Clean Water availability is a serious problem in Indonesia. A lot of water has been treated by coagulation and flocculation process. It might be the rate of high water rates and not all citizen can being it. So researcher tried to analyze how to make pre treatment to reduce contaminant, such as TSS, used soil purification method so could reduce coagulant, TSS and total coli close to drinking water standards. The technology of soil purification method is Infiltration gallery. Infiltration gallery is method that replicate soil mechanism absorption or filtration in daily process. This research tried to find the optimal soil composition used as an approach to dynamic system modelling. System dynamic modelling was used to input all of variable that influence soil filtration procces such as weather, conductivity hydraulic, TSS influent, percentage soil removal to TSS, capacity water, evaporation and catchment area. All variables could be changed until got TSS close to zero. It could be one of policy to the government to making decision in reducing production cost, if used infiltration gallery as pre treatment in IPAM and could save coagulant consumption the result is sand loamy could reduce 63.50% of TSS with conductivity 0.000217 and sand loamy have composition 85% sand and 15% clay.
