The Chem-Tainer 850 Gallon Vertical Storage Tank is a black polyethylene tank standing 124 inches tall on a 48-by-48-inch square footprint. It carries a 1.5 specific-gravity rating, which for water service is straightforward reserve strength: the shell is built with margin well beyond the load of clean water, so it holds up under years of fill-and-draw cycles. For water storage, reuse, and rural supply duty, that extra wall integrity is what separates a long-life vertical tank from a thin-walled barrel.
Will it work for your site?
Full of water, this vertical storage tank carries roughly 7,089 pounds of contents, and that is the number to design your water install around. The 1.5 SG rating gives the tank a rated structural ceiling of about 10,634 pounds, a strength margin rather than an everyday operating target. The 48-inch square footprint keeps the base compact for a tank of this height, so it fits tight equipment yards, pump houses, and rural water rooms where floor space is limited. Because it stands 124 inches tall, confirm door and ceiling clearances at the install spot and check overhead room before delivery. If you are still weighing capacities and diameters, our Tank Sizing Calculator and Tank Sizing Guide walk through matching gallons, footprint, and weight to your slab.

Foundation and the mistake to avoid
The single most common error with a tall black vertical tank like this one is setting it on an under-built or uneven base. A full 850-gallon tank concentrates roughly 7,089 pounds on a 16-square-foot footprint, and polyethylene needs continuous, level, full-bottom support to avoid stress at the knuckle. Pour or verify a proper pad before delivery rather than after. Our guide on concrete pad sizing for above-ground polyethylene tanks lays out the ACI 360R-10 framework for getting that base right. Where this tank serves rural or remote water supply and fire-reserve duty, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. If you are aggregating grey-water, rainwater, or HVAC condensate, the industrial water reuse topology guide shows where a banded-storage tank fits the train.
How it ships
This black vertical tank ships LTL freight, quoted live to your ZIP code. Because Chem-Tainer produces from more than one plant, your order routes from the nearest of two ship points, Marked Tree, Arkansas or Merced, California, which usually shortens the lane and trims the freight bill on a tank this size. For an exact number to your delivery address, run the Freight Cost Estimator or call 866-418-1777.
