The Snyder Industries 4900 Gallon ASTM Black Heavy Duty Vertical Storage Tank is built for high-volume bulk water storage on sites that need a large, rugged footprint. It stands 202 inches tall on a 90 by 90 inch base, holds 4,900 gallons, and is rotationally molded from black polyethylene. What sets this model apart is its 1.9 specific gravity rating: the wall is engineered to carry contents up to 1.9 times the density of water, so the same shell handles brines and heavier liquids that would over-stress a standard 1.0 to 1.5 SG water tank. As a black heavy-duty polyethylene vertical tank, it is built to the ASTM D1998 standard for the family.
Will it work for your site?
Full of water this tank weighs about 40,866 pounds, and its wall is rated to carry contents up to 77,645 pounds. That headroom is where the 1.9 SG rating shows up in the numbers, and both figures drive your pad and structural planning long before delivery day. The loaded tank must sit on a level foundation that fully supports the entire 90 by 90 inch base. Run your volume against usable freeboard with the Tank Sizing Calculator and the Tank Sizing Guide, and if you are pouring a slab, our guide on concrete pad sizing for above-ground polyethylene tanks covers the ACI 360R-10 framework for a tank this size.
Fittings and access
The tank is configured with a flange, an 18 inch PE threaded and vented fitting, and a manway with 15 inch access for inspection and cleaning. Plumbing points include a 2 to 3 inch S.U.M.O. fitting, a 12 by 14 inch fitting, and a flat-fitting location. Each outlet seals with its matching bulkhead fitting and gasket, so confirm gasket material against your stored fluid before install. Verify every fitting size and position against the technical drawing on this page before you set piping, since these locations are fixed at the mold.
Sizing for bulk and reserve storage
A 4,900 gallon black vertical storage tank is a common backbone for rural fire-water reserves, irrigation supply, and industrial water reuse trains. For fire-protection reserve planning, see our guide on fire-water reservoir tank design for rural and remote sites; for grey-water, rainwater, or HVAC condensate aggregation, our write-up on industrial water reuse tank topology covers quality-banded storage. The most common mistake on a tank this size is underbuilding the foundation for the loaded weight rather than the empty shell, so plan the pad around that 40,866 pound water load.

Note that the 202 inch height is over standard door and overhead clearance, so verify vertical clearance and truck access at the delivery site.
