For an efficiency improvement in old apartment houses, there is a possibility that remodeling is easier to gather similar efficiency with less money than new construction. Generally, the water supply system in a apartment house uses the gravity water supply system or booster pump system. In this study, in order to compare which system is more efficient, the present
worth analysis method was used. We could get the result that the booster pump system is 10% cheaper than the gravity water supply system, consequently it is more economically efficient than past systems.
