The Snyder Industries 300 Gallon Vertical Liquid Storage Tank is a white HDPE vertical tank built for water and general liquid storage where you need a tall, small-footprint vessel. It stands 82 inches tall on a 36 x 36 inch base, holding 300 gallons of water that weighs about 2,502 pounds when full. The tank carries a 1.9 specific gravity rating - higher than the 1.0 to 1.5 typical of water-only tanks - so it is engineered to handle contents denser than water up to a maximum rated contents weight of 4,754 pounds, while remaining a straightforward white polyethylene storage tank.
Will it work for your site?
This vertical storage tank concentrates 300 gallons into a 36-inch square footprint rather than spreading the load wide, so plan your pad for that 82-inch standing height and confirm the 36 x 36 inch footprint fits your space, indoors or out. The published full-water weight of 2,502 pounds is the number to use when you size the slab or stand; if you are storing a heavier liquid, work toward the 4,754-pound max rated contents figure instead. If you are unsure which size matches your draw-down and refill cycle, run the numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a height. Because the 1.9 SG rating is already built in, you are not paying to re-buy this tank if your service fluid gets denser later.
Fittings and what to verify
The technical drawing on this page shows a flange fitting and a 10-inch polyethylene fill cap. Use that drawing to confirm fitting placement and the height at which the flange exits the wall before you plumb the tank, since outlet location drives how you connect your supply and draw lines. On a tank rated for denser liquids, the flange gasket is the wear-and-compatibility item: it sits under the static head of up to 4,754 pounds of contents and is one of the real chemical-contact points alongside the polyethylene fill cap, not the HDPE shell. Confirm the flange gasket material and the fill cap are compatible with your liquid, and for HDPE wall behavior over the long term the guide on HDPE tank wall thickness and ASTM D1998 sizing logic is worth reading. This tank also works well as a fire-water reservoir; the NFPA 22 fire-water reservoir design guide covers sizing discipline and cold-climate freeze protection for that use.
The mistake to avoid
The most common error on a tall vertical tank like this is treating the 1.9 specific gravity rating as a blanket approval for any liquid. The rating tells you the tank can structurally carry weight up to 4,754 pounds of contents; it does not tell you the polyethylene, the flange gasket, or the fill cap are compatible with a given chemical. Confirm chemical compatibility separately at every contact point, and never assume the rating substitutes for a resin-and-gasket compatibility check.
