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，加上大灣區 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）。 我們將繼續按照經修訂「全面水資源管理策略」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 updated Total Water Management Strategy, 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 nonpotable uses will account for the remaining 25% consumption. 二零一八至二零二二年全年食水供應 Annual Quantity of Fresh Water Supply 2018 - 2022 東江水 Dongjiang Water 本地集水 Yield from Hong Kong’s Catchments 二零一八至二零二二年全年日均用量（食水及海水） Total Average Daily Water Consumption (Fresh Water and Salt Water) 2018 - 2022 4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0.0 食水 Fresh Water 海水 Salt Water 百萬立方米 million m3 年份 Year 2022 2018 2019 2020 2021 0.87 2.92 3.79 0.88 2.89 3.77 0.87 2.81 3.68 3.54 0.76 2.78 0.84 2.73 3.57 1 200 1 000 800 600 400 200 0 百萬立方米 million m3 年份 Year 2022 2018 2019 2020 2021 277 736 1 013 278 718 996 225 802 1 027 244 811 1 055 256 810 1 066 水務署 二零二二至二三年年報 WSD Annual Report 2022/23 22 Scale up 升 級 開 拓
