PURPOSE: An underground water filling and heat island effect reduction drain is provided to positively influence vegetation growth by filling with underground water and soil moisture through the filtering of contaminants in the initial rain and soil absorption of precipitation, and to reduce a heat island effect by evaporation heat. CONSTITUTION: An underground water filling and heat island effect reduction drain comprises a side wall(110), an inner side wall(140), a first permeation panel(150), a second permeation panel(151), and a first filling material. The side wall is installed at both sides of the open upper surface, and the inner side wall is installed at the lower inner side of the side wall. The first permeation panel is installed in between the side wall and an upper side of the inner side wall, and comprises multiple first permeation holes. The second permeation panel is installed at the lower side of the first permeation panel, and comprises multiple second permeation holes. The first filling material is filled between the first permeation panel and the second permeation panel.
