Abstract	Over the past a few years, there were numerous inquiries from municipal engineers on the costs of rehabilitation or construction of buried pipes using trenchless technologies, This report was prepared to provide this cost information. The cost data of trenchless rehabilitation and construction projects from various sources were collected, compiled and presented. The data indicate that, in general, costs of the trenchless methods increase with the increase in pipe size. Costs of emergency repairs are more than 3 times the normal repair average. Costs of some maintenance activities are included, as well as costs of the available internal inspection and evaluation methods. Furthermore, cost ranges for access hole rehabilitation, replacement and new construction are summarized.
