Profiling the implementation of rainwater harvesting in Bekasi, Indonesia

Abstract

Abstract This research was raised based on water resource problems, which are currently becoming a global obstacle to overcome. Population growth impacted the demand for water resources, changed the hydrological cycle pattern in an area, and worsened with climate change, impacting season disaster. This research was conducted to see the profile of Bekasi City on rainwater harvesting so that the results of this study are expected to provide a big picture in the context of applying rainwater harvesting. Rainfall analysis uses dependable rainfall to cut down rainfall uncertainty and grant opportunities for a higher harvestable rainfall volume. Besides, a community approach was carried out to observe society’s water use patterns and their behavior towards rainwater harvesting. This study found that the volume of water demand in Bekasi varied in each District, which is 3.57-7.08 m3/person/month, and harvested rainwater can cover up 2.27%-12.73% of their needs during the wet season (December-April). The community has collected their rainwater at their homes by 49%. A comprehensive approach should have taken to attract people to harvest rainwater.
