The impact of land use change in developing areas, especially at Passo Village, Ambon Bay, is a serious problem if continuously ignored, and then RT (neighborhood) number 21.22 and 23 will experience inundation throughout the rainy season. This is because sea levels are higher than residential areas. In order not to experience a long puddle, the solution is to make a water catchment well by considering the condition of the existing drainage system that is no longer able to be burdened. From the results of the hydrological analysis in a residential area of 12.71 Ha, an average runoff coefficient of 0.85 was found with a rainfall intensity of 72.83 mm / hour. From the results of the discharge analysis for the return period of 2 years is 2.17 m3 / sec. Permeability for infiltration wells on site is 0.847 m / day, the calculation of the need for infiltration wells installed at the study site is based on the analysis of the width of the building roofs for types 36, 45, 50, 60.70 and 120. Construction of water infiltration wells made using two types of aggregates rough for non-sand concrete (non-structural concrete) with a mixture of 1 cement and 6 rocks or broken stone. Water infiltration wells installed from the calculation results for material from coral are 663 pieces and from 670 broken stones, individual infiltration wells are made in a circle with a sinking diameter of 1.25 meters and a depth of 2 meters, thus found reduced surface flow efficiency that can be reduced type 36 is 12.69% type 45 is 9.9%, type 50 is 8.82%, type 60 is 7.25%, type 70 is 6.15% and type 120 is 3.50% of infiltration wells made of rock.
