The Snyder Industries 10500 Gallon Black Heavy Duty Vertical Storage Tank is built for large-volume bulk water storage where one big footprint beats a field of small tanks. It holds 10,500 gallons of water, stands 177 inches tall on a 143 x 143 inch base, and carries a 1.9 specific gravity rating - which means the tank wall is rated to hold contents up to 1.9 times the weight of water, not just water alone. Molded from heavy-wall polyethylene in black to limit light transmission and slow algae growth, it is the heavy-duty vertical storage tank operators reach for when they need serious capacity in a single vessel.

Will it work for my site?
Start with the loads. Filled with water, this tank weighs roughly 87,570 pounds; at its full 1.9 SG rating the contents can reach about 166,383 pounds. Numbers that size make the pad the real project. Above-ground polyethylene tanks of this scale need a properly engineered foundation, so read our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide before you pour. The 143 x 143 inch footprint and 177 inch height also need to clear overhead lines, eaves, and fill-access equipment. One more sizing point worth catching early: nameplate gallons are not all draw-down usable once you account for outlet height and freeboard - our freeboard sizing guide walks through the real volume you can actually use, and the Tank Sizing Calculator and Tank Sizing Guide help you size for usable volume, not just nameplate.
Common applications and fittings
A 10,500 gallon black vertical tank is a workhorse for rural fire-water reserves, bulk water, and water reuse storage. For private fire protection, capacity and draw-down have to be sized to the standard, not guessed - see our Fire-Water Reservoir Tank Design guide for NFPA 22 sizing discipline and cold-climate freeze protection. If you are aggregating grey-water, rainwater, or HVAC condensate, our Industrial Water Reuse Tank Topology guide walks through quality-banded storage trains. Inlet, outlet, vent, and manway sizes are not published in this listing spec, so confirm the bulkhead and plumbing connection sizes against the technical drawing on this page before you order gaskets, bulkhead fittings, or flex connectors.
The mistake to avoid
The 1.9 specific gravity rating is the spec people misread. It does not mean you should fill this water tank to 166,383 pounds in everyday service - it is the wall's structural rating, the headroom that makes this the heavy-duty build for demanding water duty. Size your pad and your inlet/outlet plumbing to the contents you actually store, and confirm fitting placement against the drawing before you set the tank. Getting the foundation and freeboard right up front is far cheaper than discovering a settling problem under 80,000-plus pounds of water.
This black vertical storage tank ships LTL freight from the Snyder plant in Chowchilla, CA, with the rate quoted live to your ZIP. Because it leaves a single California plant, transit distance drives the quote - West Coast ZIPs will land very differently from far-East ones - so get your real number from the Freight Cost Estimator or call us at 866-418-1777. A tank this size moves on a flatbed and needs unloading equipment on site, so plan your delivery access before it leaves the line.
