The Snyder Industries 1500 gallon vertical dome top water tank in white stores 1,500 gallons in a rotationally molded polyethylene body measuring 86 inches across the base and 72 inches tall. Snyder rates this tank to a 1.9 specific gravity, meaning the wall is built for liquids well heavier than water - so for bulk water storage, fire reserve, and rainwater capture, the wall thickness is headroom you do not have to engineer around. This is the kind of 1500 gallon vertical water tank people buy when they want one tank to outlast the application.
Will this tank work for my site
Plan around the loaded weight, not the gallon number. Filled with water this tank holds 12,510 pounds of contents, and the structure is rated to carry up to 23,769 pounds at its full 1.9 specific gravity. Both numbers point to the same requirement: the base underneath has to be engineered for the load. A vertical tank this size needs a level, continuous foundation that fully clears its 86-inch round footprint - a reinforced concrete pad (a square pour of at least 86 inches per side works) or a properly compacted base - so the load spreads evenly and the tank sits true. If you are still settling on capacity, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit. The white body limits light penetration compared with a natural translucent tank, which helps slow algae growth in stored water, though you give up the at-a-glance level check a translucent wall offers.
The dome top and your plumbing
The dome top is a working feature, not just a shape. Its curvature distributes vacuum and pressure loads across the top of the tank and supports foot traffic for inspection access. For how that geometry carries load and ties into fall-protection anchors, see our guide on tank dome curvature engineering. Outlet size, fitting locations, and lid size are not pre-published as separate specs here - they are shown on the technical drawing on this page, so check the drawing against your plumbing plan and use it to spec mating bulkhead fittings, valves, and gaskets before you order. If this tank anchors a private fire-protection supply, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection, and the industrial water reuse guide walks through grey-water, rainwater, and HVAC condensate aggregation if you are building a reuse train.
The mistake to avoid
The most common error on a tank this size is the foundation, not the tank. People size the pad for the empty shell or for the water weight alone and forget that a vertical poly tank set on an uneven or partial base will distort and stress the wall over time. Build the base for the full 12,510 pound water load across the complete 86-inch round footprint, keep it flat and continuous, and never set the tank on a point load. For more on planning a vertical tank installation of this class, see our 1500 gallon vertical liquid storage tank buyer's guide, and confirm the dimensions in that guide against this tank's 86 x 72 inch geometry before you plan around them.
