The Chem-Tainer 4500 Gallon Vertical Storage Tank is a large-capacity polyethylene vessel built for bulk water and liquid storage where you need serious volume in a stable, single-footprint tank. It stands 156 inches tall on a 95-inch diameter with a 95 x 95 inch footprint, is molded in Natural White polyethylene, and carries a 1.5 specific gravity rating. That combination makes it a workhorse for water reserves, rainwater and process-water storage, fire-water reservoirs, and industrial water reuse programs.
Will this vertical storage tank work for your site?
Start with the number that governs your foundation: filled with water, this tank weighs roughly 37,530 lb. That full-water weight, spread across the 95-inch diameter footprint, is the load your pad has to carry for water service, so design the slab to it. A vertical tank of this size and 156-inch height needs a level, engineered pad, and because water has a specific gravity of 1.0 this tank sits well inside its 1.5 rating. Before you pour, read our concrete pad sizing guide, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm 4,500 gallons matches your draw and refill cycle. Check the technical drawing on this page for fitting locations and overall geometry before you set the tank.
What the 1.5 specific gravity rating means
The 1.5 specific gravity rating is the maximum liquid density this wall thickness is engineered to hold, which works out to a contents ceiling of 56,295 lb. For a water application you will not approach that number, so treat it as headroom and reassurance rather than a figure to build to; your governing load stays the ~37,530 lb full-water weight. That margin is why this white vertical storage tank suits water reserves, rainwater capture, HVAC condensate aggregation, and grey-water reuse trains. The most common mistake on a tank this size is mismatching the pad to the real operating load, so anchor your foundation to the liquid you will actually store. If you are planning a private fire-protection reserve, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection, and the industrial water reuse topology guide walks through quality-banded storage trains.
Freight on a tank this size
This 4,500 gallon vertical tank ships LTL freight from the Chem-Tainer plant in Hummelstown, PA, with the exact cost quoted live to your ZIP code. At 156 inches tall it moves as an oversized freight item, so confirm delivery access and offload equipment before you order. Get a real number from our Freight Cost Estimator, or call us at 866-418-1777 and we will quote the freight and confirm lead time.
