The Snyder Industries 12500 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank is a natural white crosslinked polyethylene vertical storage tank built for high-volume water storage where a rigid, impact-resistant wall matters. It stands 198 inches tall on a 142 by 142 inch footprint, and its crosslinked linear polyethylene wall carries a 1.9 specific gravity rating - meaning it is rated to hold contents substantially denser than water. For plain water at full 12,500 gallons, the load on your pad is roughly 104,250 pounds; at the tank's maximum rated contents the load reaches about 198,075 pounds. Those two numbers, not just the gallon figure, are what your foundation has to be designed around.
Will it work for your site
This is a large-diameter vertical tank, so the first thing to confirm is the pad. A 142-inch square footprint carrying up to ~198,000 pounds needs a properly engineered, level slab - our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks. To confirm the tank matches your draw and refill schedule, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide. It comes fitted per the technical drawing on this page, which shows a flange and flat fitting, an 18-inch PE threaded and vented fitting, a 12 by 30 inch fitting, a bulkhead, and a manway with a 15-inch access opening - that manway is your entry point for cleaning and interior inspection on a tank this size, so plan around it. The flange and bulkhead seal on gaskets, so verify each outlet's size, thread, and gasket material against your plumbing before install rather than assuming standard placement.
Why crosslinked polyethylene at 1.9 SG
The XLPE (crosslinked) wall is the reason to choose this vertical storage tank over a standard HDPE unit - crosslinking gives greater environmental stress-crack resistance and impact toughness, which is why Snyder rates it to the 1.9 specific gravity heavy-duty class. Be honest with yourself about that rating: if you are storing plain water, most of that 1.9 headroom is toughness you are paying for, and a lighter-duty 1.5 SG tank is the alternative. Choose the 1.9 heavy-duty class when you are storing denser contents or want the maximum wall durability for demanding service. Our write-up on Snyder XLPE vs HDPE covers when crosslinking earns its keep. For fire-water reservoir and rural fire-protection storage, the NFPA 22 sizing discipline guide shows how a tank this size fits the private fire-protection stack.
Mistake to avoid
The common error on a heavy-duty vertical this size is under-building the foundation to the water weight instead of the rated contents weight. If you store anything heavier than water, size the slab and any anchoring to the ~198,075 pound rated figure, and account for usable volume versus freeboard - our ASTM D1998 freeboard sizing guide shows how much of the 12,500 gallons you can actually put to work. Finally, keep the 18-inch vented fitting clear so the tank breathes as it fills and drains - a blocked vent on a tank this large can collapse or balloon the wall.
