Snyder Industries 1100 Gallon ASTM Black Heavy Duty Vertical Storage Tank

The Snyder Industries 1100 Gallon ASTM Black Heavy Duty vertical storage tank is a molded polyethylene vertical tank built for demanding bulk water and liquid storage.It holds a rated 1,100 gallons on a wide, low-profile stance — 86 inches in diameter and only 55 inches tall, which makes it wider than it is tall.That squat geometry is deliberate: it clears low-ceiling buildings, covered structures, and enclosures where a conventional tall vertical tank won't fit.The black resin cuts light transmission to slow algae growth in stored water, which is why it shows up in searches for a black vertical storage tank on outdoor and agricultural sites.

Will it work for your site?

Sizing is where this tank earns its keep.Filled with plain water it carries roughly 9,174 lb of contents, and the wall is rated to hold up to 17,431 lb at its 1.9 specific gravity limit.That 1.9 SG rating is well above the 1.9 SG of water — for a water buyer it means an over-built wall and longer service life, and for anyone storing heavier ag or industrial liquids it means real capability in reserve.Either way, plan your pad for the full loaded weight, not the empty shell.Run the numbers with our Tank Sizing Calculator and Tank Sizing Guide to confirm the volume matches your draw-down and refill cycle before you order.

Fittings and access

Per the technical drawing on this page, the tank is configured with a flange, an 18-inch PE threaded/vented fitting, a manway with a 15-inch access opening, and a 15 x 15 fitting.There is also a molded flat pad for a field-added bulkhead or outlet — a flat location you drill and plumb where you need it, not a pre-cut hole.The 15-inch manway makes interior inspection and cleanout practical.Confirm the exact thread sizes, gasket spec, and outlet locations against the drawing for your plumbing before you set the tank on its pad.

Foundation and next step up

A vertical tank this heavy needs a flat, fully supporting base.Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework.If your application calls for secondary containment beyond a single-wall tank, see our guide on Snyder Captor double-wall freeboard sizing.For rural fire-water reservoir or water-reuse duty, our fire-water reservoir sizing and industrial water-reuse topology guides go deeper.
