The Enduraplas 6250 Gallon White Vertical Storage Tank is a large-format polyethylene vertical built for high-volume bulk water storage where you need serious capacity in a single upright footprint. It holds 6,250 gallons in natural white polyethylene, stands 147 inches tall on a 120 x 120 inch base, and carries a 1.9 specific gravity rating. That 1.9 SG wall is the heavy-duty version of this tank - it is rated to hold contents up to 99,038 pounds, so there is no heavier-wall step-up to buy for water service. For plain water, which weighs roughly 8.34 pounds per gallon, you are filling well below that structural ceiling, giving you a wide margin at full volume.
Will it work for your site?
The footprint is a 10 ft x 10 ft base (120 x 120 in) standing 12 ft 3 in tall (147 in), so check door, gate, and overhead clearance early - the height matters for covered or indoor installs and for delivery-truck offload. Filled with water, the tank weighs about 52,125 pounds, so the pad underneath has to carry more than 26 tons without settling or cracking. A flat, level, engineered base is not optional at this scale. Before you pour, walk through our concrete pad sizing framework so the slab is matched to the full water weight rather than guessed. If you are still deciding between capacities, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to your actual draw and refill patterns.
Common uses and fittings
At 6,250 gallons this white vertical storage tank fits bulk water storage, irrigation supply, rural and remote fire-water reserves, and industrial process water. If fire protection is the driver, our guide to fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and freeze protection for cold-climate service. Fitting sizes and placements are not published for this unit, so confirm your inlet, outlet, and vent configuration with us at 866-418-1777 before you finalize plumbing - and refer to the technical drawing on this page. Reaching connections up to 12 feet high takes planning, so lock the fitting layout down before delivery day.
The mistake to avoid
The most expensive error on a tank this size is treating the pad as an afterthought. A 6,250-gallon vertical full of water puts more than 26 tons on the ground; an undersized or unlevel base leads to uneven wall loading and premature stress on the polyethylene. Engineer the foundation to the full water weight first, then confirm your fitting plan and site access before the truck arrives.
Freight
This tank ships by LTL freight from the Enduraplas plant in Converse, TX, quoted live to your ZIP code - freight is not included in the list price. At 12 ft 3 in tall on a 10 ft base, it moves as a dedicated flatbed or step-deck load and needs forklift or crane offload, not a liftgate, so confirm delivery access and unloading equipment ahead of time. Get an exact number in seconds with our Freight Cost Estimator, or call 866-418-1777 and we will quote delivery, offload options, and lead time for your site.
