The Enduraplas 7011 gallon vertical liquid storage tank is a polyethylene reservoir built for large-volume water and dense-liquid duty, listed here in white. It measures 144 inches in diameter on a 144 x 144 inch footprint, stands 126 inches tall, and carries a 1.9 specific gravity rating, which is high for a vertical storage tank this size and the reason it can hold heavier-than-water contents without overstressing the wall. Note the squat profile: at 126 inches tall on a 144-inch diameter, this tank is wider than it is high, so confirm the footprint clears your pad before you commit. The spec sheet and the technical drawing on this page give you the dimensions you need to verify fit.
Will this tank work for your application?
The numbers that matter for a 7011 gallon vertical tank are footprint, height, and load. The footprint is 144 x 144 inches square, the height is 126 inches, and the contents are rated up to a 1.9 specific gravity. Filled with plain water this tank carries 58,472 pounds. At its maximum rated 1.9 SG contents it carries 111,096 pounds. Those weights are what you design the pad for, not just the empty shell, and the loaded weight is the single most common thing buyers underestimate on a tank this large. Plan a level, engineered concrete pad rated for the full loaded weight before delivery, and confirm your site access can take a tank with a 144-inch square base. If you are not certain the 7011 is the right capacity, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide first.
The specific gravity rating is the spec to respect
This Enduraplas tank is rated to 1.9 specific gravity, meaning it is engineered to hold liquids up to 1.9 times the density of water. That headroom is the reason to choose this build, but the rating is a ceiling, not a license to ignore the actual density of what you are storing. The decision is straightforward: if you are storing water only, the 1.9 rating gives you a generous structural margin and a long service life; if your liquid is denser than water, up to 1.9 SG, this is the build that carries that load safely. Either way, match your liquid's specific gravity to the 1.9 rating, and if you are storing anything other than water, confirm resin and gasket compatibility for that liquid before filling. Because no published fitting schedule ships with this tank, outlet and bulkhead fitting sizes and gasket material are confirmed per order by phone at 866-418-1777 rather than read off this page.
Freight on a tank this size
A 7011 gallon tank ships LTL freight, quoted live to your ZIP code. It moves from the nearest Enduraplas plant in our network, either Converse, TX or Neche, ND, so your freight cost depends heavily on which plant serves your region. As a rule, southern and south-central ZIPs pull from Converse, TX while northern and upper-Midwest ZIPs pull from Neche, ND. Get an exact number from the Freight Cost Estimator before you order, and plan for the two failure points buyers hit on a tank this large: a 144-inch square base typically requires flatbed delivery, plus a forklift or crane on site to offload, and an engineered pad rated for the full loaded weight under it. If you are building out a rural water reserve or private fire-protection supply, the fire-water reservoir design guide covers how a polyethylene vertical tank fits into that stack, including freeze protection for cold-climate sites near the Neche, ND origin.
