The Snyder Industries 12500 Gallon Black Heavy Duty Vertical Storage Tank (SKU 5350000C34, polyethylene, Black) is built for large-volume bulk water storage where a single tank has to hold serious head pressure without flexing or failing. At 198 inches tall (16.5 ft) on a 142 x 142 inch footprint (roughly 11.8 ft across), this is a full-scale vertical storage tank that needs about 17 feet of vertical clearance before you account for pad height. The heavy-duty wall construction carries a 1.9 specific gravity rating, which is well above the 1.0 of plain water. That rating margin is what earns the "heavy duty" name: the wall is engineered for contents up to 1.9 specific gravity, so on plain water this tank runs at roughly 53% of its rated load.
Will this tank work for your site?
Run the weight numbers before you pour anything. Filled with water, this tank carries roughly 104,250 pounds of contents. At its maximum rated contents weight it holds up to 198,075 pounds. Those loads land on a 142 x 142 inch footprint, so your foundation has to be sized and reinforced to carry it. For a black vertical tank of this scale, a properly engineered concrete pad is not optional. Walk the numbers through our Tank Sizing Calculator and read the concrete pad sizing framework covering the ACI 360R-10 approach and the ACI 318 boundary so the slab is matched to the real loaded weight, not just the empty tank. The technical drawing on this page gives you the exact dimensions and fitting locations to lay out before the slab is poured.
Sizing it into your system
A 12,500 gallon polyethylene tank usually anchors a larger storage train rather than standing alone. If you are designing reserve capacity for rural or remote fire protection, the fire-water reservoir design guide walks through NFPA 22 sizing discipline and freeze protection for cold-climate service. For reuse and aggregation systems, the industrial water reuse topology guide covers grey-water, rainwater, and HVAC condensate aggregation into quality-banded storage trains. When you are pinning down usable volume versus freeboard, the freeboard sizing guide per ASTM D1998 covers thermal expansion and the real volume you can actually draw. Use the Tank Sizing Guide to confirm this capacity matches your draw-down and refill cycle before you commit.
The mistake to avoid
On a tank this size, the costly mistake is underbuilding the pad for the loaded weight. People size the slab to the tank and forget that nearly 200,000 pounds of rated contents is the number that actually matters. Build the foundation to the maximum rated contents weight, confirm it is dead level, and verify your fittings and outlets before the tank is filled. An out-of-level pad on a tank carrying six figures of weight puts uneven stress into the wall that no amount of heavy-duty construction is meant to absorb.
This tank ships LTL freight from the Snyder plant in Lincoln, NE, with freight quoted live to your ZIP. Because it ships standing at 16.5 feet tall, you will need a crane or large-reach forklift staged to set it, and the install site has to clear that height plus pad. Get your number through the Freight Cost Estimator or call 866-418-1777 and we will quote it for you.
