The Snyder Industries 250 Gallon ASTM XLPE Double Wall Tank (SKU 5990502N42) gives operators secondary containment in one piece instead of a tank plus a separate berm. A primary tank nests inside an outer wall, creating a self-contained interstitial space in a tight 34 by 34 inch footprint that stands 83 inches tall. The shell is crosslinked linear polyethylene (XLPE) rated to 1.9 specific gravity, in natural white, fitted with a 14-inch PE threaded and vented opening plus a manway with 11-3/8-inch access for fill, inspection, and pump-out.
Will it work for your site?
This is a double wall tank with a 250 gallon capacity. With an 83-inch height over a 34 by 34 inch footprint, it keeps the ground footprint small while the height carries the volume, so confirm overhead clearance and door or roll-up height before it arrives. The gap between the primary and outer wall is your leak-detection zone, which is the reason to buy double-wall over a single tank inside a berm, so plan how you will monitor it visually or with a sensor. For the openings, you get the 14-inch PE threaded/vented top fitting and the manway with 11-3/8-inch access shown on the technical drawing on this page; match your inlet and vent hardware to those before install rather than after. Cold-climate water and fire-reserve buyers should review our fire-water reservoir design guide, which covers NFPA 22 sizing and freeze protection.
How heavy does it get, and how does it ship?
Plan your pad and equipment around the loaded weight. Filled with water, the contents alone weigh about 2,085 pounds. At the full 1.9 specific gravity rating, the contents can reach up to 3,962 pounds, so if you are running anything denser than water, size your slab, ring, or skid to that maximum number, not the water figure. Neither figure includes the tank's dry weight, which is not listed here, so factor that into your forklift and pad math before delivery. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the capacity and footprint fit your job, and review our guide to Snyder double-wall freeboard sizing under ASTM D1998 so you account for thermal expansion and usable volume rather than assuming all 250 gallons is workable headroom.
The mistake to avoid
The 1.9 specific gravity rating is the headline spec on this XLPE double wall tank, and it is where buyers slip. Engineered to 1.9 SG, it carries real headroom over typical water-only tanks rated near 1.0 to 1.5, so you are paying for the capability to hold denser contents without re-buying. But that rating is a ceiling, not a chemical clearance: a 1.9 SG wall is built for liquids up to 1.9 times the density of water, which does not mean every fluid is a match. The crosslinked polyethylene resin and the fitting and gasket materials set the chemical limits together, so when you thread fittings or seat the manway cover, verify the gasket or o-ring material alongside the resin, not just the tank wall. Check your fluid against the OEM chemical-resistance chart at your actual concentration and temperature before you commit. For water, fire-reserve, and general bulk storage, this tank is a clean fit.
