JOUY 28 Wastewater Treatment Plant, Jouy, Centre-Val de Loire

JOUY 28 is a municipal wastewater treatment plant located in Jouy, a commune in the Eure-et-Loir department of the Centre-Val de Loire region, France. The plant serves a population of approximately 2,310 residents, classifying it as a small agglomeration under French and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,700 m³/day and a current discharge volume of 412.10 m³/day, the plant operates well within its capacity, ensuring effective treatment of incoming wastewater. The treated effluent is discharged into local watercourses that ultimately drain into the Eure River, a tributary of the Seine. The Seine basin supports diverse aquatic life and is a critical water resource for the region. The plant's advanced treatment helps protect downstream water quality and the ecological health of the Seine estuary.

The plant discharges into the Eure River basin, which flows into the Seine River and eventually the English Channel. The Seine estuary is an ecologically sensitive area that supports migratory fish species and diverse bird populations. Advanced treatment at JOUY 28 reduces nutrient loads, helping to prevent eutrophication in downstream waters.
