The Snyder Industries 500 Gallon Open Top Batch Storage Tank (SII-578TDVOT-45) is a white polyethylene cylinder built for open-access batch, transfer, and bulk water storage where you load product by hand, dip a sample, or inspect from the top. It holds 500 gallons in a 48-inch diameter, 77-inch-tall body on a 48.0 x 48.0 footprint, so it sits on a standard 4x4 pad or pallet footprint while going vertical for capacity. The open top lets you load, blend, and inspect without fighting a sealed lid, and the molded polyethylene wall carries a 1.9 specific gravity rating for handling contents heavier than water.
Will this open top tank work for your batch?
Run the weights before you set it. Filled with water this 500 gallon tank carries about 4,170 lb, and it is rated to a maximum contents weight of 7,923 lb at its 1.9 specific gravity rating - that headroom is why an open top batch tank like this handles dense water-based contents, not just plain water. Confirm your finished batch density lands at or under that 1.9 rating. This ships as a bare open-top vessel; outlet and bulkhead fittings and any lid are configured and quoted by phone at 866-418-1777, so call with your plumbing plan before you order. If you are still deciding between sizes, the Tank Sizing Calculator and Tank Sizing Guide walk you through capacity, footprint, and weight together.
The mistake to avoid
Two things trip people up on an open top tank. First, the open top is not a pressure or fully sealed configuration - it is meant for atmospheric, vented batch and storage duty, so do not plan it into a closed, pressurized, or fully contained process. Second, size your pad to the loaded weight, not the water weight: buyers routinely engineer the pad to the 4,170 lb water figure and under-build it, when the real design load is the 7,923 lb maximum at the 1.9 rating. If your concentrated mix pushes past that 1.9 ceiling, you need a higher-rated vessel - call 866-418-1777 and we will spec one. Match the tank to your real batch weight, not just the gallon number, and you will get full service life out of the wall.
Freight and how to order
This 500 gallon storage tank ships LTL freight from Snyder's plant in Marked Tree, AR, with the rate quoted live to your ZIP - get an exact number from our Freight Cost Estimator or by calling 866-418-1777. Because freight on a tank this size depends heavily on your delivery point and any liftgate or limited-access needs, pull a quote before you commit so there are no surprises. See the technical drawing on this page for body and footprint details. If this open tank is headed into a fire-water reserve, a reuse train, or a fresh concrete pad, our guides on fire-water reservoir tank design, industrial water reuse tank topology, and concrete pad sizing for above-ground polyethylene tanks cover the engineering details.
