The Snyder Industries 1200 Gallon Vertical Liquid Storage Tank is a white HDPE vertical storage tank standing 109 inches tall on a 60 x 60 inch footprint, holding 1,200 gallons. It carries a 1.5 specific gravity rating, which means the wall is engineered to hold contents up to 50 percent denser than water at full volume. Filled with water, the tank holds 10,008 pounds; at its full 1.5 SG rating it is built to carry up to 15,012 pounds of contents. That weight, not the gallon number, is what governs your pad and your placement.
Will it work for your site?
This is a vertical storage tank with a 60 inch diameter base and a 109 inch overall height, so plan vertical clearance and a fill route before delivery. The technical drawing on this page shows three points of access and connection: a flange, an 18 inch PE threaded and vented fitting, and a manway with a 15 inch clear access opening for interior reach during cleaning and inspection. That 15 inch access is your cleanout and inspection port dimension, so check it against the tooling you intend to put inside the tank. Confirm the exact fitting positions and elevations against the drawing before you commit to a plumbing layout, and verify the 18 inch PE threaded/vented thread form and the flange bolt pattern against your mating hardware. Specify gaskets rated for your service liquid and the 1.5 SG load before you plumb anything. The 1.5 SG rating gives real margin for water service and for moderately heavier liquids, which makes this size a workable choice for a rural or remote fire-water reservoir as well; if that is your application, read our guide on fire-water reservoir tank design and NFPA 22 sizing. To size this against your actual draw and refill rate, run the numbers in our Tank Sizing Calculator and read the Tank Sizing Guide.
Foundation and usable volume
A loaded vertical tank concentrates its full weight onto a small 60 x 60 inch footprint, so the pad has to carry up to 15,012 pounds without settling or cracking. Pour and cure a level, full-bearing pad before the tank arrives. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and where the ACI 318 boundary applies. Note that the 1,200 gallon figure is the nominal capacity, not the volume you should fill at higher density: as your service density approaches the 1.5 SG ceiling, design to less than 1,200 gallons and size freeboard per ASTM D1998 so thermal expansion does not overtop the tank. The Snyder Captor double-wall freeboard guide walks through that math, and if you need secondary containment for a heavier liquid it points to the double-wall path. For operators who want to understand where these tanks actually wear over time, the breakdown of HDPE wall thickness at the vapor-saturated headspace explains the ASTM D1998 sizing logic relevant to tanks like this one.
The mistake to avoid
The most common error on a tank this size is treating the gallon figure as the load. It is not. Design your foundation and any anchoring to the full contents weight at your service density, up to the 15,012 pound ceiling this tank is rated for, not to 1,200 gallons of "water." Second, do not assume the 18 inch threaded fitting and the manway are interchangeable connection points; size your fill, vent, and access plumbing to the specific fittings shown on the drawing, with gaskets and thread forms matched to your hardware.
