Surprise converts raw sewage into its final form of Class A+ quality reclaimed water through biological treatment, filtering and disinfection. The wastewater is regularly monitored to ensure that it meets state and federal regulations for direct reuse and recharge. After undergoing treatment, the reclaimed water flows through pumping stations where it is sent to various end users to be reused. The majority of Surprise's reclaimed water is used for agricultural irrigation, groundwater recharge, landscape irrigation and dust control. On average, approximately 7.3 million gallons per day are reused or recharged.
