The Enduraplas 2100 Gallon White Vertical Storage Tank (SKU THV02100W) is a 2,100-gallon polyethylene vertical tank standing 100 inches tall on an 85 x 85 inch footprint, molded in Natural White. That footprint works out to roughly 50 square feet of pad holding 2,100 gallons - about 42 gallons per square foot - which is why this is a workhorse size for bulk water and liquid storage when you want real capacity without an oversized slab. Whether you are shopping for a vertical storage tank, a white vertical storage tank, or simply a dependable vertical tank, this is a proven size.
Does it work for your site?
Capacity is 2,100 gallons in a single vertical body on an 85.0 x 85.0 inch footprint, so plan a pad at least that wide before you order. The number to design around is weight. Filled with water this tank carries 17,514 lb, and at its maximum rated contents it reaches 33,277 lb. The tank wall is rated to a 1.9 specific gravity, meaning it can hold liquids heavier than water up to that density. Because 17,514 lb across 2,100 gallons works out to about 8.34 lb per gallon at water density, you can estimate any loaded weight as 8.34 x specific gravity x 2,100:
- SG 1.0 (water): about 17,514 lb
- SG 1.4: about 24,520 lb
- SG 1.9 (max rating): 33,277 lb
Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide, and before you pour concrete, read Concrete Pad Sizing for Above-Ground Polyethylene Tanks so the foundation matches your worst-case load.
Confirm you have the right 2,100-gallon footprint
There are several 2,100-gallon vertical tanks with different proportions, so check the dimensions before you buy. This one is 100 in tall on an 85 x 85 in base. If your site was specced around a taller, narrower body, compare against the 102 x 69 buyer's guide or the 87 x 89 buyer's guide to be sure the footprint matches your pad. For outlet and fitting placement on this tank, see the technical drawing on this page and confirm the layout against your plumbing before delivery. If this size is part of a fire-water reserve, the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate sites.
The mistake to avoid
The 1.9 specific gravity rating is a maximum, not a free pass. It tells you the heaviest liquid the tank wall can safely hold, but the load your pad and tie-downs actually see scales with the density of what you store. Sizing the slab for water at 17,514 lb and then filling toward the 33,277 lb ceiling with a denser liquid is how foundations crack. Match your concrete and anchoring to the real density of your contents, not to the water number.
