A fluid reservoir includes a housing shell defining a cavity, and a flexible, resilient water impervious bag-shaped liner mounted in the cavity so as to substantially fill the cavity when the liner is filled with fluid. The liner is formed from a flexible water- imperious sheet by forming the sheet into a cylinder, then forming a water-tight first seam along a bottom edge of the cylinder, then folding outer corners of the first seam over, so as to overlap a center portion of the first seam, and so that bottom edges of the outer corners, once so folded over, register substantially co-linearly within a bottom edge of the center portion of the first seam. An upper portion of the liner is thereby urged to bag open. The upper portion thus forms a substantially frustoconical shape. The upper portion is contiguous with a lower portion of the liner. The lower is portion substantially wedge shaped. The bottom corners overlapping the center portion of the first seam are sealed onto the first seam so as to form a second seal.
