Overview
ALLASSAC wastewater treatment plant serves the commune of Allassac in Nouvelle-Aquitaine, France. It provides secondary treatment for a population of 1,520 and has a designed capacity of 6,200 m³/day.
The ALLASSAC wastewater treatment plant is located in the commune of Allassac, within the Corrèze department of Nouvelle-Aquitaine, France. It serves a population of approximately 1,520 residents, making it a small-scale municipal facility. The plant is situated at an inland location, away from coastal areas, and treats wastewater from the local community. As a secondary treatment facility, ALLASSAC employs biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 6,200 m³/day, with an average daily discharge volume of 271.17 m³, indicating it operates well below its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like Allassac are required to provide appropriate treatment, and secondary treatment meets the directive's standards for inland freshwater discharges. The treated effluent is discharged into the local watershed, which ultimately drains into the Vézère River, a tributary of the Dordogne River. The Dordogne flows westward to the Gironde estuary and the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Vézère and Dordogne rivers, which support diverse aquatic life and are important for regional ecology and tourism.
Environmental context
The ALLASSAC plant discharges into the Vézère River, a tributary of the Dordogne River, which flows into the Gironde estuary and the Atlantic Ocean. The Vézère and Dordogne watersheds are ecologically sensitive, supporting diverse aquatic species and serving as important migratory corridors for fish. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding water quality in this inland river system.
