The Snyder Industries 300 Gallon Vertical Storage Tank is a black crosslinked polyethylene (XLPE) tank built for heavy-duty water and dense-liquid storage where a tall, compact footprint matters. It stands 82 inches high on a 36 x 36 inch base, holds 300 gallons, and carries an ASTM XLPE build rated to a 1.9 specific gravity. That rating is the headline spec: the wall is engineered to hold contents up to 1.9 times the density of water, which is why the maximum rated contents weight reaches 4,754 lb even though 300 gallons of plain water weighs about 2,502 lb. On a straight water duty, that margin is money in the bank for a long service life.
Will it work for your site?
The 36 x 36 inch footprint makes this a strong pick where floor space is tight but vertical clearance is available, so confirm you have at least 82 inches of overhead plus room to reach the top fill. On fittings, this vertical storage tank comes with a top 10-inch polyethylene fill cap and a flange fitting; no bottom drain outlet is listed on the technical drawing on this page. If your plumbing plan assumes a bottom bulkhead or a specific outlet size, check the drawing against your layout before you order, because the molded fitting positions are fixed. To confirm the 300 gallon size against your actual demand, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide.
XLPE vs. HDPE, and the mistake to avoid
The most common misstep on a tank like this is treating XLPE and HDPE as interchangeable. Crosslinked polyethylene is a denser, more impact- and stress-crack-resistant material than standard linear HDPE, which is why Snyder rates this tank to 1.9 specific gravity rather than a lighter number. For a heavy or full-height water column, that crosslinked wall is doing real structural work, and our guide on when crosslinking matters walks through where it pays off. For fire-reserve or rural water-storage duty, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection for polyethylene tanks.
Set it on the right base
Filled with water this tank carries about 2,502 lb, and at its full 1.9 SG rating it reaches 4,754 lb of contents, pushed onto just a 36 x 36 inch footprint. That load needs full, continuous support underneath. A level concrete pad or a properly built platform is the difference between a tank that lasts decades and one that stress-cracks at the base. Our concrete pad sizing guide lays out the ACI 360R-10 framework for above-ground poly tanks.
