The Snyder Industries 300 Gallon Vertical Water Storage Tank (SII-WG22) is a green High Density Linear Polyethylene tank built for above-ground bulk water storage where you need a tall, small-footprint reservoir. It stands 82 inches tall on a 36 x 36 inch base, holds 300 gallons, and carries a 1.0 specific gravity rating - the right tank for water and other contents at or below the density of water. If you are still confirming how much capacity your draw-down and refill cycle calls for, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you settle on a size.
Will this tank work for your install
Filled to capacity, this 300 gallon vertical storage tank carries 2,502 pounds of water. Size the pad and structural support for that full-water weight, not the empty tank weight - a concrete pad is the standard foundation for a tank this tall, and our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting it right. The 36 x 36 inch footprint keeps the floor space tight, which is why this profile fits well in pump houses, equipment rooms, and other tight installs. For inlet, outlet, and venting, the tank uses the bulkhead fittings, flange, and 10 inch polyethylene lid with tie shown on the technical drawing on this page - a 1-1/2 inch and a 2 inch port among them. Confirm every fitting location and size against that drawing before you plumb your inlet and outlet.
The mistake to avoid: don't undersize the foundation or oversize the contents
The most common error on a vertical tank this tall is treating it like a stock tank you can set on bare dirt. At 82 inches with 2,502 pounds of water up top, this tank needs a level, fully-supporting base - an uneven or undersized pad lets the wall flex and shortens tank life. The second mistake is overlooking what the fittings are made of: the bulkhead bodies are polypropylene with EPDM gaskets as the wetted seal, so confirm your inlet and outlet plumbing - and your contents - are compatible with polypropylene and EPDM, not just the polyethylene wall. The third is contents density: the 1.0 specific gravity rating means this tank is built for water and other liquids at or below water's density. If you are storing anything heavier than water, you need a higher-SG-rated tank, not this one - call us at 866-418-1777 and we will match you to the right one. Keep this one on water and water-like contents and it will give you a long service life.
Common uses for a 300 gallon vertical water tank
This is a workhorse vertical storage tank for bulk water holding - rural and remote sites, fire-water reserve, and water reuse trains all use tanks in this class. If you are building out a private fire-protection reservoir, our guide on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing and cold-climate freeze protection. For grey-water, rainwater, and HVAC condensate aggregation, see our breakdown of industrial water reuse tank topology.
This tank ships LTL freight from the Snyder plant in Merced, California, and freight is quoted live to your ZIP. Because it leaves a single California origin, freight cost is ZIP-dependent and can run high on long hauls to the East Coast - pull a real number before you commit with our Freight Cost Estimator, or call us at 866-418-1777 to confirm fittings, lead time, and delivery. We will help you size the right tank and get it to your site.
