Report
Summary
ASR Well 303 is currently in design with drilling and construction scheduled for summer 2017. The expected production capacity is approximately 1,200 to 1,500 gallons per minute (gpm). Water pumped from the well will be used to supplement supplies for potable water customers in northeast Phoenix. During periods of low water demand, the City plans to store surplus potable water in the aquifer by injecting potable water down this well. The anticipated injection rate is 1,200 gpm with an objective of recharging 1,000 to 1,200 acre-feet per year (five to six months of recharge). The goal of recharge is to stabilize water levels in the northeast valley Phoenix aquifer.
Brown and Caldwell, Inc. will perform design services to include the well pump and all associated piping necessary to connect it to our existing water distribution system, a de-chlorination system, the electrical components necessary for the well to operate, and to tie into the City’s Supervisory Control and Data Acquisition (SCADA) system so that it is fully automated.
