The Norwesco 6000 Gallon Vertical Liquid Storage Tank (SKU N-40226) is a polyethylene vertical storage tank built for high-volume bulk liquid duty, standing 182 inches tall on a 102-inch diameter footprint. It carries a 1.5 specific gravity rating, the spec that decides whether this tank is right for your liquid - more on that below. For ranch fire reserves, irrigation supply, process water, or any application where you need to bank thousands of gallons in a small footprint, this is a large-capacity vertical poly tank.
Will it work for your liquid?
Start with weight and the specific gravity rating, because at 6000 gallons the numbers are not small. Filled with plain water (SG 1.0), this tank holds roughly 50,040 pounds of contents. The 1.5 specific gravity rating means the tank wall is engineered to safely carry liquids up to 1.5 times the weight of water - a maximum rated contents weight near 75,060 pounds. That headroom is what lets the same shell handle denser liquids than water without overstressing the wall. The mistake to avoid: do not treat the SG rating as a free pass. Confirm your liquid's actual specific gravity is at or below 1.5, and remember the rating speaks to structural load, not chemical compatibility - a liquid can be light enough yet still attack polyethylene over time. If your liquid's specific gravity exceeds 1.5, this shell is not rated for it; call 866-418-1777 for a higher-SG-rated tank.
Fittings and seals
On a poly tank, the polyethylene shell is rarely the first failure point - the gasket and seal at each fitting usually are. The fitting, bulkhead, and gasket package for this tank (sizes, outlet placement, full-drain configuration, and elastomer type) is detailed in the technical drawing on this page; review it against your plumbing, and confirm the gasket material and torque are right for your liquid before you order. If anything is unclear, call 866-418-1777 to verify the fitting and gasket package rather than guessing.
Sizing and siting the tank
With a 102-inch (8.5-foot) diameter, this tank wants a properly engineered foundation. A level, continuously supported concrete pad is not optional here: design the pad and any ring-wall for up to roughly 75,060 pounds of contents (not the 50,040-pound water figure) if the tank will ever hold a denser liquid, plus the tank's own dead weight. Walk the load math and pad geometry in our concrete pad sizing guide before you pour. If you are still deciding on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match volume to your draw rate and refill cycle, and a deeper walkthrough of this exact model lives in our 6000 Gallon Vertical Liquid Storage Tank buyer's guide.
Common applications
This is a workhorse vertical storage tank for rural fire-water reservoirs, agricultural irrigation, and industrial water reuse. If you are designing a private fire-protection reserve, our guide to fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, and HVAC condensate aggregation, see our industrial water reuse tank topology overview.
Freight: this Norwesco vertical tank ships LTL freight, quoted live to your ZIP from the nearest stocking plant - Fairfield, TX; Hanford, CA; or St. Bonifacius, MN. A buyer close to one of those three points can see materially lower LTL than someone mid-continent, so run your ZIP through our Freight Cost Estimator before assuming this is an expensive haul, or call 866-418-1777 to lock in delivery. List price shown is before freight.
