Abstract: An irrigation system is constructed from PVC pipe which is tapped into a main waterline buried beneath the surface of the earth. The main waterline is constructed from sections of plastic irrigation pipe having male and female coupling ends, and holes are drilled in the coupled portions of the main waterline pipes so as to permit insertion of water distributing PVC pipes. By drilling the holes in the coupled portions of the main waterline, a double wall thickness is provided for strength into which is insertable PVC nipples which in turn are connectible to PVC risers extending above the ground. PVC emitter pipes may then be connected to the risers through the use of nipples or alternatively, the emitter pipes and risers may be of a unitary, integral construction. A plurality of orifices are provided in the emitter pipes so as to facilitate the distributing of water across the surface of the ground.
