An intermediate water-saving closestool water tank. A basin drain pipe is connected to the closestool water tank. Before the closestool is used, a time-delay valve (13) or a ping-pong valve is pressed so that tap water is supplemented when the water supply tank of the basin is not full. After the tap water is supplemented in the water tank and before the closestool is flushed, the ping-pong valve needs to be pressed again to prevent a ball float type water supplementary valve (14) from automatically supplementing tap water subsequently. The time-delay valve (13) does not need to be pressed again, and a flushing valve (17) is pressed normally when the closestool is flushed. Two flap valves are arranged at the bottom of the basin, one of the flap valves is directly connected to the drainage sewer, and the other one is communicated with the closestool water tank. The device achieves energy-saving and water-saving purposes.
