The Snyder Industries 250 Gallon ASTM XLPE Double Wall Tank gives you secondary containment in a single unit: the outer wall fully encloses the inner tank, so you get a built-in catch basin instead of buying and building a separate dike. The tank holds 250 gallons in a compact 34-by-34-inch footprint and stands 83 inches tall. The shell is molded in black crosslinked linear polyethylene (XLPE) and rated to a specific gravity of 1.9, which means it is engineered to hold liquids substantially heavier than water.
Will it work for your application?
Water fills this tank to roughly 2,085 pounds at 250 gallons. Because the tank is rated to 1.9 specific gravity, its maximum rated contents weight is 3,962 pounds, so it has real headroom for denser liquids without overloading the wall. That 1.9 rating is the reason to choose this double-wall unit over a single-wall water tank: for plain water or light-duty service you are paying for containment and heavy-liquid capability you may not use, while for dense chemistries such as brines and fertilizers up to 1.9 SG, the rating is exactly the fit. Size your installation against the full-weight figure, not the empty tank: run your liquid through the Tank Sizing Calculator and read the Tank Sizing Guide if you are deciding between this and another size.
Footprint and fittings to confirm
This is a tall, narrow tank: 83 inches high on a 34-by-34-inch base is roughly a 2.4-to-1 height-to-width ratio. Keep the pad dead plumb and load-rated, and consider strapping or anchoring in exposed or seismic locations, because a slender profile carrying up to 3,962 pounds is unforgiving of a tilted slab. Fitting and bulkhead details are not listed in the spec table, so confirm fitting sizes, locations and gasket material against the technical drawing on this page before you order plumbing or mating connections. Do not assume a configuration the drawing does not show.
Double-wall sizing and the mistake to avoid
Double-wall polyethylene tanks have their own sizing logic. The usable volume you can actually fill is governed by freeboard and thermal expansion, not just the nameplate gallons, and crosslinked walls behave differently at the vapor-saturated headspace than people expect. Before you commit a fill level, read our guide on Captor double-wall freeboard sizing per ASTM D1998 and the companion piece on wall thickness at the vapor-saturated headspace, where premature failures tend to originate. If this is going into a private fire-water or reservoir role, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. The common error on a double-wall tank is treating the interstitial space as an afterthought: if the outer wall is ever buried or paired with steel, coating adhesion under cathodic polarization becomes a real design question, and our writeup on cathodic disbondment testing per ASTM G8, G42 and G80 walks through the boundary condition.
