3 300立方米的重用中水。該項目憑藉創意，以原地重用中水的 方式節省了由遠處輸送沖廁水至該位處地勢較高的發展項目所需 的耗電，獲頒二零二一年英國土木工程師學會 Chris Binnie 可持 續水務管理大獎。我們計劃進一步擴大循環再用水的應用範圍至 所有新發展區和合適的大規模重建區，以期提升海水和循環再用 水的供應網絡覆蓋率，由目前佔香港總人口的85%至長遠目標 90%。 at the Anderson Road Quarry Site Development capable of supplying 3 300 m3 of treated grey water daily to the Development by 2024. This grey water reuse project was awarded the Institution of Civil Engineers Award 2021 – Chris Binnie Award for Sustainable Water Management for its creativity in reusing treated grey water on-site to save the energy required for pumping flushing water from afar to the Development at high altitude. We plan to further extend the use of recycled water in all New Development Areas and suitable large scale redevelopment areas with a view to increasing the coverage of the salt water and recycled water supply networks from the current 85% of the total population to 90% in the long run. 實現更有效率和可持續的資產管理 藉著創意和科技發展，我們力求以更有效率和可持續的方式管理 水務資產，並充分考慮公眾安全、社會需求和減碳目標。 為提升運作效率，我們正積極為濾水廠及供水管網建立「數碼分 身」。「數碼分身」是真實系統的虛擬代表，能透過人工智能技術 持續監測和分析運作數據，從而模擬和預測系統的運作，以協助 我們發現潛在問題、優化系統運作、減少用水流失和耗能。作為 水務設施運作自動化轉型的第一步，我們展開了先導計劃，試行 在夜更遙距操作深井濾水廠。此外，我們正籌備於二零二五年成 立先進的中央運作管理中心聯網，以加強實時遙距監測、協調和 事故管理。 我們亦致力優化資產的運用，以市民的福祉為依歸。我們為 12 間主要濾水廠安裝現場氯氣生產設施，設施可按需要在現場 生產氯氣作食水消毒之用。此安排可消除在運輸和貯存液體氯過 程中洩漏氯氣的風險，亦可確保氯氣供應維持穩定。如此廣泛應 用該技術於食水消毒為全球首例。因應社會對土地的需求，我們 正籌劃將濾水廠和配水庫遷往岩洞，以騰出珍貴的土地資源作建 屋和其他有利民生的用途。鑽石山配水庫遷往岩洞的建造工程將 於二零二二年尾展開，而其他岩洞發展項目的可行性研究/ 勘查 研究亦正進行中，涉及面積共約30公頃。 STRIVING FOR MORE EFFICIENT AND SUSTAINABLE ASSET MANAGEMENT Pivoting innovation as well as technological advancement, we seek to manage our waterworks assets more efficiently and in a sustainable manner with due consideration to public safety, society 's needs and decarbonisation target. We are actively developing digital twins of water treatment works and water supply networks to enhance our operation efficiency. Digital twin is a virtual representation of the real system which can simulate and predict the system operations through continuous monitoring and analysis of operational data with artificial intelligence. This will greatly facilitate us to anticipate potential problems, optimise system operations, reduce water losses and energy consumption. As our first step to transform the operation of waterworks installations towards automation, we have embarked on a trial project to enable remote operation on the night shift at the Sham Tseng Water Treatment Works (WTW). We are also planning the establishment of a cluster of advanced centralised operation management centres by 2025 to enhance real-time remote monitoring, coordination and incident management. We also strive to optimise the utilisation of our assets for the benefits of the public. We are installing on-site chlorine generation facilities at 12 major WTWs to produce chlorine on demand for drinking water disinfection. This arrangement eliminates the risks of chlorine leakage during the transportation and storage of liquid chlorine, and ensures a reliable supply of chlorine gas. Such extensive application of the technology in drinking water disinfection is the first of its kind in the world. In response to the society’s needs for land, we are making plans of relocating WTWs and service reservoirs to caverns to release precious land resources for housing and other beneficial uses. The construction works for the relocation of the Diamond Hill Service Reservoirs to cavern will commence by end 2022. The feasibility studies / investigation of other cavern development projects are underway which will involve areas totalling some 30 hectares. 水務署 二零二一至二二年年報 WSD Annual Report 2021/22 7 署長的話 Director’ s Statement
