Abstract

Construction, vehicular traffic and maintenance of highway surfaces are sources of  pollutants, which accumulate on highway surfaces and other roadside areas. During rainfall runoff events these pollutants are washed from these surfaces and flow to surface and  subsurface waters. This research is a study to assess the ability of a constructed filter drain as  one of Sustainable Urban Drainage Systems (SUDS) in removing suspended solids,  petroleum hydrocarbons, metals in the form of Copper and Zinc and polycyclic aromatic  hydrocarbons were used for the present study from urban runoff. The constructed filter drain  was successful in controlling, attenuating and treating runoff containing  pollutant loadings of  (sediments, petroleum hydrocarbons, metals and polycyclic aromatic hydrocarbons). For the  eight stimulated test runs, the average removal rate of the builder's sand as sediments was  97%. The average total petroleum hydrocarbon removing rate was 97 .8%. The mean copper  (Cu) and zinc (Zn) removing rate was 82% and 92% respectively. The average removing rate  of polycyclic aromatic hydrocarbons
