The Norwesco 850 Gallon Vertical Liquid Storage Tank (SKU N-42214) is a polyethylene vertical storage tank built for above-ground bulk water and liquid duty. It stands 118 inches tall on a 48-inch diameter footprint, so it stores serious volume without sprawling across your pad. Norwesco rates it to a 1.5 specific gravity, which means the tank wall is engineered to hold liquids up to 1.5 times the weight of water at full capacity. For straight water service, that gives you a comfortable margin of safety.
Will it work for your site?
At 850 gallons of plain water, the contents alone weigh 7,089 pounds, and the tank is rated to carry contents up to 10,634 pounds before you reach the 1.5 specific gravity ceiling. Those numbers matter long before you fill it: the entire load lands on a 48-inch-diameter circle, so the pad or foundation underneath has to carry roughly seven thousand pounds of water before you even add the weight of the shell. Confirm the tank's dry weight against the spec sheet and plan your slab for the full filled load, not the empty unit. If you are pouring a base, work through the concrete pad sizing framework first. Not sure 850 gallons is the right capacity for your draw rate or storage window? Run your numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit.
Common uses, clearance, and a sizing note
This is a workhorse vertical tank for non-potable water storage, rainwater capture, and process water holding. At 118 inches tall, just under ten feet, check your door, gate, and overhead clearance before delivery and at the final siting spot so the unit can be stood up and positioned without trouble. It is a popular size for rural and remote fire-water reservoirs, where storage volume and a small footprint both count; if that is your application, the fire-water reservoir design guide walks through NFPA 22 sizing discipline and freeze protection for cold-climate sites. For reuse setups covering grey-water, rainwater, and HVAC condensate aggregation, the industrial water reuse tank topology guide covers how to band and sequence storage. For the full rundown on this exact size, see the 850 Gallon Vertical Liquid Storage Tank buyer's guide.
The mistake to avoid
The 1.5 specific gravity rating is for the tank structure, not a license to store any liquid up to that weight. The fitting, gasket, and seal materials still have to be chemically compatible with whatever you put in it. Because fitting locations, sizes, and gasket material are not specified on this listing, confirm them directly against the Norwesco spec sheet for this SKU, or with us at 866-418-1777, before you order and before you finalize your plumbing plan.
