Impact/Purpose:
As trenchless technologies have continued to develop and improve over the past 40 years, the average rate of system renewal is still not adequate to keep up with the increasing needs of utilities. To meet that need, many wastewater utilities are seeking innovative trenchless technologies to repair larger portions of their systems. However, information on emerging technologies is not always easy to obtain. The need for independently verified information on emerging technologies has been a focus of U.S. Environmental Protection Agency through its Aging Water Infrastructure since 2007. The U.S. EPA created an innovative technology demonstration program to demonstrate and evaluate the performance of emerging technologies under actual field conditions.
Description:
While sewer renewal technologies currently being used for the repair, replacement and/or rehabilitation of deteriorating wastewater collection systems are generally effective, there is still room for improvement of existing technologies and for the development of new technologies. Many utilities are seeking innovative rehabilitation technologies, particularly for large-diameter pipes; however information about these emerging technologies is not always readily available. This paper describes the demonstration of an innovative, spray-applied, fiber-reinforced geopolymer mortar for rehabilitating a 60-in. reinforced concrete pipe approximately 25 ft deep in Houston, TX.
