sewage strategy.

As a result of this study the Hong Kong Government identified

a number of areas which require essential and particularly urgent

action. These form the High Priority Programme (HPP). The HPP

is estimated to cost HK$7.3 billion (1992 prices). Its

Government and will be completed in early 1997. On its

commissioning, the HPP will help curtail harbour pollution

significantly and should remove some 70% of the major pollutant

loads in the sewage discharges.

collection and treatment system and the improvement of six

regional sewage collection networks leading into it. The

principal collection and treatment system will be made up of a

deep tunnel system to collect all sewage from Chai Wan, Shau Kei
