The Snyder Industries 8500 Gallon XLPE Vertical Liquid Storage Tank is a cross-linked polyethylene vessel rated to a 1.9 specific gravity, built in white for the heaviest water and high-density liquid duty. At 194 inches tall on a 120 x 120 inch footprint, it holds 8,500 gallons in a single vertical tank, and its XLPE construction is exactly what operators look for when they search for a vertical storage tank that can carry dense contents without compromise.
Will it work for your liquid?
Plain water fills this tank to roughly 70,890 pounds, and the 1.9 specific gravity rating means it is engineered to carry contents up to a maximum rated weight of about 134,691 pounds at full capacity. Put practically: across 8,500 gallons, that rating clears any liquid up to about 15.85 pounds per gallon. Compare that number against your own fluid's density and you have a clean go/no-go test before you order. That headroom is what separates a true XLPE storage tank from a standard 1.0 to 1.5 gravity water tank, and why this 1.9 unit is the right uptier when your contents run heavier than water. The cross-linked wall is structurally tougher than standard polyethylene, which is why XLPE is specified for demanding vertical storage service.
Fittings and plumbing
The technical drawing on this page shows three ports: a flange for the bulk inlet or outlet bolt connection, an 18-inch PE threaded/vented fitting that serves as the combined fill and vent, and a 12-inch by 24-inch fitting that reads as the manway access port. Review the drawing for exact placement and porting before you plumb. One honest caveat: gasket material and bolt torque are not on the drawing. The specific gravity rating governs the wall, not the seal, so confirm gasket compatibility against your specific liquid before you bolt up the flange. If you need secondary containment at this density, our guide to Snyder Captor double-wall freeboard sizing covers the double-wall path. Not sure 8,500 gallons fits your draw and refill cycle?

How it ships and what to have ready
This is a large-footprint vertical tank, so it moves by LTL freight quoted live to your ZIP. It ships from Snyder's plant in Lincoln, Nebraska, and we route from the nearest qualifying point on every order. Before you order, line up the receiving side: a level 10-by-10-foot pad rated for the filled mass (up to roughly 67 tons at maximum rated contents), overhead clearance above the 16-foot-2-inch height for vertical offload, and equipment on site to set it. LTL on a tank this size varies sharply by ZIP and offload needs, so pull an accurate number with the Freight Cost Estimator or call 866-418-1777 and we will quote it directly.
The mistake to avoid
The single most important number on this tank is the 1.9 specific gravity rating, and the most common mistake is ignoring it. That rating is what lets this XLPE tank carry liquids heavier than water; do not assume any plastic vertical tank can do the same, because a standard-gravity tank loaded with dense liquid is a wall-stress failure waiting to happen. Equally, do not under-size the venting. A tank this large moves significant air during fast fill and draw, which is why the 18-inch PE threaded/vented fitting matters; keep it clear and correctly specified so you never pull a vacuum or pressurize the headspace. Wall thickness and where vapor-side failures actually begin are worth understanding before service; see our guide on HDPE tank wall thickness at the vapor-saturated headspace.
