Center-pivot irrigation (sometimes referred to as central pivot irrigation), conjointly referred to as water-wheel and circle irrigation, may be a technique of crop irrigation during which instrumentation rotates around a pivot and crops square measure moire with sprinklers. 

Most center pivot systems currently have drops hanging from a formed pipe referred to as a curved shape hooked up at the highest of the pipe[clarification needed] with mechanical device heads that square measure positioned many feet (at most) on top of the crop, so limiting phase transition losses and wind drift. There square measure many alternative nozzle configurations offered as well as static plate, moving plate and half circle. Pressure regulators square measure generally put in upstream every|of every} nozzle to make sure each is working at the proper style pressure.

Center pivot irrigation may be a kind of overhead mechanical device irrigation consisting of many segments of pipe (usually galvanized steel or aluminum) with sprinklers positioned on their length, joined along and supported by trusses, and mounted on wheeled towers.The machine moves during a circular pattern and is fed with water from the pivot purpose at the middle of the circle.

For a middle pivot to be used, the parcel has to be fairly flat; however one major advantage of center pivots over different systems that use gravity flow is that the ability to operate in undulating country. This advantage has resulted in raised irrigated area and water use in some areas. 

Center pivots square measure generally but 1600 feet (500 meters) long (circle radius) with the foremost common size being the quality 1/4 mile (400 m) machine. A typical 1/4 mile radius crop circle covers concerning one hundred twenty five acres of land[8]
