The Upper Rouge tunnel is designed to mitigate and control the combined sewer overflows (CSOs) from 17 outfalls in Detroit, three outfalls in Dearborn Heights and eight outfalls in Redford Township and provide a facility to capture and store these CSOs to the Upper Rouge river during wet weather events. The project will be divided into eight construction contracts: two tunnel contracts (south and north tunnels), five near surface facility contracts, and one pump station contract. The DWSD completed the design in December 2007. The tunnel system includes an 11.28 km 9.14 m ID tunnel, a 24.4 m ID pump station, two work shafts about 15.2 m ID each and 14 drop shafts with various IDs. At about 50 metres below ground level, the tunnel passes through three geologic formations: Antrim shale, Travers Group, and Dundee limestone. Presence of toxic and explosive gases like hydrogen sulfide and methane gases and artesin groundwater conditions can be expected during tunnelling. The tunnel will be built by TBM. The north tunnel will be tendered separately and built between March 2009 and July 2013. 13/08.
