加利福尼亚州是美国第一个实施水再利用条例的州 并于1918年通过了第一个标准。该州的规章制度已被废除 自那时以来，已经进行了多次修订，目前正在再次进行修订。在里面 近年来，其他州也采用了水回收和再利用的标准 已被确定为全面水资源管理的关键组成部分。虽然 美国联邦政府表示，目前还没有直接针对水资源再利用的联邦法规。 环境保护局（EPA）已经认识到水的再利用和回收的价值 1992年出版的指南。影响监管发展的趋势如下: 本文提出。许多州已经或正在开发水的再利用 规则或指导方针。许多州都有独立机构的结构 负责废水和饮用水的管理。 当走向 在制定水资源再利用法规时，各州面临着 在现有结构中确定适当的实体，以建立和 执行水资源再利用条例。对各种结构进行了比较。 现有或提议的州标准在重用类型上都有很大差异 允许在各自的处理和再生水中使用 质量要求。几个州的现行法规 制定了综合标准，如亚利桑那州、加利福尼亚州、佛罗里达州、俄勒冈州、， 德克萨斯州和华盛顿州在重用应用程序方面各不相同。EPA的水再利用 指导方针涉及许多类似的重用应用程序。比较 本文介绍了重用应用程序的各种标准，并对此进行了讨论 关于制定水再利用联邦法规的必要性或适当性。 实施挑战伴随着新法规的制定和提高 新问题。国家标准的优点和缺点将是 根据对目前有标准的国家的潜在影响提出 还有那些没有标准的。专业组织，如美国 水利工程协会（AWWA）和水环境联合会（WEF）已经 以多种方式支持重用。这些努力及其影响也很重要 本文对此进行了讨论。包括9个参考文献和表格。

California was the first state to implement water reuse regulations in the United States and adopted its first criteria in 1918. That state's regulations have been revised several times since then, and are currently under revision once again. In recent years, other states have adopted criteria as water reclamation and reuse have been identified as key components of total water resources management. While there are no federal regulations directly addressing water reuse, the U.S. Environmental Protection Agency (EPA) has recognized the value of water reuse and published guidelines in 1992. Trends affecting regulatory development are presented in this paper. A number of states have or are developing water reuse regulations or guidelines. Many states have a structure with separate agencies responsible for regulating wastewater and potable water. When moving towards establishing water reuse regulation, states have been confronted with the need to identify the appropriate entity within the existing structure to establish and enforce water reuse regulations. Comparisons of various structures are presented. The existing or proposed state criteria vary considerably both in types of reuse applications allowed and in their respective treatment and reclaimed water quality requirements. Existing regulations from several states that have developed comprehensive criteria, such as Arizona, California, Florida, Oregon, Texas, and Washington, vary for reuse applications. The EPA water reuse guidelines address a number of similar reuse applications. A comparison of various standards for reuse applications is presented which leads to a discussion of the need or appropriateness of developing federal regulations for water reuse. Implementation challenges accompany the development of new regulations and raise new questions. The advantages and disadvantages of national standards will be presented in light of the potential impact on states that currently have criteria and those that have no criteria. Professional organizations such as the American Water Works Association (AWWA) and the Water Environment Federation (WEF) have supported reuse in a variety of ways. These efforts and their impacts are also discussed in this paper. Includes 9 references, tables.
