Saint-Georges-sur-Moulon Montboulin Wastewater Treatment Plant, Centre-Val de Loire

The Saint-Georges-sur-Moulon Montboulin wastewater treatment plant is located in the commune of Saint-Georges-sur-Moulon, within the Cher department of the Centre-Val de Loire region in central France. It serves a population of approximately 1,995 residents, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. With a designed capacity of 2,800 cubic meters per day and a current discharge volume of 355.9 cubic meters per day, the facility operates well within its capacity, ensuring effective treatment of local wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River basin. The Loire is France's longest river and a vital ecological corridor, supporting diverse aquatic life and providing water for agriculture and drinking. The plant's advanced treatment helps protect downstream water quality in this sensitive river system.

The plant discharges into the local watercourse, part of the Loire River basin. The Loire River flows through central France before reaching the Atlantic Ocean at the Bay of Biscay. This basin supports a variety of fish species, including Atlantic salmon and European eel, and is an important migratory corridor. Advanced treatment at the plant reduces nutrient loads, helping to prevent eutrophication in downstream waters.
