Center-pivot irrigation can lead to increased withdrawal rates from the Ogallala Aquifer due to the high water demand of this type of irrigation system. The aquifer may experience depletion and reduced water levels over time as a result of excessive pumping for center-pivot irrigation. Sustainable water management practices are important to mitigate the impacts of center-pivot irrigation on the Ogallala Aquifer.
It has a pivot point
it is called the "center"

The center of a seesaw is called the "fulcrum." It is the pivot point around which the seesaw moves up and down.
If you put a 300 gram weight in the center on the pivot, the pivot is already balanced because it has the same amount of grams on each side. Therefore, another 50 gram weight would not help to create balance.
A center pivot irrigation system typically uses around 0.5 to 1.0 kilowatt-hours of electricity per acre-inch of water applied. The exact amount of electricity used can vary depending on factors such as the size of the pivot, the length of time it operates, and the efficiency of the system.
