美国西南部日益增长的水需求导致蓄水层蓄水和恢复。在天气温暖的月份，再利用水的需求很高，而在天气寒冷的月份，废水流量增加，喷泉山卫生区（亚利桑那州喷泉山）寻求管理其水资源的方法。含水层储存和回收（ASR）被选为该地区水资源再利用管理系统的关键组成部分。该系统由三级处理、微滤、污水均衡、地上蓄水池、地下水蓄水池、三口注入/回收井、配水管道和泵送设施组成。 该系统的设计目的是每天回灌多达200万加仑的A级污水。该系统还设计用于每年回收一定量的水。该系统于2001年2月开始运行。除含水层蓄水外，该系统的设计还具有向当地用户供应回用水和地下水的灵活性。系统自动化通过需要有限操作员参与的监控和数据采集（SCADA）系统进行处理。运营数据将允许捷运局分析需求趋势，然后优化其设施，以满足预期需求。包括表格，如图所示。

Increasing water demands in the southwestern United States have given rise to aquifer storage and recovery. Faced with high reuse water demands during warm weather months and increased wastewater flow during colder months, the Fountain Hills Sanitary District (Fountain Hills, Arizona) sought a means of managing its water resources. Aquifer Storage and Recovery (ASR) was chosen as a key component in the District's water reuse management system. The system is comprised of tertiary treatment followed by microfiltration, effluent equalization, above ground storage reservoirs, groundwater storage, three injection/recovery wells, and distribution piping and pumping facilities. The system is designed to recharge up to 2 million gallons of Class A effluent per day. The system is also designed to recover a set volume of water on an annual basis. The system became operational in February 2001. In addition to aquifer storage, the system is designed with the flexibility of supplying reuse water as well as groundwater to local users. System automation is handled by means of a supervisory control and data acquisition (SCADA) system requiring limited operator involvement. Operational data will allow the District to analyze demand trends and then optimize their facilities to coincide with expected demands. Includes tables, figure.
