This has experienced inundation since 2018. study aims evaluate existing drainage systems, assess performance of channels in serving surface runoff their catchment areas and provide alternative solutions by eco approach using rainwater harvesting recharge well. was carried out processing daily rainfall data over time span 2011 2021. Hydrology analysis performed manually, hydraulic simulation conducted Storm Water Management Model (SWMM) 5.1. The intensity applied for modeling 37.29 mm/hour, 46.96 53.41 mm/hour 2, 5, 10 years return periods, respectively. results system show that there are 2 (two) experience overflow during 5-year periods increase 5 (five) 10-year periods.
