The Snyder Industries 710 Gallon HDPE Vertical Liquid Storage Tank is a 68-inch-tall vertical storage tank on a 60 x 60 inch footprint, molded in white polyethylene by Snyder Industries and built to ASTM D1998 design standards. At 68 inches tall over a 60-inch-square base, it sits as a squat, near-1:1 vertical rather than a tall, tippy column, which makes it a stable pick for outdoor and standby siting. It carries a 1.9 specific gravity rating, so it handles dense liquids well past the weight of water without exceeding its design envelope. Filled with water it holds 5,921 pounds at the full 710 gallons; its maximum rated contents weight runs to 11,251 pounds, which is the number that matters once you store anything heavier than plain water.
Will it work for your liquid?
The 1.9 SG rating is the headline spec on this Snyder vertical tank, and it is the real differentiator. Most commodity vertical HDPE in this size carries a 1.5 SG rating; a 1.5-rated 710-gallon tank tops out near 8,900 pounds of contents, while this Snyder is rated to 1.9 SG and a full 11,251 pounds. A tank rated to 1.9 carries liquids up to 1.9 times the density of water at full volume without overstressing the wall, which covers a broad range of water, agricultural, and industrial liquids. Match your liquid's specific gravity against that 1.9 ceiling before you fill it: stay at or under the rating and the 11,251-pound contents number is your hard limit at full level. Outlet, plumbing, and tie-down design all follow from those weights, not from the gallon figure alone. If you are unsure how much capacity your application actually needs, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a size.
Fittings, access, and sealing
This HDPE storage tank comes configured with a flange, an 18-inch PE threaded and vented fitting, and a manway with a 15-inch access opening for cleaning and inspection — plan that as a confined-space port for service, not a person-entry body hatch. Confirm placement and sizing against the technical drawing on this page so your inlet, outlet, and vent routing line up with how you intend to plumb the tank before it ships. Because the 18-inch top port is PE-threaded (poly threads, not bolted) and the flange is a gasketed connection, your inlet and outlet seal depends on thread engagement at the port and the gasket or O-ring at the flange — confirm the gasket material suits your liquid before fill. The 18-inch vented top fitting matters on a tall vertical tank like this one: proper venting keeps the tank from drawing a vacuum on rapid draw-down, a detail covered in our guide on HDPE tank wall thickness and ASTM D1998 sizing logic.
Pad, siting, and the mistake to avoid
The single biggest mistake on a vertical tank this size is setting it on a pad that is not flat, full, and properly sized. At 11,251 pounds fully loaded, this tank needs continuous, uniform support across its entire 60 x 60 inch footprint; a tank bearing on a high spot or an unsupported edge concentrates stress and shortens its life. Size the slab using the framework in our guide on concrete pad sizing for above-ground polyethylene tanks. If you are sizing for fire-water reserve or rural standby service, the fire-water reservoir design guide walks through NFPA 22 sizing and freeze protection for cold-climate sites.
One freight reality to plan for: this is a single-plant West Coast tank that ships LTL from the Snyder plant in Chowchilla, California, so freight to the East or Midwest is a real cost line worth quoting before you commit.
