In order to decrease the production costs of small farmers - the participants of irrigation district, the possibilities to save electrical energy are: (i) sizing the water pumping systems; (ii) adopt the electric motive power, and (iii) management of the water use. The experiment was conducted in the Miroros Irrigated Perimeter, located in Ibipeba, Bahia, Brazil. The study was done on the pressurization station 1, where two out of four motor pump sets were analyzed. The process of energy optimization used includes the pump and electric motor dimensioning and the evaluation of the pump-motor set. The global savings potential with the motor pump Set1 was around 8.75% and for the Set 2 was around 31.6%. It was observed as well, that the greater the load index (ratio between the actual load and the rated power) smaller would be the water charges. In order to achieve the desired savings in the water use management, measures are to be implemented to stimulate simultaneous water use by the farmers.
