Rye Brook, N.Y./USA, Paris/France – Xylem will supply the pumps and related accessories to recirculate water and sludge through basins and feed the facility’s biological tanks with wastewater.

The Achères Seine Aval wastewater treatment plant treats about 1.5 million cubic meters of wastewater in the Paris region every day. Service Public de L’assainissement Francilien (SIAAP), the municipal authority that manages the city’s urban wastewater treatment facilities, has undertaken a development program to expand the existing biofiltration units and build a new membrane treatment line in the plant.

The modernization of the system is necessary to meet the requirements of the European Water Directives which set objectives and standards for future water protection in Europe. The upgraded technology will contribute to maintaining the water quality of the Seine River as well as increasing the treatment efficiency of the plant. The project is due to be completed by 2021.

“We have been working with Xylem for several decades so we are well aware of their water and wastewater expertise and the quality of their technology,” said Gaël Brion, project director for the consortium responsible for overseeing the development project. “It is important for us to be able to provide our customers with energy-efficient technologies and to reduce the operating costs of the plant. The majority of pumps we are using incorporate Flygt’s N-technology which prevents clogging and enables sustained high efficiency, helping to minimize energy consumption.”

The first deliveries of Flygt pumps and controls will begin in March 2015 and the upgrade works are due to be completed by July 2018.
