The Snyder Industries 1500 Gallon vertical storage tank is a black, high-density linear polyethylene tank built to the ASTM D1998 standard for bulk water and liquid storage. It holds 1,500 gallons, stands 77 inches tall on an 89-inch diameter round footprint (89 x 89 envelope), and carries a 1.9 specific gravity rating - meaning the shell is rated to hold contents up to 1.9 times the weight of water, well beyond what water or process-water service demands. For rural fire reserves, agricultural supply, rainwater collection, and industrial process water, this is a heavy-duty vertical tank with real structural headroom.
Will it work for your site
Plan your pad and plumbing around real numbers. Filled with water, the tank and its contents weigh roughly 12,510 pounds, and the shell is rated to carry up to 23,769 pounds of contents at its full 1.9 SG rating. That load rides on the 89-inch round footprint, so you need a level, continuously supported base - compacted pad, concrete, or a full-diameter ring - rated for the filled weight. The tank comes fitted with a flange, an 18-inch polyethylene threaded and vented fitting, and a manway with 15-inch access for inspection and cleaning. The bolted flange and the manway both seal against gaskets, so confirm the gasket and bolt-kit size for those two connections when you spec your fittings, and match your inlet or outlet thread to the 18-inch PE threaded and vented port. Verify the exact fitting locations and elevations against the technical drawing on this page before you set the tank and commit your inlet, outlet, and vent runs.
Sizing it right
At 1,500 gallons this tank sits in the sweet spot for a private fire-water reservoir, a multi-day livestock or irrigation buffer, or rainwater storage feeding a pressurized system. If you are sizing a reserve against a target draw rate or a code-driven demand, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide. For fire-protection duty specifically, our guide on fire-water reservoir tank design walks through NFPA 22 sizing discipline and cold-climate freeze protection. If you are weighing containment or freeboard for a double-wall setup, our Snyder Captor freeboard sizing guide covers the usable-volume math under ASTM D1998.
One mistake to avoid
Don't over-buy on specific gravity without knowing why it matters. This shell is rated to 1.9 SG, which is generous for water service - but that rating is what lets it safely handle denser liquids down the road. If your contents are simply water, you have ample structural margin; if you are storing something heavier, the 1.9 rating is your ceiling, not a suggestion. Wall thickness is greatest at the base and thinnest up high near the vapor headspace, which is where HDPE tanks tend to age first - our piece on HDPE tank wall thickness at the vapor-saturated headspace explains why upper-shell inspection matters. And if you are storing something heavier or a reactive chemistry, our guide on when Snyder XLPE crosslinking matters explains where HDPE's 1.9 SG ceiling stops being enough.
