The Snyder Industries 4400 Gallon Vertical Storage Tank is a black, crosslinked linear polyethylene (XLPE) tank built to ASTM standards for heavy-duty water and liquid storage. Molded to a 1.9 specific gravity rating, it carries a wide margin over plain water and works as a reservoir-scale unit for high-volume bulk storage, rainwater and fire-water reserves, agricultural supply, and process water. It stands 182 inches tall on a 90 x 90 inch square footprint, so plan your slab, overhead clearance, and offload before it arrives.
Will it work for your site?
This is a full 4,400-gallon vertical storage tank in black XLPE. Filled with water it carries about 36,696 lb of contents, and at its 1.9 specific gravity rating it is engineered for a maximum rated contents weight near 69,722 lb — that headroom is what lets it hold denser-than-water liquids without exceeding the wall rating. Those numbers drive your foundation: a level, continuously supported concrete pad rated for the full loaded weight is not optional at this size. Run your volume and duty cycle through the Tank Sizing Calculator and Tank Sizing Guide, and review our concrete pad sizing framework before you pour.
Fittings and access
The technical drawing on this page shows the tank configured with the following fittings. Confirm the exact quantity and size of each against the drawing before you plumb it:
- Flange
- 18" PE threaded/vented fitting
- Manway with 15" access
- 2–3" S.U.M.O. fitting
- 12" x 14" fitting
- Flat fitting location
Vent sizing matters on a tank this tall, and the 15" access manway sets how you inspect and clean it. Because this is a 1.9-SG unit likely to see denser or more aggressive contents, spec your bulkhead, flange, and manway gasket materials to the stored chemistry and the higher hydrostatic head — gasket and fitting material is selected separately from the tank itself.
Why the 1.9 SG rating matters
The 1.9 specific gravity rating is a wall rating, not a limit to water service — it is what qualifies this XLPE tank for contents heavier than water. If you are weighing crosslinked polyethylene against standard HDPE, our guide on Snyder XLPE vs HDPE explains when crosslinking earns its place, and the Captor freeboard guide per ASTM D1998 covers usable volume and freeboard at higher specific gravity. For rural and remote fire-protection duty, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
Delivery and clearance
At 182 inches tall (about 15.2 ft) on a 90 x 90 inch (7.5 ft square) base, this tank exceeds standard door and overhead heights and needs forklift or crane offload — plan the delivery site accordingly. The common mistake at this scale is under-building the base or ignoring the vent: a 182-inch column of liquid develops real head pressure, so the pad, the anchoring, and the vent all have to match the full loaded weight rather than the empty tank.
