The Snyder Industries 4100 Gallon ASTM XLPE Black Vertical Storage Tank is molded from crosslinked linear polyethylene and carries a 1.5 specific-gravity rating, so it holds bulk water and denser liquids that stay within that 1.5 SG limit. It stands 100 inches tall on a square 120 x 120-inch footprint and holds 4,100 gallons in a single black vertical tank body. If you are comparing "vertical storage tank" and "XLPE storage tank" options at this capacity, the weights and fitting layout below are what decide the install.
Will it work for your site?
Filled with plain water this tank carries roughly 34,194 pounds of contents; loaded to its full 1.5 SG rating it reaches about 51,291 pounds. That loaded figure, not the gallon count, is what your pad and foundation have to carry, so build the base to 51,291 pounds from day one. This is a water-service tank rated to 1.5 SG for denser liquids; the ASTM XLPE construction named in the product title is what earns that density headroom. Run your volume and pad numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you order, and for above-ground concrete work our concrete pad sizing guide walks the ACI 360R-10 framework.
Fittings and configuration
The tank includes an 18-inch PE threaded manway for access and inspection, a flange fitting, and eight flat fitting pads spaced at 45 degrees. Those flat pads ship un-drilled: the installer locates each penetration on the pad and seals it with a gasketed bulkhead fitting, which means you supply the bulkhead hardware and gaskets sized to your plumbing. See the technical drawing on this page for exact fitting elevations and pad orientations, and confirm gasket and bulkhead sizing against it before ordering plumbing. For fire-water or reserve duty, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection, and the industrial water-reuse topology guide helps if this tank joins a grey-water or rainwater train.
The mistake to avoid
The common error at this size is designing the foundation around the water weight and ignoring the SG rating. This tank is rated to 1.5 SG precisely because it can hold contents heavier than water, so if you ever store a denser liquid your pad has to carry the full 51,291-pound loaded figure. Confirm your intended contents against the loaded weight, not the 34,194-pound water weight, before you build.
This Snyder tank ships empty on LTL freight from the Marked Tree, Arkansas plant, quoted live to your ZIP — so the freight weight is the empty tank, not the 51,291-pound loaded figure.
