The Snyder Industries 130 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 130-gallon vertical storage tank molded in black polyethylene, standing 49 inches tall on a compact 29 x 29-inch square footprint. It carries a 1.9 specific gravity rating, which is the number that tells you how heavy a liquid this tank is built to hold. That rating is the real reason to look closely before you buy, so start there rather than with the gallon number alone.
Will this tank work for what I'm storing?
For water storage, this tank is straightforward. At 130 gallons, a full load of water weighs about 1,084 pounds, and the tank is rated to carry contents up to roughly 2,060 pounds. Those two numbers are worth writing down for pad design: 1,084 lb is your everyday water load, and 2,060 lb is the ceiling the 1.9 specific gravity rating buys you. If you are storing anything denser than water, that headroom matters — a liquid at 1.9 specific gravity is nearly twice the weight of water per gallon, and this tank is built to carry that heavier load where a standard 1.0-rated tank would not be. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the volume you actually need before committing to a footprint. Because this is an ASTM D1998 Snyder tank, the Snyder freeboard sizing guide is a good read on how thermal expansion and density set the volume you can actually use.
Fittings, access, and dimensions
The full envelope is 49 inches tall by 29 inches wide by 29 inches deep — check that against your door, ceiling, and truck clearance before the freight ships. Per the technical drawing on this page, this vertical tank is configured with a flange, a separate 8-inch polyethylene threaded and vented fitting, and a manway with an 8-inch access opening on top. Note those are two distinct 8-inch features: the vented fitting and the manway access, not one shared opening. The vented fitting matters — any tank that fills or drains needs to breathe, or you risk pulling a vacuum and deforming the tank. The 8-inch manway gives you a practical opening for cleaning and inspection. Confirm the fitting layout against the drawing for your specific plumbing before you set the tank on its pad.
The mistake to avoid
The most common error on a heavy-duty vertical tank like this is undersizing the pad and support. With a filled weight approaching a ton on a 29 x 29-inch base, this tank concentrates real load on a small area. It needs a level, fully supporting foundation — the whole footprint bearing evenly, not spanning a gap or perched on uneven ground. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the framework for getting that base right. If the tank is part of a grey-water, rainwater, or condensate system, our industrial water-reuse tank topology guide covers how to band storage by quality.
