「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，以監察用水流失的情況，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。截至二零二二年底，我們已 設立約 1 750 個監測區域，並訂立於二零二五年設立2 400 個 監測區域的目標。每個監測區域均裝有監測設備和感應器，持 續監測用水流失。 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 的管網管理措施。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) 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 end 2022, we have set up about 1 750 DMAs and we aim to establish 2 400 DMAs by 2025. Monitoring and sensing equipment installed in each DMA allows continuous monitoring of water loss therein. 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: 目標在二零三零年前，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二零二二年底的約14.4%降低至10%以下。 By 2030, we aim to reduce the leakage rate of public water mains from the current 14.4% at end 2022 to below 10% by adopting advanced technologies and strategic risk-based asset management. 更換及修復水管 Replacement and Rehabilitation of Water Mains 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 2022 2030 < 10% 14.4% 水務署 二零二二至二三年年報 WSD Annual Report 2022/23 29 Scale up 升 級 開 拓
