Scope Of Work
Construction Support Solutions partnered with the Northeast Ohio Regional Sewer District (NEORSD) to install a 24-ft diameter storage tunnel approximately 15,000 feet in length, extending from the Euclid Creek Tunnel at the Nine Mile Site to its terminus near Superior Avenue and Lakeview Road in Cleveland.
The tunnel will be constructed with a tunnel boring machine in Chagrin Shale at depths approaching 200 feet below ground level. The project will also include several consolidation sewers, diversion structures and drop shafts to capture and store combined sewer overflow (CSO) from the Dugway Storage Tunnel service area. The diversion systems will be equipped with inflow control gates to manage the dynamic flow within the tunnel system.
