Fusible Polyvinyl Chloride Pipe Provides Owner with a Monolithic ...

Basis of Design Summary:
• Replace 70 year old section of 6-inch cast iron pipe and upgrade
with 8 inch PVC pipe. This pipe section provides a loop
network for the Honolulu International Airport South Ramp
• Design Requirements and dCh Challenges
• Potential for contaminated soils or groundwater due to
mobile fuel farms and adjacent live fuel lines
• Desire to remove gaskets/segmented pipe and limit the
amount of joints in the system
• Pipe system must be resistant to hydrocarbon permeation
• Construction will occur over active taxilanes and roadways
• Ability to deal with unforeseen abandoned utilities
• Post Design Considerations
• Pipe System must be resistant to Oxidative Degradation in
the presence of chlorine based disinfectants (Groundwater
Rule, recent studies)
