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

主要工作表現指標 Key Performance Indicators * 水務署自二零一七年九月起開始採用香港食水標準為指標，而在此之前，則一直採用世界衞生組織制訂的《飲用水水質準則》為指標。 The Hong Kong Drinking Water Standards have been adopted by WSD in the target since September 2017. Before that, the World Health Organization's Guidelines for Drinking-water Quality were adopted in the target. ** 此指標於二零一九至二零年度經修訂為「海水水質 ─ 97% 符合水務署所定的水質指標」，二零一八至一九年度則為「海水水質─ 96% 符合水務署所定的水質 指標」，而二零一七至一八年度所採用的指標為「海水水質（供水接駁位置）─ 96% 符合水務署所定的水質指標」。 The target for 2019/20 has been revised as “Salt water quality – 97% compliance with WSD Water Quality Objectives”. The target for 2018/19 was “Salt water quality – 96% compliance with WSD Water Quality Objectives”. The target in 2017/18 was “Salt water quality (at connection points) – 96% compliance with WSD Water Quality Objectives”. ^ 配水系統內（不包括系統盡頭）最低的剩餘水壓。 Minimum residual pressure in the distribution systems except at their extremities. 財政年度 Financial Year 指標 2018/19 2019/20 2020/21 Indicators 食水水質 100% 符合香港食水標準 * 達到指標 達到指標 達到指標 Fresh Water Quality Target achieved Target achieved Target achieved 100% compliance with the Hong Kong Drinking Water Standards* 海水水質 97% 符合水務署所定的水質指標 ** 達到指標 達到指標 達到指標 Salt Water Quality Target achieved Target achieved Target achieved 97% compliance with WSD Water Quality Objectives** 食水供水水壓( 15 至 30 米) ^ Fresh Water Supply Pressure 100% 100% 100% (15–30 metres) ^ 海水供水水壓( 15 米) ^ Salt Water Supply Pressure 100% 100% 100% (15 metres) ^ 因預先計劃進行的工程而暫停供水的時間長度 ( 98% 於八小時內) 達到指標 達到指標 達到指標 Water Supply Suspension Duration for Planned Work Target achieved Target achieved Target achieved (98% within 8 hours) 水錶準確程度 (偏差程度不超過± 3% ) 97.7% 98.2% 97.3% Water Meter Accuracy (inaccuracy not exceeding ± 3%) WSD Annual Report 2020/21 15 Our Profile 關 於 我 們
