Stonecutters Island HATS 2A
Tunneling and water treatment
In conjunction with local partner Chun Wo Development Holdings Ltd., CEC won the Stonecutters Island contract portion of the Hong Kong government’s Harbor Area Treatment Scheme , Stage 2A (HATS 2A). The scope of work included the construction of an effluent tunnel and disinfection facilities in Kowloon. The teams constructed an 880 m effluent tunnel with an internal diameter of 8.5 m at 95 m below ground level using the drill-and-blast method. The tunnel plays a key role in connecting disinfection facilities with other work facilities and the project set a milestone of CEC’s expertise in environmental engineering related work in Hong Kong.
