快速增长的人口和城市化带来了日益增长的消费需求 该地区的地下水资源。作为其主要方法之一 补充地下水，奥兰治县在全国范围内发展了一个广泛且不断扩大的城市 回收和再利用系统，使用经过高度处理的再生水作为替代水 资源自1986年以来，该县已100%重复使用其系统产生的再生水 为了有益的目的。 该县的各种系统平均每天生产约4500万加仑的水 再生水的有益应用。这些用途包括:农业、商业和农业 住宅灌溉；通过快速渗透盆地（肋骨）补给地下水；冷却 发电用水；以及湿地改善。 该县继续以负责任的态度通过以下途径扩大再生水的使用: 实施经过验证的创新再利用应用程序，用于保护、充电和回收 改善环境的目的。本文概述了奥兰治县的 现有的回收和再利用系统及其计划的扩建项目。包括表、图。

Rapidly growing population and urbanization have created an increasing consumptive demand on the region's groundwater resources. As one of its primary methodologies to conserve and recharge groundwater, Orange County has developed an extensive and expanding countywide Reclamation and Reuse System that uses highly treated reclaimed water as an alternate water resource. Since 1986, the County has reused 100% of the reclaimed water produced by its system for beneficial purposes. On an average day, the County's varied system produces approximately 45 million gallons of reclaimed water for beneficial applications. These uses include: agricultural, commercial and residential irrigation; groundwater recharge through rapid infiltration basins (RIBs); cooling water for power generation; and, wetland enhancement. The County continues to responsibly expand the use of reclaimed water through the implementation of proven and new innovative reuse applications for conservation, recharge, and environmental enhancement purposes. This paper provides an overview of Orange County's existing Reclamation and Reuse System, and its planned expansion projects. Includes table, figure.
