Leighton Asia, India and Offshore designed and built two underground drainage tunnels in Hong Kong. They are part of a drainage system that captures rainwater in the north and discharges it into Victoria Harbour, with the aim of alleviating flooding in the low-lying, densely populated areas of Kowloon. The total length of the two tunnels is 3.7 kilometers, and each one measures nearly five meters in diameter. Construction of various intake shafts and connection adits, a stilling basin, and an outfall structure were also included in the CIMIC subsidiary’s contract. A tunnel boring machine (TBM) and blasting were the methods used to build the tunnels.
