The Snyder Industries 440 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a black vertical storage tank built for operators who need dependable bulk water storage in a compact 53-inch footprint. Molded from polyethylene with a 1.9 specific-gravity rating, it stands 69 inches tall on a 53 x 53-inch base and holds 440 gallons. The black exterior blocks light to discourage algae growth, making it a practical choice for outdoor water, fire-reserve, and rural site storage where you want the tank to stay dark inside.
Will this Snyder vertical storage tank work for your site?
Full of water, this tank carries about 3,670 pounds, so your pad has to be rated for that load across the 53 x 53-inch footprint. Because Snyder builds this one to a 1.9 specific-gravity rating, the shell is engineered to hold contents weighing up to roughly 6,972 pounds — nearly 90% of structural headroom above a plain water load, so an operator who may later move to a denser fluid is buying that margin on day one. That heavy-duty rating is the reason this black vertical tank shows up on so many demanding water-storage jobs. Plan around usable volume below the 440-gallon nameplate once you allow freeboard; our Snyder freeboard sizing guide per ASTM D1998 covers that math, and you can size the job with our Tank Sizing Calculator and Tank Sizing Guide.
Fittings and layout
Per the technical drawing on this page, this tank is configured with a flange and an 18-inch polyethylene threaded, vented lid. Reference that drawing for exact fitting locations and elevations before you plumb your inlet, outlet, and overflow, and confirm the vent path stays clear so the tank can breathe as it fills and drains. When you plumb the flange outlet, verify the bulkhead gasket material is rated for your service fluid and torqued per the drawing — the 1.9 SG shell rating does not extend to the gasket. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for supporting that 3,670-pound wet load.
A common mistake to avoid
Buyers often assume the 1.9 specific-gravity rating means this tank is pre-qualified for any heavy chemical. It is not. That number is the structural weight limit the shell is designed for — it says nothing about chemical resistance of the resin. This listing is for water and general bulk-storage service; if you are storing anything other than water, verify compatibility with the resin before you fill it. For fire-reserve and remote-site planning, our write-up on fire-water reservoir tank design for rural and remote sites covers sizing discipline and freeze protection for cold-climate service.
