Insituform Wins Two Sewer Rehabilitation Contracts from Hallsdale-Powell Utility District for Combined Value of $6.5 Million

SAINT LOUIS, MO, March 9, 2010–Insituform Technologies, Inc. (Nasdaq Global Select Market: INSU) announced today it has been awarded two contracts with a combined value of $6.5 million from the Hallsdale-Powell Utility District in Knoxville, Tennessee. These contracts mark the first time Insituform will work with the District. Hallsdale-Powell will fund the projects with a state revolving fund loan secured through the American Recovery and Reinvestment Act (ARRA), Hallsdale-Powell had planned to complete this project in a series of contracts to be awarded over the next three years. However, by accessing the additional funds available through the ARRA, the District will be able to upgrade its system more quickly, significantly reducing infiltration into its existing system. Insituform will rehabilitate approximately 25 miles of sewer pipelines with its core cured-in-place pipe (CIPP) technology. The project is expected to be completed by June 2011.

Bobby O’Dell, Insituform’s General Manager-Central Region, said, “Insituform has been the leader in CIPP technology for nearly 40 years. We look forward to utilizing our proven processes and project management experience to assist the Hallsdale-Powell Utility District in upgrading its sewer system.”

Insituform will partner with Hallsdale-Powell Utility District as well as the engineering firm, Jordon Jones and Goulding, to inform the residents of the Knoxville area about the project and the benefits of the rehabilitation efforts.

“It’s clear Hallsdale-Powell Utility District truly understands the importance of quality infrastructure rehabilitation and how it can dramatically help improve the daily life of communities, neighborhoods and residents,” said David Reece, regional manager at Jordan, Jones and Goulding. “JJG is pleased to work with the talented professionals at Insituform on this project and we are eager to assist all of the people living and working along the 25 miles of wastewater pipelines that are to be rehabilitated.”

Insituform’s crew based in Knoxville will begin work on this project in March 2010. A minority-owned business will provide the open-cut work and pipe bursting for a portion of the project. Additional contractors from Tennessee will provide the required manhole rehabilitation, lateral rehabilitation, pipe bursting and closed-circuit television inspection services as subcontractors to Insituform.
