The progressive development in urban area has drastically changed land use and deteriorated the quality of source water. The contribution towards higher intensity of rainfall will also increase the problem and affects the quality of water, social and financial situations of the country. The installation of BMPs has been the alternative approach in reducing the effects from rapid urban development. Constructed wetland has been selected under BMPs with the target to enhance the quality of water. It is widely used in developed countries with tropical climate for improving the quality of stormwater. However, constructed wetland is being considered as a new innovation, which is not implemented adversely throughout Malaysia. The main aim of this paper is to evaluate the effect of design criteria on the performance of constructed wetland. Three locations of constructed wetland in Malaysia are selected, which is situated at Putrajaya, USM Engineering Campus and Humid Tropic Center. The selected design criteria are based on the length to width ratio, detention time and average water depth. The results indicated the BOD, COD and TP removal was affected with pollutant removal of 48%, 37% and 64% was noticed. However, TN and TSS analysis showed percentage of removal to be around 74% and 71%.The findings can be significantly used to enhance knowledge in constructing wetland under tropical climate where it can serve effectively for managing urban runoff using control at source approach.
