The Enduraplas TC1500IW-BLACK is a 1,500-gallon vertical water storage tank built for bulk and utility water where you need real volume in a compact footprint. It stands 126 inches tall on a 64 x 64 inch base, so it holds a full 1,500 gallons while occupying just over five feet of floor in each direction. The black exterior blocks light penetration, which slows algae growth in stored water compared to translucent tanks. If you are matching tank volume to daily demand or drawdown-and-refill cycles, run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a size. This is a standard search match for a 1500 gallon vertical water tank or 1500 gallon black poly storage tank.
Will it work for your site
Filled to capacity, this tank carries 12,510 pounds of water. That load lands on a 64 x 64 inch footprint, roughly 4,096 square inches, which works out to about 3 psi of bearing pressure or near 440 pounds per square foot on the pad below. That pad has to be engineered to carry the load flat and stay flat over time, because a vertical poly tank this tall does not tolerate an out-of-level or settling base. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting the foundation right, and once the tank is set, the hydrostatic test methodology for new-install acceptance covers the water-fill and settlement-monitoring discipline that proves the install before you rely on it. For rural fire-protection reservoirs and industrial water-reuse trains, see our writeups on NFPA 22 fire-water reservoir sizing and reuse-capable bulk water topology to place this tank in the larger system.
The mistake to avoid
This is a water storage tank. Do not put it into chemical service on the assumption that any poly tank handles any liquid. Chemical duty depends on the resin and the specific-gravity rating of the tank, and that rating is not stated for this unit, so confirm the tank's specific-gravity rating with us before storing anything heavier than water. A full column of water 126 inches tall produces roughly 4.5 psi of static head at the base, so size the outlet plumbing and any valves for that pressure. Confirm the fitting and outlet locations against the technical drawing on this page before you pour the pad or order plumbing. Fitting sizes are not yet listed on this page, so call us to confirm the inlet and outlet configuration for your build rather than assuming a spec.
