Reclaimed Water System uses Vadose Zone Recharge Wells Approximately 20 miles northwest of downtown Phoenix in Maricopa County is the second fastest-growing municipality in the greater Phoenix metropolitan area – the city of Surprise. Apr 1st, 2008 Vadose zone wells typically have up to 60 metres in-depth, and their diameter ranges between 1 and 2 metres (Bouwer, 2002; Liang et al., 2018). They are also known as dry wells or recharge shafts. Vadose zone recharge wells and associated facilities, including reclaimed delivery pipelines and filters, were designed and constructed at two separate locations served by reclaimed water supplies from the South Water Reclamation Plant (WRP). The Butler WRF is located in the West Salt River sub-basin of the Phoenix Active Management Area.
