The Enduraplas 1150 Gallon Vertical Water Storage Tank (SKU TC1150IW-NATURAL) is a bulk polyethylene tank built for stationary above-ground water storage. It stands 156 inches tall on a 48-inch by 48-inch footprint, so the full 1,150-gallon volume sits on a compact four-foot square pad instead of sprawling across your site. The dimensions on this listing are verified, so you can lay out your pad with confidence before the tank arrives.
Will it work for your site?
Vertical storage tanks are sized by two numbers: the volume you need and the load that volume puts on the ground. Filled to capacity with water, this tank carries roughly 9,591 pounds over its 48 x 48-inch footprint, and that figure drives your pad decision more than the gallon count does. Pour the base for the filled weight first, then confirm the tank. Our Tank Sizing Guide and Tank Sizing Calculator help you check the 1,150-gallon size against your real draw and refill cycle, and the guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for a load of this size.
The mistake to avoid
At 156 inches of fill height on a 48-inch base, this tank has a tall 3.25-to-1 aspect ratio, and the most common misstep is setting it on an under-built or unlevel pad. An uneven base puts uneven wall loading on the shell and can let a tank this tall rock as levels change. Cure a level, load-rated pad sized for the filled weight before delivery, then prove the install with a water-fill acceptance test. Our writeup on hydrostatic test methodology for new-install acceptance covers fill discipline, settlement monitoring, fitting leak detection, and hold-time math. If this tank is headed for a rural fire-protection or reuse role, the fire-water reservoir design guide and the industrial water reuse topology guide put the sizing in context. Check the fitting layout on the technical drawing on this page against your plumbing plan before you order.
Freight
This tank ships LTL freight on its own. Because it's a large poly tank, freight is quoted live to your delivery ZIP rather than baked into the list price. Get your number in seconds with the Freight Cost Estimator, or call 866-418-1777 and we'll quote the lane and confirm pad and offload details for the 1,150-gallon size before you order.
