A rehabilitation system has been developed for cleaning, testing and slip lining pipe particularly sewer lines while in service. The system includes the use of equipment adapted for use on mobile vehicles to increase efficiency and mobility of the system. The cleaning system utilizes a specialized cleaning bucket that can be pulled from excavations and existing manholes. The testing and lining systems also utilize specialized test mandrels and pulling mandrels for the pipe liner that can be used with equipment operating, in part, from existing manholes.
