The Snyder Industries 70 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a compact vertical storage tank molded from high density linear polyethylene and rated to a 1.9 specific gravity - a heavy-duty wall rating that gives you real headroom over plain water. It stands 41 inches tall on a tight 23 x 23 inch square footprint, so it fits through most doorways and tucks into corners, utility rooms, and equipment skids where floor space is the constraint. If you are weighing capacity against your available space, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit.
Will it work for your setup?
At 70 gallons, filled with water this tank carries about 584 pounds; at its full 1.9 specific gravity rating the contents can reach roughly 1,109 pounds, so size your pad, stand, or platform for the heavier figure rather than water alone. The black exterior blocks light, which helps discourage algae growth in stored water. The connection interface, shown on the technical drawing on this page, is straightforward - manway access is 8 inches for cleanout and inspection, and there is an 8" polyethylene threaded and vented port, a molded flange, and a 3.5" x 4.5" fitting (see the drawing for its role and location). That is enough plumbing to feed, vent, and service the tank without cutting your own penetrations. Review the drawing to confirm the fitting locations line up with your inlet and outlet runs.
The mistake to avoid
Do not size the support structure to water weight. This is a 1.9 specific gravity tank, meaning the wall is rated for dense contents, and if you ever store a fluid heavier than water the loaded weight climbs toward that 1,109 pound figure. Two things to separate: 1.9 is the fluid-density ceiling, so any liquid up to that specific gravity is within the tank's structural rating - but chemical compatibility of the resin, gaskets, and fitting materials is a separate check from density. Also remember that the manway lid, flange, and threaded port each seal on their own gasket, and that gasket material must be matched to the stored fluid before service. Build the base for the rated load, keep it level, and support it continuously across the whole 23 x 23 inch footprint - never set a full vertical tank on point contacts or an unlevel surface. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the framework.
