The Snyder Industries 1500 Gallon ASTM XLPE Double Wall Tank is built for operators who need contained, high-density storage without running a separate berm or external dike. Inner and outer walls are molded from crosslinked linear polyethylene (XLPE) to ASTM standards and rated to a specific gravity of 1.9, with the interstitial space between them serving as integrated secondary containment. At 1500 gallons it measures 76" H x 93" W x 93" L (a 93" x 93" footprint), holds full water weight at 12,510 lb, and carries a max rated contents weight of 23,769 lb at the top of its 1.9 SG range. Ships LTL from Snyder plants in California or Nebraska, quoted to the plant nearest your delivery ZIP. Confirm your pad and any anchoring plan account for the loaded weight, not the empty tank.
Will it work for your site
The natural white XLPE shell lets you read the liquid level through the wall, which matters on a double wall tank where you cannot see the inner vessel directly once it is set. Top fittings are short and purposeful:
- 18" PE threaded/vented top opening (fill and vent)
- Manway with 15" access (inspection and cleanout)
The 18" PE threaded port accepts standard PE threaded adapters and gasketed connections; confirm the exact thread and gasket against the fitting layout on the technical drawing on this page. For matching capacity to your draw and refill schedule, run the numbers through the Tank Sizing Calculator and cross-check the Tank Sizing Guide before committing to this 1500 size.
The XLPE and SG point worth understanding
The most common mistake on a tank like this is treating the 1.9 specific gravity rating as a recommendation to fill it with the heaviest fluid you can find. The rating is a structural ceiling, not a target. For plain water service the 12,510 lb full-water figure governs your foundation; the 23,769 lb max-contents number only comes into play at the top of the SG range. This is the 1.9 SG (heavy-duty) build, so if you only need water, that headroom is structural margin you are buying. Crosslinked polyethylene gives a tougher, more impact- and stress-crack-resistant wall than standard linear material, which is why this is a double wall XLPE construction rather than a single-skin water tank. If you are sizing freeboard for thermal expansion or density on a Snyder double wall, the Snyder Captor double-wall freeboard sizing guide works through the ASTM D1998 logic, and the wall-thickness-at-the-headspace guide covers where these walls actually wear.
Containment and fire-water use
Because secondary containment is built into the tank, this 1500 gallon unit suits sites where a single contained footprint is cleaner than an external dike. If you are evaluating it as a rural or remote fire-water reservoir, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection for cold-climate service.
