The cylindrical water supply tank is used to supply drinking water in the event of a natural disaster. This tank normally functions as a part of the water supply system and is located on the water supply pipe under the house. We investigated the effects of the unsteady flow rate and the temperature of the inlet water on the displacement efficiency of old water in the tank with an access hole. The experiment was carried out using a half-scale model of the tank. The replacement efficiency of old water with new water in the tank depends on the temperature of the inlet water. If the temperature of influent new water is lower than that of the old water in the tank, the displacement efficiency decreases due to the dead water in the access hole. It was confirmed that the difference in displacement efficiency between the steady and intermittent flow rates is small.
