Continuous and excessive use of groundwater causes a decrease in the water table, as well as drought during the dry season. Land use change causes reduced water infiltration, leading to flooding and inundation during the rainy season. This happened in KayuBesi Village, which is located in PudingBesar District, Bangka Regency. The purpose of this planning is to determine the dimensions of the rain water harvesting pool integrated with infiltration wells in the village office as the center of the village government and the mosque as the center of worship. The method used to calculate the volume of rainwater collected in a rain water harvesting pond is the result of substitution and modification made by Maryono from the relationship between discharge, volume of rainwater, and duration of rain with the relationship between discharge, speed of rainwater, and the cross-sectional area of the gutter pipe. The method used to calculate the depth of the infiltration well is the Sunjoto method. The results of the planning for the KayuBesi Village Office obtained the dimensions of the rain water harvesting pool with a pool length of 5 m, a pool width of 4 m and a pool height of 1.5 m, as well as an infiltration well with a diameter of 1 m and a depth of 2.5 m, while for the KayuBesi Village Mosque obtained the dimensions of the rain water harvesting pond with a pool length of 6 m, a pool width of 5.5 m, and a pool height of 1.6 m, as well as an infiltration well with a diameter of 1 m and a depth of 4.5 m.
