The Snyder Industries 3900 Gallon Vertical Storage Tank is a heavy-duty XLPE (crosslinked linear polyethylene) black vertical tank built for large-volume water and bulk liquid storage. It stands 163 inches tall on a 90 x 90 inch footprint and carries a 1.9 specific gravity rating, meaning the wall is rated for liquids substantially heavier than water. If you need a durable, high-capacity vertical storage tank in a compact square footprint, this is a serious workhorse.
Will it work for your site?
At 3,900 gallons, plan your foundation and plumbing around the loaded weight, not the empty shell. Full of water, contents alone run 32,526 lb, and at the tank's maximum 1.9 SG rating the contents can reach 61,799 lb. That is a lot of concentrated load on a 90 x 90 inch base, so a properly engineered, level pad is not optional. To match capacity to your usage and confirm the pad, use the Tank Sizing Calculator and the Tank Sizing Guide; for above-ground foundation detailing, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework. A black vertical tank at this capacity is a common choice for rural and remote bulk-water and fire-reservoir duty; if that is your application, our write-up on fire-water reservoir tank design and NFPA 22 sizing covers the discipline behind it. Because black resin blocks light and discourages algae growth, this tank suits outdoor storage where clear or translucent walls would be a liability.
Usable volume and the 1.9 SG rating
The 1.9 SG rating is more than a spec line: the wall is rated for liquids up to roughly 1.9 times the density of water, which is where the 61,799 lb maximum-contents figure comes from. Practically, the same tank that stores water can also hold heavier bulk liquids, so the purchase is not locked to a single duty. Just remember that rated capacity and the volume you can actually fill are not identical once you account for freeboard and thermal expansion at higher density; our guide on Snyder freeboard sizing per ASTM D1998 explains the real usable volume behind the nameplate number.
Fittings and access
This vertical tank comes configured with a flange, an 18-inch PE threaded and vented fitting, a manway with 15-inch access, a 10 x 12 inch S.U.M.O. fitting, and a flat-mount S.U.M.O. fitting. The 15-inch manway access supports cleaning, inspection, and internal service. Confirm the fitting layout and elevations against the technical drawing on this page before you set piping, since inlet, outlet, and vent positions drive your connection plan.
Why crosslinked polyethylene
The crosslinked (XLPE) wall gives this Snyder tank added structural memory and impact resistance compared with standard HDPE, which is why the 1.9 SG rating is achievable at this size. If you are weighing XLPE against HDPE for a heavier or more demanding duty, our guide on Snyder XLPE vs HDPE walks through when crosslinking earns its keep.
