Abstract
Filter drain is one of In-ground SUDS, and this dissertation is a study of its performance in the control of urban runoff from both quantity and quality aspects. For this purpose a filter drain was therefore designed and constructed at an outdoor site located on Scottish water-owned land at riverside drive at Dundee airport. Determined pollutants loads including builder’s sand as sediment loading, petroleum hydrocarbons, metals (Cu and Zn) and polycyclic aromatic hydrocarbons were used for the purpose of this study. Effluent samples were taken and analyzed and the percentage of removal was then calculated. This assessment measures the ability of filter drain in removing the above pollutants from the drainage route. 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 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 was greater than 99%. The upper results shows that the filter drain is an effective trap system as it was able to retain of builder’s sand with heavy concentrations. No clogging result during the test runs. The constructed filter drain was effective in attenuating water flow with a mean flow reduction rate of about 95%.
