Street weeping is an interesting non-structural method to decrease the pollutant load to stormwater. In this paper a study of street sweeping performance is presented. A test section of a street was swept once a week during three weeks and once every workday during another three week period. The amount of removed sediment was measured and the sediments were measured for heavy metals. During the test period 84.5 kg of sediment was removed from the street, which corresponds to 4 g of copper and zinc, 0.9 g of chromium, 0.6 g of lead and 0.4 g of nickel. During the everyday sweeping period the amount of sediment in the street decreased exponentially and approached a steady state condition. The weather during the period was dry, which meant that the effect of the street sweeping on the stormwater quality could not be measured.
