The Snyder Industries 8500 Gallon ASTM XLPE Vertical Storage Tank is a heavy-duty bulk vertical storage tank built from crosslinked linear polyethylene (XLPE) with a 1.5 specific gravity rating, engineered for large-volume water and high-density liquid storage where a taller, footprint-conscious profile matters. At 194 inches tall on a 120 x 120 inch footprint, it holds a full 8,500 gallons in a single vertical column, and the XLPE resin plus 1.5 SG rating give you real headroom for liquids heavier than water.
Will this tank work for your site?
Full of water at 8.34 lb/gal, this tank carries roughly 70,890 pounds of contents; at its full 1.5 specific gravity rating it is engineered to hold up to 106,335 pounds. Those numbers drive your pad design more than anything else — a load of this magnitude belongs on an engineered, level concrete pad sized for the footprint and the loaded weight, not on bare soil or gravel. At 194 inches — 16 feet 2 inches — this is a rigging and clearance decision, not just a spec line: confirm door height, crane reach, and any low-clearance road access against that height, and size your lift for the delivered tank before it arrives. The 120 x 120 inch footprint also means checking overhead clearance for fill and vent access on the pad.
Matching the fittings to your plan
Standard fittings per the technical drawing include a flange, an 18-inch PE threaded/vented fitting, and a 12 x 24 inch fitting — see the technical drawing on this page for exact placement and elevations. Treat these as a checklist against your P&ID: the 18-inch PE threaded/vented fitting serves as the fill and atmospheric venting point, the flange gives you a bulkhead-style outlet connection, and the 12 x 24 inch fitting is your access and inspection port. Confirm each one lines up with your inlet, outlet, vent, and access plan before ordering. And confirm the flange and threaded-connection gasket material suits your liquid before filling — the fitting hardware, not just the tank wall, sets the connection's chemical limit at a 1.5 SG service.
Sizing and pad planning
Before you commit, run your numbers through our Tank Sizing Calculator and read the Tank Sizing Guide so the working volume matches your draw and refill cycle. For the foundation, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and the ACI 318 boundary for a tank this size. If this is a fire-water reservoir, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, see our industrial water reuse tank topology guide.
The mistake to avoid
The most common error on a tank this large is treating the 1.5 SG rating as a license to skip pad engineering. The rating tells you the wall thickness can handle a dense liquid; it does not carry the 106,335-pound loaded weight for you. Undersize or unlevel the foundation and you invite uneven stress on the tank wall. Match the pad to the loaded weight and keep it dead level. If you're storing anything other than water, confirm chemical suitability separately before filling — this listing covers a water-service vertical XLPE storage tank.
