We seek to build a diversified portfolio of water resources in the future. Fresh water resources will account for about 75% of the total water consumption in Hong Kong while the lower grade water for non-potable uses will account for the remaining 25% consumption. 食水 Fresh Water 海水 Salt Water 50 水務署 二零二三至二四年年報 WSD Annual Report 2023/24 Enhance 提升 Menu 目錄
