The Snyder Industries 1500 Gallon Black Heavy Duty Vertical Storage Tank is a polyethylene vertical storage tank built for demanding bulk water duty, and its defining number is the 1.9 specific gravity rating. That rating is what separates this heavy-duty model from a standard 1.0 water tank: the wall is engineered to carry contents denser than water. Filled with water the tank holds roughly 12,510 lb, and it is rated to carry up to 23,769 lb of contents at its 1.9 SG limit, so you have real headroom for dense water service without pushing the tank past its design.
Will it work for your site?
The tank stands 72 inches tall on an 86 x 86 inch footprint, so plan a level pad at least that square plus working clearance around the shell. That footprint is about 51 square feet, so at the full 23,769 lb rated load the pad sees on the order of 460 lb per square foot of bearing pressure (about 245 lb/ft² with water alone) — hand that number straight to your pad design. Because a full tank is a substantial static load, the base has to be flat, continuous, and properly supported; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework with exactly this input. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm 1500 gallons matches your draw and refill cycle.

Fittings and venting
This vertical tank comes configured with a flange, a 15 inch x 15 inch fitting, a flat fitting, and a 10 inch polyethylene cap with tie. On a water install the flange is your bulkhead inlet/outlet connection — and its gasket-and-backing seal against the poly wall is the single most common leak point, so verify a compatible gasket material and even torque before you fill. The 15 x 15 fitting and the flat fitting serve as top plumbing and instrument penetrations, and the 10 inch capped port is your manway for fill and inspection access. Confirm the exact locations and sizes against the technical drawing on this page before you plumb the inlet, outlet, and overflow. As a closed-top tank, it must have a functioning atmospheric vent — sized per the linked method — before it moves liquid, or the poly wall can pull a vacuum and collapse on drawdown; our API 2000 vent-sizing examples for 1500 to 10,000 gallon verticals show how to size it correctly.
The mistake to avoid
The 1.9 SG rating is a ceiling, not a license to store anything. It means the tank can carry contents up to about 1.9 times the density of water — that is the 23,769 lb versus 12,510 lb headroom — but density headroom is not chemical-resistance clearance. This is a water-service vertical storage tank; match the contents density to that rating and keep it inside water and compatible bulk-liquid duty. Buying a standard-wall tank for dense contents, or the reverse, is the most common and most expensive sizing error on a tank this size.
This tank ships LTL freight, quoted live to your ZIP. It can originate from either the Lincoln, NE or Philippi, WV plant, and the shipping origin depends on current stock rather than geography alone, so run the numbers instead of assuming the closer plant.
