The urban drainage network is among the main pollution transport load factors. Researches on the identification of solid waste transported in the drainage network have been considered the allow evaluation of its impact. In this paper we analyze the main characteristics that influences the presence of solid wastes in the drainage network of the Rio do Meio basin, Florianópolis/SC. A metal net was installed in selected river section and monitored after each rain event. The results showed about 0.27 kg/ha.year of waste are carried in the drainage network. The majority being composed of plastics and building materials. Through the analysis of the data, it was possible to verify the presence of waste in the drainage network is due to poor packaging and to the lack of sweeping in some parts of the basin. It was also found that the total precipitation is directly proportional to the appearance of solid waste. It was concluded that the lack of an integrated management between the components of sanitary system leave unnoticed simple structural measures that ultimately decrease the amount of solid waste in the drainage basin, and that could eliminate this source of pollution.
