A flood is a disaster with such highly negative impacts on the loss of life and property that it has to be mitigated. In this regard, the present research aims to: measure the rainfall volume that causes flood and analyze the efforts of reducing the flood volume caused by rainfall in the Region of Jakarta. An experimental method was applied to measure rainfall and run-off volumes stored in infiltration wells. The research was conducted in the following stages: analyzing land use and analyzing rainfall and surface runoff volumes. We found that changes in land cover negatively affect the land’s abilityto absorb rainfall. Land cover formed by vegetation will be different from impermeable land cover, such as houses, offices, pavements, and hotels. To reduce potential flood is achievedby reducing the surface runoff volume. Meanwhile, in order to reduce the runoff volume, an infiltration well that can accommodate 5m 3 of water can be constructed for every 100m 2 of developed area. With a number of 664,701,800 infiltration wells, as much as 3,323,509m 3 of rainfall volume can be collected in those wells. Finally, with these infiltration wells, the Special Capital Region of Jakarta will be free of flood. Keywords: Rainfall; Flood; Land cover; Impermeable layers; Infiltration wells
