The Snyder Industries 250 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 250-gallon polyethylene vertical storage tank that stands 64 inches tall on a 36 x 36 inch square footprint - compact enough for a tight corner, pad, or trailer bed while still holding a serious volume of water. What sets it apart is the wall: molded in black to the ASTM heavy-duty standard, it carries a 1.9 specific-gravity rating, meaning the shell is engineered to hold contents up to 1.9 times the weight of water. On a water tank that is an unusually stout wall, and it is the reason to choose this SKU over a standard 1.0 or 1.5 SG vertical tank - you get headroom to store a denser liquid down the road without buying a new tank.
Will it work for your site?
Filled with plain water this tank carries roughly 2,085 lb. Because the 1.9 SG wall is validated to a maximum rated contents weight near 3,962 lb, that heavier figure - not the water weight - is what you size the base to. Spread 3,962 lb across the 36 x 36 inch footprint and you are asking the pad to carry about 3 psi of bearing, concentrated and full-contact, so a level, continuously supported base is not optional. Build the footing for the rated max regardless of what you plan to store first. If you are still settling capacity or stand height, run it through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit; for a poured base, our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI framework.
Fittings and access
Per the technical drawing on this page, this vertical tank is configured with a flange outlet, an 18-inch polyethylene threaded and vented lid, and a manway with 15-inch access for interior reach - handy for cleaning, inspection, or dropping in a level sensor. Two things to verify against the drawing before you plumb: the flange outlet needs a gasket and bulkhead fitting sized and matched to your piping - that seal is a separate item you supply to fit your line - and the vented lid is what keeps the tank from pulling a vacuum on drawdown, which matters if this feeds a fire-water reservoir or a cold-climate system. Confirm every fitting location and size on the drawing so your tie-in and vent routing land where you expect.
