The Snyder Industries 850 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank (SKU 1810000N42) is a 48-inch-diameter vertical storage tank standing 117 inches tall, molded in Natural White crosslinked linear polyethylene (XLPE) and built to ASTM XLPE construction. It carries a 1.9 specific-gravity rating, meaning the tank wall is engineered to hold contents up to 1.9 times the density of water at its full 850-gallon volume. For plain water or rainwater duty, that rating gives you a wide structural margin.
Will it work for your site?
This is a full 850-gallon vertical tank on a 48.0 x 48.0 inch footprint, so it drops onto a standard 4-foot pad or ring. The numbers your pad, deck, or stand has to carry:
- Diameter: 48 in
- Height: 117 in
- Footprint: 48 x 48 in
- Water-filled weight: ~7,089 lb
- Max rated contents weight (at 1.9 SG): 13,469 lb
Size the base for the fluid you actually intend to store rather than for water alone. Fitting and manhole configuration is confirmed at order - call 866-418-1777 to verify the outlet size and lid you need. Run your volume-versus-height numbers through our Tank Sizing Calculator or the Tank Sizing Guide before you commit to a pad size.
Why XLPE on a water tank
Crosslinked polyethylene is the heavy-duty version of the polyethylene used in most storage tanks. The molding process bonds the polymer chains into a single crosslinked network, which raises impact resistance and environmental stress-crack resistance compared with standard HDPE. On a water or fire-reservoir tank, that toughness translates into longer service life outdoors and better resistance to repeated fill-and-draw cycles. Our guide on Snyder XLPE vs HDPE walks through when crosslinking earns its keep, and if you are using this as a private fire-water reserve, the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing and freeze protection for cold-climate sites.
The mistake to avoid
Do not size the pad or the tie-downs off the water weight. A 1.9-SG tank invites heavier fluids, and if you fill it with a denser liquid the contents weight climbs toward that 13,469 lb maximum. Build the foundation and any anchoring for the actual density you will store, and keep the tank on a level, fully supported base. Our Captor freeboard and density sizing guide covers how thermal expansion and fluid density cut into the volume you can actually use, and our Concrete Pad Sizing guide lays out the ACI framework for above-ground pads.
This vertical storage tank ships LTL freight from the nearest Snyder plant to your ZIP, with shipping points in Lincoln, NE; Marked Tree, AR; and Philippi, WV - so coverage spans the Plains, mid-South, and Mid-Atlantic. Because of its size and weight, freight is quoted live to your delivery ZIP rather than included in the list price.
