WSD Annual Report 2022/23

水安全計劃 我們採取風險為本和多重屏障的原則,確保食水安全。我們希 望透過與各界別持份者通力合作,有效實施水安全計劃,確保 從源頭至用戶水龍頭的食水水質,以保障公眾健康。 此外,我們根據世衞的《飲用水水質準則》,制訂和實施水安 全計劃。 Water Safety Plan We have taken a risk-based and multiple barrier approach to ensuring the safety of our drinking water supply. Through the effective implementation of Water Safety Plan (WSP), in joint collaboration with various stakeholders, we hope to ensure drinking water quality from sources to consumers’ taps for the protection of public health. In addition, we have developed and implemented our WSP based on the WHO Guidelines. 食水水質管理系統 我們於二零一七年檢討了部門的水安全計劃,並參考國際專家 的建議及西澳洲的實踐經驗,通過健康目標、水質政策、水安 全計劃的系統評估和監察、監督安排、溝通、培訓和公眾教育 等元素,制定了一套綜合的食水水質管理系統。 作為持續改善的一部分,我們參考內部和第三方審核的結果 及建議、海外和本地水質管理的經驗,定期檢討工作流程和 運作程序。在於二零二一年加強緊急臨時供水的風險評估後, 我們於二零二二年十月再度更新食水水質管理系統,其中包 括在濾水廠現場使用氯氣生產設施的風險評估。 Drinking Water Quality Management System In 2017, we reviewed and enhanced our WSP by developing an integrated Drinking Water Quality Management System (DWQMS) via health-based targets, water quality policy, system assessment and monitoring of WSP, surveillance arrangements, communications, training and public education, with reference to the recommendations of international experts as well as overseas practices in Western Australia. As part of our ongoing improvements, we conduct regular reviews of our practices and operational procedures referencing to the findings and recommendations of internal and third-party audits as well as overseas and local experiences in water quality management. Further to the recent enhancement in the risk assessment on emergency temporary drinking water supply in 2021, we updated the DWQMS in October 2022 to incorporate among others, risk assessment on the use of on-site chlorine generation system at water treatment works. 食水水質管理系統 DRINKING WATER QUALITY MANAGEMENT SYSTEM 水安全計劃的系統評估及監察 System assessment and monitoring of Water Safety Plan 水質政策 Water quality policy 監督安排 Surveillance arrangements 健康目標 Health-based targets 交流、培訓和公眾教育 Communications, training and public education 水務署 二零二二至二三年年報 WSD Annual Report 2022/23 44 Scale up 升 級 開 拓
