The Snyder Industries 550 Gallon XLPE Vertical Liquid Storage Tank (SKU SII-1800000N42) is a 550-gallon vertical storage tank molded in cross-linked polyethylene with a 1.9 specific gravity rating, white in color, standing 75 inches tall on a 48-by-48-inch footprint. Two numbers define this tank: the XLPE wall and the 1.9 SG rating. Cross-linked polyethylene gives a tougher, more impact- and stress-crack-resistant wall than standard HDPE, and the 1.9 rating means it is built to hold liquids up to 1.9 times the weight of water at full volume - heavier-liquid headroom most water-grade verticals do not carry.

Will it work for your application?
Filled with water, this tank carries roughly 4,587 pounds of contents. Because it is rated to 1.9 specific gravity, it is rated for up to 8,715 pounds of contents at full volume, which is the headroom that lets you store liquids heavier than water without exceeding the wall rating. Confirm the specific gravity of your liquid against that 1.9 ceiling, and check it against the technical drawing on this page, before you fill. The vertical, flat-bottom design at 48 by 48 inches sets directly on a level, fully supporting pad. If you are sizing for a fixed pad or a defined liquid level, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide, and see the model-specific 550 Gallon Vertical Liquid Storage Tank buyer's guide for layout and use-case detail. For above-ground installs, confirm your pad is engineered for the loaded weight using our concrete pad sizing guide.
Freight: ships LTL, quoted to your ZIP
This is a full-size vertical tank and moves by LTL freight, not parcel. Snyder molds this line at three plants - Marked Tree, AR; Lincoln, NE; and Philippi, WV - so it ships from whichever is nearest your delivery address to hold transit time and cost down. Eyeball the closest plant to your region, then get a real number: freight is quoted live to your delivery ZIP rather than baked into the list price, so use the Freight Cost Estimator for your address, or call 866-418-1777 to lock in a quote.
The mistake to avoid
The error to watch on a vertical XLPE storage tank like this one is treating the 1.9 SG rating as a free pass. The rating tells you the tank can hold a heavier-than-water liquid at the listed volume, but it does not address chemical attack on the cross-linked wall, the gaskets, or any fitting hardware. Fitting, bulkhead, and gasket configuration is not specified in this listing - confirm it from the technical drawing on this page or by phone at 866-418-1777 before you order. Cross-linked polyethylene also cannot be re-welded or repaired the way linear HDPE can, so plumb it correctly the first time and keep the fill within the rated weight. Verify your liquid's compatibility with XLPE and confirm the working specific gravity before committing the tank to service.
Whether you are setting up bulk water storage, a fire-water reservoir, or an industrial water-reuse train, this Snyder vertical XLPE storage tank gives you a proven platform. Rural and remote fire-protection users should review our fire-water reservoir design guide before specifying. Get your freight number with the Freight Cost Estimator or by calling 866-418-1777.
