Design Build Services, NEWRF & NWWRF PCCP Replacement (Project No. 23109-100)

The NEWRF PCCP Replacement is Phase 4 of a series of projects to replace the PCCP transmission main supplied from the Northeast Water Reclamation Facility (NEWRF). The project involves the replacement of approximately 7,000 linear feet of 36" Pre-stressed Concrete Cylinder Pipe (PCCP) installed in 1977 along 77th/78th Avenue North, from 16th Street North to 1st Street North, using Interpace Corporation pipe manufactured with Class IV prestressing wire, which is known to be related to premature pipe failures. The NWWRF PCCP Replacement involves the replacement of ~15,286 linear feet of 30” PCCP reclaimed water main (RWM) supplied by the Northwest Water Reclamation Facility (NWWRF). Like the NEWRF reclaimed water main, the NWWRF main was constructed using Interpace Corporation pipe manufactured with Class IV prestressing wire, which is known to be related to premature pipe failures. The section of the main to be replaced starts at the NWWRF and then runs south through the Azalea Recreation Center and along 72nd Street N., west on 8th Ave. N., South on unimproved right-of-way for 73rd Street N. and then along 73rd Street N., east on 2nd Avenue S. through Circle Park, and east along Poinsettia and 5th Avenues S. to 64th Street S. where it connects to the existing main.
