Irrigation of turfgrass is the artificial provision of water, both subsurface and overhead, through pipes, canals, and flooding, using either a fixed or movable supply system. The most common form of turfgrass irrigation involves small orifice emitters in sprinkler heads flush at ground level, connected to a pressurized pumping system by means of rigid pipes. Drainage is the artificial removal of water through subsurface pipes, lateral ditches, siphoning, and grading.
