St. Louis Sewer District Awards CIPP Contracts

The Metropolitan St. Louis Sewer District (MSD) has awarded two contracts valued at approximately $10.4 million to Insituform Technologies USA LLC, a subsidiary of Aegion Corp. The contracts are a part of MSD’s $4.7 billion sewer system improvement program.

This project includes the installation of approximately 47 miles of cured-in-place pipe (CIPP) in small-and medium-diameter sewer pipelines located in mostly residential areas. There is little to no disruption to surrounding areas during the installation of CIPP.

Insituform will install CIPP using standard inversion methods as well as Insituform’s proprietary pull-in installation method, iPlus Infusion.  iPlus Infusion will be used on most small diameter pipelines on this project and allows increased productivity during the installation process.

Insituform will begin work on this project in August 2013 and is anticipated to complete the work within one year.
