水管資產管理 我們致力提升管理龐大水管資產的質素。水管爆裂的個案數字 一直維持在低水平，在二零二一年亦只有約30 宗。我們將繼 續推行以風險為本的水管資產管理策略，以維持政府供水網絡 的健康狀況，減低水管爆裂或滲漏的風險。 我們會根據水管爆裂或滲漏的後果、水管使用年期和物料、過 往爆裂或滲漏記錄、周邊環境等各項因素，為高風險的水管優 先進行改善工程，包括進行更換或修復水管，以減低水管爆裂 或滲漏的風險。此外，我們亦會為位於「爆喉熱點」（即重複 出現水管爆裂的段落）的水管進行改善工程。 Water Main Asset Management We are committed to enhancing the management of our vast water main assets. Water main burst cases remain at a relatively low level. In 2021, about 30 main burst cases were recorded. We will continue to implement a risk-based water main asset management strategy to maintain the healthiness of the government water supply networks and to reduce the risk of water main bursts or leaks. Taking into account various factors including the consequences of bursts or leaks, ages and materials of the water mains, past records of bursts or leaks, surrounding environment, etc., we accord priorities for improvement works to those water mains assessed with high risk, including replacement or rehabilitation to reduce the risk of water main bursts or leaks. In addition, we will carry out improvement works to water mains in “main burst hot spots” (i.e. sections with repeated water main bursts). 現新 Innovate 水務署 二零二一至二二年年報 WSD Annual Report 2021/22 55
