The Chem-Tainer 4000 Gallon Vertical Storage Tank is a full-size bulk water storage vessel molded in natural white polyethylene, standing 140 inches tall on a 95-by-95-inch round footprint. If you are staging fire-protection reserve, hauling in water supply for a rural site, or aggregating rainwater and process water at volume, this is the size that carries a farm, ranch, or remote facility through a long dry stretch without a refill run.
Will it hold what you need
At 4,000 gallons, a full load of plain water weighs about 33,360 pounds. That is the number to plan your pad around, not the empty tank. This vertical storage tank is also rated for contents up to 1.5 specific gravity, so it handles fluids heavier than water at up to 50,040 pounds of rated contents, versus 33,360 pounds for plain water. The natural white wall lets you read the water line at a glance, which matters when you are managing a reserve you cannot afford to run dry. The straight-wall vertical design drains and cleans predictably and sits flat on a properly prepared base. Before you set it, run your volume and drawdown through the Tank Sizing Calculator and the Tank Sizing Guide so the tank matches your actual demand instead of a guess.
The pad is the whole job
A tank this size lives or dies on its foundation. With more than 16 tons of water bearing down on a 95-inch circle when full, the base has to be flat, level, and continuously supported edge to edge. At 95 inches in diameter and 140 inches tall, size your pad to fully support that 95-inch circle. For the exact height and diameter, see the technical drawing on this page. For the engineering behind a slab that holds this load, read our guide on concrete pad sizing for above-ground polyethylene tanks. The most common and most expensive mistake at this scale is setting a full tank on an undersized or uneven pad and cracking the foundation, or worse, stressing the tank wall. Call us to confirm outlet and fitting configuration for your setup before you order.
Fire reserve and water reuse duty
Many buyers at 4,000 gallons are building a private fire-protection reserve or a reuse train. If that is you, our guide on fire-water reservoir tank design for rural and remote sites walks the NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, and HVAC condensate aggregation, see our breakdown of industrial water reuse tank topology. Comparing brands at the vertical-storage size?
