San Diego Airport Project Successfully Completed

Insituform completed the rehabilitation of nearly 2,000 feet of 96-inch sanitary sewer pipes using its carbon composite cured-in-place pipe (CIPP) product. The rehabilitation was part of a $2.6 million contract for the San Diego County Regional Airport Authority.

According to Terry Henry, Insituform Business Development Manager, "The Airport Authority recognized that the addition of a new terminal and parking area at the airport would require the reinforcement of the existing sanitary sewer in order to handle the increased loading on the underground pipe. In addition to increasing the structural capabilities of the liner, the project specifications required minimal reduction in flow capacity. iPlus^® Composite, a fiber-reinforced, premium CIPP product that provides greater strength and stiffness with nearly half the wall thickness of conventional CIPP products, is the ideal solution for the Airport Authority.”

With the project site visible from the runway, other unique field conditions at the project site include soil contaminants and high ground water. Crews successfully installed the carbon composite CIPP, working with the Airport Authority and the general contractor, Charles King Company, to ensure that the challenges of this project were addressed and the Airport’s expectations were met.

The project went on to win the 2010 Trenchless Technology Project of the Year Award in the Rehabilitation category.
