The Snyder Industries 330 Gallon HDPE Vertical Liquid Storage Tank is a 50-inch-tall white polyethylene tank built on a 47 x 47-inch square footprint, rated to a 1.9 specific gravity. It holds 330 gallons of water or other liquids and is the kind of vertical storage tank operators reach for when they need real capacity without a sprawling pad. This page covers what it handles, how it ships LTL from California, and the one sizing detail worth getting right before you order.
What this HDPE storage tank handles
Filled with water, the contents weigh about 2,752 pounds, and the tank wall is rated to carry up to 5,229 pounds of contents at its 1.9 specific gravity ceiling. That 1.9 rating is generous for a vertical HDPE tank: it covers liquids up to roughly 15.8 pounds per gallon, which puts most fertilizers, brines, and denser process liquids within reach rather than just plain water. So if you are buying for water today but might store a heavier liquid down the road, this tank gives you that headroom instead of forcing a second purchase. Match the stored fluid to the right gasket and fitting material before you commit, and confirm the outlet and lid configuration on order by calling 866-418-1777, since fitting layout is set per tank. The square 47 x 47-inch footprint keeps the center of gravity tight for a 50-inch tank.
Sizing and pad notes
A loaded tank in the 2,700-plus-pound range puts real point load on whatever it sits on, so the pad matters as much as the tank. If you are still deciding between sizes, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you pour anything. For above-ground polyethylene tanks, our guide on concrete pad sizing within the ACI 360R-10 framework walks through getting the base right. If you are sizing for fire-water reserve on a rural or remote site, the NFPA 22 reservoir sizing discipline guide covers freeze protection and how a polyethylene tank fits the private fire-protection stack. For the engineering behind the wall itself, our piece on HDPE wall thickness and ASTM D1998 sizing logic explains why the headspace, not the liquid side, is where premature failures tend to start.
The mistake to avoid
The biggest error on a tank like this is treating the footprint as the only sizing constraint. The 47 x 47-inch base is compact, but a 50-inch-tall tank carrying nearly 2,800 pounds of water needs a level, fully supported pad under the entire base. Pour the slab and verify it is flat before the tank arrives, not after. See the technical drawing on this page for the overall dimensions and outlet locations so you can rough in plumbing before delivery.
This vertical storage tank ships LTL from the Snyder Industries plant in Chowchilla, California, so if you are east of the Rockies, freight is a real line item worth pricing before checkout rather than after.
