The Enduraplas 1150 Gallon Vertical Water Storage Tank (SKU TC1150IW-GREEN) is a bulk polyethylene tank built for above-ground, non-pressurized water storage — rural water reserves, fire-water reservoirs, rainwater and industrial reuse trains, and general water storage duty. It holds 1,150 gallons in a tall vertical shell measuring 48 inches in diameter by 156 inches tall, molded in green to match the TC1150IW-GREEN SKU. Because the body is a true cylinder, its footprint is a 48-inch-diameter circle, not a square pad.
Will it work for your site?
Start with the height: 156 inches is 13 feet tall. That clears most standard overhead doors and many pole-barn eaves, so confirm your building opening, tilt-up erection room, and delivery-truck offload height before you order. Verified dimensions are 48 in diameter by 156 in tall, a slender 3.25-to-1 aspect ratio that concentrates weight over a small pad area. Filled to capacity, the tank plus water weighs approximately 9,591 lb, so the supporting surface has to carry that load without settling. A level, continuous concrete pad is the right foundation — our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground poly tanks. If you are still confirming the right capacity for your draw-and-refill cycle, run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide. See the technical drawing on this page for the dimensioned layout before you pour a pad or set anchors.
Sizing it into a system
At 1,150 gallons this vertical poly water tank sits in the mid-bulk range that fits rural and remote fire-protection reserves and reuse storage without jumping to a large flat-bottom footprint. For private fire-water service, our guide on fire-water reservoir design covers NFPA 22 sizing discipline and freeze protection for cold-climate installs. If you are aggregating grey-water, rainwater, or HVAC condensate, the industrial water reuse topology guide shows how a tank this size fits a quality-banded storage train.
The mistake to avoid
With a 13-foot-tall, 48-inch-diameter shell, the tall-and-narrow geometry works against you when the tank is empty and wind-exposed — plan tie-downs or ballast for the empty condition, not just the full one. And do not skip the acceptance test on a new install: commission the tank with a controlled water fill and a hold, watching for pad settlement and fitting leaks before you put it into service. The hydrostatic test methodology guide lays out the water-fill discipline and hold-time math. Filling a tall vertical tank on an under-built or unlevel pad is where most avoidable failures start.
