ABSTRACT:
A dual compartment liquid storage tank has a bottom wall, an annular side wall extending upwardly from the bottom wall and a top cover, to define an interior space. A bulkhead extends across the interior space to divide it into two separate compartments completely isolated from one another. The bulkhead is arcuately curved about a vertical axis and is marginally sealed to the bottom and side walls and top cover to prevent transmission of liquid from one compartment to the other. The curved configuration of the bulkhead withstands pressure differentials due to unequally filled compartments without buckling or distortion or failure of the seals, more effectively than a flat bulkhead.
