200 Insituform Employees Take Action for Clean Water On World Water Day 2008.

Insituform CEO Calls for Increasing Global Access to Water And Repairing Deteriorating Infrastructure

CHESTERFIELD, Mo. -- Almost 200 employees of Insituform Technologies, Inc. (Nasdaq Global Select Market: INSU) from 10 countries and 20 states are lending their voices to a call for action on the global clean-water crisis on World Water Day, March 22, 2008.

From Europe and Asia and every corner of North America, Insituform employees are supporting the United Nation's World Water Day by participating in "Walk for Water" activities. Scores of Insituform employees signed up online to either participate in the walks in several cities across the United States - such as New York, Seattle, or Los Angeles - or to join in a "virtual" walk. In the virtual walk, participants in actual walks will carry Insituform employees' names in symbolic water jugs during the event. The walks recognize the daily journey that women and children in many countries are forced to make to get water for their families.

"Insituform and our employees are focused not only on the 1.1 billion people - one-sixth of the world's population - who lack access to clean water, but also on the rapidly deteriorating infrastructure that delivers clean water to people fortunate enough to live in developed countries," said Al Woods, Insituform Interim Chief Executive Officer. He said that, while many people struggle to get the minimal amount of clean water necessary to live, others are facing the collapse of the system that delivers clean water to them as well as the sewer system that protects their water from contamination.

Woods noted that not only is March 22 the United Nation's annual World Water Day, but also that the U.N. has declared 2008 the International Year of Sanitation. "These two issues are inextricably linked and are essential for improving the world's health and economic development," Woods said.

He said the lack of clean water exacts a terrible toll on human life around the world. "Water-borne illnesses are the No. 1 cause of sickness and death in the world. They kill 2.2 million people a year - 6,000 children every day," he said.

Woods said Insituform is working to help the water industry develop a closer partnership with municipal officials and financial leaders to promote progress in the clean-water effort. He said Insituform's leaders have spent much of the last year discussing water and sanitation challenges with leaders from the Asia-Pacific region and Europe and across North America.

"We urge everyone to work together to find solutions to the clean-water challenges we face across the globe," Woods said. "We believe the charge we have taken upon ourselves to enable 'clean water for the world' is a noble cause that leaders everywhere can support. There are promising signs of increasing attention to the lack of clean water by national, international, and financial leaders around the world. We can provide or repair the infrastructure needed to address this global water crisis if we work together."

Matt Wassam, National Sales Manager for Insituform Blue[TM], the company's potable water division, said many water and sewer systems are aging beyond their life expectancy. In an Advocate's Page he created on the World Water Day Web site, Wassam said, "Sustainable water ... requires the taxpayers, public works officials, and legislators to continue to invest in treatment and infrastructure." Allowing the infrastructure to crumble before addressing it, Wassam said, is "like driving a car 40,000 miles before changing the oil."
