Abstract: An important aspect to be considered in irrigation managment is the uniformity distribution of water through the irrigation system. This research had the objective to evaluate the efficiency of chlorination in the use of sodium hypochlorite in clearing of microsprinkler due to the presence of high iron concentration in water. The equipment with less than a year of use presenting sectors with 5% and 57% lower flow than the original project flow. The chemical treatment of water irrigation utilized sodium hypochlorite with 12% free chlorine on 100mg L-1 concentration, and sulphuric acid 98% to maintain the pH of water irrigation about 4.5. The result demonstrated a significant increase in the average flow of the microsprinkler's variation in all evaluted setors, and decrease in their flow variation related to the estimated in the project.
