The Enduraplas 1100 gallon vertical liquid storage tank gives you 1,100 gallons of above-ground bulk water capacity in a 60-inch round footprint that stands 97 inches tall. It is a polyethylene vertical tank carrying a 1.9 specific gravity rating, which means the green wall is built for heavy liquids well beyond plain water. For agricultural irrigation, fire-water reserve, and rainwater catchment, that rating is headroom you will never stress; for a vertical storage tank holding water, this is as conservatively engineered as the spec gets. The real benefit of the 1.9 wall is future-proofing: if you ever repurpose this tank for fertilizer, liquid feed, or any heavier-than-water liquid down the line, it already covers it - the natural-white 1100-gallon siblings rated for lighter liquids do not.
Will this tank work for your site?
The hard numbers come from the spec sheet and the technical drawing on this page, not estimates. Footprint is 60.0 x 60.0 inches and overall height is 97 inches, so confirm your pad and any doorway, roofline, or overhead clearance before you order - 97 inches tall needs honest headroom for delivery and for the inlet on top. One thing worth checking: this is the 60-inch-diameter, 97-inch-tall configuration. There is also an 87-inch-tall, 53-inch-diameter version of the 1100-gallon vertical tank (see the 87 x 53 natural white buyer's guide), so if 97 inches of overhead clearance is tight, that taller-but-narrower 87-inch unit may fit where this one will not - they hold the same nominal gallons but are not interchangeable on footprint or height. Plan the foundation around the loaded weight, not the empty shell: filled with water this tank carries roughly 9,174 lb, and at its full 1.9 SG rating it can hold up to about 17,431 lb of contents. That is the number your concrete pad has to carry. Size a level slab that extends a few inches past the base on all sides - plan for a minimum of roughly 66 x 66 inches so the full 60-inch base is fully supported with margin. Our concrete pad sizing guide walks the ACI 360R-10 framework for the engineered number, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 1,100 gallons is the right volume before you commit.
The mistake to avoid
The classic error on a high-SG vertical tank is under-building the foundation because you only picture water weight. Spec your pad and footings for the full rated contents load, support the entire base, and keep the tank level - an unsupported edge or a soft pad is what cracks a poly tank over time, not the liquid inside it. The 1.9 SG green wall is rated for that load; the ground under it is on you. One more verification step before you order: fitting configuration - inlet, outlet, and vent sizes and placement - is confirmed off the technical drawing on this page, so call 866-418-1777 to verify the exact fittings match your plumbing before you commit. If this tank is headed for rural fire-water or remote-site reserve duty, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection so the reserve is there when it is needed.
