The Snyder Industries 15000 Gallon XLPE Black Heavy Duty Vertical Storage Tank is a crosslinked polyethylene (XLPE) vertical storage tank built for large-volume water and bulk liquid duty. It holds 15,000 gallons, stands 234 inches tall on a 143 x 143 inch footprint, and carries a 1.9 specific gravity rating - the top of the range shown, meaning the wall is engineered for liquids substantially heavier than water with no need to step up to a stronger unit. On plain water you keep a wide safety margin: full to the brim the tank carries roughly 125,100 lb of contents against a 237,690 lb maximum rated contents weight, leaving about 112,590 lb of headroom - close to a 1.9x cushion over a full water load.
Will it work for your site?
This is a black vertical storage tank in crosslinked linear polyethylene (XLPE). Crosslinking gives the wall better impact and stress-crack resistance than standard HDPE, which is why Snyder builds heavy-duty verticals this way - see our guide on Snyder XLPE vs HDPE for where crosslinking earns its keep. The black resin blocks light transmission, which discourages algae growth in stored water. On the plumbing side, this model offers a large 12" x 26" fitting location plus an 18" PE threaded/vented port, a flange, and a flat fitting location - so you can confirm up front whether it accepts your line size and vent. For service access, it carries a manway with 15" access, which is what lets an installer inspect and clean a 234-inch-tall tank. Confirm the exact positions and sizes against the technical drawing on this page before you plumb inlet, outlet, overflow, and vent. If you are still confirming volume against draw-down and refill rates, run the numbers through our Tank Sizing Calculator and Tank Sizing Guide.
Foundation and freight planning
A tank this size needs a proper base. At 15,000 gallons of water the loaded weight is over 125,000 lb bearing on a 143 x 143 inch footprint, so the pad has to carry it. Our write-up on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that base right. If this is a rural fire-water reservoir, the NFPA 22 reservoir design guide covers sizing discipline and cold-climate freeze protection; for grey-water, rainwater, and HVAC condensate reuse trains, see our water reuse tank topology breakdown.
One mistake to avoid
The 1.9 SG rating tells you the wall is heavy-duty, but it does not make this a chemical tank by default. XLPE handles many chemistries better than HDPE, but chemical service depends on the specific chemical, concentration, and temperature - not on the tank being crosslinked. Keep this unit on water and compatible bulk liquids unless you have verified the exact chemistry, and remember the flange and the 18" PE threaded/vented port are the interfaces where gasket and elastomer compatibility matters - spec those connections to your service.
