Irrigation sprinkler is a device which is used for irrigation of lawns or crops. It is usually used on farms, golf courses, and yards, to provide water to vegetation and plants in the event of drought. They may also be used for recreation, as a cooling system, or to keep down the amount of airborne dust. Home lawn sprinklers vary widely in their size, cost, and complexity. Small sprinklers are available at home and garden stores for small costs. These are often attached to an outdoor water faucet and are placed only temporarily. In Littleton these sprinklers can be fixed with spray heads that have a set pattern and generally spray between 1.5-2m, full rotating sprinklers that can spray a broken stream of water from 6-12m, or small drip emitters that release a slow, steady drip of water on more delicate plants such as flowers and shrubs.
