Report
Summary
Well 301 is currently in design, with drilling and construction scheduled for summer 2017. Expected production capacity is about 1,200 to 1,500 gallons per minute (gpm). Water pumped from the well will be used to supplement supply for potable 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 (5-6 months of recharge). The goal of recharge is to stabilize water levels in the northeast valley Phoenix aquifer.
NCS Engineers will perform design services to include the well pump and all associated piping necessary to connect it to our existing water distribution system, design of the electrical components necessary for the well to operate, and to tie into the Water Services Department's Supervisory Control and Data Acquisition (SCADA) system so that it is fully automated.
