The Enduraplas 550 gallon vertical storage tank measures 52 inches tall on a 60-by-60-inch footprint and holds 550 gallons of water inside a polyethylene wall in natural white. It is unusually squat for its capacity - wider than it is tall - and that is the point: the wide 60-inch stance keeps the center of gravity low and the tank stable once it is full, instead of stacking volume into a tall, tippy profile.
Will it work for your application?
Spec line first: 52 in H x 60 in W/dia, 550 gallons, natural white polyethylene. Filled with water, the tank carries roughly 4,587 pounds of contents, so plan your base and plumbing around real load, not the empty weight. The shell is engineered to a 1.9 specific-gravity rating, which gives substantial structural safety margin over water's 1.0 - useful durability headroom for a tank that will sit outdoors and cycle full-to-empty for years. Whether you are setting up a fire-water reserve, irrigation supply, rainwater capture, or general industrial process water, run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide to confirm 550 gallons matches your draw-down and refill cycle before you order.
Siting and the mistake to avoid
The most common error with a vertical tank this size is setting it on soil, gravel, or an undersized slab. A full tank puts thousands of pounds across its 60-inch footprint, and an uneven or under-built base will rock the tank, stress the outlet, and crack fittings over time. Pour a level, full-footprint concrete pad sized to carry the load - our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and where the ACI 318 boundary sits. In cold climates, plan freeze protection before winter; the fire-water reservoir design guide covers freeze-protection engineering for cold-climate service even if fire suppression is not your primary use. For exact fitting locations and outlet placement, refer to the technical drawing on this page before you finalize the slab and plumbing layout.
Planning a reuse or harvesting system
If this tank is one node in a larger water program, the dimensions and weights above let you lay out the pad and connections before delivery. For grey-water, rainwater, or HVAC condensate aggregation, see our overview of industrial water reuse tank topology, and for rainwater capture specifically, the first-flush diverter sizing guide covers first-flush diverter sizing per the Texas Manual on Rainwater Harvesting.
This Enduraplas vertical storage tank ships LTL freight, quoted live to your ZIP code from the nearest of two stocking plants - Converse, TX or Neche, ND. That two-region coverage means southern and northern-tier ZIPs both route from a closer plant, which typically trims LTL cost versus a single-origin shipment. Get your number with our Freight Cost Estimator, or call 866-418-1777 and we will quote it to your ZIP and help confirm the right tank for your site.
