The Snyder Industries 330 Gallon Vertical Water Storage Tank in green is a polyethylene vertical water tank built for above-ground bulk water storage, with a 47-inch round footprint and a 50-inch height that fits under most eaves. It carries a 1.0 specific gravity rating, the right match for water and other fluids no heavier than water at full fill.
Will it work for your install?
This vertical storage tank holds 330 gallons in a 47.0 x 47.0 inch footprint. Filled to capacity with water, it carries 2,752 pounds of contents, which is also its maximum rated contents weight at the 1.0 specific gravity rating. Plan your pad and tie-downs around that full-water figure, not the empty shell. Access matters too: the 47-inch round footprint clears a standard double-gate or driveway opening but will not pass a single 36-inch pedestrian gate, so verify your delivery access width before it arrives. The tank ships with an 18-inch polyethylene manway whose integral 4-inch vent equalizes pressure during both fill and draw-down (so the wall does not collapse on a fast pump-out) and whose molded tie-down anchors the lid (ASM MANWAY 18IN PE W/4IN VENT W/TIE SII). It also carries a molded-in flange, a 2-inch polypropylene bulkhead fitting with EPDM gasket that suits the primary fill, draw, or pump-suction port, and a 1-1/2-inch polypropylene bulkhead with EPDM gasket for a secondary, overflow, or recirculation line. Fitting sizes, port locations, and overall dimensions are all called out on the technical drawing on this page, so confirm your plumbing and overflow routing against it before you order.
Sizing and siting the tank
At 2,752 pounds full, this water storage tank needs a flat, fully supporting base that carries the entire bottom, not a ring or a few blocks. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm the 330-gallon capacity and the 47-inch footprint suit your site. If you are pouring a slab, the concrete pad sizing framework for above-ground polyethylene tanks walks through the load math, and after install the hydrostatic test methodology covers the water-fill acceptance and fitting leak check that catches problems before the tank goes into service.
The mistake to avoid
The 1.0 specific gravity rating is the line not to cross. Both halves of this tank are matched to water service: the polyethylene wall is rated for water and fluids at or below the density of water, and every wetted seal here is an EPDM bulkhead gasket, well suited to water and dilute aqueous solutions. Storing anything heavier per gallon, such as many liquid fertilizers or chemical concentrates, exceeds the wall rating and is the wrong choice for this green water tank. If you need to store a denser or chemically aggressive fluid, do not force it into a water tank: use the Tank Sizing Guide or call 866-418-1777 and we will match you to a tank rated for that service. For rural fire reserve or reuse-train duty where this size often lands, the fire-water reservoir design guide and the industrial water reuse tank topology guide show where a vertical storage tank this size fits the system.
