Flooding Buildings

The CanaMarne project, which extends the drainage channel from the Renardières basin into the Marne river, should protect municipalities downstream from the Renardières basin from flooding by increasing the drainage flow Construction and infrastructure projects are systematically aligned with the "Rainwater Guidelines" Improving the robustness and redundancy of the network by modernising and reinforcing the power grid Studying the possibility of a new 225kVA power supply to increase the electrification of hubs The energy mix and redundancy ensure greater resilience of the electricity distribution system and continuity of operations Recent renovations to energy services (replacement of gas boilers, renewal of heat pumps, connection to the Dugny geothermal plant, renovation of electricity distribution networks, replacement of heating/ cooling meters) The construction standards adopted for the specific systems (SAS) mean that they are water-resistant, which limits the impact of the risk of flooding The mobility of many of these systems reduces the impact that flooding can have Renovating each runway structure every 25 to 30 years, making it possible to incorporate new construction materials (for better drainage, for example) Implementing a trajectory for reducing future waterproofing Projects are under way to improve rainwater management (drainage procedures, design standards for rainwater systems) Installation of a water drainage system and gradual replacement of ageing pipes with larger-diameter pipes Redundant transport systems offer alternative mobility solutions in the event of flooding Renewal of surface courses every 8 to 10 years, allowing the use of new, more permeable construction materials Implementation of the Airport Operations Centre (APOC), a supervision and decision-making centre whose role is to manage the airport's overall performance in real time. Its centralised management function, combined with the presence of operational control stations for the various processes, ensures the robustness and performance of operations through holistic decision-making and responsive implementation on the ground Renovation and resizing of drainage systems Revising the piezometric level Water drainage system to reduce the risk of overflows Renovation of drainage systems that began in 2022 Systematic replacement of ageing pipes with larger diameter pipes
