Overview
Saint-Junien wastewater treatment plant serves approximately 23,900 people in Nouvelle-Aquitaine, France. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Saint-Junien wastewater treatment plant is located in Saint-Junien, Haute-Vienne, in the Nouvelle-Aquitaine region of France. It serves a population of approximately 23,900, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated along Route d'Angoulême near Le Moulin Pelgros. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent between 10,000 and 150,000 are required to provide secondary treatment, unless the receiving waters are designated as sensitive areas, which may necessitate tertiary treatment. It is expected to comply with these standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Vienne River and the Loire River. The plant plays a key role in protecting the water quality of these rivers and the downstream environment, supporting aquatic life and recreational uses.
Environmental context
The plant discharges into the Vienne River basin, which flows into the Loire River and eventually reaches the Atlantic Ocean. The Loire is one of France's longest rivers and supports diverse aquatic ecosystems, including migratory fish species such as Atlantic salmon and European eel. The plant's operations help maintain water quality in this ecologically important watershed.
