中水重用及雨水回收 從住宅和工業收集的中水和回收的雨水，經處理後可重新用於 非飲用用途，從而減少食水用量。我們於二零二零年九月開始， 在安達臣道石礦場用地發展項目中，興建一套每年可處理最高 達 120 萬 立方米的中央中水重用系統。系統將由二零二四年開 始分階段投入服務，以配合區內人口發展。 中央中水重用系統包括中水處理廠、抽水系統、貯存經處理中 水的配水庫，及用於收集中水和向該發展區輸送經處理的中水 作沖廁及其他非飲用用途的管道。 政府牽頭推動中水重用及雨水回收系統，更頒布內部指引，在 新的政府工程項目採用這些循環再用水設施。在此倡議下，截 至二零二三年三月，約有 130 個政府工程項目中的新建大樓已 配備中水重用及/ 或雨水回收系統。水務署天水圍大樓是支持 相關倡議的政府工程項目之一。 為推動私營企業採用中水重用和雨水回收，我們在香港綠色建 築議會的綠建環評新建建築 2.0 版提出新規定，藉以鼓勵發展 商在新發展項目中採用中水重用和雨水回收系統。截至目前， 約 190 個獲得綠建環評新建建築 1.2 或 2.0 版認證的項目已採 用循環再用水設施。 Grey Water Recycling and Rainwater Harvesting Grey water collected from households and industries as well as rainwater harvested can be treated and reused for non-potable uses thereby reducing fresh water consumption. From September 2020, we began the construction of a centralised grey water recycling system with a maximum treatment capacity of 1.2 million m3 per year at the Anderson Road Quarry Site Development. The centralised grey water recycling system will be commissioned in phases starting from 2024 to tie in with the population intake of the development. The centralised grey water recycling system consists of a grey water treatment plant, a pumping system, a service reservoir for storing treated grey water, and water mains for grey water collection and distribution of the treated grey water within the development for flushing and other non-potable uses. The Government is leading by example in adopting grey water recycling and rainwater harvesting systems with the promulgation of internal guidelines for installing these water recycling facilities in new government projects. Following this initiative, new buildings of approximately 130 government projects have been equipped with grey water recycling and/or rainwater harvesting systems as at March 2023. The WSD Tin Shui Wai Building is one of these government projects supporting the relevant initiative. To advance adoption of grey water recycling and rainwater harvesting in the private sector, we have proposed new provisions in the Hong Kong Green Building Council’s Building Environmental Assessment Method (BEAM) Plus New Buildings Assessment Tool Version 2.0 to incentivise project owners to adopt grey water recycling and rainwater harvesting systems in their new development projects. To date, about 190 certified projects under the BEAM Plus New Buildings Assessment Tool v1.2 and v2.0 have initiated efforts in adopting water recycling facilities. 我們於二零二零年九月開始，在安達臣道石礦場用地發展項目中， 興建一套每年可處理最高達 From September 2020, we began the construction of a grey water recycling system with a maximum treatment capacity of 立方米的中水重用系統。 m3 per year at the Anderson Road Quarry Site Development. 1 .2 million 百萬 水務署 二零二二至二三年年報 WSD Annual Report 2022/23 37 Scale up 升 級 開 拓
