What is the meaning of sources of water?


Water is a precious and natural resource on the planet earth. It is found all around us. Nearly two-thirds of the Earth’s surface is filled with water. Every living organism existing on our planet requires water for its survival, including plants, animals, birds, insects, etc.

Water is considered the most precious resource and essential requirement of life. All living things rely on water, and without which, there would be no life.

We humans can survive without food for a day or two, but we cannot stay without drinking water for a short amount of time because our body needs it for different types of life processes.

Uses of Water

We all use water for drinking, cooking, bathing, cleaning, washing, etc. Factories and large industries use water in large quantities for producing various products required for human welfare. Farmers also use water for irrigating and cultivating crops. Thus, water is necessary for many activities; therefore, it is an essential requirement of life.

Sources of Water Meaning

Water is a valuable natural resource found in different forms in our environment.

As per the Earth’s geography, there is a lot of water all around us, but it is not fresh water and not suitable for human use.

The available natural water is not pure forever. Excluding rainwater, all other water sources comprise salts and minerals deposits dissolved in it. These salts make the water impure, which is not fit for consumption.

There are two primary sources of water – surface water and groundwater.

The primary water sources used for drinking, cooking, washing, farming, and other commercial uses are surface water, groundwater, and collected rainwater.

These primary water sources depend on rainfall and snow, which form a part of the hydrological cycle.

Rivers, streams, lakes, and ponds are the main form of surface water. The amount of available surface water depends mainly on rainfall. When rainfall is limited, surface water supply will vary considerably between wet and dry seasons and between years.

Surface water like reservoirs and dams generates hydroelectric power and supplies water for agricultural, municipal, industrial uses, and other commercial purposes.

Rainwater is also an essential water source, although on a relatively small scale. Collecting rain from roofs or other hard-surfaced areas and storing it until it is needed can provide a valuable water source for many purposes.
