This diagram depicts the most common type of sprinkler system layout. Sprinkler system design consists of a network of lightweight aluminum or plastic pipes moved by hand. Rotary sprinklers are typically spaced 9-24 m apart along a lateral of 5-12.5 cm in diameter. This is done to make it easier to transport. A sprinkler irrigation system is a method of watering your farm that works similarly to normal rainfall. Pumping is used to move water through a network of pipes. It is then separated by sprinklers, resulting in tiny water drops that fall to the ground.
