This is a 550-gallon vertical liquid storage tank from Enduraplas, molded in black polypropylene for above-ground bulk water and liquid storage. It stands 83 inches tall on a 46-by-46-inch footprint, so it slots into a compact pad while holding a working reserve for rural water, fire-protection make-up, rainwater, or process supply. The black opaque wall blocks light, which suppresses algae growth in stored water — a real advantage over translucent tanks when the liquid sits for a while. Dimensions on this tank are verified, which matters when you are laying out a pad or fitting it under a roofline or inside a containment area.
Will it work for your site?
Filled to 550 gallons of water, this tank carries roughly 4,587 pounds. That full-water weight is the number your foundation has to support, not the empty shell, so size the pad and any structural deck around it. On that 46-by-46-inch square footprint, a flat, level, fully-supporting base is the requirement, and a poured pad is the common answer — our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground poly tanks. Note the height: at 83 inches, the tank clears a standard 84-inch doorway or roofline by only about an inch, so confirm your vertical clearance before ordering it for a low ceiling or a covered enclosure. If you are still confirming whether 550 gallons is the right band for your draw-and-refill cycle, run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide. See the technical drawing on this page for the fitting and dimensional layout, and check it before ordering plumbing or valves so your connections match what is molded in.
How it ships
A tank this size ships LTL freight on a pallet, not by parcel. Freight is quoted live to your delivery ZIP rather than bundled into the list price, so you see the real number for your location. Get a rate from the Freight Cost Estimator or call 866-418-1777 and we will quote it with you. Have a forklift or another way to receive several thousand pounds on a truck, since LTL delivery is curbside.
The mistake to avoid
The common error on a vertical tank this tall is treating the pad as an afterthought. At 83 inches and about 4,587 pounds full, an uneven or undersized base lets the tank load unevenly and can stress the shell over time — set it on a level, fully-supporting foundation from day one. This tank is molded in polypropylene rather than crosslinked polyethylene, so before storing anything other than water, confirm the resin and its rating for your specific liquid; heavier-than-water or chemical service in particular calls for verified compatibility on the actual liquid, temperature, and concentration.
