NEWS: Dugway Storage Tunnel breakthrough is key Project Clean Lake milestone

Tunnel boring machine reaches her destination on March 21, 2018, completing her Dugway Storage Tunnel dig.

Dugway is the second of seven tunnel projects that will reduce Lake Erie pollution by 4 billion gallons a year


When the tunnel boring machine emerged from the shale near the stroke of midnight on March 21, 2018, it signaled the end of her journey but only a milestone on Project Clean Lake‘s map towards a cleaner Lake Erie.

The 14,000-foot-long, 24-foot-wide Dugway Storage Tunnel will continue being constructed over the next year, but the completion of mining operations is a significant achievement, said Director of Engineering & Construction Devona Marshall. “Large complex capital projects are not new for us,”she said. “But we see every project as an opportunity to be better. All of us — our employees and our contractors together — see Dugway [Storage Tunnel] as the latest example of that mindset.”

Project Clean Lake is a 25-year program, a combination of system and treatment plant construction and green infrastructure enhancements that scheduled from 2011 through 2036, that will reduce combined sewer overflows and improve water quality in the region. Once online in 2019, the Dugway Storage Tunnel will capture more than 370 million gallons of sewage and stormwater for treatment.
