Overview
JUZIERS wastewater treatment plant in Juziers, Île-de-France, France, serves a population of 1,966 with advanced treatment. It discharges 350.73 m³/day and has a designed capacity of 4,000 m³/day.
The JUZIERS wastewater treatment plant is located in Juziers, a commune in the Yvelines department of Île-de-France, France. It serves a population of approximately 1,966 people, making it a small agglomeration under French and EU classifications. The plant is situated along the Seine River, which is the primary waterway in the region. 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 4,000 m³/day and currently discharges an average of 350.73 m³/day, indicating significant spare capacity. The treated effluent is discharged into the Seine River, which flows through Paris and eventually into the English Channel via the Seine estuary. The Seine basin supports diverse aquatic life and is a critical water resource for the region. The plant's advanced treatment helps reduce nutrient loading, contributing to the ecological health of the Seine and its downstream environments.
Environmental context
The JUZIERS plant discharges into the Seine River, which flows northwest through Île-de-France and Normandy before reaching the English Channel at Le Havre. The Seine estuary is an ecologically sensitive area that supports migratory fish species and diverse bird populations. Advanced treatment at this plant helps minimize nutrient pollution, protecting downstream water quality and the marine environment.
