4000 Gallon ChemTainer Plastic Water Storage Tank in White

The 4000 Gallon ChemTainer Plastic Water Storage Tank in white is a vertical polyethylene tank built for high-volume bulk water storage where a large, stable footprint matters. It stands 125 inches tall on a 102 by 102 inch base, so you get 4,000 gallons of capacity without an oversized pad. The white shell lets you read the fill level at a glance in outdoor bulk-water, agricultural, and rural fire-reserve service.

Will it work for your site?

This is a 4,000-gallon vertical storage tank measuring 102 inches wide by 102 inches long by 125 inches tall. Plan your slab to the full 102 by 102 inch footprint. Filled with water it carries a working load of 33,360 pounds, so the pad has to be sized and reinforced for that mass concentrated on a square base. Our concrete pad sizing guide walks the ACI 360R-10 framework for above-ground poly tanks, and the hydrostatic test methodology guide covers the water-fill and settlement-monitoring steps for accepting a new install. If you are still matching gallons to demand, the Tank Sizing Calculator and Tank Sizing Guide help you size before you commit.

Sizing and use

At 4,000 gallons this tank suits bulk water storage, water-hauling reserves, irrigation supply, and rural or remote fire-water reservoirs. For private fire-protection reserves, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. Running a water-reuse or rainwater aggregation train? The industrial water reuse topology guide maps how a tank this size fits a quality-banded storage stack. Confirm outlet, bulkhead, and vent locations against the technical drawing on this page before you finalize plumbing and tie-in points, or call 866-418-1777 if you need the fitting configuration verified.

The mistake to avoid

Do not treat this as a drop-and-fill unit. A tall vertical tank loaded to 33,360 pounds is unforgiving of an under-built or unlevel pad — settlement on one corner of the 102-inch square base is the most common cause of stress cracking near the base knuckle. Get the slab flat, level, rated for the full water weight, and supporting the entire footprint. This tank is configured for water storage; size and set it as a water tank and it will do that job for decades.
