The Chem-Tainer 500 Gallon Vertical Liquid Storage Tank is a white polyethylene vertical tank rated to a 1.9 specific gravity, holding 500 gallons on a compact 63 x 63-inch footprint and standing 53 inches tall. Full of water it weighs about 4,170 lbs; the structure itself is rated to a maximum contents weight of 7,923 lbs. That 1.9 rating is the selling point on this build: it means the tank walls carry liquids up to 1.9 times the density of water, well past the 1.5 specific gravity common on entry-level vertical tanks, so it handles denser solutions without flexing where lighter-rated tanks struggle.
Will this 500 gallon tank work for your liquid?
This is a vertical storage tank, and the question that decides the order is how heavy your liquid is. For plain water service the loaded tank runs roughly 4,170 lbs; the 7,923 lb rated-contents figure is the headroom that lets it safely store liquids heavier than water. Confirm your specific gravity against the 1.9 rating before you commit. To check that 500 gallons matches your draw-down and refill cycle, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide. Fitting and gasket configuration on this tank is confirmed at the time of order, so call 866-418-1777 with your inlet, outlet, and vent requirements and we will line them up to your plumbing and to the liquid you are storing rather than leave it to guesswork.
Dimensions and the loaded-weight mistake to avoid
The tank stands 53 inches tall on a 63 x 63-inch outside footprint. Review the technical drawing on this page for the exact dimensional callouts before you finalize your plumbing and tie-down plan. The single most common mistake on a tank this size is sizing the pad for water and forgetting the rated load. Build the foundation and any straps or restraints for up to 7,923 lbs of loaded contents (about 4,170 lbs if you only ever store water) spread across the 63 x 63-inch base, on a level, fully supported concrete or compacted pad. A vertical tank of this height needs that base flat and continuous, not just strong at the edges.
Common uses and sizing references
A 500 gallon vertical tank is a workhorse for rural water supply, irrigation, bulk liquid storage, and reserve capacity. For sites using it as a fire-water reservoir, our fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. If you are weighing this 500 gallon vertical storage tank against other builds, note that the 48 x 68 and 48 x 73 variants in our 500-gallon buyer's guides are taller and narrower than this 63 x 63 x 53 squat profile, so confirm the geometry that fits your site before comparing; our brand comparison guide walks through how Chem-Tainer stacks up against Snyder and Norwesco.
This tank ships LTL freight from Hummelstown, PA, with freight quoted live to your ZIP. Freight scales with distance from Pennsylvania, so a Northeast or Mid-Atlantic site will quote low while a long western haul on a 53-inch rigid tank costs more. Get your exact number with our Freight Cost Estimator or call 866-418-1777. Because it is a tall, rigid vertical tank, plan for liftgate or forklift access at delivery and have the level pad prepared before the truck arrives.
