Population growth will result in the increase of water supply demand. Riverbed filtration or radial collector well technique is one of the options for increasing the water supply. Drainage Package of Visual MODFLOW was used for the riverbed filtration modelling. The modelling aimed to identify the optimum pumping rates withdrawal in order to fulfill Lembaga Air Perak requirement for additional water supply. Installation of radial collector wells in the depth of 10-12 m aquifer thickness at Sungai Kampar Perak would increase the supply of clean water for future water demand. The design of riverbed filtration technique consists of 4 m radius of collector well with depth of 10.54 m and five radials wells with 40 m length across the riverbed. Transient condition of the groundwater flow modelling result showed that the optimum pumping rate can meet the water supply requirements of about 35 MLD (35000 m 3 /day).
