Drinking water is the most important food. Because of the importance and of great value, it was decided that this can not be replaced. Drinking water is actually fresh water with such high purity that you can drink it easily. There are several ways to win drinking water. The oldest method is probably the extraction of drinking water by using wells. The shallow groundwater was obtained with single walled shaft well. Here we used a bucket and a winch to pull the water from the well. Sources are still used today for drinking water supply. When you talk about sources said one that emerges from a source of water, the groundwater naturally.
