The Snyder Industries 1100 Gallon HDPE Vertical Liquid Storage Tank is a 1.9-specific-gravity-rated vessel built for heavier-than-water liquids, and it answers the three questions that matter before you buy: will it hold your liquid, what will freight run, and what mistake will cost you. This is a vertical storage tank on an 86 x 86 inch footprint, standing 55 inches tall, molded in white High Density Linear Polyethylene and carrying an ASTM certification. That is a low, wide profile for a vertical tank, which makes it stable but means you need a clear pad of at least 86 x 86 inches before delivery. Filled with plain water it weighs roughly 9,174 lb; at its full 1.9 SG rating it can carry up to 17,431 lb of contents, so your pad and anchoring need to be sized for the heavier number, not the water number.
Will it work for your liquid
The 1.9 specific gravity rating is the differentiator on this SKU. Standard vertical water tanks are rated to roughly 1.0 to 1.5 SG; this Snyder tank's 1.9 rating means it is engineered for dense liquids well above water weight, covering brines and similar heavy solutions where a water-rated tank would be under-spec. That is why the max rated contents weight reaches 17,431 lb on the same volume. If your liquid is lighter, you have margin to spare. If you are unsure how the volume maps to your actual fill level, run the numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a footprint.
Fittings and access
Per the technical drawing on this page, this Snyder vertical tank comes configured with a flange, a 9" x 9" flat fitting, an 18" polyethylene threaded and vented fitting, an additional flat fitting, and a manway with 15" access. The flange and the two flat fittings are flat landings that need a matching gasket and bolt-up flange kit to seal, the 18" threaded and vented fitting serves as your vent and lid, and the manway with 15" access is your inspection and cleanout point. Match your gasket material and bulkhead fitting sizes to those exact landings off the drawing before you order plumbing, since the fill, draw, and vent lines all land on them. See the technical drawing on this page for exact placement.
The mistake to avoid
The common error on a tank rated this high is anchoring and foundation built for water weight. At full rating this tank loads its pad with over 17,000 lb of contents, nearly double the plain-water figure. Spread across the 86 x 86 inch footprint (about 51 square feet) that works out to roughly 340 lb per square foot of contents loading, a number your slab and any engineer should check the bearing capacity against. Size your slab, hold-downs, and any seismic or wind anchoring to the 1.9 SG max rated contents weight, and verify your liquid's specific gravity against that 1.9 ceiling rather than assuming a water-equivalent load.
