  1. Why we need desalination plant in Hong Kong?
    Due to population and economic growth in Hong Kong together with the impact of climate changes, it is time to explore strategic water sources for the stable water supply in Hong Kong. Seawater desalination is one of them.
  2. Why the desalination plant is located at Tseung Kwan O Area 137?
    Tseung Kwan O Area 137 is selected because the seawater quality in the area is suitable, its location is close to the strategic water supply network, and the resulted environmental impact is insignificant.
  3. How does the seawater get in and out of Tseung Kwan O Desalination Plant?
    The sea water inlet will follow the environmental protection design and carefully control the flow rate of the water inlet. The reverse osmosis concentrated brine will be discharged at the submarine drain, and a diffuser is used to promote the rapid dilution of the concentrated brine after it is discharged. Sea water quality monitoring and auditing can ensure that coral communities and marine ecology will not be unacceptably affected.
  4. What is Reverse Osmosis?
    Reverse Osmosis is a process of applying excessive pressure to force water from the brine water through a semi-permeable membrane to the fresh water side (Desalination).
  5. Is the taste and odour of desalinated water different from the normal drinking water?
    There is no taste and odour in the desalinated water. The taste will not be different from the current drinking water.
