The Dugway Storage Tunnel is 4.5km long, with a diameter of 8m. The contract also envisages the construction of six shafts of varying diameters and depths, connections between the tunnel and the shafts and a series of concrete structures for the collection and transporting of wastewater and rainwater.

The project is part of a broader plan for the collection, storage and treatment of these waters, with the objective of reducing the level of environmental pollution in Lake Erie.

The client, Northeast Ohio Regional Sewer District, is a government agency that manages the collection and treatment plants and infrastructures operating in the Cleveland Metropolitan Area.
