The Snyder Industries 4400 Gallon ASTM XLPE Vertical Storage Tank (SKU 5210000N40) is a large-format vertical storage tank molded in crosslinked linear polyethylene (XLPE), rated to a 1.5 specific gravity and finished in Natural White. It stands 182 inches (about 15'2") tall on a 90 x 90 inch footprint, so before you order, check that a doorway or gate will clear 90 inches wide and your overhead will clear 182 inches, and confirm your slab will accept a tank this tall. At full water the contents weigh 36,696 lb; the 1.5 SG rating means the shell is built to carry up to 55,044 lb of contents. Those two numbers drive the pad and site work far more than the tank itself does.
Will it work for your site?
This is a vertical tank sized for bulk water: well and pressure-system buffering, irrigation, or a fire-water reservoir where a tall, small-footprint vessel fits the yard better than a squat one. The crosslinked XLPE wall and 1.5 SG rating give you real headroom over the 1.0 SG of plain water: the same tank carries denser contents up to 1.5 SG / 55,044 lb with no derate, so a future move to a heavier liquid won't cost you a new vessel the way a water-only tank would. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 4,400 gallons matches your draw-down and refill cycle before committing to a tank this size.
Fittings and access
Per the technical drawing on this page, this tank carries a flange, an 18" PE threaded/vented fitting, a manway with 15" access, a 2"–3" S.U.M.O. fitting, a 12" x 14" fitting, and a flat fitting; confirm the exact port count and elevations against that drawing, since your inlet, outlet, and overflow have to land where your piping needs them. The manway with 15" access is your entry point for interior inspection and cleaning. Seal the flanged and bulkhead-style ports with gaskets and thread sealant rated for the stored fluid, and follow the fitting's gasket and torque spec rather than reusing mismatched hardware, which is what starts weeps on XLPE ports.
Site prep — the mistake to avoid
The single most common error on a tank this tall is an inadequate foundation. Full water puts more than 18 tons on the pad, but because this shell is rated for 55,044 lb (27.5 tons) of contents, size the slab to your intended service weight, not just the water case, to stay consistent with the 1.5 SG rating. A vertical XLPE tank must sit on a level, fully supporting, smooth base — no point loads, no partial bearing — or you risk stress at the base knuckle. Review Concrete Pad Sizing for Above-Ground Polyethylene Tanks for the ACI framework, and if this is a rural fire-water reservoir, the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing and freeze protection.
