With continuous urbanization and development in Lai Chi Kok, Sham Shui Po and Cheung Sha Wan, the capacity of existing drainage system was no longer adequate to cope with the increasing flows during times of heavy rainstorms and floodings was found at the costal urban areas.  The construction of Lai Chi Kok Drainage Tunnel (LCKDT) was commenced in November 2008 and it was commissioned in October 2012.


LCKDT adopted an interception approach which six intakes are constructed along Northern side of Ching Cheung Road to intercept stormwater flow.  The intercepted flow is then diverted to the stilling basin via the branch tunnel and then further discharge to the harbor via the main tunnel.


Tunnel interception approach is an innovative flood relief measure.  The construction work sites are located in rural areas such that extensive road openings can be avoided and minimize the disturbances to the public, traffic, and commercial activities and at the same time achieving the flood relief purpose.


The 3.7km tunnel is consisted of a 2.5km long “branch tunnel” constructed at the mid-level along Ching Cheung Road and a 1.2km long “main tunnel” underlying below Lai Chi Kok urban area.  A stilling basin is located in between the two tunnels and the outfall is located at Stonecutters Island.


In this event, the representative of the DSD will brief our members the basic concept and operation of the LCKDT.  A tour of different areas of the LCKDT will also be arranged.
