Overview
SAINT DENIS DE PILE wastewater treatment plant serves approximately 5,800 residents in Saint-Denis-de-Pile, Nouvelle-Aquitaine, France. It discharges treated effluent into the local watershed within the Gironde department.
The SAINT DENIS DE PILE wastewater treatment plant is located in Saint-Denis-de-Pile, a commune in the Gironde department of Nouvelle-Aquitaine, southwestern France. The facility serves a population of about 5,800 people, classifying it as a small agglomeration under French and EU regulations. As a French wastewater treatment plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or population equivalent), and it is expected to meet national standards for effluent quality. The treated wastewater is discharged into a local watercourse that flows into the Isle River, a tributary of the Dordogne River, which ultimately reaches the Gironde estuary and the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Isle River and the downstream Dordogne-Gironde system, which supports diverse aquatic life and is important for regional ecology.
Environmental context
The plant discharges into a tributary of the Isle River, which flows into the Dordogne River and then the Gironde estuary, a major European estuary that empties into the Atlantic Ocean. The Gironde estuary is ecologically significant, supporting migratory fish species such as Atlantic salmon and European eel, as well as diverse bird populations. The plant's operations help maintain water quality in this sensitive downstream environment.
