The Snyder Industries 330 Gallon HDPE Vertical Liquid Storage Tank is a white polyethylene tank standing 55 inches tall on a 48-inch diameter, holding 330 gallons in a compact vertical column. It is rated for liquids up to a 1.9 specific gravity and built and shipped from Snyder's Chowchilla, California plant. That high structural rating, paired with a small 48 x 48-inch footprint, makes it a workhorse for water storage and general HDPE storage tank duty where ground space is tight but liquid volume matters.
Will it work for your job
Filled with plain water, this tank carries about 2,752 pounds of contents. The reason that number matters less than it looks: Snyder rates this shell for a 1.9 specific gravity, which means the same tank legitimately handles solutions far denser than water, up to a maximum rated contents weight of 5,229 pounds at full fill. Water runs roughly 8.34 pounds per gallon, so a 330-gallon water fill sits well inside the structural envelope. If you may later store a heavier ag or industrial liquid in that 1.0 to 1.9 density band, you buy this tank once instead of re-buying a water-only shell rated to a lower specific gravity. Use the Tank Sizing Calculator and the Tank Sizing Guide to match this 330-gallon size to your real draw-down and refill cycle before you order.
Specs and what to verify
Capacity is 330 gallons; the tank stands 55 inches tall on a 48-inch diameter and a 48 x 48-inch footprint; color is white HDPE; the specific-gravity rating is 1.9. This model is built to ASTM D1998, the standard governing polyethylene upright storage tanks. Before ordering, confirm the outlet and fitting layout against the specifications shown for this model and on the technical drawing on this page, then match it to your plumbing. For how the wall behaves over the life of the tank, including the vapor-saturated headspace where premature failures tend to start, read our guide on HDPE tank wall thickness and ASTM D1998 sizing logic.
The mistake to avoid
The common error on a vertical tank this tall is skipping the pad and anchoring math. A full tank at the rated 1.9 specific gravity can land up to 5,229 pounds on the slab, and that load has to sit on properly sized, level concrete. Size the pad before the tank arrives using our guide on concrete pad sizing for above-ground polyethylene tanks. If you are spec'ing this for rural fire-water or reservoir duty, the NFPA 22 fire-water reservoir guide covers freeze protection and sizing discipline for cold-climate sites.
