The Snyder Industries 1100 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a polyethylene vertical tank built to ASTM standards for bulk water storage that has to hold up outdoors and under load. What sets this unit apart from a standard water tank is its 1.9 specific gravity rating: where a typical 1.1 to 1.5 SG water tank is walled for water and little else, this shell is engineered to carry dense contents well beyond plain water. The black polyethylene is an engineering choice, not a cosmetic one. Black resin blocks UV and light far better than a translucent wall, which makes it the right pick for an outdoor storage tank exposed to sun and for keeping stored water dark and stable.
Will it hold up on your site?
Sizing and support come first. Filled with water, this tank carries roughly 9,174 pounds of contents; at its full 1.9 SG rating it is built for up to about 17,431 pounds of contents weight. That reserve is the buy reason, but it also sets the pad requirement: on its 86 by 86 inch footprint the tank needs a level, continuously supported base rated for the actual loaded weight you plan to store, with no gaps or point loads. Confirm overall height and clearances against the technical drawing on this page before you commit a pad location. Our Tank Sizing Calculator and Tank Sizing Guide match capacity to demand, and the concrete pad sizing guide walks the ACI framework for above-ground poly tanks. For fire-reserve duty, the NFPA-22 fire-water reservoir guide covers sizing discipline, and the water-reuse topology guide shows where a black vertical storage tank fits a grey-water or rainwater train.
Fittings and access
This vertical tank is configured with a flange, a 9 inch by 9 inch flat fitting pad, an 18 inch polyethylene threaded and vented fitting, an additional flat fitting location, and a manway with 15 inch access for interior entry, inspection, and cleaning. Treat the flat pads and the flange as your gasketed field-connection points: match the flange gasket and any bulkhead-fitting gaskets to those pads, and confirm the manway gasket seals cleanly around the 15 inch access. The 18 inch vented threaded fitting is not optional to plan around, since a sealed tank being filled or drained needs proper venting to avoid pulling a vacuum or over-pressurizing the shell. Verify every inlet, outlet, and vent location against the technical drawing on this page before you set the tank.
Freight and ordering
This 1100 gallon Snyder vertical tank ships by LTL freight from the Snyder plant in Marked Tree, Arkansas, the nearest named production point for this model. The price listed here is before freight, and freight is a real line item on a tank this size, so we quote it live to your delivery ZIP. Run your ZIP through the Freight Cost Estimator for a real number, or call 866-418-1777 and we will handle the quote and the order. The most common mistake on a heavy-duty vertical storage tank is under-sizing the pad for the loaded weight rather than the water weight, so with the 1.9 SG capacity in play, lock down the base before delivery day.
