The Enduraplas TC6400IW-GREEN is a 6,400-gallon vertical polyethylene water storage tank built for high-volume bulk holding — fire-water reserves, irrigation supply, process-water buffering, and reuse trains. It stands 150 inches tall on a 120-inch diameter, so it holds serious volume without sprawling across the yard. If you are sizing a large above-ground poly water tank or searching for a 6400 gallon vertical storage tank, this is the tank the spec sheet points to.
Will it work for your site?
Here are the numbers that drive the decision:
- Capacity: 6,400 gallons
- Diameter: 120 in
- Height: 150 in
- Full water weight: 53,376 lb
- Minimum pad footprint: 120 x 120 in
Full of water, the tank and its contents weigh roughly 53,376 lb, so the pad underneath it has to be engineered for that load — not an afterthought. Plan a level, load-rated foundation sized to at least the 120 x 120-inch footprint before the tank ever ships. Our concrete pad sizing guide walks the ACI 360R-10 framework for above-ground poly tanks, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 6,400 gallons is the right band for your draw and refill cycle. If this reservoir feeds a private fire-protection system, our NFPA 22 reservoir design guide covers the sizing discipline behind rural and remote fire-water storage.
Commissioning and reuse
A tank this size earns a proper acceptance test. Before you put it in service, fill it slowly on water, watch the pad for settlement, and check every fitting for leaks over a measured hold time — the method is laid out in our hydrostatic test methodology. If the tank anchors a grey-water, rainwater, or HVAC-condensate aggregation scheme, our water reuse topology guide shows where a bulk poly tank fits in a quality-banded storage train.
The mistake to avoid
This is a water tank. The green polyethylene body is specified for water service — do not put chemical or high-specific-gravity liquid in it without matching the tank to that duty. Heavier-than-water fluids and chemical exposure demand a tank rated for the specific gravity and chemistry involved, and that is a different tank. Keep this one on water and it will do exactly what its spec sheet promises. See the technical drawing on this page for the confirmed dimensional layout before you set your pad and plumbing.
