| Resumo: | Malaysia as a country which received a very high rainfall throughout the year is moving towards adopting rainwater
harvesting system (RWHS) as a means to mitigate water shortage and flood problem. In 2012, RWHS is made
compulsory for every development of new housing and building at several states in Malaysia, both for water supply
and flood control. Furthermore, since flood is becoming more prevalent nowadays in Malaysia especially in
Kuantan, Pahang, lacks of space for the construction of flood mitigation facilities has prompted authorities to look
for other solutions for flood control. This study intends to determine the potential of rainwater harvesting site in
Kuantan, Pahang. Daily rainfall data from six selected hydrology stations in Kuantan catchment are used to analyse
the water availability in order to identify the potential of rainwater harvesting site in Kuantan. The highest amount of
rainfall received by all stations for five consecutive years is on December except for two stations recorded highest
amount of rainfall on January in year 2011 and three stations recorded highest amount of rainfall on February and
May in year 2013. Meanwhile the least number of rainfalls received by all stations for five consecutive years varies.
