DWSD Cancels Upper Rouge Tunnel Contract

The Detroit Free Press (here) and Environment News Service Newswire (here) report that on May 29, 2009, the City of Detroit (DWSD) canceled the contract for the Upper Rouge Tunnel CSO project.

"The tunnel was designed to be 30 feet in diameter. It would have run parallel the Rouge River, mostly under park space, 160 feet below ground from Pembroke Avenue and Berg to Warren Avenue and West Outer Drive. The tunnel was intended to cut the frequency of overflow events from about 50 a year to fewer than one a year, reducing the overflow from an average of 1.3 billion gallons to 250 million gallons annually."
