Report
Summary
The below-ground portion of ASR Well 303 is currently in design with drilling and construction scheduled for summer 2017. The expected production capacity is about 1,200 to 1,500 gallons per minute (gpm). Water pumped from the well will be used to supplement supplies 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, which aims to stabilize water levels in the northeast valley Phoenix aquifer.
MGC Contractors, Inc., will be responsible for means and methods related to construction of the project, participating with the City in the goal setting process for local and Small Business Enterprise (SBE) participation, implementing the SBE process and preparation of the GMP proposal. MGC Contractors, Inc., will be required to solicit bids from prequalified subcontractors to perform work under the City's subcontractor selection process. MGC Contractors, Inc., may also compete to self-perform limited amounts of work for this project. MGC Contractors, Inc., will assume the risk of delivering the project through a Guaranteed Maximum Price.
