The 200 Gallon Plastic Vertical Water Storage Tank in green (Snyder Industries part SII-32495) is a polyethylene vertical water storage tank sized for homes, farms, and jobsites that need a compact 200-gallon reserve. It stands 42 inches tall on a 40 x 40 inch footprint, so it fits through most gates and into tight equipment sheds while still holding a full 200 gallons of water. If you are shopping vertical storage tanks and want a straightforward 200 gallon tank for water storage, hauling, or gravity feed, this is the size that anchors a small storage train.
Will it work for your site?
This tank carries a specific gravity rating of 1.0, which covers water and water-thin liquids at that density. Filled to capacity the water alone weighs about 1,668 pounds, and the tank is rated to a maximum contents weight of 1,668 pounds, confirming it is a water-only design. That 1,668 pounds sitting on a 40 x 40 inch base works out to roughly 1.04 pounds per square inch of bearing load, so the pad underneath is the part most people underestimate. Run your reserve size through our Tank Sizing Calculator and the Tank Sizing Guide, then size the slab with our guide on concrete pad sizing for above-ground polyethylene tanks before you set it in place.
Fittings and plumbing
Inlet, outlet, bulkhead, and lid locations are shown on the technical drawing on this page. Before you order, call 866-418-1777 to confirm the thread type and gasket material against your existing plumbing so you are not adapting fittings on install day. Whichever connections you run, set the tank on a level, fully supporting pad first: a full tank on soft or uneven ground can settle and stress those fitting connections.
The mistake to avoid
The 1.0 specific gravity rating is a real limit, not a formality. Water storage is exactly what this tank is built for, but if your plan later shifts toward a heavier liquid, that density figure is the signal to step up. Call 866-418-1777 and we will point you to a higher-SG-rated tank in this size rather than pushing this one past what it is built for. For a straight water reserve, commission the tank properly: our hydrostatic test methodology guide walks through the water-fill and pad-settlement checks that catch problems before the tank is in service.
Freight
This tank ships by LTL freight, quoted live to your ZIP code, from the nearest Snyder Industries plant. Fulfillment for the green 200-gallon runs from Merced, California, with Albertville, Alabama also in the network, and the Freight Estimator resolves the exact origin for your address. Freight on a tank this size is priced by destination and pallet class, so get an exact number with our Freight Cost Estimator or call 866-418-1777 and we will quote it for you.
