本文的重点是社区水资源保护和需求，而不是经济激励或技术援助计划。它简要介绍了西方各州的用水效率、有益用途和水分配权之间的复杂关系。本文选择性地介绍了各种州计划的例子。这些信息来自可用的文章和论文、州法律和项目文件的审查，以及对选定州的州项目经理的电话采访。通常情况下，作为另一个州计划的一个条件，水资源保护规划的要求针对取水许可证申请人、申请费率变更的供水商、废水排放许可证申请人、超过一定规模的供水商，以及赠款和贷款计划的申请。 通常，州政府要求将某些部分纳入节水计划，包括计量等系统措施和需求管理措施，如公共教育或促进节水装置使用的管道规范。概述了审查和执行等行政程序。本文讨论的策略包括在水价监管中的保护、节水型管道装置、州一级的节水型管道装置要求、强制性保护措施以及州机构之间的综合项目。

This paper focuses on community water conservation, and on requirements, not economic incentives or technical assistance programs. It briefly touches on the complex relationships between water efficiency, beneficial uses, and water allocation rights in western states. This paper selectively presents examples of a variety of state programs. This information was gathered from available articles and papers, review of state laws and program documents, and telephone interviews with state program managers in selected states. Commonly, a requirement for water conservation planning as a condition of another state program targets applicants for water withdrawal permits, water suppliers petitioning for a rate change, wastewater discharge permit applicants, water suppliers over a certain size, and applications for grant and loan programs. Often, the state requires certain components to be incorporated in a water conservation plan, including system measures such as metering, and demand management measures, such as public education or a plumbing code that promotes the use of water saving devices. Administrative procedures, such as review and enforcement, are overviewed. Strategies discussed in this paper include conservation in water rate regulation, water-efficient plumbing fixtures, state level water-efficient plumbing fixture requirements, mandatory conservation measures, and integrated programs among state agencies.
