本文讨论了水资源保护与饮用水国家循环基金（DWSRF）之间的关系，以及由于这种关系，如何将水资源保护视为在基础设施融资、能力开发、可承受性和这项里程碑式法律的其他关键规定方面具有潜在作用。讨论了保护指南、保护规划的资金来源，以及保护条款如何使DWSRF受益，包括它们如何:帮助扩大有限的公共资金；可能影响设施规划；可以作为能力发展的衡量标准；避免不必要的成本；与水源保护齐头并进；并为综合规划做出贡献。包括6个参考文献、表格。

This article discusses the relationship between water conservation and the Drinking Water State Revolving Fund (DWSRF) and how, as a result of this relationship, conservation can be regarded as having a potential role in the context of infrastructure funding, capacity development, affordability, and other key provisions of this landmark law. Discussed are conservation guidelines, how conservation planning may be funded, and how conservation provisions benefit the DWSRF, including how they: help stretch limited public funds; can affect facility planning; can be a measure of capacity development; avoid unnecessary costs; go hand in hand with source water protection; and, contribute to integrated planning. Includes 6 references, tables.
