The Enduraplas 1100 Gallon Vertical Water Storage Tank (SKU 901100-1.2-NAT) is a free-standing polyethylene tank for bulk water, rainwater, fire-reserve, and general liquid storage on farms, job sites, and remote properties. Before you order, pull up the dimensions and footprint listed on this page and confirm the tank fits your pad, containment area, or trailer deck — a vertical tank with a flat bottom wants a fully supported, level base under the entire tank, not a ring or a set of blocks. If the tank measurements on this page don't square with your space, call 866-418-1777 and we'll confirm the exact footprint and height for this SKU before anything ships.
Will it work for your site
At 1100 gallons, a full tank of water weighs about 9,174 pounds, so the ground underneath has to carry roughly four and a half tons. That single number drives the whole install: pour or compact a pad rated for the load, keep it dead level across the full footprint, and plan clearance for your valve and hose run. If you are still deciding on capacity, run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide so the tank matches your draw-down and refill cycle instead of guessing high.
Fittings and service class
Fitting configuration is not published for this SKU, so treat it as a call-to-confirm rather than an omission — dial 866-418-1777 to verify inlet, outlet, and lid sizes before you order plumbing. This tank is specified for water service; the published specs here cover water. If it will ever hold anything heavier than water, verify the specific gravity rating for your chemical before you fill it, because a liquid denser than water changes the load on the wall and floor.
Common mistake to avoid
The most frequent error on a tank this size is treating it like a lighter poly tank and skimping on the base. A vertical water tank transfers nearly its entire filled weight straight down through the floor, so any soft spot, void, or slope under the bottom becomes a stress point over time. Support the full footprint. For fire-reserve installs, our NFPA 22 reservoir design guide covers sizing discipline and freeze protection, and the water-reuse topology guide covers rainwater and grey-water aggregation trains built around bulk poly storage.
