The Norwesco 500 Gallon Vertical Liquid Storage Tank stands 68 inches tall on a 48-inch diameter footprint, holding 500 gallons of water or other liquids in a single upright cylinder of UV-stabilized polyethylene. Cast in natural white, the translucent wall lets you read the liquid level at a glance without opening the lid. This is a workhorse vertical storage tank for water storage, rainwater collection, well-water buffering, and general liquid handling where a compact 48-inch base needs to do the work of a larger footprint.
Will it work for your job?
The numbers tell you how this 500 gallon tank behaves once it's full. Filled with water it carries about 4,170 pounds of contents - that's the load at a specific gravity of 1.0. Norwesco rates the wall to a 1.9 specific gravity, which raises the absolute ceiling to roughly 7,923 pounds of contents at maximum rated density. If you're storing something heavier than water, do the math before you order: gallons x 8.34 x your liquid's specific gravity, and keep the result under 7,923 pounds. That heavy SG rating is the reason buyers reach for this Norwesco vertical tank over a thinner-walled water-only model - it gives you real headroom for denser liquids, not just a higher number on a spec sheet. The 48-inch diameter and 68-inch height keep the unit narrow while still reaching 500 gallons, so it tucks against a wall without sprawling across your pad. For a side-by-side of capacity, height, and footprint against neighboring sizes, the Tank Sizing Calculator and Tank Sizing Guide walk you through matching gallons to the space you have.
How it ships
This vertical storage tank ships LTL freight from the nearest Norwesco plant to your delivery ZIP. For this model that named origin is Fairfield, TX; the line is also molded in Mississippi, so Gulf and South-Central buyers usually see the shortest lanes and the lowest freight. Because a 48-inch-wide tank rides upright on a pallet and can't be parcel-shipped, freight is quoted live per ZIP rather than baked into the list price. Run your ZIP through the Freight Cost Estimator for a real number before you order, or call 866-418-1777 and we'll quote it with you.
The mistake to avoid
The trap on a vertical storage tank this size is treating the diameter and height as a stand-alone spec and skipping the foundation. A full 500-gallon tank puts about 4,170 pounds onto a 48-inch circle - roughly 1,810 square inches of bearing area, or about 2.3 psi when full of water - and that load climbs fast with a denser liquid. Set the tank on a smooth, continuous, level pad that fully supports the entire base; never bridge it across gaps, blocks, or uneven gravel, which concentrates stress on the lower wall. Outlet height and bulkhead location are fixed by the mold, so confirm placement against the technical drawing on this page before you plumb anything. And if you're storing something heavier than water, the 1.9 SG rating is your ceiling - stay under it.
