Abstract: The Department of Irrigation and Drainage Malaysia has produced on Urban Stormwater Management Manual for Malaysia or better known as Manual Mesra Alam (MSMA) to that includes suggestions on implementing infiltration method for controlling the quantity and quality of surface runoff. With this method, the volume of surface runoff can be reduced and flood problems in major cities can be eliminated. The study areas, Butterworth and Universiti Sains Malaysia (USM) Engineering Campus are located in the middle and south part of Seberang Perai, Pulau Pinang in the northwest corner of Peninsular Malaysia. Both area of studies have a different state of development, where Butterworth is undergoing rapid development and the USM Engineering Campus is a newly completed development with control at source drainage system. Thus, the paper will describe the analyses of the infiltration curves for both Butterworth and USM Engineering Campus. The resulting infiltration maps have developed based on the infiltration capacities.
