Why do we need to save water ?

Water conservation means using our water wisely and caring for it properly. Since each of us depends on water for life, it is our responsibility to learn more about water conservation and how we can help keep our water pure and safe for generations to come. Since we all enjoy the benefits of having pure, clean water, we must 

help conserve water so that we may continue to enjoy these benefits.

Rainwater harvesting provides an independent water supply during regional water restrictions and in

developed countries is often used to supplement the main supply. It provides water when there is a drought, prevents flooding of low-lying areas,

replenishes the ground water level, and enables dug wells and bore wells to yield in a sustained manner.

It also helps in the availability of clean water by reducing the salinity and the presence of iron salts.
