3. 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.
