The Norwesco 7800 Gallon Vertical Liquid Storage Tank in black is a large-format vertical tank molded in high density linear polyethylene with a 1.5 specific gravity rating. At 119 inches in diameter and 176 inches tall, it stores 7,800 gallons on a 119.0 x 119.0 inch footprint, suiting it to rural fire-water reservoirs, agricultural irrigation supply, and industrial water reuse trains. Because freight on a tank this size is a major line item, it ships LTL from whichever of two plants lands the better rate to your ZIP: Hanford, CA or St. Bonifacius, MN.
Will it hold what you're storing
This is the spec to get right before anything else. Filled with plain water, the tank carries roughly 65,052 pounds of contents alone; at its full 1.5 specific gravity rating, the maximum rated contents weight reaches 97,578 pounds. The 1.5 SG rating means the walls are built to handle liquids up to one and a half times the density of water, which covers water and many heavier solutions. Here is the hard rule: if your liquid's specific gravity exceeds 1.5, this tank is not rated for it, so stop and request a higher-rated tank rather than assuming it qualifies. If you are storing anything other than plain water, confirm the actual specific gravity of your liquid against the 1.5 rating first.
Fittings, outlets, and what's in the box
Fitting layout, including outlets, manway, and vent placement, is configured per order rather than fixed. Before you purchase, call 866-418-1777 to confirm the outlet size and gasket material your install needs so the tank arrives ready for your plumbing rather than requiring rework. The technical drawing on this page shows the tank geometry and standard fitting locations for reference.
Pad, siting, and offload
A tank this size lives or dies on its foundation. The full 97,578-pound rated load lands on a 119-inch square footprint, so the pad must be fully supported, level, and continuous across the entire base; uneven or undersized support concentrates that weight and stresses the polyethylene. Size and reinforce the slab for the loaded weight before delivery using our concrete pad sizing framework, which walks through the ACI 360R-10 and ACI 318 boundaries for above-ground poly tanks. Offload matters just as much: at 176 inches tall this is an oversized, top-heavy lift, so confirm your crane or forklift has the reach and capacity for an empty tank of this height before the truck arrives.
Sizing this against your demand
Before committing to 7,800 gallons, confirm the volume matches your draw and refill cycle. Our Tank Sizing Calculator and Tank Sizing Guide help you work backward from daily demand to required storage, and the 7800 gallon vertical liquid storage tank buyer's guide covers layout and common applications for this format. If you are sizing for fire protection, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection, and the water reuse topology guide helps if this tank is part of a grey-water, rainwater, or condensate aggregation train.
This Norwesco vertical storage tank ships LTL on its own dedicated freight, quoted live to your ZIP from the nearest of Hanford, CA or St. Bonifacius, MN. Run your delivery ZIP through the Freight Cost Estimator for a live quote, or call 866-418-1777 and we'll route it from whichever plant lands the better rate. Plan offload equipment and pad readiness before it arrives.
