Answer 1

Rain water harvesting is the collection of rainwater into the man made resources or any natural resource like pond, lake, etc at the same place where it falls from rooftops or ground. Two main techniques of rainwater harvesting are storage for future use and recharge into the ground. It can be used for crop harvesting, gardening, toilets, etc. Following are the benefits of rainwater harvesting at individual or city-wide level:

It helps in reducing the water supply bills especially to the institutions.

Rainwater recharged to the ground positively affects groundwater quality by diluting fluorides, nitrates and its salinity.

It contains almost neutral pH and zero hardness which makes it more able to be used in homes, industries, institutions and other commercial establishments.

It may reduce the stress of public water supply sources.

Recharge of rainwater to the ground prevents sea-water immersion into the fresh water bodies in the coastal areas.

It helps in controlling urban flooding if people do rainwater harvesting from rooftops.

It reduces water demands of people from the municipality thus lessens energy consumption too in distributing water all through the city

Answer 2

Answer:-

Rainwater Harvesting is a technique of collecting rainwater. When it rains, most of the water goes unused flowing into water bodies. Through rainwater harvesting the rainwater is collected and stored in artificial or natural water reservoirs for future use. This stored water can be used in farming, domestic use, etc.

This water can also be used at home after purifying it.
