The Snyder Industries 2500 Gallon Vertical Water Storage Tank (SII-WG61) is a green-tinted polyethylene vertical tank built for bulk water storage where you need real volume in a square footprint. It stands 106 inches tall on a 90 x 90 inch base, so a single tank holds 2,500 gallons within a 90-inch diameter. The green color cuts light penetration to slow algae growth in outdoor service, which makes it a common pick for water storage, rural fire reserves, and reuse trains.
Will it work for your install?
This is a 1.0 specific gravity tank, meaning the wall is rated for contents weighing the same as water - exactly the right rating for fresh-water storage and nothing heavier. At full fill, plan for the static load: 2,500 gallons of water weighs 20,850 pounds, and that full-water weight equals the tank's maximum rated contents weight, so the pad and any anchoring you design has to carry roughly 20,850 pounds of contents plus the empty tank. Confirm both the 90-inch square pad footprint and roughly 106 inches of vertical clearance for fill access and any door or roof opening the tank has to pass through. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm this 2,500-gallon size matches your demand, and set it on a level, full-support pad - see our pad-sizing guide on the ACI 360R-10 framework.
Fittings and access
The tank ships with an 18-inch polyethylene manway that includes a 4-inch vent and a factory tie-down provision (ASM MANWAY 18IN PE W/4IN VENT W/TIE). The tie-down retains the lid in wind and transport, and the 4-inch vent is sized to relieve the air exchange as you fill and draw, so you do not pull a vacuum on the tank during draw-down. For plumbing, the 2-inch heavy-duty polypropylene bulkhead with an EPDM gasket is the better choice for the bottom outlet or draw line, and the 1-1/2-inch polypropylene eco-bulkhead with textured EPDM suits a secondary or return line. EPDM is the correct gasket material for water service - just note it is the limiting component if the tank is ever repurposed, which ties back to keeping this on water-weight contents. A separate flange provides a larger-bore connection point versus the threaded bulkheads, useful for a high-flow line or a future accessory tie-in. The exact fitting locations, heights, bore sizes, and the full dimensional layout are shown on the technical drawing on this page - check the drawing against your inlet and outlet plumbing before install. After the tank is set and plumbed, a water-fill acceptance test is worth the time; see our hydrostatic test methodology for fill discipline, pad-settlement monitoring, and fitting leak detection.
One mistake to avoid
This tank is rated to 1.0 specific gravity, so it is built for water and water-weight contents only. Do not put a heavier-than-water liquid in it expecting the same service life - a denser fluid exceeds the wall rating this tank was designed and rated for. For fresh-water duty it is correctly specified; just keep it on water. If you need to store a heavier liquid such as brine, fertilizer, or a chemical above 1.0 specific gravity, call us at 866-418-1777 and we will point you to an industrial-rated tank built for that service gravity. If you are sizing this for a rural fire reserve, our guide on fire-water reservoir design and NFPA 22 sizing covers freeze protection and reserve sizing, and for greywater, rainwater, or HVAC condensate aggregation see our industrial water reuse topology guide.
This tank ships LTL freight from the Snyder plant in Marked Tree, Arkansas, and freight is quoted live to your ZIP. Because LTL rates from Arkansas vary sharply by destination, pull your number early from the Freight Cost Estimator or call us at 866-418-1777. We will help you confirm the right vertical storage tank, the fittings, and the delivered logistics before you commit.
