The aim of this study was to evaluate the influence of the city of \303\226rebro, where it is no com-bined sewers, on pollution load to the receiving water the river Svart\303\245n. GIS and hydrologic modelling was used to achieve this. The subcatchments in the city that accounted for the highest discharges of pollutants was identified and measures to reduce the load from these subcatchments was proposed. It was shown that stormwater was the most important source of heavy metals to Svart\303\245n, but the influence of stormwater on the nutrient load was negligible. Further, one stormwater discharge was identified that accounted for about 1/4 of total pollu-tion load from storm-water on Svart\303\245n. Even if this subcatchment yielded the highest amount of pollutants, the highest concentrations was found from small homogeneous catch-ments. It was concluded that studies like this could be a valuable tool in the stormwater management.
