Total Water Management 全 面 水 資 源 管 理 As part of advancing Hong Kong into a smart city, we have introduced a smart water meter system — Automatic Meter Reading (AMR) since 2018 in new public and private developments to further promote water efficiency and smart living in the community. Besides improving accuracy and efficiency in water meter readings, we seek to raise customer awareness of water conservation and inspiring their behaviour changes through the provision of water consumption information via the AMR mobile app. The AMR system also helps in enabling leakage detection and repair of water mains through timely alerts on unusual consumption due to water seepage or dripping taps. With a view to extending the use of AMR to existing premises, we are assessing the feasibility of adopting wireless technology. Due to its remoteness from high-rise buildings and suitability for radio gateway telecommunications, Tai O is selected as the first trial of our wireless AMR solution to improving efficiency and customer service. During the year, the trial was initially completed with satisfactory results and a total of 500 smart water meters were installed in 2021. We will further investigate the viability of the wireless technology. 作為推動香港成為智慧城市的一部分， 我們從二零一八年起，於新建公營及私人 發展項目引入智能水錶系統——自動讀錶 系統，以進一步促進社區的用水效益和智 能生活。除了改善讀錶的準確度和效率， 我們期望透過自動讀錶系統的流動應用 程式，提供客戶用水量的資訊，從而提高 客戶節約用水的意識並鼓勵他們作出行為 上的轉變。此外，當水管滲漏或滴漏的 水龍頭導致異常的用水量時，系統會適時 發出警報，使客戶能作出滲漏檢測和水管 維修。 為擴展自動讀錶系統的應用至現有處所， 我們正研究採用無線技術的可行性。由於 大澳不僅遠離高層建築物，而且適合無線 電網關通訊，我們選擇了它為首個無線自動 讀錶系統的試點，以提升用水效益和客戶 服務。試驗已於年內初步完成，結果令人 滿意。我們於二零二一年安裝了共 5 0 0 個 智能水錶。我們將進一步研究無線技術的 可行性。 Leveraging advanced technologies, we have been actively expanding the use of lower grade water, which includes salt water and recycled water (i.e. reclaimed water and treated grey water and harvested rainwater) for non-potable uses, for example, toilet flushing, landscape irrigation and street cleansing to help conserve fresh water resources. 我們利用先進技術，致力擴大使用次階 水，包括海水及循環再用水(即再造水、 重用中水及回收雨水)，用於沖廁、園景 灌溉和清潔街道等非飲用用途，務求節省 食水資源。 自動讀錶系統 Automatic Meter Reading System 次階水 Lower Grade Water 為改善讀錶的效率和準確度，我們目前正於漁村棚屋、村屋、公共屋邨和政府設施測試無線自動讀錶系統。 Wireless AMR system is currently being tested in fishermen ’ s huts, village houses, public housing estates and government facilities with a view to improving efficiency and accuracy in water meter readings.
