The Snyder Industries 330 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a polyethylene vertical storage tank built for demanding above-ground water and liquid storage. Built to ASTM standards, it carries a 1.9 specific gravity rating, meaning the tank wall is structurally engineered to hold liquids denser than water. At 330 gallons in a compact 44-inch square footprint standing 58 inches tall, this black tank fits tight equipment pads, pump houses, and remote sites where floor space is limited but capacity still matters.
Will this Snyder vertical tank work for your job?
Start with the load your foundation has to carry. Filled with plain water, this tank holds roughly 2,752 pounds of contents; at its full 1.9 specific gravity rating, the maximum rated contents weight is about 5,229 pounds. Those two numbers, not just the tank's own weight, are what your pad and base must support. The 44 x 44-inch footprint and 58-inch height give you a stable, upright profile that pumps and plumbs easily, and the black polyethylene resists UV and blocks light, which discourages algae growth in stored water compared with translucent tanks. If you are still deciding on capacity, run your numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before you order.
Reading the specs and drawing before you buy
Review the technical drawing on this page to confirm the tank's outlet and connection layout suits your pad and plumbing before you commit. If you need specific fitting sizes or lid configuration confirmed for your install, call us and we will verify what is available on this model. Above-ground polyethylene tanks perform best on a smooth, fully supporting base, so size that foundation for the loaded weights above; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting it right. For cold-climate and rural fire-reserve installs, the fire-water reservoir design guide covers freeze protection and NFPA 22 sizing discipline.
The mistake to avoid
The common error with a black vertical storage tank like this is reading the 1.9 specific gravity rating as chemical approval. It is a structural rating only: it tells you how dense a liquid the wall can carry, not what that liquid may chemically do to the polyethylene or your fittings. For plain water, greywater capture, rainwater, and general non-aggressive liquid storage this tank is a strong fit; for anything beyond water, confirm compatibility first. If you are aggregating multiple water streams, the industrial water reuse tank topology guide lays out how to band and sequence quality-separated storage trains.
