Snyder Industries 6900 Gallon Open Top Containment Tank 1.9 S.G. (VOT)

The Snyder Industries 6900 Gallon Open Top Containment Tank is a cylindrical, open-top vessel molded in white High Density Linear Polyethylene and rated to a 1.9 specific gravity. It stands 145.6 inches tall on a 120 x 120 inch footprint - a full 10-foot square pad - which makes it a heavy-duty open top containment tank for secondary containment, batch mixing, and bulk water or process holding where crews need top access for a mixer, a fill line, or manual charging. When you are matching a tank to a job, the rated specific gravity and the maximum contents weight are the two numbers to check against your liquid.

Will it work for your job?

Filled with plain water this tank holds about 57,546 lb of contents, and the shell is rated to a maximum contents weight of 109,337 lb at its 1.9 specific-gravity limit. That spread is the headroom for holding denser liquids up to the stated rating without exceeding the wall design. The 1.9 S.G. figure is a flat rating, not a chemical clearance - this is a water and process open tank, so confirm any specific liquid before service. Use the specs below and the technical drawing on this page to size your berm and clearance, then run your volumes through our Tank Sizing Calculator and Tank Sizing Guide.

• Capacity: 6,900 gallons, white HDLPE, 1.9 S.G. rated
• Dimensions: 145.6 in tall, 120 x 120 in footprint
• Full water weight: 57,546 lb - Max rated contents: 109,337 lb

Fittings and pad

This is an open-top tank with no molded lid or factory fitting schedule, so every penetration is a field-added bulkhead fitting. Each bulkhead needs a compatible gasket or O-ring sized to the wall thickness - confirm bulkhead and gasket compatibility before you drill, and call 866-418-1777 to spec them with us. On the foundation side, an open top containment tank this size lives or dies on its pad: at better than 57,000 lb of water alone, set it on a level, continuously supported base sized for the full contents load. Our guide to concrete pad sizing for above-ground polyethylene tanks walks the ACI framework, and if this is a transfer or loadout point, see loadout pad engineering for bulk polyethylene tanks. For fire reserve or reuse duty, our notes on fire-water reservoir tank design and industrial water reuse tank topology cover the wider system.
