The Snyder Industries 4750 Gallon Open Top Batch Storage Tank is a cylindrical, open-top vessel molded from high density linear polyethylene in white, standing 101 inches tall on a 120-inch diameter. The open top gives you full overhead access for mixing, manual dosing, batch blending, or dropping in agitators and float assemblies without working through a narrow fill port. If you store, batch, or aggregate water and water-based fluids and want to work from the top down, this is the size and geometry built for it.
Will it hold what you need it to?
Rated for 4,750 gallons, this open top tank carries a 1.9 specific gravity rating, so the wall is engineered with structural margin above plain water. Filled with water alone the contents weigh 39,615 pounds, and the shell is rated to carry up to 75,268 pounds of contents at its full SG rating. Treat that 1.9 figure as a safety ceiling for water and water-based process fluids, not an invitation to run heavier chemistry, and confirm the actual density of your contents against it. Because this is an open top design, plan your freeboard so wave action, aeration, or foaming during mixing does not carry over the rim, and check your working batch height against the 101-inch wall. If you are unsure whether this diameter and volume fit your throughput, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit.
Siting a tank this size
Here is the number that drives your foundation: design the pad and any anchoring to the 75,268-pound fully rated ceiling, not the 39,615-pound water fill. A flat-bottom cylinder on a 120-inch diameter needs continuous, level support across the entire base, and our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that foundation right. If this open top storage tank feeds a rural or remote fire-water reservoir, the NFPA 22 fire-water reservoir design guide covers sizing discipline and freeze protection. If it is part of a reuse or aggregation system pulling grey water, rainwater, or HVAC condensate together, the industrial water reuse tank topology guide covers how to band and sequence storage trains.
The mistake to avoid
Our data does not specify factory fittings, outlets, or overflow on this tank, so do not assume a bulkhead or drain configuration. Confirm the fitting layout, gasket material, and any overhead access against the technical drawing on this page before you design plumbing into the installation, and verify the confirmed wall height and dimensional layout there rather than working from the nominal numbers alone.
