Description:
Renewal technologies currently being used for the repair, replacement and/or rehabilitation of deteriorating water distribution systems are generally effective, but there is still considerable room for improvement of existing technologies and for the development of new technologies. Many utilities are seeking innovative rehabilitation technologies as a way to extend the life of their water distribution systems; however, information about these emerging technologies is not always readily available. As part of the U.S. Environmental Protection Agency (EPA)’s Aging Water Infrastructure Research Program, one of the areas of research being pursued, in collaboration with water utilities, is a field demonstration program of emerging and innovative rehabilitation technologies. The purpose of this program is to (1) gather reliable performance and cost data during the application of these technologies at selected sites and (2) to make the capabilities of these technologies better known to the industry. This paper describes the demonstration of an innovative, semi-structural, spray-on lining for rehabilitating 1,330 feet of 10 inch cast iron water main in Somerville, NJ. The demonstration included the installation of a 6 feet section of cast iron pipe containing field prepared defects, as well as a 6 feet section of ductile iron pipe containing lab prepared defects, to examine the spanning capability of the spray-on lining.
