Scenario 16A Transmission Main Rehabilitation
Project Owner: City of Phoenix
Priority 1 (Phase 1) of this project includes the rehabilitation of approximately 5,000 LF of existing 60” PCCP water transmission main using a 56” welded steel liner. The pipe is located along Superior Avenue from 40th Street to 44th Street and 44th Street from Superior Avenue to University Drive. Work includes excavation of five access pits and development of MOPOs to dewater the existing 60” transmission main from Booster Pump Station 1-B3 to Roeser Road and 36th Street. In addition to the installation of steel lining and associated grouting and morter lining, Achen-Gardner is managing access and associated confined space requirements as well as replacing the pavement and landscaping at the five access pit locations, relocating existing waterlines, demo/removing pipe, and filling and disinfecting the transmission main upon completion of the rehabilitation.
