+is study focuses on identifying and evaluating critical parameters of various drainage con0gurations, arrangement, and 0lter which a1ect the e2ciency of water draining system in slopes. +ere are a total of seven experiments with di1erent types of homogeneous soil, drainage envelope, 0lter material, and quantity of pipes performed utilizing a model box with a dimension of 0.8 m × 0.8 m × 0.6 m. +e pipes were orientated at 5 degrees from the horizontal. Rainfall event was introduced via a rainfall simulator with rainfall intensity of 434.1 mm/h. From the experiments performed, the expected outcomes when utilizing double pipes and geotextile as envelope 0lter were veri0ed in this study. +e results obtained from these experiments were reviewed and compared with Chapter 14 “Subsurface Drainage Systems” of DID’s Irrigation and Agricultural Drainage Manual of Malaysia and the European standard. It is recommended that the pipe installed in the slope could be wrapped with geotextile and in tandem with application of granular 0lter to minimize clogging without a1ecting the water discharge rate. Terzaghi’s 0lter criteria could be followed closely when deciding on new materials to act as aggregate 0lter. A caging system could be introduced as it could maintain the integrity of the drainage system and could ease installation.
