NOZAY Wastewater Treatment Plant, Nozay, Pays de la Loire, France

The NOZAY wastewater treatment plant is located in Nozay, within the Loire-Atlantique department of the Pays de la Loire region in France. It serves a population of 2,250 and is part of the municipal wastewater infrastructure for the commune. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,500 m³/day and a current discharge volume of 401.40 m³/day, the facility operates well within its capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Atlantic Ocean via the Loire River basin. The plant's advanced treatment helps protect the downstream aquatic environment, including sensitive areas that support diverse freshwater and estuarine ecosystems.

The plant discharges into the local watershed, which is part of the larger Loire River basin. The Loire flows into the Atlantic Ocean, supporting diverse aquatic life and important migratory fish species. The advanced treatment ensures minimal nutrient and pollutant loading, protecting downstream water quality and ecological health.
