what is rain water harvesting

Dear Student,

The process by which rain water is collected and stored either to recharge the ground water or for use in the future is known as rainwater harvesting.

The rainwater on the roofs of the buildings is collected through canals that drain the water into ground reservoirs. This stored water is later utilized.

Advantages of  rainwater harvesting :

• it can be undertaken in any type of climate.
• the construction required is quite simple.
• rainwater is usually the purest form of water, so it can be used easily for domestic services.

Hope this helps.

Cheers!
