Each tank is 84 inches long 60 inches wide and 69 inches high. Four in total and there's also a cofferdam for spill containment that's
approximately 20 inches tall around the whole perimeter of four tanks. It's quarter inch or maybe 3/8. Definitely would be a good salvage for someone with the right tools and needs.
The steel on the cofferdam maybe 3/16 not 3/8
