This experiment was carried out at Unit I at the Federal Technological Education Center in Uberaba (CEFET-Uberaba-MG), during the year of 2006. The objective was to evaluate the influence of solids concentration in swine wastewater on head losses of the irrigation system, on water distribution uniformity, on distribution of solids along the sprinkler radius of throw, pump efficiency and horsepower required by the pump at the electric system. The treatment levels were solid concentration at different depths of a wastewater in a stabiliztion pond. The irrigation self propelled system was manufactured by Metal Lavras, model mini 63/150, with a gun sprinkler model Plona RL 250 and a pump system with a Schneider unit model MSA-22R 1/14" with a three phase electrical engine 15 HP. The experimental design was randomized blocks with tree replicates. The head losses were influenced by the solids concentration increasing the losses in 30,12% at the main pipe, 11,93% at the turbine and 20,55% at the plastic hose, for the largest solid concentration compared to water only. The water distribution uniformity and radius of throw no statistical differences were observed for water distribution uniformity and radius of throw. It was observed that solids application varied along the radius of throw, being larger quantities applied at the larger distances. Pump efficiency was affected by solid concentrations, being reduced as much as by 9% for the largest solid concentration. The horsepower required was also influenced by the solid concentration of 34168 mg L-1, being increased in 8,28% when compared to pure water.
