The Enduraplas 800 Gallon Vertical Water Storage Tank (SKU 900800-1.2-NAT) is a straight-wall polyethylene bulk-water tank built for general water duty on farms, jobsites, fire-reserve pads, and industrial reuse trains. It stands 114 inches tall on a 47 x 47 inch footprint, so it holds a full 800 gallons of vertical storage while occupying under 16 square feet of pad. Dimensions here are verified against the tank's launch spec sheet, not estimated, so you can lay out your pad and overhead clearance before the truck arrives. Confirm the final height, along with lid and vent access above the shell, against the technical drawing on this page before you frame any overhead structure.
Will it work for your site?
This vessel is spec'd for water service at a specific gravity of 1.0. It does not carry a published higher-specific-gravity or chemical rating, so any denser fluid or chemical duty must be verified against the manufacturer's rating before you order. Filled to capacity, the tank carries roughly 6,672 pounds of water on that 47 x 47 inch base. That works out to an average bearing pressure of about 3.0 psi across the footprint, which is the number a foundation engineer wants when sizing the pad. Treat the full-water weight as the governing figure for pad design and settlement. If you are still deciding between this 800 and a larger or smaller vessel, run your daily draw and refill through the Tank Sizing Calculator and the Tank Sizing Guide before you commit. For new installs, walk the acceptance step with our guide to hydrostatic test methodology so pad settlement and any fitting leaks show up on the first fill, not the first month.
Pad and cold-climate planning
Because the full-water load lands near three and a third tons, the pad under this tank is not an afterthought. Our breakdown of concrete pad sizing for above-ground polyethylene tanks walks the ACI framework for getting it right. If this vessel is going into fire-reserve or rural water-supply service, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate pads. Running grey-water, rainwater, or HVAC condensate through it? The water reuse tank topology guide shows where a vertical storage tank fits in a quality-banded storage train.
The mistake to avoid
The most common miss on a tank this tall is treating it like a squat tote. At 114 inches, this is a tall, narrow column of water, so a level, full-contact pad matters more than it does on a wide low-profile tank. An out-of-level base concentrates that 6,672-pound load and stresses the lower wall. Level the pad, support the full footprint, and confirm the shell is plumb before you fill. Check the fitting layout on the technical drawing on this page before you schedule any plumbing, rather than assuming a port location.
