自《美国能源政策法》两年前生效以来，新一代节水型管道装置已安装在家庭、企业和机构中。这一过程将持续到2025年左右，届时所有现有的高容量固定装置都将被更换。该法案的通过引发了一些有趣的问题，这些问题对水利设施——尤其是那些有保护项目的水利设施——具有技术、财务和政策影响。本文对其中一些影响进行了综述。包括5个参考文献、表格。

Since the US Energy Policy Act went into effect two years ago, a new generation of water-efficient plumbing fixtures has been installed in homes, businesses and institutions. This process will continue through about 2025, by which time all existing high-volume fixtures will have been replaced. Passage of this act has raised interesting issues that have technical, financial, and policy implications for water utilities--particularly those with conservation programs. This article reviews some of these effects. Includes 5 references, tables.
