The Snyder Industries 70 Gallon Vertical Liquid Storage Tank is a white HDPE vertical tank designed to ASTM D1998 sizing logic for above-ground water and liquid storage. It stands 41 inches tall on a 23-by-23-inch footprint, and that 23-inch width clears a standard 24-to-32-inch interior door opening, so it fits into well houses, equipment rooms, pump sheds, and trailer corners where a wider vertical tank would not. This is a Snyder vertical storage tank rated to a 1.9 specific gravity, which means the shell itself is built for liquids considerably heavier than water.
Will this tank work for your job?
Filled with water, the contents weigh about 584 pounds, and the tank is structurally rated to hold contents up to roughly 1,109 pounds at its 1.9 specific gravity ceiling. Use the Tank Sizing Calculator to confirm the 70-gallon capacity against your daily draw, and the Tank Sizing Guide if you are choosing between vertical sizes. That 1.9 rating gives you real headroom: a tank engineered for 1.9 specific gravity carries plain water with margin to spare. It is also why the same shell handles heavier-than-water solutions, so if you are storing a denser liquid rather than water, confirm chemical compatibility for your fluid and consider this higher-SG shell over a water-only 1.0 to 1.1 specific gravity tank.
Fittings, access, and sealing
Per the technical drawing on this page, this storage tank is configured with a flange, an 8-inch polyethylene threaded and vented fitting, a 3.5-by-4.5-inch fitting, and a manway with 8-inch access. The vented threaded fitting matters on a closed vertical tank: it lets the tank breathe as liquid level rises and falls so you do not draw a vacuum on drawdown or pressurize the headspace on fill. That vent also defines the tank's limit, this is an atmospheric storage tank, not rated for pressure or for sealed and blanketed service. The 8-inch manway access lets you reach inside for inspection and cleaning. Before you plumb the install, confirm every outlet location and thread size against the drawing, and confirm the flange and manway gaskets are sized to these ports, since gasket fit at the flange and manway is the most common leak source on poly tanks.
Pad and wall considerations
A full vertical tank concentrates its load on a small footprint, so set it on a level, fully supporting base. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework, and the piece on HDPE tank wall thickness and ASTM D1998 sizing logic explains where vertical tanks are actually thinnest and how to inspect them. If this tank is headed for rural fire-water duty, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
