The 140 Gallon Vertical Liquid Storage Tank from Norwesco is a tall, narrow-footprint polyethylene tank built for above-ground liquid storage where floor space is tight but vertical clearance is available. It stands 73 inches tall on a 25-inch diameter base, holding 140 gallons in a single upright vessel. With a 2.92:1 height-to-diameter profile, this Norwesco vertical tank packs real capacity into a 25-inch circle of floor, which is why it shows up so often when buyers search for a vertical storage tank that fits a tight equipment room or pump house.
Will this tank work for your job?
Filled with plain water at a specific gravity of 1.0, the tank carries roughly 1,168 pounds of contents. The tank itself is rated to a 1.9 specific gravity, so its maximum rated contents weight is about 2,218 pounds. That 2,218 lb figure is your controlling design load, not the water number, and it gives you roughly 1,050 pounds of contents headroom for liquids heavier than water. Size your pumps, anchor loads, and pad reinforcement off the 2,218 lb maximum, not the 1,168 lb water weight. The 25-inch diameter footprint is what makes this size attractive in pump houses, equipment rooms, and skid layouts where a wider tank simply will not fit. To confirm this is the right size for your draw rate and storage duration, run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide. We also publish a full 140 Gallon Vertical Liquid Storage Tank buyer's guide that walks through common applications for this exact model.
Mounting, pad, and fitting verification
At 73 inches tall on a 25-inch base, this is a top-heavy profile when full, so a level, fully supporting foundation is not optional. The full-load weight of 2,218 pounds bearing on a 25-inch-diameter base works out to roughly 490 square inches of bearing area, or about 4.5 psi of static pressure at full rated load. Hand those numbers to whoever sizes your pad. Our guide on concrete pad sizing for above-ground polyethylene tanks covers the ACI framework for getting that foundation right. One important note: outlet and fitting size and locations are not specified in this listing data. Confirm them from the technical drawing on this page, or call us at 866-418-1777, before you plumb your connections.
Common applications
This vertical tank suits private fire-water reservoirs, industrial water reuse trains, and general bulk water storage. For remote or rural fire-water sites, our piece on fire-water reservoir tank design covers NFPA 22 sizing discipline and freeze-protection engineering. That cold-climate use case is worth thinking through here: a tall, slim 73-by-25-inch vessel has a small surface-area-to-volume ratio, so spec your heat-trace and insulation off the real geometry rather than a generic rule of thumb. For grey-water, rainwater, and HVAC condensate aggregation, see our industrial water reuse tank topology guide.
Mistake to avoid
The most common error with a tall, slim vertical tank is underestimating the foundation. Empty, this tank is easy to move; full at 2,218 pounds of rated contents concentrated on a 25-inch base, it loads a lot of weight onto a small footprint. Do not set it on bare soil, gravel, or an undersized pad, and never let it stand on an uneven surface that loads one edge. Confirm a level, full-contact pad before filling.
This tank ships LTL freight from the single Norwesco plant in Lancaster, Ohio, with freight quoted live to your ZIP. Because there is only one origin for this SKU, transit and cost scale with distance from Ohio, so a Texas or California ZIP will quote higher than a Midwest one.
