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

We are committed to enhancing the management of our huge water main assets. Water main burst cases remain at a relatively low level. In 2020, about 40 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). 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 二零二零年亦只有約 40 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。 Enhancing Water Supply Reliability In-Situ Reprovisioning of Sha Tin Water Treatment Works (South Works) 提升供水可靠性 沙田濾水廠原地重置工程(南廠) 提升水管資產管理 Enhancing Water Main Asset Management 此項目旨在確保提供足夠的優質食水予由 The project aims to ensure an adequate supply of quality potable 將相繼落成的公私營住宅發展所帶來的 water to meet the anticipated increase in fresh water demand due to 額外食水需求。 the progressive implementation of new public and private housing developments.
