Abstract

The rapid development in an urban area can drastically change the land use and deteriorate the quality of
source water. The contribution of higher intensity of rainfall will also worsen the problem and affect the quality of water.
Constructed wetland is an essential component in improving the quality of stormwater and as an alternative method to
reduce flood in urban area. It has been widely used in developed countries and temperate climate for the stormwater
quality improvement. However, in Malaysia it can be considered as a new innovation and has not been widely
implemented nationwide. The aim of this paper is to evaluate the function of constructed wetland in tropical climate as
stormwater quality improvement with the experience from three constructed wetlands situated in Penang, Selangor and
Kuala Lumpur in Malaysia. The data collected from these wetland systems used to treat stormwater runoff or runoffimpacted
surface waters were examined and compared in order to identify any obvious trends that may aid future
stormwater treatment wetland design efforts. The parameters measured and discussed in this paper are Total
Phosphorus (TP), Biological Oxygen Demand (BOD), Total Nitrogen (TN), Total Suspended Solid (TSS) and Chemical
Oxygen Demand (COD). The results indicate that the mean pollutant removal for BOD ranged from 8.73% to 39.03%,
COD ranged from 11.74% to 27.66%, TSS ranged from -72.70% to 73.64%, TP ranged from 1.32% to 57.69% and TN
ranged from 3.50% to 70.56%. The findings also indicate that the mean outlet concentrations for BOD, COD and TSS
comply with the Water Quality Index Class II, thus far, partially fulfil the government’s policies. Findings from this study
can be used significantly to enhance the knowledge in constructed wetland under tropical climate where it can serve
effectively for managing urban runoff using control at source approach.
