The Enduraplas 1125 Gallon White Vertical Storage Tank is a polyethylene vertical storage tank built for bulk water and liquid storage where you need real capacity in a low-clearance footprint. It holds 1,125 gallons and measures 85 inches wide by 85 inches long by just 56 inches tall in Enduraplas natural white. That 56-inch height under an 85-inch width makes it an unusually squat vertical for this volume, which is a real advantage for low-clearance sites: basements, under eaves, or inside containment with a lid. If you have been searching for a white vertical storage tank that handles serious volume without standing tall, this is the size that does it.
Will it work for your site?
Confirm three numbers before you buy. First, footprint: this tank occupies an 85.0 x 85.0 inch base, so measure your pad, slab, or containment area against that square. Second, weight when full: water alone brings the loaded tank to roughly 9,382 pounds, which drives your foundation and pad design. Third, the specific gravity rating of 1.9 is a structural headroom number, meaning the shell is rated to carry contents up to a maximum of about 17,827 pounds. That ceiling is about weight, not chemical service. For any liquid other than water, confirm chemical compatibility and gasket and fitting material before use. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 1,125-gallon capacity matches your draw and refill cycle before committing to a footprint.
Foundation and placement
At nearly 9,400 pounds full of water, this is not a tank you set on bare soil. A poured pad sized to the 85 x 85 inch base carries the load and keeps the tank level, which matters for accurate level readings and even wall stress. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that slab right. If this tank is going into a rural fire-protection reserve, our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection for cold-climate service. For grey-water, rainwater, or HVAC condensate aggregation, see our industrial water reuse tank topology guide.
The mistake to avoid
The most common error on a tank this size is under-building the base. Use one clean rule: if you will ever store anything denser than water, size the pad, anchoring, and any secondary containment to the maximum rated weight of 17,827 pounds; if it is water only, the 9,382-pound figure governs. The 1.9 specific gravity rating means the shell can structurally carry heavier-than-water contents, but the limit is the weight, not just the volume, so build to the real number you intend to load. Before you plumb anything, confirm fitting sizes and outlet placement for your unit by calling 866-418-1777, since that configuration is verified at order rather than assumed.
This Enduraplas vertical tank ships LTL freight from our Converse, TX plant, which is a short LTL lane for Texas and South-Central buyers and a real cost advantage worth checking.
