Abstract

The rapid expansion of the Nuansa Alam Cilebut Asri Housing Area has transformed 6 hectares of agricultural land into residential areas, resulting in the loss of natural infiltration zones due to increased impervious surfaces from roads and buildings. This land-use change has altered the hydrological characteristics of the area by increasing surface runoff, intensifying inundation risks during extreme rainfall events, and reducing groundwater recharge capacity. This study evaluates water conservation measures to mitigate inundation impacts through the implementation of infiltration wells. A quantitative approach was applied by integrating soil permeability testing, frequency analysis of 10-year historical rainfall data from three observation stations, and assessment of suitable water conservation structures. The Log Pearson Type III distribution was selected based on the goodness-of-fit test for a 2-year return period, producing a design rainfall of 109.107 mm/day and a design runoff discharge of 0.284 m³/s. The analysis indicates that the runoff can be effectively controlled through the construction of 360 infiltration wells with a diameter of 1 m, a depth of 3 m, a storage capacity of 2.36 m³, and a filling duration of 2 hours and 20 minutes. The proposed green infrastructure approach significantly reduces surface runoff and enhances the hydrological resilience of the area through sustainable groundwater recharge.
