Abstract



Environmental damage which leads to the deterioration of groundwater supply potential is caused by changes in land use especially in the area of groundwater recharge. The aim of this present study is to create a model of the mapping of the local housing distribution which is suitable as rainwater catchment system as groundwater recharge. Spatial approach method was used in this study. The measurement of the soil permeability coefficient, soil layer structure, the surface depth of the groundwater with the number of locations as many as 88 residential areas were conducted as measurements in this study. The results of this study in 88 residential areas within 16 districts located in Semarang showed that 30 locations are eligible for the establishment of vertical groundwater catchment system with infiltration wells and 3 locations are eligible for the establishment of horizontal catchment system with infiltration trenches.
