Regulations on Governing the Developer’s Use of Reclaimed Water Article 3
For any development initiated by the developer, if water intake quantity in the water consumption plan reaches 20,000 cubic meters per day or more, 50% or more of the industrial water consumption in the water consumption plan should be systemic reclaimed water.In the event that the municipal, county (city), or the designated area in which the initiated development provided in the preceding paragraph is located lacks sufficient conditions for systemic reclaimed water supply, the developer may implement one of the following as alternatives:1. Reuse of wastewater (sewage) not drained into the sewer system past the effluent or discharge point after it has been under the necessary treatment or processing.2. Exchange of water sources with an existing water intake enterprise in the same water supply area, as a substitute for fulfilling its obligation of using systemic reclaimed water.If the developer, after evaluating the preceding alternatives, determines that the necessary quantity of systemic reclaimed water cannot be adequately supplemented, it may resort to other alternatives to fill the gap after acquiring the approval of the reasonableness of its water consumption by the central competent authority. However, in the event of an increase in systemic reclaimed water usage for development after the approval of the water consumption plan, the central competent authority may order the developer to propose a modified water consumption plan for using additional systemic reclaimed water.
中文原文 水源供應短缺之虞地區使用再生水辦法第3條
開發單位興辦開發行為用水計畫之計畫用水量達每日二萬立方公尺以上者，用水計畫中工業用水應使用至少百分之五十系統再生水。
前項開發行為所在直轄市、縣（市）或特定園區內之系統再生水供應條件不足時，開發單位得採下列方式之一替代之：
一、取用廢（污）水放流或排放點後，未排入下水道系統之廢（污）水或放流水，經處理再利用。
二、與同一自來水供應地區內之既有用水事業交換水源，以代替履行其使用系統再生水之義務。
開發單位經評估前項替代方式仍無法補足第一項應使用系統再生水量時，經中央主管機關審查其用水計畫之合理性後，得就其不足部分以其他方式替代之。
但用水計畫核定後，有新增開發之系統再生水，中央主管機關得令開發單位提出修正用水計畫，增加使用系統再生水。
