The Enduraplas 1100 Gallon Vertical Liquid Storage Tank (SKU 911100-1.9-NAT) is a white polyethylene tank built for bulk water and liquid storage where you need real volume in a compact footprint. It holds 1,100 gallons and stands on a square 72 in x 72 in base at 72 in tall, so it plans cleanly against a pad, a containment ring, or the corner of a pump house. What sets this unit apart is its 1.9 specific-gravity rating: the tank wall is engineered for liquids up to 1.9 SG, well above plain water at 1.0, so it covers denser liquids without moving to a heavier-duty tank. If you are still confirming the volume you need for a haul-water, irrigation, or rural fire-reserve setup, run the numbers first with our Tank Sizing Calculator and the Tank Sizing Guide.
Will it work for your site?
This is a vertical bulk storage tank sized for full liquid loads and rated to 1.9 SG. Filled with water it carries 9,174 lb, and that figure is the number that drives your foundation. Set it on a level, continuously supported concrete pad or an engineered ring rated for the full 9,174 lb load - a vertical tank this size does not tolerate a soft spot or an unsupported edge under the base. Fitting, outlet, and lid specifications are not published in this listing, so verify outlet and bulkhead fitting size, gasket material, and lid size against the technical drawing on this page before you order any mating plumbing or overflow line. Dimensions are verified at 72 x 72 x 72, giving you a square six-foot footprint to design around.
Freight and delivery
An 1,100 gallon tank ships LTL freight on its own skid, and freight is quoted live to your ZIP - it is never rolled into the list price. Plan for a liftgate or on-site equipment to receive it, and check overhead clearances for a tank this tall. Get a real number for your address with the Freight Cost Estimator, or call 866-418-1777 and we will work the quote with you.
The mistake to avoid
The common error on a vertical tank this size is treating the pad as an afterthought. The 9,174 lb filled load sitting on a six-foot base concentrates real weight; an uneven or partially supported foundation lets the base flex and shortens tank life. Pour or verify a full-footprint pad rated for that filled weight before the tank arrives. If you are planning a rural fire-water reservoir, our guide on fire-water reservoir design and NFPA 22 sizing walks through the tradeoffs.
