Substation Flood Proofing

As part of a resiliency initiative for a large utility provider in Northeast Illinois, V3 has performed flood mitigation feasibility studies for over a dozen impacted stations and substations. V3 also designed and permitted flood proofing modifications for two substations located within the floodway/floodplain associated with the East Branch DuPage River. To minimize subsurface utility conflicts, the design included a precast concrete block wall system wrapped with an impermeable ethylene propylene diene monomer liner. Other aspects of the design included ingress/egress openings equipped with a removable flood plank system and a pump station to handle interior drainage.
