How to choose a portable water tank

  1. Size it to one load. The tanks here are Chem-Tainer horizontal leg tanks in 30 and 125 gallon sizes. Work out how much water, fertilizer or chemical you need to hold or move at one time, and pick the size that covers it.
  2. Measure where it will sit. A horizontal tank lies on its side on legs, so check its length and width as well as its height against the truck bed, trailer deck or floor space you have. The product page lists its dimensions.
  3. Add up the full weight. Water weighs about 8.34 pounds per gallon, and the tank's own empty weight, listed on its product page, comes on top. Make sure whatever carries the tank is rated for the total.
  4. Step up to another type for more volume. Past 125 gallons, compare vertical water storage tanks or pillow water tanks, or browse water tank capacities for common sizes from 500 to 5000 gallons.

Portable water tank questions

What is a horizontal leg tank? It is a tank that lies on its side and stands on legs, which keeps its weight low and the tank steady while it is stored or hauled. Chem-Tainer makes the 30 and 125 gallon models in this category for water, fertilizers and chemicals.

How do I work out how many gallons I need? If you are matching an existing tank, the tank volume calculator turns its shape and dimensions into gallons, and a fill depth gives the current volume. Treat the result as a geometric estimate: wall thickness, fittings and freeboard can make usable capacity differ.

Can I use a portable tank for livestock water? For herds that follow the grass, the portable stock water tank guide covers folding frame tanks with an aluminum or steel frame and a vinyl or high-performance rubber liner, which assemble and come apart quickly. It also covers lightweight plastic stock tanks made from UV-resistant polyethylene.

What can I use as a temporary holding tank? Pillow tanks, also called collapsible bladder tanks, give flexible water storage at almost any location. They can hold drinking water, grey water or fuel, with the fabric matched to the liquid, so name the liquid you plan to store when you choose one.
