The Norwesco 6502 Gallon Vertical Liquid Storage Tank is a large-capacity vertical built for above-ground bulk water storage where you need a tall column of reserve volume in a tight circular footprint. Before anything else, hit the numbers that disqualify a site: it stands 196 inches tall (16.3 feet), sits on a 102-inch-diameter base, and holds 6,502 gallons. Filled with water it weighs 54,227 lb, and at its full rating the maximum rated contents weight is 81,340 lb. This is a Norwesco vertical storage tank rated to a 1.5 specific gravity - higher than the 1.0 to 1.3 typical of plain water tanks - which is the premium spec here, not an afterthought.
Will it work for your site?
Confirm two things up front: vertical clearance and the slab. At 16.3 feet tall, this tank needs open overhead to set it upright and reach the lid, so check building height, doorways, and overhead obstructions along the install path. Size the pad to fully support the 102-inch-diameter circle with margin, and engineer it for the load: the slab does not carry the 54,227 lb water fill, it has to tolerate the 81,340 lb max-rated contents weight. Build for the rating, not the day-one fill. Our concrete pad sizing guide walks the ACI framework for above-ground polyethylene tanks, and if you are still narrowing capacity the Tank Sizing Calculator and Tank Sizing Guide help you match volume to demand.
Fittings and configuration
Confirmed inlet, outlet, and fitting placement for this tank are quoted and verified at order rather than fixed in a generic spec sheet - so size your fill line and outlet against the configuration we confirm for your unit, not an assumption. See the technical drawing on this page for dimensional callouts, and call 866-418-1777 to lock fitting size and location before you build the plumbing. The 1.5 SG rating gives you roughly 50% structural headroom over water, which means real margin for denser additives or future re-purposing up to the 81,340 lb cap - but note that anything beyond plain water makes gasket and fitting material plus a chemical-resistance review a separate sign-off, not something the SG rating covers.
What is it good for, and the mistake to avoid
A 6,502-gallon vertical at this height is a workhorse for rural and remote bulk water: irrigation reserve, livestock supply, process make-up water, and private fire-protection reservoirs. If fire water is the driver, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. For grey-water, rainwater, and HVAC condensate aggregation, the water-reuse tank topology guide shows how a vertical of this size anchors a quality-banded storage train; a full walkthrough lives in the 6502 Gallon Vertical Liquid Storage Tank buyer's guide. The mistake to avoid: treating the 1.5 SG rating as a chemical-compatibility statement. It describes what the wall can structurally bear, not what the polyethylene resists - for water service you have comfortable margin, but for anything denser or chemically active the rating only confirms the tank can carry the weight, never that it tolerates the contents.
