管理用水流失 香港山多平地少，加上對地下水管的各樣頻密干擾，導致水管 滲漏的風險提高。為此，水務署實施下列措施，務求妥善管理 水管、優化供水系統網絡的運作表現、減少水管爆裂和用水流 失，同時協助客戶追蹤和管理其用水流失。 Water Loss Management The hilly terrain as well as various disturbances to the underground water mains in Hong Kong have caused higher risk of leakage. At the WSD, we have implemented the following measures to manage our water mains and optimise operational performance of the water supply network, reducing pipe bursts and water loss while helping consumers track and manage their water loss. 「智管網」 在「智管網」計劃下，我們在全港食水分配管網內逐步設立 約2 400 個監測區域，利用監測和感應設備檢視用水流失的情 況。其中部份監測區域亦用作水壓管理區域，配有減壓裝置， 將水壓調節到合適水平，以減少滲漏引致的用水流失。截至二 零二三年年底，我們已設立約 1 960 個監測區域，目標在二零 二五年內完成整個「智管網」的建造工程。 我們亦已建立「智能管網管理電腦系統」來收集各監測區域大 量的管網數據，從中識別異常情況，從而決定最合適和最有效 的網管管理措施。這些措施包括： Water Intelligent Network Under the project "Water Intelligent Network" (WIN), we have progressively established about 2 400 District Metering Areas (DMAs) installed with monitoring and sensing equipment in our fresh water distribution network across the territory to monitor water loss. Some of these DMAs are also designated as Pressure Management Areas (PMAs) and equipped with pressure reduction devices that can modulate water pressure to a suitable level to reduce the quantity of water loss due to leakage. As at December 2023, we have set up about 1 960 DMAs and we aim to complete the WIN network development by 2025. An "Water Intelligent Network Management System" has also been established to collect vast amount of data from these DMAs and identify anomalies for follow-up actions with the objective to determining the most suitable and effective network management measures. These measures include: 主動探測滲漏 Active Leakage Detection 水壓管理 Pressure Management 快速維修滲漏水管 Speedy Repair of Water Main Leaks 更換及修復水管 Replacement and Rehabilitation of Water Mains 我們的目標是在二零三零年前，利用先進技術及風險為本的資產管理 策略，將政府水管的滲漏率從現時二零二三年約14% 降低至10% 以下。 By 2030, we aim to reduce the leakage rate of public water mains from the current 14% in 2023 to below 10% by adopting advanced technologies and strategic risk-based asset management. 2023 14% 2030 < 10% 58 水務署 二零二三至二四年年報 WSD Annual Report 2023/24 Enhance 提升 Menu 目錄
