Overview
Issoudun wastewater treatment plant serves approximately 59,000 people in Issoudun, Centre-Val de Loire, France. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Issoudun wastewater treatment plant is a municipal facility located in Issoudun, a town in the Indre department of the Centre-Val de Loire region, France. Serving a population of around 59,000, the plant is part of the region's wastewater infrastructure, handling domestic and industrial flows from the urban area. As a French plant serving over 50,000 people, it falls under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum. For larger agglomerations in sensitive areas, tertiary treatment may be mandated. The plant's design and operation align with these European standards, ensuring compliance with discharge limits. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River basin. The Loire is one of France's major rivers, flowing into the Atlantic Ocean. The plant plays a key role in protecting the water quality of the surrounding environment and downstream ecosystems, including the Loire estuary.
Environmental context
The plant discharges into the local watercourse, part of the Loire River basin. The Loire flows westward through central France and empties into the Bay of Biscay (Atlantic Ocean). This watershed supports diverse aquatic life and is an important ecological corridor. The plant's treatment helps reduce nutrient and pollutant loads, safeguarding downstream water quality and the sensitive estuarine environment.
