The Enduraplas 911100-1.2-BLK is an 1100-gallon vertical water storage tank molded in black polyethylene, standing 72 inches tall on a 72-by-72-inch footprint. If you are staging bulk water for a rural fire reserve, an irrigation train, or a rainwater and reuse aggregation system, this is a straightforward vertical bulk-storage body sized to hold 1100 gallons in a compact square footprint.
Will it work for your site
The dimensions here are launch-verified: 72 inches in height, 72 inches across the width and length, giving you the 72.0 x 72.0 footprint you need to lay out a pad. Plan your slab to that square before the tank arrives. Filled to 1100 gallons of water, this tank carries a full water weight of 9,174 pounds, so the foundation under it has to carry roughly four and a half tons in a concentrated square. Do not set a tank this size on bare soil or a hand-poured patch. Size the pad deliberately - our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide walks the ACI 360R-10 framework for exactly this load. If you are still confirming that 1100 gallons is the right volume for your draw-and-refill cycle, run the numbers through our Tank Sizing Calculator and Tank Sizing Guide first.
The mistake to avoid
This is a vertical water storage tank, and the full water weight of 9,174 pounds assumes water. It is sold for water service, not for heavier chemical liquids. If your stored liquid is denser than water, this body is the wrong choice and you need a tank rated for the higher specific gravity - confirm the specific-gravity rating for your fluid before you buy, and keep this one on water. The other common miss is skipping acceptance testing after install: before you trust a new 1100-gallon vertical tank, fill it and hold it. Our Hydrostatic Test Methodology guide covers the water-fill discipline, pad-settlement monitoring, and hold-time math that catch leaks and foundation problems on day one instead of month six.
Fit for fire reserve and water reuse
An 1100-gallon black vertical is a common building block for private fire-protection reserves and for reuse-capable storage trains. If this tank is headed for a rural or remote fire-water reservoir, our Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, and HVAC condensate aggregation, our Industrial Water Reuse Tank Topology guide shows where a vertical body like this sits in a quality-banded storage train. Check the outlet and lid layout against the technical drawing on this page before you plumb.
