An improvement to a collapsible liquid holding tank includes a chute which extends outwardly from an opening in one of the tank side walls. The chute is formed by a bottom panel and side walls of collapsible material, the bottom panel perimeter being reinforced by a hinged frame which swings between "vertical" and "horizontal" conditions in which the opening is "closed" and "opened," respectively. A clamp hinged on the top rail of the tank secures the chute in the "closed" condition in which the bottom panel of the chute extends across the opening. To drain the tank, the clamp is rotated clear of the frame and the chute is swung to the "opened" condition by the weight of the liquid in the tank.
