A water storage tank (10) has exterior walls (12, 14, 16) and an interior space defining a storage volume. The tank has passageways (30, 32, 34, 36) extending from an upper part of the tank to a lower part of the tank. The passageways have an opening at an upper end thereof such that a reinforcing or strengthening material, particularly concrete, can be inserted into the one or more passageways to strengthen the tank. The tank can be installed underground or even under driveways. The tank is also suitable as a transport tank because the passageways act as baffles.
