BAZEMONT NEZEL is a municipal wastewater treatment plant located in Nézel, a commune in the Yvelines department of Île-de-France, France. The plant serves a population of approximately 3,947 people, classifying it as a small agglomeration under French and EU regulations. Its designed capacity is 3,500 m³/day, with a reported discharge volume of 704.14 m³/day. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant operates under the French regulatory framework, which implements the EU directive through national legislation, and is subject to permits issued by the local water agency. The treated effluent is discharged into a local watercourse that eventually flows into the Seine River basin. The Seine River drains into the English Channel, impacting the marine environment of the Baie de Seine. The plant's operation helps protect the local watershed from nutrient pollution and supports the ecological health of downstream water bodies.
Environmental context
The plant discharges into a tributary of the Seine River, which flows through the Paris Basin and ultimately reaches the English Channel. The Seine estuary and Baie de Seine are ecologically sensitive areas that support diverse aquatic life, including migratory fish species. Nutrient loading from wastewater can contribute to eutrophication in coastal waters, making effective treatment crucial for maintaining water quality in this densely populated region.
