CERIZAY LA RIVIERE Wastewater Treatment Plant, Cerizay, France

CERIZAY LA RIVIERE is a wastewater treatment facility located in Cerizay, within the Nouvelle-Aquitaine region of France. It serves a population of 3,341 and operates with advanced treatment processes to ensure high-quality effluent. The plant is situated inland, away from coastal areas, and plays a key role in managing local wastewater. The plant employs advanced treatment technology, which goes beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 9,033 cubic meters per day and a discharge volume of 596 cubic meters per day, it operates well within its capacity. As a French facility, it adheres to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population and receiving water sensitivity. The treated effluent is discharged into local rivers that eventually flow into the Atlantic Ocean via the Loire River basin. This contributes to protecting downstream ecosystems, including aquatic habitats and water quality in the region. The plant's advanced treatment helps minimize environmental impact on the surrounding watershed.

The plant discharges into local streams that are part of the Loire River basin, which drains into the Bay of Biscay in the Atlantic Ocean. The region supports diverse aquatic life and is important for migratory fish species. Advanced treatment reduces nutrient loading, helping to prevent eutrophication in downstream waters.
