The Snyder Industries 250 Gallon Open Top Batch Storage Tank (SII-573TDVOT-45) is a white polyethylene cylinder built for open-top batching, mixing, and bulk water storage where you need easy top access for hand-loading additives, dropping in a mixer shaft, or visually checking your level. It stands 68 inches tall on a 36 x 36 inch footprint, so it fits a tight pad while still holding a full 250 gallons. The open top is the whole point here: you get unobstructed access to the contents instead of working through a small fitted lid.
Will this open top tank work for your job?
At 250 gallons of water you are carrying about 2,085 pounds of contents, and the tank is rated to hold up to 3,962 pounds of contents at its 1.9 specific gravity rating. Two numbers to size against:
- Full of water: ~2,085 lb of contents
- Max rated contents: 3,962 lb at 1.9 specific gravity
Note that both figures are contents only and do not include the weight of the tank shell itself, so your total pad load is higher than 3,962 lb once the empty vessel is added. The 1.9 SG rating is the headline: this wall is built thick enough to carry dense contents by weight, not just water, which is unusual for an open top storage tank and gives you real structural headroom. To stay inside that rating, your fluid's specific gravity must be at or below 1.9. Run your actual fluid density and working volume through the Tank Sizing Calculator and the Tank Sizing Guide before you order, and remember an open top tank measures usable depth from the floor up with no headspace lid to fight.
The mistake to avoid
The 1.9 specific gravity rating tells you the wall can carry dense contents by weight, but an open top tank is open. It is not a sealed, vented closed storage tank, so it offers no fume containment, no pressure rating, and no protection against rain, debris, or evaporation. Do not treat this as a substitute for a closed batch tank if your process needs a sealed top. Just as important: this is an open-top batch vessel only and ships with no pre-installed fittings, bulkhead outlets, drains, or gaskets. No outlet or drain fitting is included, so specify any bulkhead and gasket separately for your service. Size your batches so the working level stays below the rim, since an open top gives you no overflow fitting to catch a runaway fill, and confirm any mixer or load you mount into the top is supported independently rather than hung off the tank wall. If you are pairing this reservoir into a larger water program, the industrial water reuse tank topology guide walks through staging quality-banded storage trains, and our concrete pad sizing guide covers building the right base under a loaded poly tank.

This open top storage tank ships LTL freight from the Snyder Industries plant in Marked Tree, AR, with freight quoted live to your ZIP. Because it ships from a single Arkansas origin, delivery to West Coast and other far-from-AR ZIPs runs materially higher, so get your exact number with the Freight Cost Estimator before you buy, or call 866-418-1777.
