The design of rainwater storage system unit to manufacture its reservoir tank was tried, the simulation to predict of their structural strength was carried out. Rainwater storage system unit should be easy to their machinability, transport and assemble. Especially, their structure was able to secure the water storage space, withstand loads and easily response to pollution. Considering these various requirements, they have to Doria-pillar structure of the Roman architectural style because these designs could disperse the loads which are applied to them. Therefore, the six kinds of models possible were proposed. Several boundary conditions were given to each model. Their structural strength was predicted through the simulation on their stress and the displacement distribution to constant load. From the evaluated data, the structure which has a large pillar in the central of unit and four small pillars each corner was the best.
