Indianapolis, IN

This project is part of Citizen Energy Group’s Tunnel program directing wet weather flow from combined sewers to tunnels to prevent untreated water from entering the waterways.

Construction included providing cast-in-place structures at the Fall Creek Combined Consolidation Sewer (CCS) Phase I project that conveys flow to the drop shafts for the tunnel. Wilhelm installed all sanitary diversion structures, access holes and pipe beneath 28th Street. Storm pipe structures as well as road and sidewalk restoration are also part of the project’s scope. Earth retention for excavation equipment, dewatering and traffic control are all key considerations in this project’s success.
