Snyder Industries 275 Gallon Open Top Dish Bottom Tank with Cover

The Snyder Industries 275 Gallon Open Top Dish Bottom Tank (SII-574TDVOT-45) is a 15-degree cone-bottom vessel built for batching, mixing, and controlled-drain water service where you need the tank to empty cleanly from the bottom instead of pooling on a flat floor. It holds 275 gallons, stands 58.5" tall on a 42" diameter footprint, and ships with a 47" cover for open-top access. The shell is white High Density Linear Polyethylene rated to a 1.5 specific gravity and a 120 F / 48 C maximum service temperature, and the 15-degree sloped bottom keeps contents moving toward the outlet.

Will it work for your job

Empty, the tank weighs just 85 lb, so one or two people can position it before it's plumbed. Filled with water it carries roughly 2,294 lb, and at its full 1.5 specific-gravity rating it will hold up to about 3,440 lb of contents — size your stand and pad around the heavier of those two numbers, not the water figure. Because the base is a 15-degree cone rather than a flat floor, this tank must sit in a matching cone-bottom stand; it is not built to stand on its own on a slab. The 1.5 SG rating covers water and heavier-than-water fluids by weight — confirm your fluid's specific gravity against that 1.5 ceiling before you commit. This tank is built to Snyder spec numbers 2282, 2285, and 3492 (see the technical drawing on this page for the referenced standards). As an open-top 275-gallon poly reservoir, it's also a sensible fit for rural or remote fire-water storage; our guide on NFPA 22 fire-water reservoir sizing covers that use case. For headroom, pad, and access checks, the Tank Sizing Calculator and Tank Sizing Guide walk through the math.

Getting the cone and outlet right

The most common cone-bottom mistake is sizing the discharge for water when the tank is actually running solids or slurry. A 15-degree cone drains reliably, but the outlet diameter is what decides whether the bottom empties or bridges and plugs. Before you specify a bulkhead, read our cone-bottom outlet sizing guide and the companion breakdown of 1-inch vs 1.5-inch vs 2-inch bulkhead drain times. If the loaded tank lives on a poured pad, size that pad against the full 3,440 lb rating using the ACI 360R-10 pad framework. See the technical drawing on this page for exact port and cover geometry before you order fittings.
