水資源未來的展望 氣候變化、人口和經濟持續增長令食水需求增加，以及大灣區 內對水資源的需求殷切等，皆為我們帶來挑戰。為了讓香港就 迎接這些挑戰做好準備，我們持續開發一些不受氣候變化影響 的新水源，包括淡化海水和循環再用水（即再造水、重用中水 及回收雨水）。 我們將繼續按照「策略2019」的建議，採取雙管齊下方式，為 未來建立多元化的水資源組合。食水資源將約佔香港總用水量 75%，而非飲用的次階水將佔其餘用水量25%。 Outlook of Future Water Resources To better prepare Hong Kong for the challenges of climate change, the increasing demand for fresh water due to its continuous population and economic growth, as well as the competition for water resources in the Greater Bay Area, we have been developing new water sources that are not susceptible to climate change, including desalinated water and recycled water (viz reclaimed water, treated grey water and harvested rainwater). Following the recommended two-pronged approach under the Strategy 2019, we seek to build a diversified portfolio of water resources in 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. 食水資源 Fresh water resources for potable use 75% 淡化海水 Desalinated water 東江水 Dongjiang water 本地集水 Local yield 根據「策略2019」預計的香港水資源組合 Estimated Composition of Hong Kong's Water Sources under Strategy 2019 次階水作非飲用用途 Lower grade water for non-potable use 香港總用水量 Total water consumption 5% 15-35% 60-80% 循環再用水 Recycle Water 海水 Salt Water 25% 現新 Innovate 水務署 二零二一至二二年年報 WSD Annual Report 2021/22 23
