The Enduraplas 850 Gallon Vertical Water Storage Tank (SKU TC850XIW-NATURAL) is a straight-wall polyethylene tank built for bulk water storage where you need real volume in a modest footprint. It stands 124 inches tall on a 48-inch diameter base, so it holds 850 gallons within a 48.0 x 48.0 inch footprint. The SKU suffix XIW-NATURAL indicates a natural, translucent shell; confirm the exact color before you order if that matters for your install. If you are laying out a pad, a pump house, or a fire-water skid, that vertical geometry is the reason to pick this size over a shorter, wider tank.
Will it work for your site
This is a vertical storage tank sized at 850 gallons, verified at 124 in tall on a 48 in diameter base. The number that drives your pad and anchoring decisions is the full-water weight: filled with water this tank carries 7,089 pounds of water alone. That figure excludes the empty tank's dry weight, so add the tank's own weight for the total load imposed on your pad. All of it sits inside a 48 x 48 inch footprint, which concentrates the load, so the pad underneath has to be engineered to carry it without settling. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm 850 gallons is the right band for your daily draw and refill cycle before you commit.
The mistake to avoid: the pad
The common error on a tall vertical tank this size is under-building the foundation. More than 7,000 pounds of water on a four-foot square base, plus the tank's own weight, needs a level, load-rated pad, not gravel or bare soil that can wash out or tilt the tank over time. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework so your pad is dimensioned to the load. When the tank is set, run a proper acceptance fill using our hydrostatic test methodology to watch pad settlement and check every fitting before the tank goes into service.
Fit for the job
At 850 gallons in a vertical profile, this tank suits rural and remote water supply, including private fire-protection reservoirs covered in our NFPA 22 sizing guide, as well as reuse trains for grey-water, rainwater, and HVAC condensate aggregation detailed in our water reuse topology guide. Refer to the technical drawing on this page for the tank's dimensional layout.
