The Snyder Industries 330 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 330-gallon vertical storage tank molded from polyethylene, built to the ASTM standard and rated to a 1.9 specific gravity. That heavy-duty rating is why this tank earns a first look for demanding bulk water work: at 55 inches tall on a 48 x 48 inch footprint, the shell is structurally engineered with real headroom over a standard 1.0 or 1.5 SG water tank of the same size, so it carries its full loaded weight with margin to spare in bulk water storage, irrigation supply, and rainwater or reuse holding.
Will it work for your site?
Plan around three numbers. Filled with plain water, this tank holds about 2,752 pounds of contents; the 1.9 SG structural rating means the shell is engineered to carry up to roughly 5,229 pounds of contents at full capacity. The 48 x 48 inch footprint sets the pad or ring you need, and the 55 inch height sets your fill-access and overhead clearance. This tank ships from Chowchilla, California, so West Coast sites will see the shortest LTL lanes when you weigh freight against the loaded weight. If you are matching this tank to a specific volume or a fire-water reserve, run your target through the Tank Sizing Calculator and the Tank Sizing Guide before you commit. For above-ground installs, the pad matters as much as the tank: see our guide on concrete pad sizing for above-ground polyethylene tanks so the base is rated for the loaded weight.
Fittings and configuration
Fitting and outlet configuration is not specified in this listing. Verify port placement against the technical drawing on this page, or call 866-418-1777 before you plumb the tank for fill, draw, and overflow. The Black shell blocks light transmission, which limits algae growth in outdoor water service. If you are designing a rural or remote fire-water reservoir, our guide on fire-water reservoir tank design walks through NFPA 22 sizing discipline and freeze protection for cold-climate service. For grey-water, rainwater, and HVAC condensate aggregation, the industrial water reuse tank topology guide covers how to band and sequence storage.
The mistake to avoid
Do not under-spec the pad or the plumbing relative to the loaded weight. It is easy to size the base for a water fill and forget that this shell is rated to nearly double that in contents weight at 1.9 SG. Build the pad and support the outlet plumbing for the full 5,229 pound rated load, not the 2,752 pound water number, and you will not chase cracks or sagging fittings later.
