The Norwesco 250 Gallon Vertical Liquid Storage Tank stands 89 inches tall on a 30-inch diameter footprint, which makes it the right call when you have vertical room to spare but a tight floor plan. It is molded from polyethylene in natural white and carries a 1.5 specific gravity rating, the top of Norwesco's standard SG ladder. Where many vertical storage tanks are rated at 1.0, 1.1, or 1.35, this 1.5 rating is a feature you are paying for: it tells you exactly how dense a liquid this tank is built to hold.
Will it work for your install
Run the numbers before you commit the space. Filled with plain water this Norwesco vertical tank carries about 2,085 pounds, and at its full 1.5 specific gravity rating it is engineered to hold up to 3,128 pounds of contents. That gap matters: the tank wall can handle a liquid heavier than water, but your pad, your stand, and your floor have to carry the loaded weight. Spread over the 30-inch diameter footprint, a fully loaded tank puts roughly 637 pounds per square foot on the base, so size your slab or stand accordingly and support the entire bottom, not just the perimeter. Use the Tank Sizing Calculator to confirm 250 gallons fits your draw-down and refill cycle, and the Tank Sizing Guide if you are weighing this against a wider, shorter vertical tank.
Read the specific gravity before you fill it
The single most common mistake with a vertical storage tank like this one is matching the wrong liquid to the specific gravity rating. The 1.5 SG rating is the ceiling, not a suggestion. Plain water sits at roughly 1.0, so water and most water-based liquids sit comfortably within range. If you are storing anything denser, verify its specific gravity stays at or below 1.5 before you fill, and never overfill beyond the rated content weight, because that is what stresses the wall over time. When in doubt, call us at 866-418-1777 and we will walk through your liquid with you.
Fittings and configuration
See the technical drawing on this page for fitting locations and sizes along with the full dimensional layout. Fitting and gasket configurations can vary on a tank like this, so before you order, call 866-418-1777 to confirm the supplied outlet, lid, and gasket setup matches what your install needs. It is a five-minute conversation that prevents a return.
Freight and ordering
This 250 gallon vertical storage tank ships LTL freight on a pallet, quoted live to your ZIP code. Norwesco molds this line at plants across the country, so your order will route from the nearest of Burnet TX, Fairfield TX, Griffin GA, Hanford CA, Lancaster OH, Owego NY, Shawnee OK, Sheldon IA, St. Bonifacius MN, Tooele UT, or Washougal WA. Because freight on a tank this size depends heavily on the distance from that plant to your door, get your exact number from the Freight Cost Estimator before you buy, or call 866-418-1777 with any questions about this Norwesco vertical tank.
