    The activity of collecting rainwater directly and store it in big tanks for later use, or making the rainwater percolate into ground more efficiently to recharge the ground water, is called rainwater harvesting.

     

    Rainwater harvesting can be done in two ways:

    1. Rooftop rainwater harvesting: In this method, the rainwater is collected from the rooftop to a storage tank through pipes. This water may contain soil particles from the roof and needs to be filtered before use. Instead of collecting rainwater in the tank, the pipes can go directly into the percolation pit in the ground. The water seeps into the soil to recharge or refill the ground water.
    2. Rainwater harvesting from open spaces around buildings. Rainwater goes into the ground directly from the roadside.
