The Snyder Industries 7500 Gallon ASTM Black Heavy Duty Vertical Storage Tank is built for large-volume bulk water and liquid storage where footprint and vertical height both matter. This black polyethylene vertical storage tank is rated to a 1.9 specific gravity, standing 234 inches tall on a 102 x 102 inch square footprint. At that size it holds 7,500 gallons and answers the three questions that matter before you buy: will it hold what I need, how does it ship, and what mistake do I need to avoid.
Will it work for your site
Filled with water, this tank carries roughly 62,550 pounds of contents, and its 1.9 specific gravity rating gives design headroom up to about 118,845 pounds of rated contents for denser liquids. That 1.9 SG rating is the reason this is a heavy-duty ASTM tank rather than a standard water tank: the wall is engineered for heavier-than-water service. Treat the 118,845-pound figure as the wall's design ceiling, not a target fill; for water storage you are only at roughly 62,550 pounds. The 102 x 102 inch footprint means your pad and containment need to be sized for a full 8.5-foot square base, and at 234 inches tall the tank needs level, engineered support underneath it. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the volume against your draw and refill cycle, and see our Snyder freeboard sizing per ASTM D1998 guide for how thermal expansion and density affect the volume you can actually use.
Fittings and access
The drawing package on this tank includes:
- Flange
- 18" PE threaded / vented fitting
- Manway with 15" access
- 12" x 23" fitting
- Flat fitting location
The vented 18-inch fitting matters on a tank this large: rapid fill and draw move a lot of air, and adequate venting keeps the tank from pulling a vacuum or pressurizing. The manway with 15-inch access gives you interior entry for inspection and cleaning. Confirm your riser and bulkhead thread and gasket match the 18-inch PE threaded fitting and the flat fitting location before you order, and verify every port position and elevation against the technical drawing on this page.
The mistake to avoid
Do not undersize the foundation or skip the vent. A 7,500-gallon tank at over 62,000 pounds full concentrates enormous load on its base; an uneven or underbuilt pad is the most common cause of premature failure on tanks this size. If you are planning a fire-water reservoir or reuse train, our guides on rural fire-water reservoir design, concrete pad sizing for above-ground polyethylene tanks, and industrial water reuse tank topology walk through the engineering that keeps a vertical storage tank of this scale stable and serviceable.
This Snyder vertical tank ships by LTL freight from the Lincoln, NE plant, quoted live to your ZIP because of its size and weight.
