The Norwesco 6500 Gallon Vertical Liquid Storage Tank stands 147 inches tall on a 120-inch diameter footprint, holding 6,500 gallons of water or other liquids in a polyethylene body. It carries a 1.5 specific gravity rating, meaning the wall is engineered to hold contents up to 1.5 times the weight of water - a full water load weighs 54,210 pounds, while the structural ceiling is 81,315 pounds of contents. That headroom is why municipal, agricultural, fire-reserve, and bulk water operations reach for this size of Norwesco vertical storage tank.
Will it work for your site
Size the pad and the application before you buy. Full of water this tank weighs 54,210 pounds, and the slab or compacted base under the 120-inch diameter footprint has to carry that load evenly across the full circle - no point loading, no soft spots. The 1.5 SG rating gives you a usable weight band: water (SG 1.0) is 54,210 pounds, and the wall is rated to 81,315 pounds, so any liquid up to 1.5 times the weight of water is within rating. Check the specific gravity of your intended contents against that 1.5 number before you commit. If you are sizing for your usage and refill cycle, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide. Need more capacity on the same 120-inch footprint? The 8400-gallon vertical tank stands taller on the identical diameter.
Fittings and plumbing
Outlet, bulkhead, and gasket sizing are not published for this tank, so confirm them against the technical drawing on this page or by phone before you plumb anything. Plan fitting and outlet placement up front - plumbing a 147-inch-tall tank after it is set is far harder than planning it before the truck arrives. Do not assume a specific fitting size or gasket material is included; verify on the drawing first.
Freight: how a 6500-gallon tank ships
A tank this size moves by LTL freight, quoted live to your ZIP code. We ship the 6500 gallon vertical tank from whichever Norwesco plant is closest to you - Albertville, Alabama or Fairfield, Texas - and your ZIP determines which one quotes, so running the Freight Cost Estimator shows you the lower-haul option. Get your exact number there, or call 866-418-1777 and we will quote it for you. Because of the 120-inch diameter and 147-inch height, confirm your delivery site can receive and offload an oversized tank before the truck arrives.
The mistake to avoid
The most common error on a tank this large is underbuilding the foundation. The 1.5 SG rating describes the tank's structural capacity, not your pad's - a base that handles a smaller tank will not carry 54,210 pounds of water spread over a 120-inch circle, and if you are storing a heavier-than-water liquid you should build toward the 81,315-pound rated ceiling. Pour or compact the foundation to the full rated load before delivery. The second mistake is assuming the natural white color makes this a potable-only tank; it is a general-purpose vertical liquid storage tank, so match it to your specific contents and confirm compatibility for anything other than water.
