The Norwesco 8400 Gallon Vertical Liquid Storage Tank stands 187 inches tall on a 120-inch diameter footprint, making it one of the larger single-tank options for bulk water, agricultural, and process storage. Molded from polyethylene with a 1.5 specific gravity rating, this natural white vertical tank lets you read liquid levels through the translucent wall, and the high SG rating means it handles fluids heavier than water without de-rating. Below are the numbers you need to plan the pad, the rigging, and the freight.
Will it work for your site?
This vertical storage tank holds a full 8,400 gallons. Filled with water, the contents alone weigh roughly 70,056 pounds; at the tank's maximum 1.5 specific gravity rating the rated contents weight climbs to about 105,084 pounds. In practical terms, 1.5 SG means the tank is rated for contents up to about 12.5 pounds per gallon (1.5 x 8.34 lb/gal water) - that per-gallon ceiling, not the total, is what you size against for a denser fluid. Plan the foundation accordingly: a fully loaded tank this size needs a level, engineered concrete pad rated for that load across the entire 120-inch diameter footprint. Because the tank is delivered and set upright, also confirm your access route and any gate or doorway clears more than 120 inches wide plus rigging room, and check overhead clearance against the 187-inch height for both delivery and fill plumbing. If you are sizing this against a smaller Norwesco vertical tank, the Tank Sizing Calculator and Tank Sizing Guide walk through capacity, footprint, and weight tradeoffs.
Confirm fittings and the right build before you order
This listing does not specify outlet, bulkhead, or vent fittings, or gasket material, so confirm fitting size, placement, and gasket compatibility for your fluid before ordering rather than assuming a standard plumbing schedule - see the technical drawing on this page and call 866-418-1777 if you need it verified. One more check on a tank this large: there are two near-identical 8,400-gallon Norwesco builds, a 120" x 187" model and a 119" x 188" variant, so make sure you are ordering the 120" x 187" build that matches your pad and clearance plan.
How it ships
A tank this size ships LTL freight on its own, and the origin point drives your transit time and cost. This Norwesco vertical tank ships from the nearest of two plants - Albertville, Alabama or Fairfield, Texas - so eastern and southeastern ZIPs typically route from Alabama while central and western ZIPs route from Texas. Freight is quoted live to your ZIP rather than bundled into the list price. Run your address through the Freight Cost Estimator for a current quote, or call 866-418-1777 and we will route it from whichever plant lands closest to you.
The mistake to avoid
The most common error on a tank this large is under-building the pad. The 1.5 specific gravity rating is what lets this tank hold heavier-than-water liquids, but that same capability means a full tank can bear over 105,000 pounds at the maximum rated content density. Sizing the slab for a water-only load and then storing a denser fluid is how foundations crack and tanks fail. Decide what you are actually storing first, convert it to pounds per gallon against that 12.5 lb/gal ceiling, then build the pad for the heaviest case.
