Abstract


Soil water conservation with how water infiltration through recharge wells is very important considering the land use changes in the earth's surface as a consequence of the growth in population and economy, society, decrease the rate of erosion runoff will decline. If the surface flow decreased, soils eroded and drift would be reduced. The impact of rainwater runoff and erosion too small to be small. This research was conducted in June to August 2016 in West Pasaman PTPN VI. This study aims to determine the number of recharge wells, dimensions, distribution of recharge wells and reduce the volume of runoff that occurs. This research was conducted through the following steps: (1) Analysis of Intensity Rain, (2) Determination of the coefficient of runoff, (3) Analysis of Spatial Hydrology, (4) Calculation of Volume runoff, (5) Calculation of recharge wells needs, and (6) Distribution recharge wells, The secondary data used is the rainfall data, Map Afdeling PTPN VI, and the SRTM data were used to analyze the volume of runoff. The results of the analysis are obtained on Cambodgien 1 there were 21 water catchment areas with runoff volume, and the number of wells required catchment different. So from 21 the catchment area takes 5200 recharge wells that can hold the runoff volume of 23,400 m3 with areal extents section, 948.985 Ha, infiltration wells have dimension 1.5m x 1.5m and height 2m
