Abstract

Bioretention systems, also known as rain gardens, are part of the Urban Storm Water
Management Manual for Malaysia (MSMA). In Malaysia, bioretention is recommended;
however there is no performance data available for field scale installations. Bioretention are
the simplest form of Water Sensitive Urban Drainage (WSUD) systems which has the
potential to contribute towards sustainable development. In addition, bioretention are
designed to receive storm water runoff from impermeable surfaces such as roads, parking lots
and roofs and it is effective in retaining large volumes of runoff and consistently reducing the
number of certain pollutants via biological uptake and porous media filtration processes,
combined to treat storm water runoff. The shallow dish design was intended to capture and
treat runoff from small catchments limited to less than 1.0 ha of impervious area. This paper
aims to report an evaluation of a bioretention system established in the Humid Tropics Centre
(HTC), Kuala Lumpur as one of the components of the MSMA Storm Water Management
Ecohydrology (SME) Project. The hydraulic conductivity of the filter media was monitored
and showed improvement from 62.15 mm/hr to an average of 337.48 mm/hr. Grab samples
collected during storms were sent to a certified analytical laboratory for water quality
determination and were found to have Water Quality Index close to Class I or Class II
readings. Bioretention system at HTC Kuala Lumpur is considered as a new application and
has the potential to lead the way to improved storm water management in urban areas.
