Hong Kong is one of the most densely populated regions that is experiencing stresses on its water resources. The Water Supply Department (WSD) of Hong Kong has initiated a Total Water Management strategy to manage demand and supply. As part of this effort, it is implementing a seawater desalination plant with 135 MLD capacity, expandable to 270 MLD. The plant has a submerged open intake, DAF, 2 pass RO to meet stringent bromide levels, post-treatment with lime and CO2 and on-site chlorine generation. The facility is procured under a Design Build Operate method, with transfer to the WSD to continue operations. The presentation will discuss planning, environmental issues and water quality results after blending with other sources.
