HATS Hong Kong
LNS has acquired, in a Joint Venture with Leighton Asia (Leighton), a contract amounting to approximately 2.1 billion kroner for a sewage tunnel in Hong Kong. The principal delegating authority for this contract is the Hong Kong Drainage Service Department.
The part of the HATS project that was awarded to the Leighton-LNS Joint Venture is marked on the map in red.
This contract includes a sewage exchange tunnel from Aberdeen to Sai Ying Pun on Hong Kong Island. The project is part of the Hong Kong Government’s Harbour Area Treatment Scheme (HATS), a world-class sewage treatment project. When the project is finished the harbour basin in Hong Kong will be much cleaner and healthier. The contract includes project planning and driving of 7.5 km tunnel. Furthermore, 5 shafts with lengths from 70 to 120 meters will be constructed. Inside the tunnel, 2 oval pipes with diameters from 1.38 m to 1.65 m shall be cast. About 140 000 m3 of concrete will be used all together. The tunnel is partly below the sea and runs partly below buildings in Hong Kong.
The project will start in August 2009, and should be finished in October 2013.
The greatest challenge to this project is driving the tunnel below the large urban city. Very strict requirements have been set for sealing and water tightness of the tunnel.
