The Snyder Industries 290 Gallon Vertical Storage Tank is molded in black crosslinked linear polyethylene (XLPE) with a 1.9 specific-gravity rating. It stands 72 inches tall on a round 36-inch diameter footprint (36 x 36 inches). If you are sizing a vertical storage tank for water, fire reserve, or heavy liquid duty and want the durability of a crosslinked wall over standard HDPE, this is the tank that answers those questions with hard numbers rather than marketing.
Will it work for your application?
At a nominal 290 gallons, a full load of water weighs about 2,419 pounds, and the tank is rated to carry contents up to roughly 4,595 pounds thanks to the 1.9 SG wall rating. That headroom is the practical reason to choose XLPE here: crosslinked polyethylene carries a higher specific-gravity rating than standard HDPE, so it handles denser liquids without derating the wall. If you are weighing the two materials, the Snyder XLPE vs HDPE guide walks through exactly when crosslinking earns its keep. Confirm your working volume against the actual liquid you plan to store using the Tank Sizing Calculator and the Tank Sizing Guide.
Fittings and plumbing
This tank comes configured with three access and connection points:
- Outlet flange (confirm the outlet size against the technical drawing on this page)
- 18-inch PE threaded and vented lid
- Manway with 15-inch access for interior reach and cleaning
Because the pack does not carry a numeric outlet size, read the flange and fitting dimensions off the technical drawing on this page before you plumb the tank. For any flanged or threaded connection on a poly tank, confirm the flange gasket and any bulkhead or threaded fitting are rated for your specific liquid and the tank's service before install; on a flanged outlet, the gasket and bulkhead selection are what decide whether the connection holds.
Site prep and support
A vertical storage tank of this size needs full, continuous support under the entire base. The 36-inch diameter should sit on a level pad sized and finished for the loaded weight, not just the empty shell. For above-ground concrete pad detailing, the concrete pad sizing framework lays out the ACI reference boundaries. If this is going into a rural or remote fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
The mistake to avoid
Do not assume the 1.9 SG rating means you can skip checking your liquid's actual density and freeboard. The rated wall protects the tank; it does not size your working volume. Fill to the tank's intended level, account for thermal expansion, and never treat the full-shell capacity as usable volume. The freeboard sizing guide shows how ASTM D1998 freeboard and expansion math change the real volume you can actually use.
