Insituform Receives Contracts Valued at US $19.9 Million to Rehabilitate Wastewater Pipelines in Singapore

Insituform Technologies, Inc. (Nasdaq Global Select Market: INSU) announced today that its Singapore subsidiary, Insitu Envirotech (S.E. Asia) Pte Ltd. ("Insituform”), has been awarded four contracts totaling US $18.5 million. Under the contracts, Insituform will perform work for the Public Utility Board (PUB), Singapore’s national water agency, and rehabilitate approximately 50 miles of sewer pipeline though the use of the Insituform® cured-in-place pipe (CIPP) process. Insituform also announced it has received an additional US $1.4 million in orders to supply CIPP tube to third parties in Singapore. For the year, Insituform has received approximately $3.1 million in third-party, CIPP tube sale orders.

In 2009, PUB, Singapore’s publicly-owned water utility, began work on a multi-year US $295 million rehabilitation program. This rehabilitation program is expected to be completed in 2014 and will upgrade over 700 miles of public sewers and 30 miles of pumping mains. PUB serves a population of over 4.5 million Singaporeans. These contracts are part of PUB’s ongoing rehabilitation program.

"Insituform looks forward to continuing its work with PUB and to the opportunity to bid on additional work as PUB continues its ongoing rehabilitation program. In addition, we continue to provide enhanced services to the market in Singapore by supplying local rehabilitation contractors with our CIPP tube. We expect to continue this offering by supplying CIPP tubes for PUB projects for many years to come,” said Daniel Cowan, Insituform’s Vice-President, Asia-Pacific.

The iPlus Infusion^® system for small-diameter wastewater pipelines and the iPlus^® Composite system for medium- to large-diameter wastewater pipelines will be used for the first time in Singapore on this project. These next-generation CIPP solutions provide PUB with an environmentally beneficial solution. Insituform plans to utilize its air invert steam cure (AISC) technology to complete this project, which will reduce water and energy usage on the job site by approximately 95 percent.

Insituform expects this project will create 45 new positions including laborers, field management and administrative personnel in Singapore. In addition, locally-owned subcontractors will be used to complete work on this project, which is expected to begin in March 2010 and be completed by December 2011.

"Singapore’s PUB is one of the most progressive water utilities in the world. This project, which is Phase IV in its overall sewer rehabilitation program, allows Insituform to introduce its next-generation solutions to Asia. We remain committed to partnering with PUB to ensure it can continue to meet its customer demands. By utilizing our innovative technology, PUB will be able to upgrade its system with little disruption to the people of Singapore,” Cowan continued.
