The scope of the project comprises the construction of a water tunnel, approximately 2.8 km in length and 3 m in diameter, and the associated intake and outfall structures at both ends of the tunnel. The geology of the area basically comprises of mainly granite. At the portal, contractors will make use of conventional mechanical excavation (hydraulic hammer and backhoe). The main tunnel will be built by a tunnel boring machine. The temporary support depends on rock mass quality (envisaged support may include rock bolts, welded wire mesh, steel arches and/or shotcrete). As permanent support lining, the tunnel may be partly unlined subject to development of hydraulic design but permanent rock bolts will be anchored in unlined portions whereas in lined portions, cast in-situ lining or shotcrete will be preferred (with adequate finish for optimal hydraulic roughness). In the main tunnel, a conveyor belt or mining train with wagons will be used to transport the rock away. The project is still in preliminary design and bids for construction are expected to be invited in July 2009. Work is scheduled to start in December 2009 for completion in April 2012. The cost of the tunnel is HKD220 million. Contact Water Supplies Department, Hong Kong, tel. +852 28294798, fax +852 25861696, e-mail Ricky Wong Kin San ricky_ks_wong@wsd.gov.hk.
