The Snyder Industries 275 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a polyethylene vertical storage tank built for bulk water and general liquid storage where you need a compact 47-inch footprint. It stands 59 inches tall on a 47 x 47 inch base, holds 275 gallons, and carries a 1.9 specific-gravity rating - meaning the wall is engineered to hold contents up to 1.9 times the weight of water. On a black Snyder vertical tank this size, that rating is the reason to choose it: it handles not just water but denser-than-water liquids up to that 1.9 gravity ceiling.
Will it work for your job?
Filled with water at roughly 8.34 lb per gallon, this tank carries about 2,294 lb of full water weight, and its structure is rated for contents up to 4,358 lb - the reserve built into the 1.9 SG heavy-duty wall. Plan your slab and anchoring for the loaded weight, not the empty shell. The tank comes with a flange, an 18-inch polyethylene threaded/vented top fitting, and a manway with 15-inch access. The 18-inch threaded/vented fitting is your fill and vent point; the manway's 15-inch clear access is what governs whether a person, hose, or cleaning tool can reach inside for service. See the technical drawing on this page for exact fitting placement, and confirm outlet gaskets and any bulkhead seals by phone before you plumb - the drawing shows locations, not supplied hardware. If you are matching this vertical storage tank to a demand schedule, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide so you buy the right gallonage the first time.
Placement and the mistake to avoid
The common misstep on a tank this tall-and-narrow is setting it on uneven or undersized ground. A 59-inch column of liquid concentrates load on the base, so it needs a full, level, continuous support pad - not blocking or a partial ring. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework. One geometry check before it arrives: the 47-inch width has to clear any door or gate on the path to its spot, since it ships upright and can't be safely laid down once filled. If this tank feeds a rural fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection, and for reclaimed-water setups see our industrial water reuse tank topology breakdown.
Freight and how to order
This tank ships LTL freight, quoted live to your ZIP, from the Snyder plant in Marked Tree, Arkansas - the nearest fulfillment point for this SKU. Buyers east and central of Arkansas generally see lower LTL than West Coast destinations, so get an exact number for your ZIP with our Freight Cost Estimator before you commit, or call 866-418-1777 and we will size the tank, confirm fittings and seals, and quote delivery to your site.
