The Enduraplas 4000 Gallon White Vertical Storage Tank is a natural-white polyethylene bulk-water tank built for high-volume stationary storage — irrigation supply, rural fire-water reservoirs, process water holding, and industrial water-reuse trains. It stands 124 inches tall on a 110-inch-diameter, 110 x 110 inch square footprint and holds 4,000 gallons, so a full tank of water carries roughly 33,360 pounds. That combination of a tall vertical profile and a compact round footprint is why it shows up so often when people search for a white vertical storage tank that fits a limited pad while still banking serious volume. Check the 110-inch diameter against your gate, doorway, and pad clearances before delivery day.
Will it work for your site?
This is a vertical storage tank in the truest sense: a tall vertical column suited to high-volume stationary storage and gravity-fed lines. The tank shell carries a 1.9 specific gravity rating, meaning the wall is engineered to hold contents up to 1.9 times the weight of water — a structural ceiling near 63,384 pounds of rated contents. For plain water at SG 1.0 you are well inside that envelope, which is exactly why this tank suits fire-reserve and reuse duty where the water sits for long periods. Fitting locations, bung sizes, and outlet placement are called out on the technical drawing on this page; review it against your plumbing plan before you order so the inlet, outlet, and overflow land where your site needs them. To confirm 4,000 gallons is the right bank size for your draw rate and refill cycle, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide.
Foundation and cold-climate planning
Two weights matter here, and they govern different things. The 63,384-pound figure is the SG 1.9 structural ceiling for the shell — the maximum rated contents load the wall is built to carry. For pad and foundation design on water service, use the 33,360-pound full-water weight; that is the real load your base will see. On a 110 x 110 inch footprint, that calls for a level, continuous, load-rated pad — see our guide on concrete pad sizing for above-ground polyethylene tanks for the ACI framework behind a pad that will not settle or crack. If this is a rural or remote fire-water reservoir, our write-up on fire-water reservoir tank design walks through NFPA 22 sizing discipline and freeze protection for cold-climate service. Planning a grey-water, rainwater, or condensate reuse system? The industrial water reuse tank topology guide shows where a tank this size fits in a quality-banded storage train.
The mistake to avoid
The most common error on a tank this size is treating the pad and the plumbing as an afterthought. A polyethylene shell expands and flexes as it fills; rigid, unsupported inlet piping and an out-of-level or undersized pad are what shorten tank life, not the resin. Support your fittings, plumb with flexible connections at the tank wall, and set it on a full-footprint pad rated for the loaded water weight.
