Fleury is a community in the Oise department in the North-West of Paris (France). The municipality required a greenfield 12,700 PE treatment capacity to treat the sewage water from 14 municipalities situated around Fleury. The site’s operator, Syndicat Mixte d’Assainissement des Sablons, required 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.
Sources, an independent company founded 18 years ago, has the capability to design very large water treatment facilities and plants from 1,000 PE to 600,000 PE, for both wastewater treatment and drinking water production. Sources is currently managing more than 25 construction sites every year. Nereda’s innovative technology appealed to Sources, thanks to its treatment abilities and its low operational expenditure. This process has led to a partnership between the Dutch innovation company Royal HaskoningDHV and French firm Sources to introduce a very compact and integrated solution for the wastewater treatment in France. The Nereda technology perfectly meets Fleury’s expectations. The award-winning Nereda wastewater solution is already being applied on five continents for municipal and industrial water. It purifies wastewater, cost-effectively and without chemicals, by deploying patented granular sludge technology.
Sources has local knowledge, through its network of five agencies throughout France, and also has a presence in Maghreb. The combination of both companies’ expertise and Sources’ local knowledge and presence makes the venture ideally placed to deliver Nereda technology to the region.
Three Nereda reactors have been designed to treat the peak flow of 144 m³/hour and meet Fleury’s effluent requirements. The completed layout minimises the plant’s impact on the rural landscape, with the incorporation of a green roof and an architecture that blends in sympathetically with the surrounding countryside environment.
This wastewater treatment project is the partners’ first Nereda project in France. Sources can now expand the deployment of Nereda technology in further wastewater treatment projects across France, ensuring excellent and sustainable treatment, and reduced pollution.
