Victoria Harbour water to improve after sewage works upgrade
Marine eco-system to prosper as world's largest underground waste pumping station is built
Victoria Harbour's water quality is set to improve when the second stage of the Harbour Area Treatment Scheme reaches its halfway mark next year.
Hong Kong's famous landmark should see 90 per cent of the current Ecoli eliminated from discharged sewage.
During this stage of the project, the Drainage Services Department will upgrade the 10-hectare sewage treatment works on Stonecutters Island in West Kowloon by building the world's largest underground pumping station.
There will be eight pumps and each pump can process sewage equal to one standard swimming pool in 10 minutes.
A tunnel will connect it to the existing works to allow the diversion of the waste.
A new conveyance system will take the waste from eight preliminary treatment works on the north and south of Hong Kong Island to the upgraded Stonecutters Island works for sedimentation and disinfection via an underwater tunnel.
"We will see a cleaner Victoria Harbour, which will provide a better living environment for the marine ecosystem," said Henry Chau Kwok-ming, the department's chief engineer for the scheme.
