ocean. The plant plays a key role in protecting the water quality of these downstream rivers and the sensitive ecosystems they support.

The treated effluent from Masseret Bourg enters local streams that feed into the Vézère River, a major tributary of the Dordogne. The Dordogne basin is ecologically significant, supporting diverse aquatic life including salmonid populations and migratory fish species. The river system ultimately reaches the Gironde estuary and the Atlantic Ocean. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding water quality in this important watershed.
