Abstract
A portable water tank comprises a foldable receptacle having a bottom wall and vertical sidewalls; a frame to support the sidewalls in an upright position, the frame including upper and lower rails, and vertical posts joining the upper rail to the lower rail. The receptacle includes a drain sleeve disposed near the bottom wall and extends between corresponding portions of the upper and lower rails, and between a pair of the posts. The sleeve overlies the corresponding portion of the lower rail. Reinforcement members are attached to the corresponding portions of the lower rail and the pair of posts. A valve is operably attached to the pair of posts and the corresponding portion of the lower rail. The valve is operably associated with the drain sleeve and has an open position to allow water within the receptacle to flow through the drain sleeve, and a closed position to keep water from flowing through the drain sleeve.
