The design of pipe system for water supply through buried pipes and for efficient irrigation, it is necessary to know the hydraulics of the pipe systems. The hydraulics of the buried pipe distribution system consists of flow of water in the pipe, frictional head loss, other fitting losses, velocity, etc. The material selected for water distribution system is made of PVC pipes confirming to the Bureau of Indian Standard Specifications IS:4985, 1981 (as amended from time to time) or the standard prescribed by other national standard organization. The procedure, in the design consists of deciding the pipe diameter for different discharges and for different area of the plot. The design also consists of pressure tolerance of the pipe system. The long history of hydraulics of the pipe system is referred. The extension of reviewed paper is presented. In designing the pipe system, the hydraulics of pipes plays the major role in the contest of hydraulics.
