Abstract
Traditional storm water management practices mainly rely on conveyance to route storm water runoff from urban impervious surfaces into the nearby natural water bodies. Dedicated facilities are designed to reduce storm water runoff pollution and/or mitigate the effects of the increased runoff peaks, volumes, and velocity. More recent concepts in urban storm water management, such as better site planning techniques and Sustainable Urban Drainage Systems (SUDS) or Low-Impact Development (LID) technologies including green roofs, focus on the use of both planning techniques and micro-scale integrated landscape-based practices to prevent or reduce the impact of storm water runoff at the very point where these impacts would be initially generated. The objective of this study is to evaluate the performance of MSMA SME bioretention component at HTC to reduce peak discharge and improve water quality under the influence of high intensity rainfall in tropical climates. The rainfall, hydrological and water quality data were analyses and the outcomes of the final analysis are compared to improve the performance and choosing the best system to be implemented in HTC KL. In conclusion, the bioretention is effective in treating runoff and by almost breaking down the pollutant to class II, overflow from the bioretention can only be generated for storm with enough intensity and long duration and the size of the bioretention is not suitable for catchment area.
