NOGENT LE ROI CHAUDON Wastewater Treatment Plant, Chaudon, France

The NOGENT LE ROI CHAUDON wastewater treatment plant is located in Chaudon, within the Centre-Val de Loire region of France. It serves a population of around 7,948 people, classifying it as a small to medium agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from coastal areas, and its operations are part of the municipal wastewater infrastructure for the Dreux area. As a French facility, the plant operates under the EU UWWTD (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the discharge enters sensitive areas. It is expected to meet the secondary treatment standard as a minimum. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Seine River basin. The Seine River flows through Paris and into the English Channel, supporting diverse aquatic life and serving as an important ecological corridor. The plant plays a key role in protecting downstream water quality in this sensitive watershed.
