Insituform Receives $4 Million (US) Drinking Water Contract Award from the City of Victoria, British Columbia

SAINT LOUIS, MO, July 6, 2010–Insituform Technologies, Inc. (Nasdaq Global Select Market: INSU) announced today it has received a contract award for $4 million (US) to rehabilitate over 11,000 feet of drinking water pipelines in Victoria, British Columbia using its InsituGuard® solution.

Work on this project, which includes 12-inch and 20-inch diameter pipelines, is expected to be completed by early 2011. InsituGuard® is a close-fit HDPE liner that renews existing pipelines with minimal disruption.

Chuck Voltz, Insituform’s Senior Vice President of North American Rehabilitation, said, “The response from the Canadian market for our solutions to rehabilitate drinking water pipelines has been extremely positive. We are adding crews and equipment to address the growing demand for our trenchless rehabilitation solutions for the drinking water market.”

Insituform has opened a new office in Montreal, Quebec, Canada to meet increased demand for both sewer and water pipeline rehabilitation in the Eastern Canadian province. Backlog for the newly opened Quebec office exceeds $3 million (US) and includes nearly $2 million (US) for projects involving the InsituMain™ System, a proprietary system used to rehabilitate drinking water pipelines.

It is expected that Insituform will add accounting staff, project managers, engineers and crew personnel to manage the operations and installations of its projects in Quebec.

“The challenge is simply to raise market awareness for our fully structural CIPP solution and HDPE solution for drinking water and other pressure pipelines,” said Andrew Fulford, the Drinking Water Segment Director for Insituform. He added, “the growing number of customer inquiries we are receiving from across North America validates the demand for a structural alternative to open trench replacement. Insituform is positioned to meet that need through our InsituMain™ System and InsituGuard® product offerings.”

The InsituMain™ System renews pressure pipelines up to 60-inches in diameter. Installed inside an existing pipeline, the InsituMain™ System eliminates the risk of disrupting or damaging nearby utilities or other underground infrastructure systems. The trenchless installation method reduces the social and environmental costs of pipeline renewal projects by minimizing the carbon footprint, site noise, traffic detours and safety concerns present with traditional dig and replace methods.
