The Snyder Industries 550 Gallon Vertical Water Storage Tank in green is a polyethylene vertical tank built for above-ground bulk water storage on a 64-inch square footprint, standing 46 inches tall. It holds 550 gallons of water and carries a 1.0 specific gravity rating, which means it is engineered for water and water-weight liquids - the kind of straightforward vertical storage tank that handles irrigation, livestock, rainwater holding, and rural fire-water reserves.
Will it work for your site?
Filled to capacity, this tank carries 4,587 pounds of water - that is the full-water weight and also the maximum rated contents weight, so plan your pad and base for the full load. The footprint is 64.0 x 64.0 inches, square and stable, which keeps pad layout simple. Because the 1.0 SG rating is matched to water at standard density, keep this tank in water service; if your liquid is heavier than water you would need a tank rated to a higher specific gravity - run that decision through the Tank Sizing Guide before you order. Work your volume and refill math through the Tank Sizing Calculator too, so you confirm 550 gallons is the right capacity for your draw.
Fittings, access, and wetted materials
The tank comes configured with an 18-inch polyethylene manway assembly that includes an integral 4-inch vent and a tie-down provision (ASM MANWAY 18IN PE W/4IN VENT W/TIE SII). The 4-inch vent gives you top-side venting as the tank fills and draws down - keep it clear, and size your pumped fill and discharge rates so they do not outpace what a 4-inch vent can pass, which prevents pressure or vacuum building in the tank. The tie-down provision gives you a defined anchoring point for wind and uplift, which matters for an empty poly tank at this 64x64 footprint. For plumbing, the tank carries a 1-1/2-inch and a 2-inch bulkhead outlet, both polypropylene bodies with EPDM gaskets - match your supply and discharge line sizes to those two connections before ordering adapters. The PP body plus EPDM gasket combination is standard for water service; check your specific fluid against EPDM if you are running anything beyond plain water. The tank also includes a 9-inch x 10-inch flat fitting pad and a flange location for additional connections.
Install and acceptance
A square poly tank of this size sits on a properly sized, level pad - size it for the full 4,587-pound load using the ACI 360R-10 pad-sizing framework. After setting the tank, a controlled water-fill acceptance test will flush any pad-settlement or fitting-leak issues before the tank goes into service - the hydrostatic test methodology guide walks through fill discipline and hold-time math. For exact fitting positions and elevations, see the technical drawing on this page and confirm placement against your inlet and outlet plumbing before install. If this unit is feeding a rural fire reserve, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection, and reuse trains aggregating grey-water, rainwater, or HVAC condensate are covered in the water-reuse tank topology guide.
This Snyder vertical water storage tank ships LTL from the Snyder plant in Marked Tree, Arkansas. Because it is freight, your cost depends on your delivery ZIP and accessorials - get a live number on the Freight Cost Estimator or call us at 866-418-1777 and we will quote it to your address. The most common mistake on a tank this size is under-building the pad: size it for the full 4,587 pounds before delivery so the tank lands level and ready to fill.
