Phoenix Water Main Undergoing Innovative Rehabilitation Methods
A cradle was installed between the PCCP sections at each portal. The liners were placed on the cradle and transported to the correct position within the host PCCP pipe. Once in place, the bands were cut from the steel liners and tack welded. After several liners had been fitted into place, the liners were welded longitudinally and circumferentially. The annular space between the finished line and host PCCP pipe is then grouted.
The overall project was started in 2005 and is targeted for final completion in 2013.
