The Snyder Industries 80 Gallon HDLPE Square Dual Containment Tank is a double-wall vessel built so a spill from a primary drum, day tank, or chemical-feed station gets caught before it ever reaches the ground. At 43 inches tall on a compact 24 x 24 inch square footprint, it tucks into a corner, a pump skid, or a feed station without eating floor space, and the integrated outer wall is the containment basin, so there is no separate dike to pour or maintain. The inner tank is molded from High Density Linear Polyethylene (HDLPE) in white, with an 80-gallon nominal capacity and a specific gravity rating of 1.9. This is one of the square double wall tanks buyers reach for when a round containment footprint will not fit the space.
Will it work for your application
Footprint is 24.0 x 24.0 inches with an overall height of 43 inches, so confirm your overhead clearance for filling and lid access before you set it. Filled with plain water at a specific gravity of 1.0, the inner tank carries roughly 667 lb; at its full 1.9 SG rating the inner wall is engineered to hold up to 1,268 lb of contents. That spread is worth noting: on plain water the wall is operating at roughly half its rated content weight, which is real headroom you can verify yourself from the two numbers. The 1,268 lb figure is the one that matters when you site the tank on a pad, mezzanine, or steel stand. Run those weights through the Tank Sizing Calculator and the Tank Sizing Guide when you are matching the tank to a drum count, day-tank turnover, or a required containment volume.
Because this is a square double-wall containment tank, the 1.9 SG rating is doing real work: it tells you the heaviest liquid the inner wall is qualified to hold. The most common mistake here is treating that SG number as a formality. Match it to your actual fluid density and confirm chemical compatibility for HDLPE before you commit the tank to any chemical service. For the engineering behind that decision, the guide on Captor double-wall freeboard sizing per ASTM D1998 and the SPCC 40 CFR 112 compliance walkthrough cover freeboard, thermal expansion, and how a tank like this fits the containment side of a compliance plan. One thing the data sheet cannot do for you: confirm the outer basin holds at least the volume your rule requires against your largest primary container. Check that containment volume on the technical drawing on this page before you specify it for SPCC duty.
Fittings and siting
Fitting and outlet configuration is shown on the technical drawing on this page and confirmed at order, so refer to that drawing for fitting locations and dimensional detail before you plumb it in. If you want it nailed down before you buy, call 866-418-1777 and we will confirm the spec. A double-wall tank concentrates its full rated load onto that small 24 x 24 inch footprint, so the surface underneath has to carry it. If this is going on a poured slab, the concrete pad sizing framework (ACI 360R-10) covers how to size the pad for an above-ground polyethylene tank, and for cold-climate or rural reserve and fire-water duty the remote fire-water reservoir design guide covers freeze protection and sizing discipline.
Freight
This Snyder square double-wall tank ships LTL freight from the Snyder plant in Marked Tree, Arkansas, quoted live to your ZIP code. The compact 24 x 24 footprint keeps it a manageable LTL load, but transit time varies with your distance from Arkansas.
