The aim of this study was to develop a tree box filter system, an example of Low Impact Development technology, for
treating stormwater runoff from road. Monitoring of storm events was performed between June 2011 and November 2012 to
evaluate the system performance during wet day. Based on the results, all runoff volume generated by rainfall less than 2
mm was stored in the system. The minimum volume reduction of 20% was observed in the system for rainfall greater than
20 mm. The greatest removal efficiency was exhibited by the system for total heavy metals ranging from 70 to 73% while
satisfactory removal efficiency was exhibited by the system for particulate matters, organic matters and nutrients ranging
from 60 to 68%. The system showed greater pollutant removal efficiency of 67 to 83% for rainfall less than 10 mm
compared to rainfall greater than 10 mm which has 39 to 75% pollutant removal efficiency. The system exhibited less
pollutant reduction for rainfall greater than 10 mm due to the decreased retention capacity of the system for increased
rainfall. Overall, the system has proved to be an option for stormwater management that can be recommended for on-site
application. Similar system may be designed based on several factors such as rainfall depth, facility size and pollutant
removal efficiency.
