The Snyder Industries 250 Gallon HDPE Vertical Liquid Storage Tank is an ASTM-certified white polyethylene vertical tank standing 69 inches tall on a 40 x 40 inch footprint, built for general-purpose water and liquid storage. It carries a 1.9 specific gravity rating, which means the polyethylene wall is designed to hold liquids well denser than water without strain. Filled with water at 250 gallons, contents weigh roughly 2,085 pounds; at the full 1.9 SG rating the tank is approved to carry up to about 3,962 pounds of liquid. If you have been searching for a vertical storage tank, an HDPE 250 gallon storage tank, or a Snyder vertical tank, this is the unit that answers that need. Freight is the biggest cost unknown on a tank this size, so you can pull an exact number to your ZIP with the Freight Cost Estimator before you commit.
Will it work for your install?
The tank measures 69 inches high on a 40 x 40 inch footprint, so confirm your pad, overhead clearance, and access route before ordering. At 40 inches wide, the tank's diameter is the gating dimension for getting it on site: it will not pass a standard 36-inch doorway without tipping or maneuvering, so plan your route accordingly. The 40 x 40 inch footprint also sets the pad size you need to pour or level. Fittings on this tank include a flange, a 14 inch polyethylene threaded and vented lid, and a manway with 11-3/8 inch access for interior reach and cleaning. Check those three openings and their positions against the technical drawing on this page so your supply line, outlet plumbing, vent, and access hatch line up with how you intend to fill, draw, and service the tank. If you are still sizing the job, the Tank Sizing Calculator and Tank Sizing Guide walk you through matching capacity and footprint to your site, and the 250 Gallon Vertical Liquid Storage Tank buyer's guide covers this exact size in depth.
Specific gravity and what the 1.9 rating buys you
Water has a specific gravity of 1.0, so a 1.9-rated tank gives you real headroom over plain water storage. That rating is why this tank holds up to roughly 3,962 pounds of contents versus the 2,085 pounds of a full water load. If you are storing anything denser than water, match your liquid's specific gravity to this 1.9 figure and confirm the wetted hardware suits the liquid before you commit. For heavier service, the HDPE wall-thickness and ASTM D1998 sizing discussion explains where polyethylene tanks are designed to carry their load and why the vapor-side headspace matters as much as the liquid side.
A common mistake to avoid
The frequent error on a vertical tank this size is treating the 1.9 SG rating as if it also clears every chemical. The specific gravity rating speaks to the weight the wall can carry, not chemical resistance. The tank body is polyethylene, but the flange seal, its gasket, and the 14 inch vented lid are where a denser or aggressive liquid contacts non-tank materials first, so those are the parts to verify before you put anything other than water in this tank. The second common miss is openings and clearance: the flange, the 14 inch vented lid, and the 11-3/8 inch manway access dictate what equipment, plumbing, and hardware you can pass through and connect to, so plan your fill, draw, and service lines around those openings, not the other way around.
