The Norwesco 1100 Gallon Vertical Liquid Storage Tank is a blue polyethylene vertical tank built for above-ground bulk water storage on farms, rural fire-water reservoirs, and remote-site supply. It holds 1,100 gallons in a round body measuring 87 inches in outside diameter, putting a full footprint on an 87.0 x 87.0 inch pad. Filled with water it carries roughly 9,174 lb, so the foundation and siting decisions matter as much as the tank itself. Norwesco molds this model at eight plants nationwide, so it almost always ships from a plant near you.
Will it work for your job?
This is a true vertical storage tank molded from polyethylene with an 87 x 87 inch footprint and a 1,100-gallon working capacity. Confirm the overall dimensions - listed as 87 inches outside diameter by 53 inches overall height - against the technical drawing on this page before you finalize your install footprint. It is rated to a 1.9 specific gravity, which means the tank is built to hold liquids heavier than water, not just water: a buyer storing fertilizer or a denser solution does not need to size up to a heavier tank. That rating gives a maximum rated contents weight of about 17,431 lb. For water at roughly 8.34 lb per gallon you sit at around 9,174 lb full, well inside that envelope with generous headroom for storage and refill duty. If you are not certain this size fits your draw-down or refill cycle, run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you buy.
Fittings and the technical drawing
Fitting and outlet locations and sizes for this tank are shown on the technical drawing on this page. Match any bulkhead fittings and gaskets to that drawing before you plumb the tank, and confirm the outlet position works for your gravity-feed or pump setup. This blue model is the same 1,100-gallon vertical platform as the natural-white variants - two complete buyer's guides for the 1100-gallon vertical (parts 42591 and 40070) are linked on this page and walk through full specs and fitting detail. If you want to read your liquid level through the wall, the natural-white translucent version is the one to compare against this blue, opaque tank.
How it ships
This tank ships LTL freight, quoted live to your ZIP code. Norwesco molds this model at multiple plants - Fairfield, TX; Hanford, CA; Lancaster, OH; Owego, NY; Shawnee, OK; Sheldon, IA; Tooele, UT; and Washougal, WA - so your order leaves from whichever plant is nearest you, which keeps transit shorter and freight more reasonable. Because an 87-inch-diameter tank is a dimensional, low-density LTL load, get an exact number through the Freight Cost Estimator or by phone before you commit.
The mistake to avoid
The most common error on a tank this large is the foundation. A 1,100-gallon vertical tank full of water concentrates roughly 9,174 lb onto an 87-inch circle, so it needs a level, continuously supported, smooth pad - not bare soil, gravel high spots, or a ring that leaves the floor unsupported. Unsupported floor areas are the leading cause of premature stress cracking on large poly tanks. For a properly engineered base, work through our concrete pad sizing guide, and if you are planning a rural or remote fire-water reservoir, the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and cold-climate freeze protection for this exact role.
Listed before freight, this Norwesco 1100 gallon vertical storage tank ships LTL from the nearest of eight plants and is quoted live to your ZIP through the Freight Cost Estimator or by phone at 866-418-1777. Size it first with the Tank Sizing Calculator and Tank Sizing Guide, and plan the base with our concrete pad sizing guide.
