The Roman aqueducts are often mentioned as examples of great technical achievement indeed some of these early structures are still in use today. Although most of the early water carrying structures were open channels conduits and pipes of various materials were also used in Roman times. It appears though that the effectiveness of the early pipes was limited because their materials were weak in tensile capacity. Therefore the pipes could not carry fluid under any appreciable pressure. Beginning in the 17th century wood and cast iron were used in water pipe applications in order to carry water under pressure from pumping which was introduced about the same time. Since then many materials have evolved for use in pipes. As a general rule the goals for new pipe material development has been increased tensile strength reduced weight and of course reduced cost. Pipe that is buried underground must sustain other loads besides the internal fluid pressure. That is it must support the soil overburden groundwater loads applied at the ground surface such as vehicular traffic and forces induced by seismic motion. Buried pipe is therefore a structure as well as a conduit for conveying fluid. That being the case special design procedures are required to insure that both functions are fulfilled. It is the purpose of this chapter to present
