The Chem-Tainer 500 Gallon Plastic Vertical Liquid Storage Tank (SKU TC6446IC) is a 500 gallon vertical storage tank molded in polyethylene with a 1.5 specific gravity rating. It stands 46 inches tall on a 64 x 64 inch footprint, giving you a low, wide, stable profile that handles full water loads without towering over a pump shed or a low-clearance space. If you are weighing a 500 gallon vertical tank for water, this is one of the more grounded options in the size class.
Will it work for your job?
This tank carries a 500 gallon working capacity in a vertical body measured at 46" H on a 64 x 64 inch footprint. The polyethylene shell is rated to a 1.5 specific gravity, meaning it is built to hold contents up to 1.5 times the weight of water. For straight water service the math is comfortable: full of water the tank weighs roughly 4,170 lb, and the wall is rated to carry contents up to about 6,255 lb. That headroom is why the same body shows up under both water and denser-liquid duty. Pour the slab and plan supports for the full 4,170 lb water weight, and confirm the fill, outlet, and lid layout against the technical drawing on this page before you set it and order plumbing. If you are not certain 500 gallons matches your draw and refill cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide first.
How it ships
A 500 gallon vertical tank ships LTL freight on a pallet, not by parcel. This one ships from the Marked Tree, AR plant, and freight is quoted live to your ZIP rather than baked into the list price. Use the Freight Cost Estimator to get a freight quote to your address, or call us at 866-418-1777 and we will quote it for you. Have a forklift, loading dock, or a few hands ready at delivery, since an empty tank this size is awkward to handle off the truck.
The mistake to avoid
The trap on a multi-purpose vertical like this is treating the 1.5 specific gravity rating as a green light to store anything. It is not. That rating describes the structural weight the wall can carry, not chemical resistance. For plain water and similar light liquids you are well inside the envelope. Before you put anything heavier or chemically active into it, confirm the contents against the manufacturer's resin and SG guidance. The other common miss is the pad: at 64 x 64 inches this tank needs a genuinely flat, fully supported base, since an unsupported edge concentrates load and works against the very wall strength the 1.5 rating gives you. Check whether your 64-inch footprint is round or square against the technical drawing before you form and pour, because that changes how you size the slab.
