Sustainable Réunion wastewater plant to use MF

Microfiltration will be used as part of a modern wastewater treatment plant on the island of Réunion to be built under a concession awarded by the Réunion North Interdistrict Community to a consortium led by Veolia Water.

The concession contract covers design, financing, construction and operation of the new plant at Grand Prado for a period of 20 years. The new plant will have an initial capacity of 160,000 population equivalent (pe), with the possibility of later extension to 235,000 pe.

The contract is worth estimated consolidated revenue of € 270 million for Veolia Water. Within the consortium, the engineering will be handled by OTV, a Veolia Water subsidiary which will lead the design and construction consortium and be in charge of equipment, with the exception of tertiary treatment, which has been awarded to Sogea.

The project will be a benchmark in terms of sustainable development on the island, as part of the “Green Reunion Island” project stemming from France’s Grenelle agreements: installation of solar panels on roofs to generate power, cogeneration of electricity using biogas from anaerobic digestion, a microfiltration unit to reuse part of the treated water for the plant’s internal needs and treatment of rainwater runoff by phytoremediation.
