The Norwesco 8400 Gallon Vertical Liquid Storage Tank stands 187 inches (15 ft 7 in) tall on a 120-inch (10 ft) diameter footprint. Molded in blue polyethylene with a 1.9 specific gravity rating, it is built to hold dense liquids near the top of the storage range, not just water. For rural fire-water reservoirs, municipal bulk storage, and irrigation, this is a high-commitment Norwesco vertical tank: filled with water it carries roughly 70,056 pounds, and at its maximum rated contents weight it is built to support up to 133,106 pounds of liquid. Plan the pad and the contents before you order.
Will it work for your site
The numbers that matter on a tank this size are the footprint and the load. At 120 inches (10 ft) in diameter and 187 inches (15 ft 7 in) tall, this vertical storage tank needs both real overhead clearance and a properly engineered base, so confirm crane or boom access and vertical room before the truck arrives. The 1.9 specific gravity rating is the key spec: it means the wall thickness is rated for liquids up to 1.9 times the weight of water, which is why this tank suits dense liquids rather than water alone. Use the full-water weight of 70,056 pounds as your baseline and the 133,106-pound max rated contents figure as your ceiling when you size the foundation. For a flat, level concrete pad correctly sized to that load, see our concrete pad sizing guide. If you are still choosing capacity, the Tank Sizing Calculator and Tank Sizing Guide walk through volume, footprint, and fill weight together.
Reference the technical drawing before you plumb
Fittings, gaskets, and bulkhead seals are not defined in this listing, so do not assume an outlet size or seal material. Fitting locations, outlet sizes, lid dimensions, the tank's own empty shipping weight, and exact wall and base detail are on the technical drawing on this page. Pull the empty weight to size your offload forklift or crane, and pull the fitting and outlet detail before you commit to pump placement, manway access, or piping runs, since a tank this tall changes where you can practically tie in. A 1.9-SG-rated wall does not by itself mean the gasket and seal materials are compatible with a dense or aggressive liquid, so match every seal to the chemistry of what you actually intend to store. For deeper background on this exact model, our complete buyer's guides for the 8400 gallon vertical at 120 x 187 and the related 119 x 188 configuration cover the details side by side. If this tank is destined for rural fire-water duty, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection.
The mistake to avoid
The most common error on a high-SG tank is under-building the foundation. Do not pour a pad sized for water weight when the tank can carry contents up to 133,106 pounds. Match the pad and any ring wall or compacted base to the densest liquid you actually intend to store, and confirm the contents fall within the 1.9 specific gravity rating before filling. A tank rated to 1.9 will handle water and denser liquids, but verify your specific product's density against that ceiling rather than assuming it falls inside the limit.
This Norwesco vertical storage tank ships LTL freight, quoted live to your ZIP. It ships from Albertville, AL or Fairfield, TX, and on a 70,000-plus-pound move your rate depends largely on which plant serves your region, so origin proximity is the biggest lever you have.
