The inlet pipe 410 may sequentially include a portion parallel to the ground (a portion horizontal to the ground), a portion perpendicular to the ground, and a portion U bent in a U shape. The portion perpendicular to the ground is formed to extend from the top to the bottom of the water treatment tank 400 . The U-shaped bent portion U is connected to the end of the vertical portion. Accordingly, the water may descend along the vertical portion, then make a U-turn at the U-shaped curved portion (U) and rise.

After passing through a parallel part (horizontal part), a vertical part, and a curved part (U-shaped (U)) sequentially, the rainwater flows directly into the first filtering unit 420 or is collected in a separate water tank. It may flow into the first filtering unit 420 .

Rainwater that has passed through the second filtering unit 430 may be moved to the storage tank 100 and stored therein. When rainwater that has passed through the water treatment tank 400 moves to the storage tank 100, it does not pass through a separate transfer pipe, but falls by gravity and can be collected in the storage tank 100. Here, the water treatment tank 400 may be coupled to the upper side of the storage tank 100.

Depending on the level of the water W in the storage tank 100, constant water may be further supplied or the water W may be discharged to the outside.
