COURPIERE Bourg is a municipal wastewater treatment plant located in Courpière, within the Puy-de-Dôme department of the Auvergne-Rhône-Alpes region in central France. The facility serves a population of approximately 3,390 residents, classifying it as a small agglomeration under French and European regulatory frameworks. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity is 5,833 cubic meters per day, with an average daily discharge volume of 604.77 cubic meters, indicating operational headroom. The treated effluent is discharged into the local water environment, ultimately draining into the Loire River basin via the Dore River. This contributes to the water quality management of the Loire, one of France's major rivers, which flows into the Atlantic Ocean. The plant plays a role in protecting downstream aquatic ecosystems and supporting regional water resource sustainability.
Environmental context
The plant discharges into the Dore River, a tributary of the Allier River, which flows into the Loire River. The Loire basin is ecologically significant, supporting diverse aquatic life including migratory fish species such as Atlantic salmon and European eel. The secondary treatment provided helps reduce nutrient and organic pollution, mitigating eutrophication risks in downstream water bodies.
