A system for the transportation and storage of a product comprising a tank including a cylindrical wall section and two ends which define a cylindrical tank periphery, wherein the tank periphery has an interior and an exterior; a recessed valve box including one or more side walls, a bottom wall, and a removable, sealable top cover which can be attached to the one or more side walls to seal the valve box, wherein the valve box side walls are sealably joined to the cylindrical wall section such that the valve box extends through the cylindrical wall section into the interior of the tank periphery and is partially or totally disposed in the interior of the tank periphery; and one or more valves disposed in the valve box. Each valve has a first and a second end, wherein each first end may be connected to a pipe which passes through a wall of the valve box for introducing product into the tank or withdrawing product from the tank, wherein the valves are disposed partially or totally within the tank periphery, and wherein the tank has a rigid framework surrounding the tank and valve box, wherein the framework is attached to and supports the tank, and wherein the framework defines a periphery which encloses the periphery of the tank. The product in the tank can be isolated from the atmosphere surrounding the tank when the valves are closed.
