Rainwater as a potential alternative source of water in Tanjong Malim, Perak

Clean water resources play an important role in meeting the daily needs of human life. Lack of water resources and supply is highly associated with natural factors as well as the increased water pollution due to rapid development. Dependence on the system of water supply from the river solely affects the increasingly diverse needs of the community in Malaysia. As Malaysia receives a high rainfall throughout the year, relying on rainwater harvesting as an alternative water source should be given due attention. Thus, a study regarding the potential of rainwater as an alternative source of water for domestic use has been conducted in Tanjong Malim, Perak. Assessment is made on the annual rainfall trend for the last 40 years to see the long-term resource capacity and water quality tests were conducted to identify the level of cleanliness of water for domestic use. Based on this study, Tanjong Malim generally receives a high annual rainfall of over 2400mm per year since 1960 and it is most suitable for collection as an alternative to water resources. With this finding, it is hoped that members of the community can focus on making rainwater resource as an alternative source of water supply as well as save money on utility bills.
