Sewer
Rehabilitation Phase I & II
Phoenix, Arizona
Dibble Engineering developed the design for the rehabilitation
of City of Phoenix sanitary sewers located in 23rd Avenue,
24th Avenue, 7th Avenue, and Osborn Road with a total
length of 4.5 miles. A detailed condition assessment
was performed of sanitary sewer pipe ranging from 54-inch
to 24-inch diameter and 57 manholes/structures utilizing
closed-circuit television and field inspections. Information
collected from the assessments was incorporated into
the design and technical specifications consistent with
National Association of Sanitary Sewer Companies (NASSCO)
standards for Cured-In-Place-Pipe (CIPP) rehabilitation.
This project was completed using the CM@ Risk contract
delivery method.
