The Snyder Industries SII-32455 is an 8,000 gallon vertical liquid storage tank molded in white High Density Linear Polyethylene, standing 183 inches tall on a 120 x 120 inch footprint. It carries a 1.5 specific gravity rating, so it holds denser liquids that a standard 1.0-rated tank of the same volume cannot. For any operation sizing bulk white water storage, this vertical storage tank puts a large working volume onto a compact square footprint, and every planning number you need is on this page or in the technical drawing.
Will it work for your storage plan
Full of water, the tank holds roughly 66,720 pounds of contents, and its 1.5 SG rating allows a maximum rated contents weight near 100,080 pounds. That headroom is the reason to check specific gravity before you fill: plain water and most fresh-water applications sit at 1.0 and are well inside the envelope, while denser liquids climb toward the 1.5 ceiling. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm your fill volume and standing weight before you pour a pad. The 120 x 120 inch footprint needs a level, engineered foundation rated for the full loaded weight; a slab that carries a smaller vertical tank will not hold an 8,000 gallon column.
Fittings and outlets
This tank is configured with an 8" x 7" flat fitting, a 3-inch polypropylene bulkhead fitting with an EPDM gasket, and a 20-inch vented manway up top for access and venting. Stainless steel lid hardware secures the lid band. The bulkhead seal is EPDM, so verify EPDM is compatible with your stored liquid before filling; it is fine for water and most fresh-water service. Confirm the 20-inch manway's vent capacity matches your maximum fill and discharge rate, and check outlet size, location, and elevation against the technical drawing on this page before you set the tank, since bulkhead placement drives where your suction and fill lines land and how you plan pad penetrations.
Freight and how it ships
This Snyder vertical storage tank ships by LTL freight from Snyder's Merced, CA plant, so West Coast buyers get a short lane and buyers farther east should plan for a longer haul. At 183 inches tall it moves as an oversized load, so freight is quoted live to your ZIP rather than listed as a flat number. Get your number from the Freight Cost Estimator, and if you are planning a fire-water reservoir or a rural bulk-water install, the fire-water reservoir design guide walks through sizing discipline and cold-climate protection for tanks this size.
