Which are the two types of rainwater harvesting?

Answer 1

There are two types or rainwater haversting. Rooftop rainwater harvesting and drain harvesting.

In rooftop rainwater harvesting, we use the water collected on rooftops instead of letting it go down the drain. We can also use water collected in dugout ponds, underground vessels etc.

Drain harvesting involves letting water collected in roadside drains go straight to the ground. But this water has to be treated before use as it may contain bird faeces, germs and other pollutants.

Answer 2

The two main types of rainwater harvesting are rooftop rainwater harvesting and surface runoff harvesting. Rooftop rainwater harvesting involves collecting rainwater from roofs and storing it for future use. Surface runoff harvesting involves collecting rainwater from surfaces like roads or open fields to recharge groundwater or for other uses.
