To recover the underground water level by effectively using rain water falling down on the ground, purifying it to lead into an aquifer such as gravel layer in the ground.
A water conveyance equipment for underground water storage is equipped with a steel pipe pile 11 driven into the ground from the earth to execute, provided with the lower end reaching the underground aquifer to open and provided with the upper end opened in the vicinity of the ground surface to use it as a rain water intake 11a covered with a water permeable material 13 and a filter 12 installed to the inside of the steel pipe pile 11 and led to the underground aquifer 6 after water flowing down from the rain water intake 11a in the upper end is filtered. After the water flowing down from the rain water intake 11a opened in the vicinity of the ground surface to the inside of the steel pipe pile 11 is purified through the filter 12, it is led to the underground aquifer 6 to store in the ground. By the constitution, the recovery of the ground water level is promoted. In the case of a disaster, ground water is pumped up by means of a pipe installed in the steel pipe pile 11 to ensure drinking water.
