Photo: [http://atlinc.com/pillow.html ATL.]]]__NOTOC__ <small-title />There are numerous brands of portable water tanks that include different shapes, as well. A bladder or pillow tank is square or rectangular-shaped and lies flat on the ground, then rises to look like a "bed pillow" with added water. An onion tank looks like a flexible cup full of water with the top of the tank showing water exposed.
Below are a few commercial tanks to choose from, although note that there are many, many brands available as these are just a few. Below these commercial tanks is information on onion tanks.
