Deep Sewer
Two large tunnels at depths of 20 m to 50 m. Value $5.2 billion. October 1998.
Concept is to use link sewers to intercept flows from existing gravity sewers upstream of the existing pumping stations and channel them by gravity through deep tunnels to centralised STWs at the south coast and thence to discharge via deep sea outfalls. With up to 45 m water pressure, tunnels will be driven by EPB or slurry TBM with sealed, bolted, grouted precast concrete segmental lining. Final lining will be cast-in-place concrete with corrosion-resistant membrane.
North tunnel from Changi East to Kranji comprises five contracts. T-01 is for 5.9 km of 6.0 m i.d. tunnel with 5 shafts; T-02 is for 7.7 km of 6.0 m with 7 shafts and an odour control facility (OCF); T-03 for 5.2 km of 6.0 m with 10 shafts, 3 ODFs, and a 250 m lateral connector; T-04 is for 7.2 km of 4.3 m i.d. with 9 shafts, 2 ODFs, and an 800 m lateral connector; T-05 is for 12.5 km of 3.6 m i.d. with 11 shafts and one ODF. Eastern two-thirds of the North tunnel is in Old Alluvium, a competent tunnelling medium. Western one-third in granite.
Spur tunnel T-06 connecting Tanglin and Holland Road areas comprises 9.7 km of 3.3 m i.d. tunnel with 8 shafts. Alignment is in fractured sedimentary rock, dense soil and faulted ground requiring shielded TBM with hard and soft rock capability.
