The Norwesco 500 Gallon HD Vertical Storage Tank (SKU 45877) is a heavy-duty 500-gallon vertical tank molded in natural white polyethylene, standing 68 inches tall on a square 48 x 48 inch footprint. The "HD" matters here: this tank carries a 1.9 specific gravity rating, and that number is the one to check first. It does not add capacity - it certifies that the tank wall is built to hold a liquid up to 1.9 specific gravity at full volume. For a vertical storage tank in this size class, confirming the SG rating against what you actually intend to store is the difference between a tank that lasts and one you overwork from day one.
Does it work for your job?
Filled with plain water, this tank holds roughly 4,170 pounds of contents at 500 gallons. The 1.9 SG rating means the wall is engineered to carry contents up to 7,923 pounds at full volume - that is the heaviest liquid (1.9 specific gravity at 500 gallons) the tank is built to support, not bonus capacity above 500 gallons. The 48 x 48 inch footprint keeps the pad and tie-down layout square and predictable. If you are not certain 500 gallons matches your draw-down or storage cycle, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide before you commit. Fitting and outlet configuration is not listed in this record, so confirm the exact ports you need before ordering by calling 866-418-1777.
Where it ships from and how freight works
This Norwesco vertical storage tank is stocked in Mississippi and Texas; freight is quoted from the fulfilling location, the Fairfield, TX plant. It moves LTL (less-than-truckload), and freight is quoted live to your ZIP rather than baked into the listed price. Get an exact number for your delivery address with the Freight Cost Estimator, or call 866-418-1777 and we will quote it for you. The square 48-inch footprint and 68-inch height keep this tank inside standard LTL handling, but always confirm whether you need liftgate or limited-access delivery when you request the quote.
The mistake to avoid
The most common error on a vertical storage tank like this is treating the specific gravity rating as a suggestion. The 1.9 SG figure defines the maximum density the wall is built to support; storing a liquid denser than rated overworks the wall and shortens tank life. If you are planning anything heavier than water, verify the product's specific gravity against this tank's 1.9 rating first. The second mistake is underbuilding the pad. At 1.9 SG the base must carry up to 7,923 pounds of contents plus the tank's own dead weight, all bearing across the 16-square-foot (48 x 48 inch) footprint - that combined load is the figure that drives your pad spec. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that base right.
Whether you are setting up bulk water storage, a fire-water reservoir, or a rural draw-down supply, this 500 gallon vertical storage tank gives you a square-footprint, high-density-rated vessel that ships LTL. For design context on remote-site reservoirs, see our guide to fire-water reservoir tank design for rural and remote sites.
