食水水質監測計劃 為有效監測食水水質及建立全港食水水質數據庫用作檢討香港食 水標準，我們實施了一套食水水質監測計劃，於濾水廠、海水化 淡設施、配水庫、食水缸、供水接駁點和公眾可達的用戶水龍頭 等地方收集食水樣本。我們亦透過推行「水質監測優化計劃」擴 大食水水質監測的範圍，在全港隨機抽出處所，並在其用戶水龍 頭收集食水樣本，加強食水的水質監測。上述用戶水龍頭收集的 食水樣本將會就六種金屬( 即銻、鎘、鉻、銅、鉛和鎳)、餘氯 和埃希氏大腸桿菌等作化驗。我們每週均會將相關水質統計數據 於水務署網站內公布。 Drinking Water Quality Monitoring Programme To monitor the quality of drinking water and facilitate the creation of a territory-wide database for reviewing the HKDWS, we have implemented a drinking water quality monitoring programme to collect drinking water samples from water treatment works, desalination plant, service reservoirs, fresh water tanks, connection points and publicly accessible consumers’ taps. We extended the drinking water quality monitoring by implementing "Enhanced Water Quality Monitoring Programme" to strengthen our water quality monitoring at consumers’ taps in randomly selected premises in Hong Kong. At present we collect drinking water samples from these drinking taps for testing 6 metals, namely antimony, cadmium, chromium, copper, lead and nickel that could be present in internal plumbing system, as well as residual chlorine and E.coli. The water quality statistics are published every week on the WSD's website. 水塘的無人船系統 為提升水塘水質監測，水務署人員自二零一一年發起使用無人 船系統於在水塘進行自動監測水質和取樣，目前系統已經發展 到第四代。監測能使下游濾水廠更有效控制食水處理過程， 確保食水安全。 每艘無人船均配置了水質監測裝置，用於監測溫度、導電率、 混濁度、溶解氧、酸鹼值、葉綠素 -a 和藍綠藻；以及自動導航 和避障系統，確保在運行時能繞過障礙物。 在二零二四年第一季，我們進一步提升智慧航線規劃及智能水 質監測和取樣功能，讓無人船能規劃航行路線，並可根據實時 的水質情況即時作出應變。例如當無人船的檢測發現水質明顯 變化時，系統會自動增加檢測點及採樣的數量，以便收集更多 數據，從而提升營運效率。 Unmanned Surface Vessels System at Impounding Reservoirs To advance water quality monitoring, since 2011, our staff have initiated smart use of unmanned surface vessel ("USV") system, currently in its 4th generation of development, to perform automatic water quality monitoring and sampling in impounding reservoirs. This system facilitates the effective control of water treatment process at downstream water treatment works to ensure the safety of drinking water supply. Each USV system is equipped with a water quality monitoring unit to monitor temperature, conductivity, turbidity, dissolved oxygen, pH, chlorophyll-a and blue green algae; as well as auto-navigation and obstacle avoidance systems for navigating around obstacles during operation. In the first quarter of 2024, we made further enhancements in smart route planning and intelligent water quality monitoring and sampling. These enhancements enable the USV system to plan the navigation route as well as respond in real time to changes in water quality. For example, when the USVs detect significant changes in water quality, the system will automatically increase the number of monitoring points to collect more data and conduct additional sampling, thereby improving operational efficiency. 67 水務署 二零二三至二四年年報 WSD Annual Report 2023/24 Enhance 提升 Menu 目錄
