The Enduraplas 1550 Gallon Vertical Liquid Storage Tank in faint green is a polyethylene vertical tank built for above-ground bulk liquid storage where you need real volume without pouring a vault. At 85 inches wide and deep by 80 inches tall, it holds 1,550 gallons on an 85.0 x 85.0 inch footprint. If you are sizing a reservoir for rural fire protection, irrigation, rainwater capture, or process makeup water, this vertical storage tank earns its pad space.
Will this vertical tank work for your site?
Start with the load, because that is what dictates your pad and your placement. Filled with water this tank carries roughly 12,927 pounds, and it is rated to a 1.9 specific gravity, meaning it can hold contents weighing up to about 24,561 pounds at maximum rated density. That 1.9 SG rating is a decision lever, not just margin: this is not a water-only tank. The same chassis rating that handles water also handles dense agricultural and industrial liquids up to 24,561 pounds of contents, so you are not locked in if your service changes down the road. For everyday water duty, that makes it a conservatively rated tank you are unlikely to over-stress. Use the Tank Sizing Calculator to match capacity to your draw-down and refill cycle, and the Tank Sizing Guide if you are weighing this against a taller or shorter vertical.
The squat footprint and the mistake to avoid
This 1550 is unusual: at 85 inches wide and 80 inches tall it is nearly as wide as it is tall, so it trades height for a wide, low-center-of-gravity base. That makes it easier to ladder and steadier when full, but it needs a full 7-by-7 foot pad to sit on. The most common error with a tank this size is setting it on an undersized or uneven base. At nearly 13,000 pounds full, it needs a level, continuous, full-diameter support surface; a partial pad or soft spots create point loads the polyethylene was never meant to bear, and that is where premature failures begin. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so your foundation matches the load. One more planning note: the top stands 80 inches (6 ft 8 in) off the pad, so plan your fill-line drop and a safe way to reach the lid before the tank is in place.
Fittings and fire-water service
Fitting configuration for this SKU, including bulkhead outlet size, lid diameter, and vent, is not published here, so confirm outlet size, gasket material, and lid diameter with us at 866-418-1777 before you plumb it. Matching your fittings and gaskets to your liquid and line size up front saves a return trip and a leak. If this tank is headed into a private fire-protection role, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. See the technical drawing on this page for the full dimensional view.
Freight
This 1550 ships LTL, freight-billed separately from the list price and quoted live to your ZIP. You ship the empty tank, not 13,000 pounds of water, but at this diameter it is a large-cube LTL load, so liftgate and delivery-appointment fees usually apply. It dispatches from the nearest of two Enduraplas plants, Converse, TX or Neche, ND, so a Texas or Midwest delivery typically moves shorter and cheaper than a coast-to-coast haul. Run your exact ZIP through the Freight Cost Estimator for a real number, or call us at 866-418-1777 and we will quote the lane, confirm liftgate and appointment needs, and walk you through pad prep. List price is shown before freight.
