The Enduraplas 550 gallon beige vertical water storage tank (model TLV00550BE) is a straightforward choice for rural fire-water reserves, ranch and irrigation supply, rainwater collection, and any job that needs bulk water held in a compact footprint. It stands 52 inches tall on a 60 x 60 inch base, holds 550 gallons, and is molded from beige polyethylene with a 1.1 specific gravity rating, so it handles ordinary water storage with real margin to spare. The single most important number on this page is the foundation figure: build your pad to the rated 5,046 pounds of contents, not the 4,587 pounds that plain water alone weighs.
Will it work for your site?
This is a vertical water tank molded from polyethylene and rated to 1.1 specific gravity, meaning it is built for fluids up to 1.1 times the weight of water. Plain water sits at 1.0, so you have headroom for ordinary water service. Filled, the water alone weighs about 4,587 pounds, while the tank itself is rated to carry up to 5,046 pounds of contents. At 52 inches tall on a 60 x 60 inch footprint, this is a short, wide vertical storage tank rather than a tall, narrow one, so it sits stable and the outlet rides low to the pad. That low fitting height is worth noting if you are planning a gravity feed, since it limits available head, so account for it when you lay out your plumbing. Run the numbers with the Tank Sizing Calculator and the Tank Sizing Guide to confirm 550 gallons covers your draw-down, and see the technical drawing on this page for fitting locations and exact dimensions before you set any connections.
Set it on the right foundation
A full tank puts well over two tons on the ground, so the pad does real work. A level, properly sized concrete or compacted base keeps the tank from settling unevenly and stressing the shell. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework, and once the base is set, run the steps in our hydrostatic test methodology to fill in stages, watch for pad settlement, and check every fitting for leaks before the tank goes into service.
The mistake to avoid
Size the foundation to the rated 5,046-pound contents weight, not the 4,587-pound full-water figure. The lower number is what plain water weighs; the higher number is what the tank is rated to hold, and that is what your pad and any anchoring need to be engineered for. Building to the water-only weight leaves no margin if you ever store something denser within the 1.1 rating, or if you simply want the foundation rated the way the tank is. If this tank is headed into a rural or remote fire-protection role, our guide on fire-water reservoir tank design covers NFPA 22 sizing discipline and freeze protection so the reserve is there when you need it.
