The Chem-Tainer 4500 Gallon Green Vertical Water Storage Tank is a polyethylene vertical water tank built for high-volume bulk water storage, holding 4,500 gallons on a 95-inch-diameter footprint that stands 156 inches tall. If you are sizing a single large reservoir for irrigation, fire-water reserve, or rural water hauling, this is the kind of vertical storage tank that consolidates a lot of capacity onto one pad. Here is what it does, how it ships, and the one number that decides whether your foundation is ready for it.
What this tank does
This is a 4,500-gallon vertical water tank molded from polyethylene, finished in green, measuring 156 in tall by 95 in diameter. It carries a specific gravity rating of 1.0, which means it is engineered for water and water-density contents - it is a water storage tank, not a chemical tank. The vertical design and 95.0 x 95.0 inch footprint give you maximum gallons per square foot of ground, which matters when pad space is the constraint. Fitting size, outlet placement, and dimensional callouts are detailed on the technical drawing on this page and confirmed at order, so check those exact locations against your plumbing before you set the tank.
Plan your pad before it arrives
The number to engineer around is weight. Filled to 4,500 gallons of water, this tank and its contents reach 37,530 pounds - that full water weight is also its maximum rated contents weight. That is over 18 tons concentrated on a 95 x 95 inch base, so the supporting surface has to carry it without settling or cracking. A flat, fully supported, level pad is not optional at this size. Use our Tank Sizing Calculator and Tank Sizing Guide to confirm the capacity fits your draw, and read our guide on concrete pad sizing for above-ground polyethylene tanks for the ACI 360R-10 framework that governs a foundation under this kind of load.
The mistake to avoid
The most common error on a tank this large is treating the SG 1.0 rating as a license to store anything liquid. It is not. A 1.0-rated wall is sized for water at roughly 8.34 pounds per gallon; fill it with a denser fluid and you raise the hydrostatic load on that wall proportionally the moment it is filled. Keep it on water service - bulk water storage, rainwater capture, fire-water reserve, or hauled supply - and it will do the job it was molded for. If you are weighing this against other brands at large vertical sizes, our Snyder vs Norwesco vs Chem-Tainer vertical storage tank comparison walks through the differences. For reuse setups blending grey-water, rainwater, or HVAC condensate into banded storage trains, see our industrial water reuse tank topology guide, and for rural fire protection planning, our fire-water reservoir design guide covers NFPA 22 sizing discipline.
This tank ships LTL freight from our plant in Hummelstown, PA, with the cost quoted live to your ZIP code. At 95 inches wide and 156 inches tall it sits outside a standard freight envelope, so plan on flatbed or oversize handling and customer-side offload equipment such as a forklift or crane. Get your number from our Freight Cost Estimator or call 866-418-1777 and we will walk you through delivery, offload, and siting for a tank this size.
