The Snyder Industries 4650 Gallon ASTM Black Heavy Duty Vertical Storage Tank (SKU 8210000N51) is a molded polyethylene vertical storage tank built to the ASTM standard and rated to a 1.9 specific gravity, so it holds the heaviest contents in its class without downgrading the wall. Hard dimensions: 154 inches tall on a 102 x 102 inch square footprint (102.0 x 102.0 in), delivering 4,650 gallons in a compact ground area. Finished in black, this is a straightforward black vertical storage tank for bulk water and heavy-liquid storage where you need volume and a heavy-duty wall.
Will it work for your site
Fill this tank with water and you carry about 38,781 pounds of contents; at its full 1.9 specific gravity rating the wall is engineered for up to 73,684 pounds of contents. Both figures are contents weight only and exclude the tank shell, so design the pad and structure to the 73,684 lb rated load, not the water load, if you are storing anything denser than water. The technical drawing on this page shows an 18-inch PE threaded/vented fitting, a 12-inch x 13.75-inch S.U.M.O. flat fitting, additional S.U.M.O. and flat S.U.M.O. fittings, a flange, and a manway with 15-inch access for interior reach. The 18-inch vented fitting and the 15-inch manway access are your two interior-entry and venting points, so match your bulkhead fittings and gaskets to those exact openings before you plumb the site. Run your capacity and headspace numbers through our Tank Sizing Calculator and the Tank Sizing Guide so the tank matches the draw and refill rate you actually need.
Sizing and pad discipline
A tank this heavy lives or dies on its foundation. A 102 x 102 inch footprint carrying up to 73,684 pounds of rated contents needs a properly designed slab, which our guide on concrete pad sizing for above-ground polyethylene tanks walks through under the ACI 360R-10 framework. Because this is an ASTM D1998-class Snyder tank, set your freeboard and thermal-expansion allowance with our Snyder freeboard sizing guide so the usable volume matches the rated volume. If you are sizing for fire reserve or freeze-prone service, the fire-water reservoir design guide covers NFPA 22 sizing discipline for exactly this kind of large vertical storage tank.
Freight
This tank ships LTL freight from the Snyder plant in Marked Tree, Arkansas, quoted live to your ZIP code. A 4,650 gallon vertical tank moves as an oversize LTL load, so get an accurate number before you order using our Freight Cost Estimator, or call 866-418-1777 and we will quote it to your delivery address. The listed price is before freight; freight is quoted separately to your ZIP.
