Abstract: First flush is the first rainfall after a dry season, which washes out several months of contaminant buildup. Surface runoff from highways can be considered as a critical nonpoint source of water resources heavy metals pollution. In this study, samples of rainfall runoff were collected after the first and second rainfall from a major highway in Sulaimani City and tested for expected Zinc(Zn), Copper (Cu) and Lead (Pb) heavy metals pollutants. Results revealed levels of heavy metals pollution in the highway runoff from the first and second rainfalls which can be considered as heavy metal pollution source for receiving water bodies. After first flush, average test results of heavy metals pollutants were 0.062 part per million (ppm), 0.075 ppm and 0.051 ppm for Zn, Cu and Pb respectively. Low Impact Development (LID) practices found to be a new sustainable stormwater management. Though, the removal of heavy metals from water is costly, consequently, a set of LID techniques are recommended for stormwater treatment as cost effective stormwater treatment for streets and highway runoff treatment. Furthermore, as Sulaimani city uses combined (sanitary and stormwater) sewer system, LID systems can reduce flooding, which makes the treatment of combined wastewater more feasible, improving the quality of receiving water bodies.
