Legislative Control of Water Quality

The Water Pollution Control Ordinance, enacted in 1980, is the main legislation to control water pollution in Hong Kong. The ordinance and its subsidiary legislation allow the Government to declare Hong Kong waters into ten water control zones (WCZs). Control of discharges in these zones to achieve and maintain water quality objectives is exercised mainly through a licensing system. The first water control zone was "Tolo Harbour and Channel Water Control Zone" which commenced on 1 April 1987. The rest of Hong Kong waters were progressively brought under legislative control over the next 12 years.

The last two WCZs to be declared were "Second Southern Supplementary WCZ" and "North Western Supplementary WCZ" and their commencement dates were the same, i.e. 1 November 1999. Additional provisions on water quality management are also contained in other pieces of legislation. This body of environmental legislation will ensure that sewage and industrial wastewater will be discharged in an environmentally acceptable manner.

Amendment of Water Pollution Control Ordinance

The Water Pollution Control Ordinance enacted in 1980 enables the Government to set up water control zones in which regulations are applied to control effluent discharges with the aim of achieving water quality objectives in each zone. It was amended in 1990 to expand the scope and allow for tighter controls on effluent discharge. Further amendments were made in 1993 to impose controls on the connection of wastewater to the public sewerage system and the proper operation and maintenance of private communal sewage treatment plants.
