The Snyder Industries 10000 Gallon ASTM XLPE Black Double Wall Tank (SKU 1006600N46) is a crosslinked linear polyethylene double wall tank built for high-volume bulk storage where a secondary containment wall is required. It holds 10,000 gallons in a 226-inch-tall body on a 142 x 142 inch square footprint, and its black XLPE construction carries a 1.5 specific gravity rating - meaning it is engineered to hold contents up to 1.5 times the density of water. As an ASTM XLPE tank, its wall thickness and freeboard are governed by the same ASTM D1998 sizing logic that determines how much of the 10,000-gallon volume you can actually put to work.
Will it work for your site?
Plan around the footprint and the loaded weight before anything else. This tank occupies a 142.0 x 142.0 inch base and stands 226 inches tall, so verify overhead clearance and a level, engineered pad. Note that the 142-inch width is wider than a standard 12-foot door or gate opening, so confirm your access path can take it and that a crane or forklift on site is rated for the empty crate at offload. Filled with water it carries roughly 83,400 lb, and at its full 1.5 SG rating the contents can reach about 125,100 lb - the pad and any structural support underneath have to be sized for that load, not for the empty tank. The integral double wall provides built-in secondary containment, which is why this configuration is chosen for installations that need interstitial protection without pouring a separate containment basin. If you are still confirming which capacity matches your draw and refill cycle, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide.
Fittings and access
Per the technical drawing on this page, this tank is configured with a flange, an 18-inch PE threaded/vented fitting, and a manway with 15-inch access. That 15-inch manway access is your entry point for internal inspection and cleaning of the primary wall, and it ties directly into the double-wall monitoring the containment design depends on. Confirm the fitting locations and elevations against the drawing before you set piping. On the flange and the 18-inch PE threaded/vented port, select the gasket elastomer for the product you are storing - XLPE resin compatibility does not guarantee that an EPDM or Viton gasket is right for the same service, and a mismatched gasket is the most common install miss on a tank like this.
The mistake to avoid
The specific gravity rating is where high-density fills go wrong. A 1.5 SG rating is the ceiling: it means the wall is built for contents up to 1.5x water density, and it is not a license to fill with anything heavier. Match your actual product's specific gravity to the tank rating, and if you are storing a chemical rather than water, verify chemical compatibility for XLPE resin against the manufacturer's concentration- and temperature-specific chart before committing. For deeper background on how double-wall freeboard and wall thickness behave under real service, see our guides on Snyder Captor double-wall freeboard sizing per ASTM D1998 and wall thickness at the vapor-saturated headspace. For buried outer-wall installations, our cathodic disbondment testing reference covers the polyethylene boundary condition.
This tank ships LTL freight from the Snyder plant in Lincoln, NE, and freight is quoted live to your ZIP - get a real number with our Freight Cost Estimator or call 866-418-1777. Because of the 226-inch height and multi-ton loaded weight, plan for offload equipment rated for the crate at delivery.
