$100 million project involving 4.12 km-long x 4.12 m i.d. North Dorchester Bay and 830 m-long x 4.12 m i.d. Reserved Channel CSO consolidation conduits to be constructed mainly in glacial outwash sands and Boston Blue Clay at depths of 8 m to 17.5 m for MWRA. Tunnels to be constructed from large diameter shafts and connections with existing CSO outfalls to be made by drop shafts. Visit www.pbworld.com August 2000.The Massachusetts Water Resources Authority approved a USD300 million project which includes a 3.4 km 5.2 m-diameter tunnel near the shoreline in Dorchester and south Boston to collect the mix of storm water and sewage and hold it for processing. It also includes an odour control station at Carson Beach and a pumping station to be built at Conley Terminal in south Boston. If approved by state environmental officials, the project plans a "Little Dig" under Day Boulevard and Columbia Road, with a TBM burrowing the tunnel through soft ground. The tunnel is expected to start processing water when the station is completed in 2011. The plan is designed to close a gap in the USD4.5 billion Boston Harbour cleanup. Rain can overwhelm the city's combined system of storm drains and sewers, pushing untreated waste straight into the harbour. Visit www.mwra.state.ma.us 17/04.The Massachusetts Water Resources Authority (MWRA) on 19th July, 2006 awarded a USD145.7 million contract for the construction of a 5.2 m-diameter, 3,380 m-long tunnel in South Boston that will virtually eliminate combined sewer overflows (CSOs) and stormwater discharges to the beaches in South Boston. The contractor, a joint venture of Shank / Balfour Beatty / Barletta, will construct the North Dorchester Bay CSO storage tunnel in soft ground using a pressurized face TBM. The work will include a mining shaft at the downstream end of the tunnel, an equipment removal shaft at the upstream end of the tunnel, six intermediate drop shafts at the existing CSO outfalls, CSO and stormwater diversion and odour control structures, and associated shallow piping and utility conduits. The tunnel is expected to be completed in 2009.

Water

5.7 km-long x 2.9 m horseshoe-section Claremont tunnel constructed in 1928 to be emptied and inspected in January, 2001 with a view to designing a seismic improvement programme through the actively creeping portion of the Hayward Fault zone. Project leader Jacobs Associates with Camp, Dresser & McKee, Geomatrix, and Earthquake & Structure Inc. Visit www.jacobssf.com July 2000.The San Francisco Public Utilities Commission (SFPUC) selected URS and Jacobs Associates to design the new Irvington tunnel. The 24-month design phase began in August 2006, and the project construction should reach completion in 2013. The existing Irvington tunnel connects the Alameda siphons in the Sunol Valley to the Bay Division Pipelines in Fremont. This 3 m-diameter tunnel runs approximately 5.6 kilometres between two active faults, the Hayward and Calaveras. Approximately 85% of SFPUC water would not reach the San Francisco Bay Area if the current Irvington tunnel ever failed due to an earthquake or other reasons. Built around 1930, it last saw an inspection in 1966. The SFPUC cannot take it out of service without impacting the water supply. The new Irvington tunnel, of a similar size and length, will lie just south of the existing tunnel. Facilities include the new tunnel with initial and final linings, overflow shaft, tunnel portals, and related ancillary appurtenances. The project, estimated to cost approximately USD120 million, likely will use TBM as the preferred excavation method, and a precast concrete segmental lining system.
