Dugway Storage Tunnel

The Northeast Ohio Regional Sewer District negotiated with the Environmental Protection Agency an overall Program to reduce raw sewage discharges to the environment. Known as a consent decree, the agreement outlines specific projects and milestones that will reduce those discharges from 4.5 billion gallons (17 billion litres) annually to 494 million gallons (1,870 million litres) during an overall period of 25 years.

Several tunnels, ranging from 2 to 5 miles (3.2 to 8.0 km) in length, up to 300 feet (91.4 m) underground and up to 24 feet (7.3 m) in diameter are part of this program. There are No. 5 remaining tunnel projects which are: the Dugway Tunnel, Shoreline Tunnel, Southerly Tunnel, Big Creek Tunnel and the Westerly Tunnel.

The Dugway Storage Tunnel (DST) is a combined sewer overflow deep tunnel project that will provide additional storage of combined sewer flows during wet weather events reducing the number of combined sewer discharges into the environment.

The project includes the construction of the following elements:

•14,840 LF (4,523 m) of 24 ft. (7.3 m) diameter tunnel

•Six deep shafts

•Adit connections between shafts and tunnel

Consolidated Structures

•Near surface structures

•Site/civil restoration

•Modifications to existing regulatory structures.
