本文件为从水质角度设计、管理和/或监督城市地区非饮用水再利用计划或活动的用户提供了水再利用安全评估和公众接受参数和方法。该文件可用于非饮用水再利用项目的各个阶段，如设计、运行和后评估。 本文件适用于城市地区的非饮用水再利用，使用来自城市污水源的再生水。废水源还可以包括工业废水输入的有限贡献。虽然一些社区正在转向饮用水再利用以满足供水需求，但饮用水再使用安全评估的讨论超出了本文件的范围。

This document provides water reuse safety evaluation and public acceptance parameters and methods for users who design, manage, and/or oversee the non-potable water reuse schemes or activities in urban areas from the viewpoint of water quality. The document can be used in various stages of non-potable water reuse projects such as design, operation, and post assessment. The document is applicable to non-potable water reuse in urban areas with reclaimed water from municipal wastewater sources. The wastewater sources can also include a limited contribution of industrial wastewater input. While some communities are turning to potable reuse to meet water supply needs, discussion of safety evaluation of potable reuse is outside the scope of this document.
