水资源再利用需要纳入水资源规划过程。这是一个直接解决管理和扩大我们有限的饮用水资源以及安全和适当处理废水的挑战的概念。地下滴灌概念为传统污水处理方法提供了一种非常可行且有吸引力的替代技术，同时解决了节水问题以及景观和农业的灌溉需求。本文讨论了夏威夷州两个使用再生水的永久地下滴灌项目的设计、实施和管理，该项目符合夏威夷州现行的再利用指南。

Water reuse needs to be included in the water planning process. It is a concept that directly addresses the challenges of managing and extending our limited potable water resources and the safe and proper disposal of wastewater effluent. The subsurface drip irrigation concept presents a very viable and attractive alternative technology to conventional effluent disposal methods while simultaneously addressing the issues of water conservation and the irrigation needs of landscape and agriculture. This paper discusses the design, implementation, and management of two permanent subsurface drip irrigation projects in Hawaii using reclaimed water in accordance with the State of Hawaii's current reuse guidelines.
