The Snyder Industries 5500 Gallon ASTM XLPE Vertical Storage Tank (SKU 7020000N40) is a crosslinked linear polyethylene (XLPE) vertical storage tank built to a 1.5 specific gravity rating, standing 221 inches tall on a 90 x 90 inch footprint in Natural White. It is a large-volume vertical tank for bulk water and heavy liquids, and the XLPE wall and 1.5 SG rating are what let it hold contents denser than plain water without exceeding its design limit. If you searched for a vertical storage tank, an XLPE tank, or a Snyder vertical tank in this size, this is the one.
Will it work for your site
At 5500 gallons, plan your pad and structure around real loaded weight, not just gallons. Full of water this tank carries about 45,870 lb; at its maximum rated 1.5 SG contents it reaches roughly 68,805 lb. That difference is the whole point of the 1.5 rating: it gives you headroom to store liquids heavier than water, but your concrete pad has to be sized for the loaded number you actually intend to run. The tank stands 221 inches (about 18.4 ft) tall, with the 18-inch PE threaded/vented fitting at the top, so plan fill and vent clearance above roughly 221 inches on top of the 90 x 90 inch footprint. For pad design, see our concrete pad sizing guide, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm this capacity fits your demand. Nominal 5,500 gallons is not fully usable volume once you store liquids heavier than water and account for freeboard; our Snyder freeboard sizing guide walks through the real volume you can run per ASTM D1998.
Fittings and access
Per the technical drawing on this page, the tank is configured with a flange, an 18-inch PE threaded/vented fitting, a S.U.M.O. outlet fitting for complete draining, and a fitting flat at 272.5 degrees for clean, square mounting of a side outlet. Access is through a manway with a 15-inch access opening for inspection and cleaning. Bulkhead fittings, gaskets, and valves are sized to the outlet and flange shown on the drawing and are supplied separately, so confirm thread size and clocking against the drawing before you order, since the outlet and flat locations are fixed by the mold.
The mistake to avoid
The common error on a tank this size is treating the 1.5 SG rating as free capacity. It sets the density ceiling, not a suggestion: if you fill it with a liquid heavier than 1.5 specific gravity, or size your pad for the water weight and then store something denser, you can overload both the tank wall and the foundation. Decide the heaviest liquid you will store first, then size the pad for that loaded weight up to the 68,805 lb rating. This tank is a strong fit for large water reservoirs, fire-water storage, and rainwater or reuse trains; see our fire-water reservoir design guide and industrial water reuse topology guide for sizing discipline on those applications.
