The rain water is an important source to feed to the groundwater aquifer, whether directly or by harvesting and recharging. The importance of purification is to reduce the risk of pollutants from runoff rainwater. The use of sand filter as a technique which is not expensive and commonly for removing contaminants from the water and wastewater treatment industries. In this research, the selected methodology used is laboratory testing, by manufacturing plant to experimented the appropriate sand filter for purification and made simulation for the infiltration of storm water through sand filter depth of 2 meters, in order to find the relationship between the depth-of-hand, and the removal of suspended solids and fecal coliforms bacteria on the other hand, to knowledge the effective depth influential that gets the purification. The research results during three days of infiltration show that the sand filter can provide purified water with a concentration of suspended solids less than 20 mg / liter at a depth of 75 cm and completely removes fecal coliform bacteria at a depth of 150 cm. Finally, the research tested the increased concentration of suspended solids or fecal coliforms and found that no significant impact of that on the purification and the percentage of removal, but it is expected increase the occurrence of clogging in the filter.
