Drainage Improvement in Northern Hong Kong Island – Hong Kong West Drainage Tunnel

Project Scope

The Project aims at alleviating the flooding problems in Northern Hong Kong lsland.
The scope of the project comprises the construction of a drainage tunnel deep into the ground in Mid-levels of the Northern Hong Kong Island from Tai Hang to Pokfulam to intercept and convey the stormwater from the upper catchment directly to the sea near Cyberport.

Major Improvements and Benefits
After completion of the works, rainwater above Mid-levels will be intercepted by the drainage tunnel and hence the capacity of the existing stormwater drainage system will be improved. Together with the lower catchment works to be implemented, a reasonable flood protection level can be achieved.
