<![CDATA[Continuous development causes changes in land use from open spaces as water catchment areas to become residential areas. The change in function of water catchment land causes rainwater that falls on the land not to enter the soil, but overflows on the surface of the soil. During the rainy season, most of the water will be discharged directly into the sea, otherwise it will cause puddles and flooding. Meanwhile, during the dry season, many groundwater sources experience drought. Naturally, groundwater shortages can be overcome if the management system is handled properly.The formulation of the problem in this study is how to apply infiltration wells to control rainwater puddles in residential areas.The working principle of an infiltration well is to distribute and collect rainwater into a hole or well, where the rainwater on the ground will then slowly seep into the ground. Below the ground, this seeping water will seep into the soil layer called the unsaturated layer, where this layer can still absorb water. Thus, the entry of rainwater into the ground will increase groundwater. The application of infiltration wells in residential areas requires calculation of the area covered by buildings and watertight. The number of infiltration well areas that need to be made is 4% of the watertight area.]]>
