The Norwesco 7800 gallon black heavy-duty vertical storage tank is built for bulk water storage at scale, holding 7,800 gallons in a single vertical footprint of 119 by 119 inches and standing 176 inches tall. It is molded from black polyethylene and carries a 1.9 specific gravity rating, which is Norwesco's heavy-duty ceiling for this vertical storage tank line.

Will it hold what you need it to?
Filled with water, this tank carries roughly 65,052 pounds of contents. The 1.9 SG rating supports contents up to about 123,599 pounds, which is 1.9 times the weight of plain water, so you have real headroom above water service for denser liquids. Run the numbers against your own liquid before you commit using the Tank Sizing Calculator, and review the Tank Sizing Guide if you are weighing this against a different capacity. One thing to settle before you order: confirm the outlet, lid, and fitting configuration for this specific unit by checking the technical drawing on this page or calling 866-418-1777, since fitting layout drives how it ties into your system.
The mistake to avoid: foundation, not the tank
A vertical storage tank this size is only as sound as what it sits on. At full water weight near 65,000 pounds, this footprint concentrates serious load across a 119 by 119 inch base, and a tank loaded toward its 1.9 SG ceiling carries nearly double that. The common, expensive error is undersizing or under-engineering the pad. Read Concrete Pad Sizing for Above-Ground Polyethylene Tanks before you pour. If this is feeding a private fire-protection system, the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, the Industrial Water Reuse Tank Topology guide maps quality-banded storage trains.
Freight on a tank this size
This Norwesco tank ships LTL freight, quoted live to your ZIP code from the nearest of two Norwesco plants: Hanford, California, or St. Bonifacius, Minnesota. The serving plant, and therefore your freight origin, is confirmed at quote time, so the California-versus-Minnesota decision is resolved before you commit. Because of its size, freight is a real line item worth pricing first: get an exact number with the Freight Cost Estimator or call 866-418-1777 and we will quote it for you. The list price shown here is before freight.
