The article discusses the replacement project of a vitrified clay pipe (VCP) in Salina, Kansas. The design, plans and specifications were developed by utility engineer Steve Palmer and Salina director of utilities Martha Tasker. It notes that the pipe reaming process is a combination of an assemblage of the power and versatility of a horizontal directional drill and a modified back reamer. The mechanics of the construction procedure is also explained.
