Inter-reservoirs Transfer Scheme – Water Tunnel between Kowloon Byewash Reservoir and Lower Shing Mun Reservoir

Current Project

Bouygues Travaux Publics will construct a tunnel of approximately 2.8km long with a 3-metre diameter from the Kowloon Byewash Reservoir to the Lower Shing Mun Reservoir, and the associated intake and outfall structures at both ends of the tunnel. When completed in 2022, the tunnel will serve dual objectives of improving flood protection level in West Kowloon areas and optimising water conservation, by transferring collected surface runoff from the Kowloon group of reservoirs to the Lower Shing Mun Reservoir. In the long run, this tunnel will strengthen the city’s resilience in flood mitigation to combat climate change.

The worksite locates at the tranquil Kam Shan Country Park. Meticulous project planning will be executing to ensure a smooth flow of all construction activities, also to conserve the precious natural environment.
