The Snyder Industries 330 Gallon Heavy Duty Vertical Storage Tank is a 50-inch-tall polyethylene vertical tank on a compact 47 x 47-inch footprint, built for bulk water storage where floor space is tight and a tall profile beats sprawl. It carries a 1.9 specific gravity rating - the heaviest-duty rating Snyder applies to this line - and ships in Natural White so you can read the liquid level through the wall. If you are sizing a vertical storage tank for water staging, irrigation supply, a fire-water reserve, or general process water, this is a 330-gallon workhorse that holds its rating under real loads. One thing to factor early: it ships from California, so freight scales with distance - quote your ZIP before you commit.
Will it work for your site
Full of water, this tank weighs about 2,752 pounds, and the wall is rated to carry contents up to 5,229 pounds - that headroom is what the 1.9 specific gravity rating buys you, so the wall is not stressed when you store water near the top of its range. Set it on a level, fully supported pad: at a 47 x 47-inch footprint the base loading concentrates on a small area, so a flat concrete pad sized for the full water weight is the right foundation. See our concrete pad sizing guide for the ACI framework, and run your volume against the Tank Sizing Calculator or the Tank Sizing Guide before you settle on a size. If this tank is part of a grey-water, rainwater, or HVAC-condensate staging train, our industrial water reuse topology guide covers how to band storage by quality.
Nominal vs. usable, and reading the drawing
The 330 gallons is nominal capacity. Your working volume sits below that once you set an overflow and freeboard beneath the top fitting, so size to your real usable column, not the full 330 - our ASTM D1998 freeboard sizing guide walks through how to calculate it. The 50-inch height with the 47-inch diameter gives you a tall, narrow column of water, useful when floor space is scarce but it raises the fill point, so plan your pump head and overflow around it.
Confirm your ports before you plumb
Inlet, outlet, and overflow sizes are not published on this listing - you must read them from the technical drawing on this page before you order plumbing, fittings, or gaskets. The drawing is the authority for port placement and gives the dimensioned views you need for your tie-in. If you want fittings and gaskets spec'd to your service fluid rather than assumed, call 866-418-1777 and we will work them out with you - the 1.9 rating describes structural capacity for heavier contents, not chemical immunity, so anything denser or more aggressive than water needs the chemistry verified against the resin and gasket materials first. For pure water, irrigation, or a fire-water reservoir you are well inside the design envelope; if you are planning a rural or remote fire reserve, our fire-water reservoir design guide walks through NFPA 22 sizing and freeze protection.
This vertical storage tank ships LTL freight from the Snyder plant in Chowchilla, California, with the cost quoted live to your ZIP code - use the Freight Cost Estimator for a freight estimate, or call 866-418-1777 and we will quote it for you. Plan your foundation and fittings against the drawing, confirm your usable sizing, and we will get this 330-gallon vertical tank on the road to you.
