West Kowloon Drainage Improvement - Lai Chi Kok Drainage Tunnel

Project Scope

The scope of the project comprises the construction of drainage tunnels of 3.7km long and 4.9m in diameter, 6 intake structures along Ching Cheung Road and Tai Po Road, a stilling basin at the former Wai Man Tsuen and an outfall near Stonecutters Island.

The drainage tunnels are deep into the ground from Chak On Estate via stilling basin at the former Wai Man Tsuen to Victoria harbour near Stonecutters Island to intercept and convey the stormwater from the upper catchments directly to the sea near Stonecutters Island

Major Improvements and Benefits
Upon completion of the works, rainwater from the upper catchments of Sham Shui Po, Cheung Sha Wan and Lai Chi Kok will be intercepted by the drainage tunnel and hence the capacity of the existing stormwater drainage system will be improved.
