In the Western world we are very fortunate to have safe, pure water available which is fit for human and animal consumption, this unfortunately is not the case everywhere. Although water, even in remote areas may be available from natural sources such as springs, it may need further treatment before it is fit for human use, this being the case potable water tanks are a necessity.
There are many situations in third world countries where water is consumed in any form it can be found, but as more and more effort is being put into providing people with safe drinking water, aid agencies are purchasing modular potable water tanks and shipping them with compact water treatment equipment to the far corners of the world.
Water which is contaminated is the breeding ground for many preventable diseases and when consumed the people affected may even die. Out of desperation the water which is available is consumed anyway.
Contaminated water can be treated and turned into perfectly good potable water. The simplest of all methods is probably boiling. Boiling might not have any effect on heavy contaminates but it most certainly will kill and bacteria or virus that are in the water, contaminated water can also be chemically treated but these are small solutions for a big problem. One of the biggest problems in these areas is to access potable water tanks which are ideal for storage and distribution.
It is not necessary to live in a third world country to lack access to potable water. Many people are working in remote parts of the country or serving overseas in the military. These people have limited access to almost everything, including large quantities of safe water. In many cases it is possible to find a source of water by drilling a well but this water must be treated to ensure its purity and then stored above ground until needed.
The tanks do not necessarily have to be hard walled tanks, in many cases large bladders which are made from safe materials are the quickest and most economical means of storing water and in some cases, even shipping it over long distances. About the only thing that is necessary potable water tanks is a reasonably flat piece of ground.
