Irrigation systems have to be properly designed with a reasonably uniform water application with assurance of return of the capital invested, because their initial cost is very high. Another point to be studied is the management of the system. For instance, flow or pressure regulators are used to obtain within reasonable limits uniform applications of water from all the sprinklers operating in a field. They can overcome the problem of excessive pressure-head variations resulting from sloping surfaces and pressure-head losses. In consequence, mainly the sprinklers and sprays must be changed when they are out of order or lost the efficiency. This is the main objective of this study: to evaluate the installed center pivot system and make the essential changes and modifications for obtaining higher efficiency.
