The Enduraplas 1550 gallon vertical liquid storage tank is a white polyethylene tank built for bulk water and liquid storage where footprint and capacity both matter. It holds 1,550 gallons in a compact 85 x 85 inch footprint standing 80 inches tall, and it carries a 1.9 specific-gravity rating, so it handles heavier liquids than a standard water tank rated at 1.0 SG. If you are comparing vertical storage tanks and want real headroom in the rating, this is a serious white vertical storage tank.
Will this tank work for your site?
Start with weight, because that is what dictates your pad and your placement. Filled with water, this tank carries roughly 12,927 pounds of contents. At its maximum 1.9 SG rating it is engineered to hold up to 24,561 pounds of contents, and that headroom is what lets you store liquids denser than water in the same shell. Either way, you need a level, continuously supported concrete pad rated for the full loaded weight across the 85 x 85 inch footprint. Do not set a tank this size on gravel, timbers, or a partial ring; polyethylene needs uniform bottom support or the floor will stress-crack over time. If you are still deciding on capacity, run your numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit to a footprint.
The mistake to avoid
Treat the 1.9 specific-gravity rating as a weight ceiling, not a reason to oversize. It confirms the shell can carry a dense liquid, but the number you actually design around is the loaded weight your pad and forklift can handle. Two practical checks before you order: size for your real draw and refill cycle rather than the biggest tank that fits the slab, and confirm the outlet and bulkhead fitting sizes and locations with us, since those are not listed in this tank's published data and we will not guess at them. For a rural or remote water-reservoir install, our fire-water reservoir design guide walks through NFPA-22 sizing discipline and cold-climate freeze protection. If you are weighing a step up in capacity, the 2000 gallon vertical tank guide covers the next size (verify its footprint against the 85 x 85 spec above, as dimensions differ by model).
Freight and next steps
This tank ships by LTL freight, quoted live to your ZIP code from the nearest stocking plant, either Converse, TX or Neche, ND. Because a tank this size is a dimensional freight item, the shipping cost swings widely by destination, so get your real number before you buy with our Freight Cost Estimator, or call us at 866-418-1777 and we will quote it for you. Have questions about pad prep, fittings, or whether this is the right vertical storage tank for your liquid? Reach out before you order, and we will make sure you get it right the first time.
