The Snyder Industries 4100 Gallon XLPE Vertical Liquid Storage Tank in white is a large cross-linked polyethylene vessel built for bulk water and high-density liquid storage. It stands 130 inches tall on a 102 x 102-inch base and carries a 1.9 specific gravity rating, the spec that separates this vertical storage tank from a standard water-only vessel. Filled with water it holds roughly 34,194 pounds, and at its 1.9 SG rating it is engineered for contents up to 64,969 pounds. That headroom is why this Snyder XLPE tank gets specified for jobs heavier than water alone.
Will it work for your install?
The body is cross-linked polyethylene (XLPE) molded in white and rated to 1.9 specific gravity. XLPE is the cross-linked grade of polyethylene Snyder uses on tall vertical tanks built for higher specific-gravity contents. The base needs a level, full-contact pad sized for the loaded weight above. At 130 inches tall on a 102 x 102-inch footprint, this is a tall vessel: design the pad to carry the full 64,969-pound maximum rated load spread across roughly 72 square feet (about 900 pounds per square foot), and plan tie-down anchoring against wind and seismic overturning, not just bearing load. The foundation should never become the weak link.
The fitting package shown on the technical drawing for this tank includes a flange, an 18-inch PE threaded and vented fitting, a manway with 15-inch access, a 12 x 23-inch fitting, and a flat fitting landing. The manway with 15-inch access is your entry, inspection, and cleanout point; the 18-inch PE threaded and vented fitting serves as both the vent and a threaded landing for plumbing. Match your valve, bulkhead-fitting thread, and gasket sizes to those drawing callouts before you order, and confirm fitting elevations against the technical drawing on this page. The 18-inch vent matters on a tank this size: large vertical tanks must breathe freely as they fill and drain, and an undersized or restricted vent can collapse or balloon a tank during fast transfer. Use the Tank Sizing Calculator and Tank Sizing Guide to match this 4100-gallon vertical tank to your draw rate and reserve needs.
The mistake to avoid
The 1.9 SG rating is a ceiling, not a free pass. It means the wall is built for liquids up to 1.9 times the weight of water, but it is not a chemical-resistance approval. If you only store water, a lower-SG vertical of the same capacity will cost less; choose this 1.9 XLPE tank specifically when your contents outweigh water or you want maximum wall safety margin. Match your actual liquid's specific gravity to the rating, and verify chemical compatibility separately against the manufacturer's resistance chart before storing anything other than water. The second common miss is the vent: keep that 18-inch vented PE fitting clear and never cap it. For fire-water and rural reserve applications, the fire-water reservoir design guide walks through NFPA 22 sizing and cold-climate freeze protection that apply directly to a tank this size.
Compare other vertical sizes
If 4100 gallons is more capacity than you need, the buyer's guides for the 2000-gallon vertical tank, the 500-gallon vertical tank, and the 300-gallon vertical tank cover the smaller XLPE verticals in the same family so you can size up or down with confidence.
