About

Water supply is an indispensable part of the livelihood of the people of Hong Kong and critical to the territory's sustainable developments. WSD has the mission to provide reliable and quality services of water supplies to a population of about 7.5 million. To ensure the sustainability of Hong Kong’s water supplies, in 2019 we reviewed the Total Water Management Strategy implemented since 2008 and updated it to adopt a two-pronged approach with emphasis on managing fresh water demands and building resilience in the fresh water supply to prepare anticipatively for the extreme effects of climate change with diversified water resources. We aim at reducing the per capita freshwater consumption by 10 per cent by 2030 (using 2016 as the base year) by taking forward a host of water demand management measures through water conservation, water loss management in both government and private water mains, and more use of lower grade water, including seawater and recycled water, for non-potable purposes. To build resilience in the fresh water supply, we commenced the construction of the first stage of the Tseung Kwan O Desalination Plant in December 2019, which uses the latest reverse osmosis technology to produce fresh water. Its first stage can meet approximately 5 per cent of Hong Kong's total freshwater consumption. While providing drinking water in full compliance with the Hong Kong Drinking Water Standards, we will continue to take forward the Action Plan for Enhancing Drinking Water Safety in Hong Kong, launched on 21 September 2017, to further enhance the drinking water safety at consumers’ taps. In addition, we launched the Water Safety Plan Subsidy Scheme on 13 July 2020 to encourage property owners and management agents of private residential or composite buildings to implement the Water Safety Plan for Buildings so as to effectively manage water safety risks in their buildings.
