The Snyder Industries 16,500 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a large-format polyethylene vertical storage tank built for high-volume water service, standing 257 inches tall on a 142-inch diameter footprint. It carries a 1.9 specific gravity rating, so the wall is engineered with a wide safety margin for bulk water and is not wall-limited for this service. If you are comparing vertical tank options for a fire-water reservoir, bulk water holding, or an industrial water reuse train, this is one of the heavier-duty vertical bodies in its class.
Will it work for your site?
Filled with water this vertical storage tank holds roughly 137,610 pounds of contents, well inside its 1.9 SG rated ceiling of about 261,459 pounds. That headroom is safety margin for water, not an invitation to run a denser fill. The 142-inch diameter is the footprint you plan concrete, setback, and site clearance around. Interior entry and cleanout are through the manway with 15-inch access, and every inlet, outlet, and overflow tie-in has to land on the ports the tank already carries: the flange, the 12" x 26" fitting, the 18" PE threaded/vented fitting, and the flat fitting shown on the technical drawing on this page. That 18" PE threaded/vented fitting is your atmospheric vent, and a tank this size must vent freely on fill and draw, so treat it as a designed feature and gasket every penetration to its specific port. Confirm the full fitting layout against your plumbing plan before ordering, since large vertical tanks are difficult to re-plumb once set.
Sizing and foundation
For a body this large, get the pad right first. Our Tank Sizing Calculator and Tank Sizing Guide help you match capacity to draw-down needs, and our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework for a level, load-rated base. If this is a rural or remote fire-water reservoir, the NFPA 22 sizing discipline for fire-water reservoirs covers the sizing and freeze-protection details operators miss.
The mistake to avoid
The most common error on a tank this large is designing the foundation to the empty shell or to a partial fill. Build the pad and any anchoring to the loaded water weight of roughly 137,610 pounds with margin. Under-building the base is the failure operators regret most. It is also worth reviewing where HDPE wall thickness and premature failures originate so your inspection routine covers the vapor-saturated headspace, not just the liquid side.
This vertical storage tank ships LTL freight from the Snyder plant in Lincoln, Nebraska, quoted live to your ZIP. At over 21 feet tall and nearly 12 feet wide, it routes as an oversize load, so plan offload clearance and site access in advance.
