The 12500 Gallon Plastic Vertical Liquid Storage Tank in White (SKU SII-5350000C37) is Snyder Industries' large-format vertical storage tank for bulk water and liquid storage where you need serious volume in a single footprint. It's molded in white High Density Linear Polyethylene (HDLPE) - linear, not cross-linked, PE is the standard resin for large single-wall verticals like this one - and it stands 198 inches tall on a 142 by 142 inch base. It carries a 1.5 specific gravity rating, meaning the tank wall is built to hold contents up to 1.5 times the weight of water, not just water alone.
Does it fit your site and your liquid?
At 12,500 gallons, this is one of the largest vertical tanks in the catalog, so three numbers govern your install: footprint, height, and loaded weight. The base occupies a 142.0 x 142.0 inch footprint - just under 12 feet square - and needs a full-diameter, level, engineered pad rated for the load. Filled with water, the tank and contents weigh roughly 104,250 lbs; at the tank's full 1.5 specific gravity rating, maximum rated contents weight climbs to about 156,375 lbs. Those figures drive your pad, ring wall, and foundation engineering, so hand them to whoever pours your base before you order. The 1.5 SG rating gives you real structural headroom above plain water, which is what makes this tank a fit for bulk water storage, fire-water reserves, and agricultural supply. If you are still confirming which size matches your draw-down and refill cycle, run the numbers through our Tank Sizing Calculator and cross-check the method in the Tank Sizing Guide.
Plan the delivery and offload early
A tank standing 198 inches tall - over 16 feet - is not a forklift-and-done delivery. Overhead clearance at the site, crane or heavy-equipment offload, and access for a load this size all need to be confirmed before the truck arrives, alongside your outlet and overflow plan, since outlet placement on a tank this tall determines usable draw and drain-down. Call our team at 866-418-1777 to walk through fitting size and placement and to coordinate the offload so the tank arrives ready for your system rather than reworked in the field.
Common mistake to avoid
The single most expensive error on a tank this size is under-building the foundation. A 12,500 gallon vertical tank puts over 100,000 lbs on the pad when full of water alone, and every gallon of a heavier liquid adds to that. Size your pad and ring wall for the maximum rated contents weight - not for water - and verify the ground bearing capacity underneath it. For fire-protection and rural reservoir installs, the sizing and freeze-protection discipline in our fire-water reservoir design guide is worth reading before you commit. Stepping down from this size? Our buyer's guides for the 2000 gallon, 500 gallon, and 300 gallon vertical tanks walk through the same decisions at smaller scale.
