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.
It's an environmentally friendly way of harvesting. ( Using the natural resources that are provided.)

Rain water is collected through a process named Rainwater harvesting. Here rainwater that falls on the roofs are collected through pipes and ultimately stored in large tanks. These are called harvesting tanks also.

Large scale rainwater harvesting is when a river is dammed and the stored water is then used for irrigation, industrial and domestic uses. Small scale rainwater harvesting is when a property owner catches rainfall from a house roof and stores it in rainwater tanks for personal use, including watering, flushing toilets, washing clothes, and bathing, drinking and cooking, if required.
