The Snyder Industries 6000 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank is a crosslinked linear polyethylene (XLPE) vertical storage tank rated to a 1.9 specific gravity, giving it headroom for liquids well above the density of water while the listed capacity here is 6,000 gallons of water in Natural White. It stands 145 inches tall on a 120 x 120 inch footprint. If you are sizing a vertical storage tank for a water reserve, fire-water supply, or a heavier liquid duty, the 1.9 SG rating and the XLPE wall are what separate this Snyder from a standard HDPE tank.
Will it work for your site?
Full of water, the tank carries roughly 50,040 lb of contents; the 1.9 SG rating raises the maximum rated contents weight to about 95,076 lb, so denser liquids stay within the tank's design. Size the concrete pad and offload rigging to that loaded 95,076 lb ceiling, not the 50,040 lb water case — that is the number your foundation and crane plan have to carry. The 120 x 120 inch footprint sets the pad and clear working area you need; our Tank Sizing Calculator and Tank Sizing Guide help you match capacity to that footprint before you commit. Because crosslinking matters once the chemistry gets aggressive, the Snyder XLPE vs HDPE guide is worth reading if you are deciding between wall materials.
Fittings and access
The technical drawing on this page shows the fitting layout: a flange, an 18-inch PE threaded/vented fitting, and a manway with a 15-inch clear access opening for interior inspection and cleanout — a detail that matters for keeping a water tank serviceable over its life. Confirm each fitting size and elevation against the drawing before you order accessories or set your plumbing, since inlet, vent, and outlet placement drive how the tank ties into your system. When you order bulkhead or flange accessories, match the gasket material and bolt pattern to the flange and confirm the 18-inch PE threaded fitting's thread form — XLPE fittings and their gaskets have to be spec'd to the liquid you are storing, not just to the tank. For above-ground installs, review our concrete pad sizing framework so the foundation matches that loaded weight.
One thing not to get wrong
The 1.9 SG rating is the tank's ceiling, not a target. Match the rating to your actual liquid density, and keep freeboard in mind for thermal expansion — the freeboard sizing per ASTM D1998 walks through the real usable volume you get after allowing for expansion. If this tank is a fire-water reserve, the rural fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection.
