About Fleury Nereda® WWTP – FranceFleury is in the Oise department in the North West of Paris, France.
The challengeFleury Wastewater Treatment Plant (WWTP) required an upgrade, to accommodate a 12,700 p.e. treatment capacity, to treat the wastewater from the 14 municipalities served by the plant. The site’s operator, Syndicat Mixte d’Assainissement des Sablons, sought a wastewater management provider to install a system that could cope with the population, but also minimise the environmental impact – a combination of efficiency, aesthetic and compactness.
After competitive tendering, Sources SA, an independent French company was selected to carry out the work. The innovative Nereda technology appealed to Sources, due to its treatment abilities and its low operational expenditure. This has led to a partnership between Royal HaskoningDHV and Sources to introduce a very compact and integrated solution for wastewater treatment in France. The Nereda technology perfectly meets Fleury’s requirements. The award-winning Nereda wastewater solution purifies wastewater cost-effectively and without chemicals, by deploying granular sludge technology.
Three Nereda reactors have been designed to treat the peak flow of 144 m³/hour and meet Fleury’s effluent requirements. The completed layout will minimise the plant’s impact on the rural landscape, with the incorporation of a green roof and an architectural design that blends in sympathetically with the surrounding countryside environment.
