Abstract
The aim of this study was to determine the specific water quality characteristics of stormwater constructed wetlands treating stormwater road runoff in a tropical climate. Four representative constructed wetlands were selected as study sites in the peninsular Malaysia. Runoff samples were randomly collected from each site twice every week. The samples were analysed onsite for pH, Dissolved Oxygen (DO) and Temperature. The samples were then transported to a laboratory at the University of Nottingham Malaysia Campus for further analysis of nitrate-nitrogen and orthophosphate-phosphorus, selected haevy metals such as nickle and copper,biochemical oxygen demand (BOD), solids and microbial contamination by E.coli and intestinal enterococci. The water samples were collected over a period of 12 months from January 2015 until December 2016. Water quality evaluation of the four representative sites through physical, chemical and biological analysis indicated high removal effficiencies compared to published literature. The role of plant (Eleocharis dulcis and Scirpus mucronatus) in removing nitrogen and phosphorus from was also assessed. An analysis of variance revealed that some one the representative sites showed significant diffrences in terms of water quality indicators. The other three sites showed similar water quality charcteristics. This was then associated with the choice of plant species.
