The Snyder Industries 250 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 250-gallon polyethylene vertical storage tank whose real distinction is its 1.9 specific-gravity rating. Where a standard-duty vertical is built for plain water (1.0 SG), this ASTM Heavy Duty wall is engineered for contents up to roughly 3,962 pounds on the same compact 40 x 40 inch footprint. That over-built wall is the reason to step up to this tank: it holds denser liquids without exceeding its rating, and it handles water with a wide margin. It stands 69 inches tall, so it fits well houses, tight equipment rooms, and pad corners where a wider tank will not go, and the black color blocks light to slow algae growth in outdoor and semi-outdoor service.
Does this tank fit your job?
Match the tank in two steps: footprint and weight. The 40 x 40 inch base and 69-inch height decide whether it clears your doorway, ceiling, and pad. The weight decides your foundation. A 250-gallon fill of plain water is about 2,085 pounds on that small base, but because the wall is rated to 1.9 SG, size your pad to the full rated load of 3,962 pounds if you plan to store anything denser than water. Either way, a level, load-bearing pad matters. Run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide, and for pad detailing use the concrete pad sizing guide for above-ground polyethylene tanks. If you are working out usable volume and freeboard on a Snyder heavy-duty wall, the ASTM D1998 freeboard guide explains the thermal-expansion math behind the rating.
Fittings and access
This vertical tank comes with a flange, a 14-inch polyethylene threaded and vented lid, and a manway with 11-3/8 inch access for reaching inside to clean or inspect. The vented lid lets air move in and out as the water level rises and falls, preventing the vacuum that can deform a sealed tank on drawdown. Confirm the exact fitting locations, heights, and outlet position against the technical drawing on this page before you plumb, since the drawing is the controlling reference for this model. Its light-blocking build also suits grey-water, rainwater, and condensate reuse trains, covered in our water reuse topology guide.
Freight and how to order
This 250 gallon vertical storage tank ships by LTL freight from the Snyder plant in Marked Tree, Arkansas. Tank freight depends on the distance from Arkansas to your delivery ZIP plus dock or liftgate needs, so we quote it live rather than bundling it into the list price. Get a real number in seconds with our Freight Cost Estimator, or call 866-418-1777 and we will size the tank, confirm the fittings, and price the freight to your address.
