Answer 1

Answer: (A), (C)

The correct options are
A

to conserve rainwater for different uses

C

to increase groundwater level

Rainwater harvesting can be done for groundwater refilling or for conserving water for day-to-day use. During days of heavy rainfall, excess water from rooftops can be guided via pipes to be stored in tanks or reservoirs for future use when there is less or no rain or can be made to seep through grounds to increase the underground water level.
