Bioretention is a new technology for urban storm water management in Malaysia. Universiti
Tenaga Nasional (UNITEN) in collaboration with Universiti Sains Malaysia (USM) began
construction of a bioretention system with the expectation that it would become a model of
lot-scale application in Malaysia, as well a pilot learning showcase. The project anticipated to
observe and discover how bioretention systems remove storm water pollutants as no prior
studies on the performance of bioretention systems of this scale have been done in Malaysia.
Guidelines in the Urban Storm Water Management (MSMA), 2nd Edition, are yet to be
proven effective in Malaysia. Therefore, there is an urgent need to learn how bioretention
systems perform so that local design guidelines can be established. A preliminary study was
conducted to determine the types of pollutants in the storm water runoff from a parking lot at
the College of Engineering, UNITEN. After construction of the system was completed in July
2013, water quality measurements were taken. The water quality and flow at the inlet and
outlet were measured and recorded manually as the automatic monitoring system has not
been completed yet. All samples were collected within 24 hours of a monitored storm event.
Preliminary results showed that Total Suspended Solids, Total Volatile Solids, Biochemical
Oxygen Demand, and Chemical Oxygen Demand were effectively removed by more than
80%. Initially, the pollutant load also appeared to have reduced, showing effective
bioretention performance. Further monitoring and analysis will be made to observe
continuing performance and behavior of the system in the conditions typically found in
