The Enduraplas 6400 Gallon Vertical Water Storage Tank in black is a large-volume bulk water tank built for site water, irrigation supply, rural fire-water reservoirs, and rainwater or reuse storage — anywhere you need to bank thousands of gallons on a single footprint. This is a 6,400-gallon vertical storage tank standing 150 inches tall on a roughly 120-inch-diameter base, a footprint of about 120 by 120 inches, so size the pad and overhead clearance around those confirmed dimensions. The black wall blocks light transmission, which helps hold back algae growth in tanks that sit outdoors in full sun.
Will it work for my site?
At 6,400 gallons this is one of the larger vertical poly bulk water tanks in its class, and the two things that govern the install are footprint and full weight. The tank occupies a 120 x 120 inch square footprint, stands 150 inches to the top, and filled to capacity with water carries roughly 53,376 pounds — so the foundation is not an afterthought. A tank this size wants a properly sized, level, fully supporting concrete pad. Walk through the load and pad math in our concrete pad sizing guide, and after set, fill, and plumb, run a proper acceptance fill using the hydrostatic test methodology to watch pad settlement and check fittings before the tank goes into service. Sizing a bulk water reserve for a rural or remote site — including fire-water reservoir duty — is covered in our fire-water reservoir design guide, and if you are aggregating grey water, rainwater, or HVAC condensate, see the water reuse tank topology guide.

The mistake to avoid
Underbuilding the foundation. A tank this size is deceptively heavy — empty it moves with a forklift, full it puts more than 53,000 pounds onto a roughly 100-square-foot patch. Any soft spot, slope, or unsupported edge under the pad turns into uneven wall stress once it fills. Size the pad to fully support the entire base and keep it dead level. One more thing worth a phone call before you order: the pack does not lock down the inlet, outlet, and fitting configuration on this tank, so confirm fitting sizes and placement with us at 866-418-1777 so your plumbing plan matches the tank you receive.
Freight
This is a large tank — roughly 120 inches across and 150 inches tall — and it ships LTL freight, quoted live to your ZIP code rather than bundled into the listed price. Get a freight rate for your address with the Freight Cost Estimator, or call us at 866-418-1777 and we will work out the best routing for a tank this size, confirm the delivery site can take a large flatbed, and answer any sizing or pad questions before you order.
