Sprinkler irrigation is a way of artificially wateringplants. A sprinkler irrigation system is a pressurized system, which means it needs water under pressure to work.
The system is made of a pump to take water and create pressure, and a network of pipes leading to the sprinkler head, which spreads water over the plants. Usually the sprinkler head is erected upward on a riser, which is a small pipe (about half a inch in diameter and one meter high). The sprinkler head is a simple-designed device composed of a hammer and a spring, both operates together to cut the water stream outgoing from the nozzle into small bits of water. These are spread over a circle of plants called the diameter of coverage.
