The Hong Kong SAR Government’s Water Supplies Department (WSD) is charged with the responsibility of monitoring and maintaining reliable and adequate water supplies. Local yield collected in catchment areas with the 17 impounding reservoirs accounts for about 20% to 30% of Hong Kong’s total fresh water consumption. The major proportion of our fresh water supply comes from Dongjiang in the southern part of Mainland China. Both the collected local yield and the imported Dongjiang water are subject to stringent treatment and monitoring in order that the quality of treated water meets the Guidelines for Drinking- water Quality published by the World Health Organization (WHO Guidelines). Moreover, since the 1950s, we have taken full advantage of Hong Kong’s geographic proximity to the South China Sea to adopt sea water for flushing purposes. Fresh water and sea water are supplied through two entirely separate waterworks infrastructure systems. The water supplies are maintained in an extensive array of service reservoirs and water mains for distribution to homes and commercial developments. To ensure that Hong Kong’s water supplies remain secure, we make concerted efforts to exploit new water sources by introducing advanced technologies such as desalination, water reclamation, grey water recycling and rainwater harvesting. These six water sources will become the pillars that support Hong Kong with enhanced water security and ability to adapt to climate change. As one of the largest energy consumers in Hong Kong, WSD has also implemented measures to reduce our energy footprint through the development of viable renewable energy sources. Moreover, we are the first government department to be awarded the ISO 50001 Energy Management System certification. Our vision is to meet our customers’ expectations in providing quality water supply services. With this in mind, WSD’s committed workforce has adopted customer-oriented approach to ensure that our customers receive the most effective and high quality services.
