Each tank includes a generally hollow body portion and a supporting portion integral with the body portion. The supporting portion includes a base and a tip-over-preventing portion for preventing the tank from tipping over when the tank is tilted laterally about the base. The supporting portion also includes grooves extending therein which flexible hoisting lines can be securely received for allowing the tanks to be transported. The supporting portion is also designed to accommodate the fork of a forklift. The tanks are also stackable and are nested via ribs projecting from the top portion of tanks and grooves defined at the underside of the tanks.
