「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。截至二零二一年底，我們已 設立約1 550 個監測區域。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。 我們已建立「智能管網管理電腦系統」來協助收集各監測區域 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 been progressively establishing 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 2021, we have set up about 1 550 DMAs. Monitoring and sensing equipment installed in each DMA allows continuous monitoring of water loss therein. An “Water Intelligent Network Management System” has been established to assist in collecting vast amount of data from these DMAs, identifying 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，將政府水管的滲漏率從現時約15%降低至10% 以下。 By 2030, we aim to reduce the leakage rate of public water mains from the current about 15% to below 10%. 15% 2022 2030 < 10% 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 現新 Innovate 水務署 二零二一至二二年年報 WSD Annual Report 2021/22 30
