N-43856 | Norwesco’s 400 gallon freestanding water tanks are ideal for when you need to store or transport water, but need a tank that will fit through a conventional door. Because these tanks are designed to fit through a conventional doorway, they are best suited for residential and commercial applications. These freestanding water tanks do not need any steel support frame and are supported just fine as is. The polyethylene resin is both UV stabilized and FDA approved so that you can store water more safely and more effectively. These tanks are made through a rotational molding process and turn out as a one-piece unit. The 16-inch vented twist entry provides a generous amount of room to fill the tanks without spilling.
