The Snyder Industries 3000 Gallon HDPE Vertical Chemical Storage Tank in white is a 1.5 specific-gravity vessel built for serious chemical service. It stands 127 inches tall on a 90 x 90 inch square footprint and holds 3000 gallons in a polyethylene wall rated for contents up to 1.5 specific gravity. If you are sizing a vertical storage tank for an HDPE chemical feed, batching, or bulk-storage skid, this is the size class that anchors most mid-volume installations.
Will it work for your application
Start with weight, because that drives your pad and your tie-downs. Filled with water this Snyder tank carries roughly 25,020 pounds; at its maximum rated 1.5 specific gravity it reaches about 37,530 pounds of contents. Your foundation has to be a level, continuous slab capable of carrying that fully loaded weight across the 90 x 90 inch footprint without point-loading the bottom. The 1.5 specific-gravity rating is the number that matters for chemical work: it tells you the heaviest liquid this wall thickness is engineered to hold, and going heavier than 1.5 means you have chosen the wrong tank. Run your exact liquid and fill height through the Tank Sizing Calculator, and if you are still deciding between sizes, the Tank Sizing Guide walks through capacity, footprint, and headroom together. Fittings are not pre-specified in this listing: the tank ships per the technical drawing's standard fitting configuration, so confirm exact outlet size and placement with us at 866-418-1777 before ordering.
Chemical compatibility
This is a polyethylene tank with a 1.5 specific-gravity rating. The product name reflects the listing as HDPE, but the exact resin grade is the one item to confirm before chemical service - call us at 866-418-1777 to verify HDLPE versus XLPE, because that distinction changes what the wall will tolerate over time. The compatibility below is drawn from the OEM chemical-resistance chart, which is concentration- and temperature-specific; verify your actual operating conditions against it before you commit.
At or below 1.5 specific gravity, this tank is a fit for chemicals including acetic acid at 60% (PP or PVC fittings, EPDM gaskets), aluminum sulfate at 50% (PVC, EPDM), calcium chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS fittings, EPDM), ferrous sulfate at 20% (PVC, EPDM), magnesium chloride at 30% (PVC, EPDM), sodium carbonate at 30% (PVC, EPDM), urea solution at 50% (PP or PVC, EPDM), and ozonated water up to 10 PPM (PVC, EPDM). Match your fitting and gasket materials to the chemical, not just to the tank.
Some chemicals are heavier than this 1.5-rated tank should carry and need the 1.9 specific-gravity version of this same 3000-gallon Snyder vertical - a direct same-size, same-line swap rather than a redesign. That list includes ethylene glycol, ferric chloride, ferric sulfate, hydrochloric acid (PVC fittings, Viton gaskets), hydrofluoric acid (Viton), hydrofluosilicic acid, hydrogen peroxide (Viton), peracetic acid (316SS fittings, Aflas gaskets), phosphoric acid (Viton), polyaluminum chloride, potassium carbonate, potassium hydroxide, propylene glycol, sodium bisulfate, sodium bisulfite, sodium hypochlorite (Viton), sodium thiosulfate, sulfuric acid (CPVC fittings, Viton gaskets), and zinc orthophosphate. If your application is on that list, talk to us before ordering so we put you on the right wall thickness. Full data lives in our Chemical Compatibility Database.
The mistake to avoid
The two errors that cost real money here are matching the wrong fitting material and assuming all polyethylene is the same. Several of the chemicals above call for Viton or Aflas gaskets and 316SS or CPVC bulkheads rather than the default EPDM and PVC - sodium hypochlorite, hydrogen peroxide, and sulfuric acid are the classic traps - and an aggressive oxidizer on the wrong elastomer will fail long before the tank does. For instrumentation on a chemical feed tank, our guide on tank level gauge selection for chemical service covers radar, ultrasonic, hydrostatic, and magnetostrictive trade-offs, and if you need secondary containment, the Snyder Captor Plus 110% containment vs UL-142 comparison lays out the options.

This tank ships LTL freight from the nearest Snyder Industries plant - Lincoln, NE or Philippi, WV - and we route from whichever of the two is closer to your ZIP, which is a real cost difference between a Midwest and an East Coast origin. Get your number on the Freight Cost Estimator, or call 866-418-1777 and we will confirm the right wall rating, the fittings, and the closest shipping point for your install. Review the technical drawing on this page for fitting locations and overall dimensions before you finalize your layout.
