PILOT SCHEME TO INSTALL AIR DIFFUSERS IN KOWLOON BAY
An application has been made to include in the Public Works
Programme a pilot study of air diffusers in Kowloon Bay in an attempt to improve the water quality there.
In reply to a question by the Hon. Roger Lobo in the Legislative Council today, the Hon. James Robson, Secretary for the Environment, said: "It is hoped that this will be implemented during the 1976/77 financial
year."

The pilot scheme would involve the installation of 20 air diffusers
at a cost of about $300,000, Mr. Robson said. It was endorsed by the
dvisory Committee on Environmental Pollution.
technical report produced by the Public Works Department last
June stated that air diffusers fixed to the sea bottom would be the most
suitable method of improving water quality. These diffusers would bubble
air through the polluted water to increase levels of dissolved oxygen, thus
improving water quality and eliminating smells.
Preliminary investigations indicated that about 420 air diffusers
would probably be needed at a capital cost of $3.5 million, and an annually recurrent costs of $800,000.
