The Norwesco 11000 Gallon Vertical Liquid Storage Tank in blue is one of the largest polyethylene vertical tanks built for bulk storage, holding 11,000 gallons in a footprint just 144 inches (12 feet) in diameter and standing 167 inches (just under 14 feet) tall. It carries a 1.9 specific gravity rating, which is unusually robust for a tank this size: the polyethylene wall is built to hold liquids substantially heavier than water. For rural fire reserves, agricultural irrigation, and industrial process water, this is a serious piece of storage infrastructure.
Will it work for your site?
Start with the load math, because at this scale it drives everything. Filled with water, this tank carries roughly 91,740 pounds of contents, and at its full 1.9 specific gravity rating it is rated for up to 174,306 pounds of liquid weight. That 1.9 rating is also a genuine capability lever: the same tank covers heavier-than-water service, like brine and many agricultural and process liquids, without stepping up to a different model. That said, 174,306 pounds is more than 45 tons, and a tank holding that load needs an engineered foundation. The 144-inch circular footprint and the contents weight together set the pad requirement, and our guide to concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework engineers use to size it. To check that 11,000 gallons is right for your draw-down and refill cycle, run the Tank Sizing Calculator or read the Tank Sizing Guide, and for a full walk-through of this exact tank see our 11,000 gallon vertical liquid storage tank buyer's guide.
Common mistake to avoid
The mistake at this size is treating the foundation and the offload as afterthoughts. A vertical tank this tall and heavy transfers enormous concentrated load to its base, and an under-built or unlevel pad is the single most common cause of premature failure on large verticals. The 167-inch height also means you need to confirm fill access and overhead clearance for the top inlet before delivery. And do not assume "it's just plastic, we'll roll it off": even empty, a 167-inch-tall by 144-inch-diameter tank cannot be hand-set, so plan the same crane or forklift access for offload that you plan for the fill. Outlet and fitting sizes are not fixed in this listing; they are confirmed per build from the technical drawing on this page and by phone at 866-418-1777 before you order. For a worked example of designing storage around a real reserve requirement, see our fire-water reservoir tank design guide, and if you are aggregating grey-water, rainwater, or HVAC condensate, the industrial water reuse tank topology guide covers staging multiple sources into one storage train.
Freight on a tank this size
An 11,000-gallon vertical tank ships LTL on a dedicated flatbed, and freight is quoted live to your ZIP rather than rolled into the list price. At 144 inches (12 feet) in diameter and nearly 14 feet tall, this is a wide load that often requires permitting, and you will need a forklift or crane rated for the height and diameter to offload it at your site. This Norwesco vertical storage tank ships from the Albertville, Alabama plant, so your freight cost depends on the distance from there to your delivery point and your site's offload capability.
