The Snyder Industries 300 Gallon Black Heavy Duty Vertical Storage Tank is a polyethylene vertical built for serious bulk water storage on a compact footprint. It holds 300 gallons in a 35-inch-diameter, 80-inch-tall cylinder, so it stands up rather than spreading out - useful when floor or pad space is tight but headroom is available. The black exterior blocks light to discourage algae growth in stored water, and the heavy-duty wall construction carries a 1.9 specific gravity rating, meaning the tank shell is built to handle contents considerably denser than water.
Will this 300 gallon vertical storage tank work for you?
Start with weight, because that is what catches most buyers off guard. Filled with water, this 300-gallon vertical tank carries about 2,502 pounds of contents. At its full 1.9 specific gravity rating, the maximum rated contents weight climbs to roughly 4,754 pounds. That load has to land on a flat, fully supporting surface - a level concrete pad or an engineered base, never bare soil or a few sleepers. The footprint is 35.0 x 35.0 inches, so size your pad to support the full diameter, not just the center. One caveat on a tall cylinder like this: the 300 gallons is nominal, and your usable volume depends on outlet height and draw-down - run your real numbers through our Tank Sizing Calculator and review the Tank Sizing Guide so you size for usable capacity, not just the number on the label.
Setting it on the right base
Because all 2,502-plus pounds of a full tank press down through a 35-inch circle, pad design matters as much as tank selection. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab supports the load without cracking or settling. For cold-climate sites, freeze protection and the role of a polyethylene reservoir in a private fire-protection stack are covered in our fire-water reservoir design guide. Planning grey-water, rainwater, or HVAC condensate aggregation? Our industrial water reuse tank topology guide shows how a single vertical storage tank fits into a quality-banded storage train.
The mistake to avoid
The common error with a vertical tank this tall is treating it like a short, wide tank. At 80 inches tall on a 35-inch base, this is a relatively narrow, high-standing cylinder, so it must be sited where it cannot be bumped, tipped, or left unsecured against wind on an empty day. Empty, the tank is light and top-heavy until filled - set it in place, plumb it level, and connect plumbing before you fill, not after. Fitting size and placement are not something to assume - confirm them against the technical drawing on this page, or call before you plumb. And do not let the 1.9 specific gravity rating talk you into chemical service: this is configured for water storage, so any non-water use has to clear two separate checks first - chemical-to-resin compatibility for the polyethylene shell, and elastomer compatibility for every gasket and fitting that touches the fluid.
