||Renewal technologies 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 these existing technologies and for the development of new technologies. Many utilities and municipalities are seeking innovative rehabilitation technologies as a way to extend the life of their water distribution systems; however, information about these emerging technologies is usually not readily available. As part of the U.S. Environmental Protection Agency (EPA)'s Aging Water Infrastructure Research Program, one of the key 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 report outlines the demonstration of the 3M(Trade Mark)Scotchkote(Trade Mark)spray-in-place pipe (SIPP) 269 product undertaken in Somerville, New Jersey for New Jersey American Water. The product is a polyurea, which has a faster cure time compared to polyurethane and epoxy linings. The field demonstration allowed an evaluation of the main benefits claimed and limitations cited by 3M(Trade Mark)for this emerging spray-on lining technology. The demonstration of the 3M(Trade Mark)Scotchkote(Trade Mark)SIPP 269 product in Somerville, New Jersey ultimately resulted in a liner failure. The liner failure had a positive effect in discovering the product was not robust enough for use in typical in situ water main conditions, leading to its removal from the market. The removal of the product from the market also led the American Water Works Association (AWWA) Polymeric Lining Standards Subcommittee to put its standard development on hold pending the development of a product with a reasonable track record of success. 3M(Trade Mark)is currently developing a new formulation for a semi-structural spray-on lining application.
