提升食水供應的應變力 海水化淡 為應對氣候變化對本地集水帶來的極端影響，我們正發展海水 化淡這種策略性的水資源，興建將軍澳海水化淡廠第一期，以 加強香港食水供應的應變能力。 將軍澳海水化淡廠採用先進的逆滲透技術，生產的食水符合香 港食水標準。該廠計劃於二零二三年年底投產，第一期項目的 年產量為5 000 萬立方米，未來更可擴展至每年 1 億立方米。 作為具氣候抵禦力的頂級水務設施，可持續的環保特色已融入 於化淡廠的設計、建造和保養工作中，包括採用可再生能源和 低耗能工序、雨水回收作灌溉用途、智慧燈柱、屋頂和牆身的 綠化，務求將碳足跡減至最低，並提升能源效益。我們亦計劃 於新界東南堆填區建造大型太陽能發電場，為將軍澳海水化淡 廠供應可再生能源。 根據香港綠色建築議會的暫定評估，將軍澳海水淡化廠的第一 期項目已獲得綠建環評（新建建築類別）的「暫定鉑金級」。 BUILDING RESILIENCE IN FRESH WATER SUPPLY Seawater Desalination To cope with the extreme impacts of climate change on the local yield, the WSD is developing a strategic fresh water resource — desalination and building the first stage of the Tseung Kwan O Desalination Plant to strengthen resilience for the fresh water supply in Hong Kong. Using the latest reverse osmosis technology, the Tseung Kwan O Desalination Plant will produce potable water in compliance with the “Hong Kong Drinking Water Standards”. Scheduled to start commissioning in end 2023, the first stage of the Desalination Plant will have a production capacity of 50 million m3 per year with the provision to double its capacity to 100 million m3 per year in the future. As a top-class, climate-proof waterworks infrastructure, sustainable and green features are integrated into the design, construction and maintenance of the plant. These include the adoption of renewable energies and low-energy consumption processes, rainwater harvesting for irrigation, smart street lighting poles, green roofs and walls to minimise carbon footprint while enhancing energy efficiency. We are also planning a large-scale solar farm at the South East New Territories Landfill for supplying renewable energy to the Tseung Kwan O Desalination Plant. Based on the Provisional Assessment by Hong Kong Green Building Council (HKGBC), the first stage of Tseung Kwan O Desalination Plant project has achieved the “Provisional Platinum” rating under the BEAM Plus (New Buildings Category). 將軍澳海水淡化廠第一 期項目可帶來可靠的食水水源，同時將可持 續和環保特色融入化淡廠的設計、建造和保養工作中。 The first stage of Tseung Kwan O Desalination Plant will produce a reliable source of potable water while integrating sustainable and green features into the design, construction and maintenance of the plant. 水務署 二零二二至二三年年報 WSD Annual Report 2022/23 39 Scale up 升 級 開 拓
