What is the meaning of rain …

Rainwater which falls on roofs and terraces of buildings can be collected through pipes and stored in underground tanks or can be allowed to percolate into the soil and used to recharge the groundwater table. This is called water harvesting or rainwater harvesting. The main aim of rainwater harvesting is to check the runoff water.

Rainwater Harvesting

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 groundwater, is called rainwater harvesting.

The two main techniques of rainwater harvesting are:

1) Collection and storage of rainwater in tanks for future use when there is scarcity of water, and
2) To make rainwater percolate into the ground more efficiently by constructing percolation pits and recharge wells so as to recharge (or replenish) groundwater.

Rainwater harvesting can be done in two ways:

1) Rooftop rainwater harvesting, and
2) Rainwater harvesting from open spaces around buildings
