The Bushman 3100 Gallon Vertical Water Storage Tank in green is a large-footprint polyethylene tank built for bulk water storage, rainwater capture, irrigation supply, and rural fire-protection reserves. It holds 3,100 gallons in a vertical, above-ground body measuring 102 inches in diameter and 99 inches tall, so it fits a compact 102 x 102 inch pad while still banking three thousand-plus gallons. The verified dimensions, along with fitting sizes and placement, are shown on the technical drawing on this page.
Will this tank work for your site?
Start with the numbers. This is a 3100-gallon vertical bulk water tank with a 102-inch round footprint and a 99-inch overall height. Here is the detail that kills more deliveries than any other on a tank this size: it is wider than it is tall, so the 102-inch diameter, not the 99-inch height, is the binding constraint. Measure your gate width and every doorway on the delivery path before you order. Filled to capacity, the tank and water together weigh roughly 25,854 pounds, which is why the pad underneath matters as much as the tank itself. A flat, fully supporting, level base rated for that full-water load is required; a partial or settling pad concentrates stress on the tank wall. If you are still deciding between this size and a smaller or larger vessel, run your daily demand and drawdown through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit.
Pad and install
The foundation is the single most important part of an install this large. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for a base that carries the full 25,854-pound water load without cracking or tilting. Once the tank is set and plumbed, use our hydrostatic test methodology to fill in stages, watch for pad settlement, and check fittings before the tank goes into service. For rural fire-reserve duty, the NFPA 22 reservoir design guide covers sizing discipline and freeze protection, and the water-reuse topology guide helps if you are aggregating rainwater or grey-water into a banked storage train.
The mistake to avoid
The most common error on a tank this large is treating it like a smaller poly tank on install day. A 3100-gallon vertical tank cannot sit on gravel, pavers, or an undersized slab; the full-water load will find any weak spot in the base. Get the pad right first, then fill and test in stages.
