The Snyder Industries 850 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a high-capacity vertical tank molded from high density linear polyethylene, standing 117 inches tall on a 48 by 48 inch square footprint. Rated for 850 gallons and carrying a 1.9 specific gravity rating, this black tank is built to hold contents heavier than water, which makes it a durable choice for demanding vertical storage where a standard water-weight tank would fall short.
Will this tank work for your job?
Filled with water, the contents weigh roughly 7,089 pounds; the tank is rated to carry contents up to 13,469 pounds at its full 1.9 specific gravity rating. That headroom is the reason to choose this model, since it accommodates fluids denser than water without exceeding the wall's design limits. Note the resin is high density linear (not cross-linked) polyethylene, a distinction worth weighing when you check fluid and gasket compatibility at the top of the 1.9 band. To match capacity to your draw-down and refill cycle, run the numbers with our Tank Sizing Calculator or walk through our Tank Sizing Guide. Because it is a vertical storage tank, the tall 117-inch profile keeps the ground footprint compact where space is tight.
Siting, pad, and freight planning
A full vertical tank this size concentrates thousands of pounds over a small 48 by 48 inch area, so the foundation matters. A level, continuously supported pad is what keeps the shell from stressing at the base. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for sizing that pad correctly, and for cold-climate installs the fire-water reservoir design guide covers freeze-protection engineering that applies to any stored-water reservoir. Snyder molds this tank at plants in Lincoln, NE, Marked Tree, AR, and Philippi, WV, so confirm the pad and access are ready for the plant nearest your delivery address.
The mistake to avoid
The 1.9 specific gravity rating is a maximum, not an invitation to skip the math. If you are storing a fluid heavier than water, verify its specific gravity against that 1.9 ceiling before filling. Just as important: fitting and outlet configuration is not specified for this listing, so do not assume a pre-plumbed tank. Confirm the outlet, bulkhead size, and gasket material you need are available on this configuration with us at 866-418-1777 before ordering, and match those parts to your actual service. If your stored volume grows or freeboard for thermal expansion becomes a factor, our write-up on freeboard sizing per ASTM D1998 explains the usable-volume difference.
