Lille European Metropolis (Métropole Européenne de Lille (MEL), a French Public intermunicipal cooperation authority, manages the sanitation of the 95 municipalities in its territory.
The territory is divided into 17 sanitation agglomerations, the largest of which is Lille (533,333 population equivalent). In order to meet the regulatory obligations of the European “Urban Wastewater” Directive and the associated national regulations concerning the limitation of pollution discharges in rainy weather from combined sewage systems, MEL has included in its Local Urban Plan, since 2004, prescriptions concerning sustainable management of rainwater for urban development and urban renewal projects and is developing the disconnection of stormwater when requalifying public spaces.
At the same time, MEL has deployed storage basins to reduce its main discharges. In order to optimize its equipments, MEL is now turning to intelligent and dynamic management strategies. The LIFE RUBIES project is an innovative program that takes into account both hydraulic flows and pollution flows. MEL has therefore expressed its support to participate as a partner and user of the LIFE RUBIES proposal. Within the scope of the project, MEL provides strategic sites for a concrete experimentation.
