Water Pollution Control Measures and Test Reporting Management Regulations Article 47
To maintain normal supply of water, the water supply plant may take emergency response measures and discharge wastewater directly when the Central Weather Administration issues a warning of torrential rain or when a natural disaster occurs and the concentration of the suspended solids in the raw water exceeds 2,000 mg/l or the turbidity exceeds 2,000 NTU and, as a result, the wastewater treatment facilities cannot operate normally.The water supply plan shall incorporate the emergency response measures referred to in the preceding paragraph in the approval documents or permits (documents) for Pollution Control Measures, and take actions according to the following requirements:I. The settling basin and sludge thickener shall be cleared first.II. A notice shall be sent to the downstream water users and the local competent authority shall be informed.III. Daily inspection shall be conducted for the turbidity and suspended solid concentration of the raw water and the suspended solid concentration of the effluent, and a record shall be made for such inspection; the record shall be retained as a reference for five years.The water supply plant is responsible for removal or repair of any accumulation of sludge or damage that occurs due to emergency response measures that the water supply plant took.
中文原文 水污染防治措施及檢測申報管理辦法第47條
自來水廠為維持正常供水，於中央氣象署發布豪雨特報或天然災害發生時，其原水懸浮固體濃度超過每公升二千毫克或濁度超過二千濁度單位（NTU），致廢水處理設施無法正常操作，得採取緊急應變措施，直接排放。
自來水廠應將前項緊急應變措施，納入水措計畫核准文件或許可證（文件），並依下列規定辦理：
一、沉澱池及污泥濃縮池，應先淨空。
二、排放前應先通知下游用水者，及通報當地主管機關。
三、排放期間應按日檢測並記錄原水濁度、懸浮固體濃度及放流水懸浮固體濃度；其檢測紀錄應保存五年，以備查閱。
自來水廠因採取緊急應變措施所造成之淤積或損害，應負責清除或修復。
