The Chem-Tainer 500 Gallon Plastic Vertical Liquid Storage Tank (SKU TC4876IA) is a 76-inch-tall white polyethylene vertical tank that holds 500 gallons on a square 48 x 48 inch footprint. It is built for liquid storage where you need real capacity without a wide footprint, and the heavy 1.9 specific gravity rating gives you room above plain water for denser contents. If you are cross-shopping a 500 gallon vertical storage tank, this is the natural-white, 76-inch-tall version of that size, and the part number is how you confirm you are quoting this exact unit rather than an alternate-height 500.
Will it work for your liquid?
The tank stands 76 inches tall on a 48 x 48 inch base and rates to a 1.9 specific gravity, which means the polyethylene wall is built for liquids substantially heavier than water. Filled with water alone the contents weigh about 4,170 pounds; at its full 1.9 SG rating the tank is engineered to carry up to roughly 7,923 pounds of liquid. That is about 3,753 pounds of headroom above plain water, which is the practical reason to choose this rating over a lighter-built vertical tank if your contents are denser than water. Use those numbers when you spec the pad and base support: a vertical tank this tall needs a level, fully supported foundation under the entire 48 x 48 inch footprint, not just the perimeter. If you are unsure whether 500 gallons is the right size for your draw-down and refill cycle, run your numbers through the Tank Sizing Calculator and read the Tank Sizing Guide before you commit.
Sizing and comparison
This SKU is the 76-inch-tall variant of the 48-inch-diameter 500. Chem-Tainer builds the same diameter in alternate heights, so for a deeper look at how the white vertical tank compares across those configurations, see the 500 Gallon Vertical Liquid Storage Tank buyer's guide (48 x 68) and the 48 x 73 buyer's guide — those cover same-diameter 500s at different heights, so the height difference is expected, not a typo. If you are weighing brands at a larger size, our Snyder vs Norwesco vs Chem-Tainer vertical tank comparison walks through the differences. For larger emergency-water and reserve applications, the fire-water reservoir design guide covers sizing discipline and freeze protection for cold-climate sites.
The mistake to avoid
Two things trip people up on a tall vertical tank like this. First, this listing carries no published fitting schedule, so confirm your fitting plan before delivery: verify the bulkhead, outlet, and fill arrangement you need against the technical drawing on this page, and call us at 866-418-1777 to lock those in before you order rather than assuming a configuration. Second, do not under-build the base. The 1.9 SG rating only holds up if the full 48 x 48 inch footprint sits on a continuous, level, load-rated pad; an unsupported edge or an uneven surface is the most common cause of stress on a vertical tank's lower wall.
This 500 gallon vertical tank ships LTL freight from the Chem-Tainer plant in Lake Wales, FL, with freight quoted live to your ZIP. Because it ships from that single Florida origin, buyers outside the Southeast should pull a live ZIP quote with the Freight Cost Estimator before comparing total cost, since LTL from one plant drives the delivered-cost difference against the list price. Get an exact number that way, or call us at 866-418-1777 and we will quote the run and confirm fittings before your tank ships. Listed price is the tank only and does not include LTL freight.
