The Enduraplas TC6460IW-BLACK is a 700-gallon vertical water storage tank molded in black polyethylene for outdoor bulk water holding. It stands 60 inches tall on a 65-inch by 65-inch footprint — height and diameter are close to equal, so this is a compact vertical tank rather than a tall column, which makes it a good fit where headroom is limited but slab area is available. Dimensions are launch-verified, so you can lay out your pad and plumbing runs before the tank arrives. It suits general bulk water storage, rural fire-water reserves, and industrial water-reuse trains.
Will it work for your site
Filled to 700 gallons of water this tank carries roughly 5,838 pounds, and that loaded weight — not the empty shell — is what your foundation has to support. Water weighs about 8.34 pounds per gallon, so size the pad for the full-fill number and keep the surface flat and continuous under the entire 65 x 65 base. If you are still confirming the volume you actually need, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. The tank is molded in black per its SKU, and black pigment blocks light through the wall, which discourages algae growth in stored water compared with translucent tanks.
Foundation and install discipline
A vertical poly tank this size needs a properly designed above-ground pad sized to the loaded weight; our guide on concrete pad sizing under the ACI 360R-10 framework walks through getting the base right. Once the tank is set, follow a real acceptance procedure — our hydrostatic test methodology covers water-fill discipline, pad-settlement monitoring, and fitting leak checks so you catch problems before the tank goes into service. If you are building a rural fire reserve, the NFPA 22 sizing and freeze-protection guide is worth a look; if you are aggregating grey-water, rainwater, or HVAC condensate, our water-reuse tank topology guide covers quality-banded storage trains — ask us and we will point you to the right one.
The mistake to avoid
This is a water storage tank. Fitting and outlet configuration is not yet documented for this SKU, so confirm placement with us by phone before you plumb rather than assuming standard positions. And do not size this tank against a chemical service without first confirming the resin and specific-gravity rating with Enduraplas — that rating is not published here, and straight water at a specific gravity of 1.0 is well within intended service, but heavier liquids change the load and the resin requirement entirely.
