Aegion Corporation’s subsidiary, Insituform Technologies Inc., has been awarded a $5.6 million contract from the city of Crest Hill, IL. Insituform expects to install approximately 135,000 feet of small- to medium-diameter Insituform cured-in-place pipe (CIPP) in residential neighborhoods throughout Crest Hill, beginning in January 2012.
Aaron E. Fundich, principal engineer for Robinson Engineering said, “Robinson Engineering has been working with the city of Crest Hill since 2008 to develop a solution to address ongoing structural deficiencies and inflow/infiltration issues for a pipeline system that has received minimal maintenance since its installation over 50 years ago. Insituform CIPP was selected to rehabilitate over 25 miles of aging pipelines because of the non-disruptive installation method as well as its capability to increase flow capacity, improve structural capability and reduce infiltration.”
It is expected that Insituform’s proprietary air inversion steam cure installation method will be used throughout the project. This installation method reduces energy and water usage by approximately 95 percent.
