随着南加州对水的需求持续增长，对替代供水的需求变得越来越必要。本文介绍了奥兰治县、河滨县和圣贝纳迪诺县六个新的循环水设施的案例研究，旨在产生约60 mgd的总平均日流量。这些设施将有助于解决该地区未来的用水需求。这六个设施包括:红土城污水处理和处置设施；圣贝纳迪诺市水利局快速渗透和提取设施；东部城市水区莫雷诺谷区域水资源回收设施；东部城市水区Temecula Valley区域水资源回收设施；圣玛格丽塔水区奇基塔水回收设施；以及内陆帝国公用事业局5号区域工厂。

As the demand for water continues to grow in southern California, the need for alternative supplies becomes increasingly necessary. This paper presents case studies for six new recycled water facilities in Orange, Riverside and San Bernardino Counties designed to produce a total average daily flow of approximately 60 mgd. These facilities will help to address future water needs in the region. The six facilities include: City of Redlands Wastewater Treatment and Disposal Facilities; City of San Bernardino Municipal Water Department Rapid Infiltration and Extraction Facility; Moreno Valley Regional Water Reclamation Facility, Eastern Municipal Water District; Temecula Valley Regional Water Reclamation Facility, Eastern Municipal Water District; Chiquita Water Reclamation Facility, Santa Margarita Water District; and, Regional Plant Number 5, Inland Empire Utilities Agency.
