The water supply system has been designing by decision process such as use place of water, calculation of water supply amount, capacity of water tanks and pumps, pipe size. Especially, when we estimate water supply amount excessively, the initial cost and running cost will increase according to enlargement of the water tank and pump capacity, and water quality of ground water tank can become worse. Therefore, calculation of water supply amount is basically
most important factor at water supply system design. In order to calculate exactly water supply amount, we should set up basic data such as daily water supply amount, daily using time, persons per effective area etc.. This research would estimate the calculation data of water supply amounts by a day and a person through survey and analysis of monthly water consumption at elementary school buildings in Ulsan city, and suggest basic data for the water supply system design.
