It is the solemn responsibility of the Hong Kong SAR Government’s Water Supplies Department to monitor and manage all facets of securing and maintaining fresh and salt water supplies throughout Hong Kong. Each day our Department supplies about 2.6 million cubic metres of fresh water to satisfy the needs of about 7.2 million residents. The fresh water supplies we rely on are drawn in part from Hong Kong’s vast hillside catchment installations along with a substantial amount of water that comes from Dongjiang in southern part of Mainland, which is subject to stringent treatment and monitoring in order to meet the latest international water quality standards. Afterwards all fresh water resources are kept in an extensive array of service reservoirs for distribution to homes and commercial developments. We also make prudent application of seawater, which is first treated and then sent along to supply toilet flushing systems. Seawater flushing is commonly found in most residential, commercial and industrial buildings in urban area and new towns of Hong Kong. This type of water resource is instrumental in helping us reduce our overall requirements for fresh water resources. The Department is also proactive in initiating and monitoring the development of new water sources through more advanced methodologies such as desalination, water reclamation, grey water recycling and rainwater harvesting.

Every day each WSD employee is dedicated to meeting the expectations and needs of Hong Kong customers while successfully implementing robust and effective policies and practices to help conserve our precious water resources. Water is an indispensable resource that serves as a cornerstone for the vitality and prosperity of Hong Kong. That is why we will continue to work in partnership with all stakeholders to optimise our supplies so that Hong Kong’s water remains secure and of high quality today and long into the future.
