Abstract

Indonesia is a country that has large rain water availability. However, the implementation of rainwater harvesting in urban areas has not become a popular activity in Indonesia. Instead of the ignorance of the public about the importance of rainwater harvesting as an alternative source of freshwater, information and knowledge about the construction of the installation of rainwater harvesting systems is still very limited. This paper aims to analyze supporting capacity of rainwater harvesting for domestic needs in Bandar Lampung city, Indonesia. This paper also aims to introduce a real experience in rainwater harvesting at household scale in the city. Rainwater harvesting simulation is applied to a family with a roof area of 70 m2 with number of family members 5 persons and maximum storage capacity 1.2 m3. Daily rainfall data used in the simulation is obtained from Bandar Lampung Raingauge Station with period of data from 1992 to 1996. The simulation shows that supporting capacity of rainwater harvesting in the area of study is about 53% and 42% for wet year and dry year, respectively. Experience also shows that knowledge about the operation and maintenance of rainwater harvesting facility is important in the application of rainwater harvesting at household scale.
