Rapid development needs a new paradigm in the context of preparing the urban drainage system in Malaysia. This could be achieved with the implimentation of Manual Saliran Mesra Alam (MSMA). MSMA provides guidelines in controlling the quantity and quality of stormwater as the main agenda for drainage system in urbanised areas.
Bio-Ecological Drainage Systems or BIOECODS is a pilot project in USM Engineering Campus as a result of a smart partnership between Universiti Sains Malaysia and Department of Irrigation and Drainage (DID) Malaysia.. It is one of the alternatives listed in Urban Stormwater Management Manual For Malaysia to create an environmentally friendly development. This new environmental-friendly system is based on "Control-at-Source" concepts combining infiltration, detention storage, conveyance to attenuate stormwater runoff. The removal of pollutant is obtain through a series of best management practises which provide treatment of the runof as it moves from the source to the stream. Water that had been treated can be use again or recycle through a few of detention storages which is designed as wetpond or recreational pond.
