具氣候應變能力的供水新時代 隨著將軍澳海水化淡廠第一期在二零二三年十二月開始投產， 香港正式進入供水的新時代，從此我們擁有一個穩定且不受氣 候變化影響的新水源，實現本地供水保障的一項重要里程碑。 將軍澳海水化淡廠採用最先進的逆滲透海水化淡技術，所生產 的食水完全符合「香港食水標準」，每日食水產量為13.5 萬立 方米，並可在極端天氣下提供食水以應付市民最基本的日常需要。 安達臣道石礦場用地發展的中水處理廠是我們今年的另一個重 點項目。該中水處理廠將於二零二五年全面投入運作，屆時將 成為全港首個地區性中水重用系統，並為未來擴大循環再用水 作非飲用用途奠定基礎。這個系統不僅具備資源效益，同時優 化用水循環，節省食水資源，並顯著減少抽水過程中的能源消耗。 我們在促進多元化水資源方面也取得了良好的進展，在新發展 區已著手建造首個中央再造水供應系統。隨著石湖墟再造水廠 於二零二四年三月落成，為原本經處理的排放水進一步加工處 理，我們已開始向上水的用戶供應再造水作沖廁用途。餘下的 再造水供水系統建造工程將於二零二六年分階段完成。 上述建設為香港提供了三個全新的水源，大大提升了我們應對 降雨不穩定等極端氣候變化的應變能力，同時亦緩解了隨著香 港人口增長和創新科技帶動的經濟發展所引致的供水需求壓 力。 未來數年，為配合北部都會區的策略性增長，我們將積極 擴大使用次階水（即海水、再造水及經處理的中水），令其佔 總用水量的比例由目前的25%增加至30%，並在未來逐步擴 大應用範圍至區域供冷系統。 ENTERING A NEW ERA OF CLIMATE-RESILIENT WATER SUPPLIES With the commissioning of the first stage of Tseung Kwan O Desalination Plant (TKODP) in December 2023, Hong Kong has entered into a new era equipping with a stable water source that is not susceptible to climate change, which signifies a key milestone in enhancing water security. Using the state-of-the-art reverse osmosis desalination technology, the TKODP is producing potable water in compliance with the "Hong Kong Drinking Water Standards" with a production capacity of 135 000 m3 per day, thereby providing the public with an essential access to drinking water in times of extreme circumstances. Another notable milestone was the establishment of the Grey Water Treatment Plant at the Development of Anderson Road Quarry Site due to be fully operational by 2025. This has marked the first district-based grey water recycling system in Hong Kong, scaling up the reuse of recycled water for non-potable uses in the future. Promoting resource efficiency and circularity also saves our fresh water resources as well as energy consumption arising from pumping load. We have also made a good progress in diversifying water resources by developing the first-ever centralised reclaimed water supply system for new development areas. Following the completion of the new Shek Wu Hui Water Reclamation Plant for further processing the treated sewage effluents, we commenced the supply of reclaimed water for toilet flushing in Sheung Shui in March 2024. The remaining reclaimed water supply system will be completed in stages by 2026. These developments provide Hong Kong with three new water resources which have significantly enhanced our water resilience against intensifying climate impacts such as unstable rainfall patterns, as well as increasing water demand arising from growing population and Innovation & Technology driven economic growth in Hong Kong. In coming years, we aim to expand the use of lower grade water (namely seawater, reclaimed water and treated grey water) from the current 25% to 30% leveraging the strategic growth in the Northern Metropolis and widen its applications including district cooling system in the future.
