The 6500 Gallon Vertical Liquid Storage Tank from Norwesco stands 150 inches tall on a 119-inch diameter footprint, holding 6,500 gallons of water or other liquid in natural white polyethylene. If you are sizing a vertical storage tank for bulk water, irrigation supply, fire reserve, or process holding, the question is whether the pad, the contents, and the freight all work for your site. The pack data answers all three.
Will it work for your site?
This is a 6,500-gallon vertical tank measuring 119 inches in diameter and 150 inches tall, so plan a level, fully supported pad with overhead clearance for the full height plus your fill plumbing. The 119-inch diameter is a circular footprint, so whether you pour round or square, the base must fully support a 119-inch circle. Filled with plain water, the tank and contents reach 54,210 pounds, so the pad must carry that load across the entire footprint, not just the perimeter. The polyethylene is rated to a specific gravity of 1.5, and at that rating the structure is engineered to hold up to 81,315 pounds of contents. That means even at the full 6,500-gallon fill you have weight headroom for liquids heavier than water, up to 1.5 SG, provided chemical compatibility checks out. Use that 1.5 SG figure as your ceiling and confirm your liquid sits at or below it before committing. If you are comparing this to a different footprint, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to the space you have.
How it ships
A tank this size ships LTL freight, quoted live to your ZIP code. Norwesco produces this vertical tank at two plants, Hanford, California and St. Bonifacius, Minnesota, so freight runs from whichever location is nearest you. Because it ships from both coasts of the country, your freight cost depends heavily on which plant is closer, so run your ZIP through the Freight Cost Estimator to see the routed quote before you commit, or tell us your delivery ZIP and we will route from the nearer plant. A 6,500-gallon vertical tank is an oversized load, so confirm site access for the delivery truck and have equipment ready to offload, since LTL carriers deliver curbside.
Fittings and the mistake to avoid
Fitting configuration, including bulkhead and manway sizes, count, and gasket material, is confirmed at quote rather than fixed on this listing. Call 866-418-1777 to spec inlets, outlets, and gaskets for your install, and to verify gasket chemical compatibility with your liquid. The most common error on a tank this large is treating the 1.5 specific gravity rating as a green light for any liquid. The rating tells you the structure can carry weight up to 1.5 SG, but it says nothing about chemical compatibility between your liquid and the polyethylene wall or its fittings. For plain water and water-based storage this tank is a straightforward fit; for anything else, verify both the specific gravity and the chemical compatibility first. The second mistake is underbuilding the pad: at 54,210 pounds full of water alone, an uneven or undersized base will stress the tank wall and void the structural rating. Confirm overall dimensions and your site plan before you set the pad and plumbing.
