PURPOSE: A drain board is provided to collect water into a predetermined water tank by forming vertical parts on both ends to prevent water from flowing out through both ends. CONSTITUTION: A drain board comprises a board main body(110) equipped with a plurality of protrusions(112), a vertical part(120), and a filter bag. The vertical part prevents water drained through a gap between protrusions from flowing out through both ends of the board main body and allows water to be collected into a predetermined water tank. The filter bag covers the vertical part and the board main body and allows the water permeated through the ground to flow in the upper part of the board main body. |
