Abstract:

This paper presents a study of the application of the theory of rainwater harvesting for a low income flat in West Jakarta. The background of this study is that Jakarta as a capital city of Indonesia is actually experiencing water crisis because of the rapid population growth and the building construction. This rapid development in consequence affects a reduction on the ground water supply. Therefore, this study analyse the amount of rain water that can be an alternative water supply particularly for a low income flat. This study focused on the water supply for the flushing toilet. To accommodate that objective, a brief calculation of water catchment area and the amount of water that can be harvested has been conducted. The results showed that in general the water supplied by the rain water harvesting can provided 100% annually, but since the precipitation in August is relatively low, in consequence, the water suply should be provided by the local government water company (PDAM).
