水務署2020/21年年報 WSD Annual Report 2020/21

Total Water Management 全 面 水 資 源 管 理 Apart from managing water loss from government mains, a series of measures, for example, installing master meters at private developments, have been put in place to monitor water loss. We also provide advice and support to property owners, management agents and service providers to facilitate leak investigations through publishing sample contract clauses and specifications, and providing a reference list of local leak detection service providers. The progressive implementation of WIN also allows us to identify hidden leaks in private water mains. Once the intelligent network detects an unusual amount of water consumption in certain DMAs, our water loss management teams will assist in on-site visual and sounding inspections, leak noise correlation surveys and leak detection step tests. In case the water loss is suspected occurring in the private water mains, advice and support would be provided to the concerned property owners and management agents. 除了管理政府水管的用水流失外，我們亦 採用一系列措施，例如為私人發展項目安裝 總水錶，以監察私人水管用水流失的情況。 我們亦透過編制合約條款及規格範本，以及 提供測漏服務供應商參考名單，為業主、 物業管理人和服務供應商提供建議和支援， 使他們能更方便安排測漏調查。 「智管網」的逐步推行讓我們能發現隱藏於 私人水管的滲漏點。當「智管網」在某監測 區域發現用水量異常，我們的負責團隊便會 到場進行滲漏調查，包括目視和聽音檢查、 滲漏噪聲相關測試和滲漏分段測試。若私人 水管出現懷疑用水流失，我們會向相關業主 和物業管理人提供建議和支援。 管理私人水管滲漏 Managing leakage of private water mains 於二零二零至二一年度，隨著「智管網」逐步實施， In 2020/21, with the progressive implementation of the Water Intelligent Network, 「智管網」 Water Intelligent Network x 5 580 個滲漏點被發現並修復 leaks were identified and repaired 每天節省超過 daily saving over 的食水 of fresh water =14 200 m 3 立方米 WSD Annual Report 2020/21 31 目標在二零三零年前，將政府水管的滲漏率從 二零一七年的15%降低至10%以下。 By 2030, we aim to reduce leakage rate of government mains from 15% in 2017 to below 10%. 15% 2017 2030 10%
