The Snyder Industries 5000 Gallon ASTM XLPE Double Wall Tank (SKU 5630000N42) is a crosslinked linear polyethylene double wall tank built for high-density, containment-critical storage where a secondary wall is a requirement, not a nice-to-have. It stands 216 inches tall on a 102 x 102 inch footprint, holds 5,000 gallons, and carries a 1.9 specific gravity rating in Natural White resin. Because this is a self-contained double wall design, the inner tank and its integral outer containment ship as one unit, so you get secondary containment without pouring a separate concrete dike.
Will it work for your site
Confirm the numbers before you set a pad. Full of water this tank weighs about 41,700 lb, and its 1.9 SG wall rating means the body is engineered to carry contents up to roughly 79,230 lb at maximum density. Size your foundation and structural support to the loaded weight, not the empty shell. The 102 x 102 inch square footprint and 216 inch height also drive your clearance and overhead access planning. Fittings on this unit include a flange, an 18-inch PE threaded and vented opening, and a manway with 15-inch access. That vented 18-inch opening matters on a tank this size: fast fill and draw can pull a vacuum or build pressure, so match your venting provision to your actual draw rate. The 15-inch manway access also sets a real limit on what fits through it — verify your fill hardware, level sensors, and cleaning tools clear that opening before you specify them. See the technical drawing on this page for exact fitting locations and elevations, and use our Tank Sizing Calculator and Tank Sizing Guide to match capacity and freeboard to your usage.
The mistake to avoid
The most common error on a tank this size is treating the 1.9 SG rating as headroom you can ignore. That rating tells you the tank body is rated for heavier-than-water contents, but you still have to design freeboard and support for real thermal expansion and fill behavior. Two more details protect the containment claim: the flange and manway connections only stay watertight with correctly rated gaskets and seals torqued to Snyder's drawing, and the interstitial space between the walls only does its job if you monitor it for inner-wall leaks. Our guide on Snyder Captor double-wall freeboard sizing per ASTM D1998 walks through the usable-volume math, and the wall-thickness at the vapor-saturated headspace guide explains why the upper wall is where premature failures start. For fire-water reservoir duty, the NFPA 22 reservoir design guide covers sizing discipline for rural and remote sites.
Freight
This Snyder XLPE double wall tank ships LTL from the plant in Lincoln, Nebraska, quoted live to your ZIP. At 216 inches tall and shipping empty as one unit, this is an oversize freight item that needs forklift or crane offload rated for the shell — get a real number before you order by running your ZIP through the Freight Cost Estimator, or call 866-418-1777 to lock in delivery and confirm offload equipment for a tank this size.
