Answer:
Rain water's most well-known and most important effect is providing you with water to drink. ... Less than 2 percent of the earth's water is ground water, but it provides 30 percent of our fresh water. Without rain water's continued replenishment of the water table, potable water would become scarcer than it already is. Rainwater harvesting is a type of harvest in which the rain drops are collected and stored for the future use, rather than allowing them to run off. Rainwater can be collected from rivers or roofs and redirected to a deep pit (well, shaft, or borehole), aquifer, a reservoir with percolation, or collected from dew or fog with nets or other tools. Its uses include water for gardens, livestock,[1] irrigation, domestic use with proper treatment, indoor heating for houses, etc. The harvested water can also be used as drinking water, longer-term storage, and for other purposes such as groundwater recharge.
