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 aim was to evaluate the influence of solids concentration in swine wastewater on charge losses of the irrigation system, on water distribution uniformity, on distribution of solids along the sprinkler radius of throw. The treatment levels were solid concentration at different depths of a water pond. The irrigation self propelled system is 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 charge losses were influenced by the solids concentration increasing the losses in 30.77% at the main pipe, 13.59% at the turbine and 22.02% at the plastic hose, for the largest solid concentration compared to water only. At water distribution uniformity and radius of throw statistical differences were not observed. One observed that solid application varied along the radius of throw, being larger quantities applied at the larger distances.
