The Snyder Industries 6200 Gallon Plastic Vertical Liquid Storage Tank (SKU SII-8220000C37) is a white polyethylene vertical storage tank built for high-volume water and liquid storage where you need real bulk capacity in a single vessel. At 6,200 gallons it stands 140 inches tall on a 120 x 120 inch footprint, and it carries a 1.5 specific gravity rating, so it is engineered to hold liquids up to 1.5 times the weight of water. For a private fire-water reservoir, agricultural and irrigation supply, rainwater capture, or general bulk water storage, this is the kind of vertical tank that anchors the system.
Will it work for your site?
Plan around the numbers. Full of water this tank weighs roughly 51,708 lb, and at its maximum 1.5 SG rating it can carry contents up to 77,562 lb. The 1.5 specific gravity rating is your service ceiling: this tank handles liquids up to 1.5 times the density of water, which covers water, brine, and many solutions, but verify your liquid's specific gravity against 1.5 before you fill it. If your fluid is heavier than 1.5 SG, you need a higher-rated vessel, not this one. That maximum load is also a serious point load: spread 77,562 lb across a 120 x 120 inch footprint and you are putting roughly 5.4 lb per square inch (about 776 lb per square foot) onto a single pad. Hand that figure to whoever pours your slab. Before you set this tank, work through our concrete pad sizing guide so the foundation carries the load and keeps the tank level and fully supported. If you are still confirming capacity for your draw-down or reserve volume, the Tank Sizing Calculator and Tank Sizing Guide will help you match the 6,200 gallon size to your demand.
Fittings and the technical drawing
For exact fitting locations, outlet and bulkhead sizes, lid placement, and overall tank dimensions, see the technical drawing on this page. The drawing is the authoritative reference for outlet and fitting placement on this vertical storage tank, so confirm those details against your plumbing layout before you order valves, bulkhead fittings, or gaskets, and before you pour your pad. If you have questions about how this tank is outfitted, call 866-418-1777 and we will walk through it with you.
Sizing it into a larger system
A 6,200 gallon vertical tank often does its best work as one element in a larger storage stack. If you are designing rural or remote fire protection, our guide on fire-water reservoir tank design covers NFPA 22 sizing discipline, and in cold climates a fire reserve needs real freeze protection so the stored volume stays available when it is called on. For reuse projects, the industrial water reuse tank topology guide shows how grey-water, rainwater, and condensate aggregation come together in quality-banded storage trains. And because failures in polyethylene tanks often originate at the vapor-saturated headspace above the liquid line rather than on the liquid side where inspections focus, the guide on HDPE tank wall thickness and ASTM D1998 sizing logic is worth reading before this tank goes into long-term service.
This tank ships LTL freight from Snyder's plant in Marked Tree, Arkansas, with freight quoted live to your ZIP. At 140 inches tall this is an oversize load, so expect flatbed handling and plan for delivery access at your site before the truck arrives. Use our Freight Cost Estimator for a freight estimate to your delivery address, or call 866-418-1777 and we will price the freight and help you set up delivery for a tank this size. A 6,200 gallon vertical storage tank is a major install, and we will make sure it arrives ready to set.
