The 7800 Gallon Vertical Liquid Storage Tank from Norwesco is a large-volume polyethylene reservoir that holds 7,800 gallons in a vertical footprint just 119 inches in diameter and standing 176 inches (14 ft 8 in) tall. This is bulk storage for operations that have outgrown smaller tanks: rural fire-water reserves, irrigation and ag water, process and rinse water, and rainwater or reuse storage where a large volume of liquid needs a single, manageable footprint. Check that 14-foot-8 height against your overhead clearance, fill-pipe reach, and shipping route before you order.
Will this tank work for your job?
The tank is molded from polyethylene and carries a 1.5 specific gravity rating, meaning it is engineered to hold liquids up to 1.5 times the weight of water. That rating is real headroom above plain water: the same tank handles denser ag and process liquids in the water-adjacent range without stepping up to a different unit. The two weights that drive every planning decision are the loaded contents:
- Full of water: roughly 65,052 lb
- Maximum rated contents at 1.5 SG: 97,578 lb
Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the 7800-gallon size matches your draw-down and refill cycle before committing to a vertical storage tank this large. Refer to the technical drawing on this page for fitting locations and exact dimensional callouts.
Foundation: build for the full weight, not the empty shell
At a 119-inch diameter footprint and tens of thousands of pounds when full, this Norwesco vertical tank demands a properly engineered base. A flat, level, fully supporting pad sized for the loaded weight is not optional at this scale. The most common error on a tank this large is setting the empty shell, light enough for two people to position, onto a pad never built for what fills it: once full it concentrates the weight of a loaded semi onto a single circular footprint. Build the pad for the maximum rated contents weight, not the empty tank. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that foundation right.
Fire-water and reuse system planning
If you are sizing this tank for private fire protection, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. If you are aggregating grey-water, rainwater, or condensate into a reuse train, our industrial water reuse tank topology guide and the full 7800 Gallon Vertical Liquid Storage Tank buyer's guide cover system layout in depth.
