減緩氣候變化 ISO 環境管理系統 我們致力在水務工程的各個階段包括規劃、設計及建造的過程 盡量降低對環境造成的影響。我們每年在《 ISO 14001:2015 環 境管理系統》的框架下訂立新方向和目標，讓我們在環境管理 系統及環境保護方面持續進步。 ENVIRONMENTAL MITIGATION ISO Environmental Management System We strive to minimise the environmental impacts arising from our waterworks construction throughout the planning, design and construction processes. Each year, new objectives and targets are established under the ISO 14001:2015 Environmental Management System (EMS) to continually improve our EMS and environmental performance. 現場生產氯氣 在十二間主要濾水廠的消毒設備升級工程完成後，我們隨即 全面使用現場氯氣生產的設備取代液態氯，令食水供應的質 素、安全及可靠性均得到顯著改善。水務署已大規模使用現 場生產氯氣技術用作食水消毒以供香港巿民使用，其規模更 是全球之冠。 透過採用先進的臭氧水處理技術，濾水廠的氯消耗量減少 30%。隨著二零二三年九月我們將所有剩餘液態氯的庫存耗 盡，我們無須再為氯氣在運輸和貯存過程中發生洩漏的風險而 擔憂。 Onsite Chlorine Gas Generation Following the completion of upgrading disinfection facilities from liquid chlorine to onsite chlorine generation at our 12 major Water Treatment Works (WTWs), the on-site chlorine gas generation facilities are put into operation enhancing the quality, safety and reliable supply of drinking water. The WSD has extensively applied the technology of generating chlorine gas on-site for disinfecting drinking water to the Hong Kong population, the scale of which is the first of its kind in the world. Through adopting the advanced ozone water treatment technology, the chorine consumption in WTWs could be reduced by 30%. With the depletion of the remaining liquid chlorine stock from September 2023, we have also eliminated the potential risk of chlorine leakage during transportation and storage. 87 水務署 二零二三至二四年年報 WSD Annual Report 2023/24 Enhance 提升 Menu 目錄
