The Norwesco 1100 Gallon Black Heavy Duty Vertical Storage Tank is a 1,100-gallon polyethylene vertical tank built for bulk water and high-density liquid storage. Its black polyethylene shell carries a 1.9 specific gravity rating, the spec that defines this heavy-duty Norwesco tank. The geometry is unusual for this capacity: 87-inch diameter on an 87.0 x 87.0 inch footprint with a 53-inch overall height, making it wider than it is tall. That squat profile gives 1,100 gallons a low center of gravity, which helps on high-wind or seismic sites and on installs where overhead clearance is limited.
Will this Norwesco vertical tank work for your site?
Confirm three things before you commit. First, the footprint: this tank occupies an 87 x 87 inch square of pad, and at full water it carries roughly 9,174 pounds of contents on that area. Plan your pad accordingly - our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide walks through the ACI 360R-10 framework for above-ground poly tanks. Second, the capacity: if you are not sure 1,100 gallons matches your draw and refill cycle, run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide. Third, contents weight: with the 1.9 specific gravity rating, this tank is rated to carry contents up to roughly 17,431 pounds - nearly double the 9,174-pound weight of plain water - so you can store liquids up to 1.9 specific gravity in this same tank without exceeding the wall rating. That headroom is the genuine premium spec on this heavy-duty model.
The mistake to avoid: matching the specific gravity to your liquid
The number that trips up most buyers on a heavy-duty vertical storage tank is specific gravity. This tank is rated for liquids up to 1.9 specific gravity. Water is 1.0, so for water storage you have a large safety margin. If you intend to store something denser than water, check the liquid's specific gravity against the 1.9 rating before you order - that single spec determines whether the tank wall can carry the load over its service life. Do not assume a higher number; a liquid heavier than the rating shortens the life of any poly tank. The pack data does not list this model's fitting and gasket configurations, so call 866-418-1777 to confirm available fitting and gasket options for your application before ordering.
Common uses
This is a workhorse vertical storage tank for bulk water reserves, agricultural and rural water supply, and industrial process water. For rural fire-protection storage, our Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate sites, and if you are aggregating grey water, rainwater, or HVAC condensate, the Industrial Water Reuse Tank Topology guide maps how to band storage by quality. See the technical drawing on this page for the full dimensional layout.
