The Saint-Dyé-sur-Loire wastewater treatment plant is located in the commune of Saint-Dyé-sur-Loire, within the Loir-et-Cher department of the Centre-Val de Loire region, France. The facility serves a population of approximately 3,258 residents and operates with advanced treatment processes to ensure high-quality effluent. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent French and European standards. The plant has a designed capacity of 7,500 m³/day and currently treats an average daily flow of 581.22 m³/day, indicating ample reserve capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), such small agglomerations (under 10,000 population equivalent) are required to provide appropriate treatment, and advanced treatment is often implemented in sensitive areas. The treated effluent is discharged into the Loire River, which flows through the Centre-Val de Loire region and eventually reaches the Atlantic Ocean. The Loire is a major European river known for its ecological diversity, supporting numerous fish species and migratory birds. The plant's advanced treatment helps protect the river's water quality and downstream ecosystems.
Environmental context
The plant discharges into the Loire River, which flows through the Centre-Val de Loire region and empties into the Bay of Biscay (Atlantic Ocean). The Loire is one of the last wild rivers in Europe, supporting diverse aquatic life including Atlantic salmon and European eel. Advanced treatment at this plant helps reduce nutrient loading, protecting the river's ecological balance and downstream estuarine habitats.
