The Enduraplas 1750 Gallon Vertical Water Storage Tank is a flat-bottom polyethylene tank built for steady bulk water storage where you need real volume in a compact footprint. It stands 89 inches tall on an 85 x 85 inch base, so it holds 1,750 gallons while occupying just over seven feet square of pad. Full of water, this tank weighs roughly 14,595 pounds — the number your pad and site plan have to answer to before anything else.
Does it work for your site?
This is a vertical bulk water tank — the workhorse shape for non-potable water holding, well-water buffering, rainwater capture, irrigation supply, and fire-water reserve. It is rated for water and water-based non-potable service; a specific-gravity rating is not published for this unit, so call 866-418-1777 before storing anything heavier than water. The tank comes with a 2 inch threaded fitting for your plumbing tie-in and a 16 inch lid for fill, inspection, and access. The 2-inch threaded outlet takes a standard 2-inch bulkhead or male adapter, and the 16-inch lid is your fill and inspection port — confirm both against the technical drawing on this page before you buy plumbing. At the 85 x 85 inch footprint and 89 inch height, plan vertical clearance for the lid and any overhead fill line. Use the Tank Sizing Calculator and the Tank Sizing Guide if you are still deciding between this and a neighboring gallonage. Color and opacity are not specified for this listing — confirm on order if UV or algae control matters for outdoor water storage.
Pad and install
The whole load rides on the base, so a flat, fully-supporting foundation is not optional at this size — 14,595 pounds of water demands it. That fill spread across the 85 x 85 inch footprint (about 50 square feet) works out to roughly 291 pounds per square foot, or about 2 psi average bearing load, which is the number to hand your pad designer. Our guide to concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework, and after set the hydrostatic test methodology covers water-fill acceptance, settlement monitoring, and fitting leak checks before you commit the tank to service.
The mistake to avoid
The common error at this volume is under-building the pad or setting the tank on uneven ground — a vertical poly tank supports its entire fill weight through the floor, and a soft or high spot concentrates stress the wall was never meant to carry. If this tank is going into a fire-protection or rural reserve role, our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection, and for reclaimed supply see our water reuse topology guide.
