Water supply

An image of water referring to the supply of water

In the ancient times, a nomadic person kept moving in the search of pastures and water. Even in present days, they kept moving with their cattle in the search of food and water. Probably rivers and fountains were the first resource of water. Slowly, humans started making small villages near the water. Where people used the skulls of animals or leather bags to drink water. When these fountains and rivers started to dry because of the continuous use of water, humans started finding more resources for water. Finally, humans learned that there is some water under the ground. Which can be taken out by digging a hole. And that’s how humans reached to the water under the ground by digging big holes in the ground. It means that humans learned to make wells. Later, humans learned new things from which they could get a permanent resource of water, they started making dams and started storing water. In the first cities of the earth, they made open ponds to store rain water. And like this, when they ran out of water present on surface they used the rain water they stored before. And till now the areas where is deficiency of water, they use this technique.

Whether the supply of water is on large scale or on small scale, there must be a source for that. This source can either be a fountain, any river or a well. In the ancient times, there were drains to supply water over long distances. While today big pipes are used for this purpose.
