The increase in demand for water to meet the ever-expanding human population is a rising concern amongst the environmentalists. As the water from the seas cannot be used for domestic, industrial or agricultural purposes, the need for availability of usable water is now the need of the hour.

To combat the problems due to the shortage of water, harvesting the available water is extremely crucial for any geographical area. Several attempts have already been made to spread the importance of storing rain water and harvesting that to meet various necessities of everyday life. The various importance of rainwater harvesting on daily life and on the environment are discussed here in detail.

What is Rainwater Harvesting?

The process of gathering and accumulating rainwater for future use is known as rainwater harvesting. Generally, water is collected from the household roofs and stored in tanks. This saved water can be later used for various activities and thus reduces the need to rely on commercial water supplies.

Importance of Rainwater Harvesting

Rainwater is a renewable source of water and harvesting rainwater has various domestic, commercial and environmental benefits. Some of the most important benefits of rainwater harvesting are mentioned below.

  • Reduces Dependence on Commercial Water

By harvesting rainwater, one can easily meet most the daily domestic water requirements. Other than drinking, rainwater can also be used for washing, cleaning, etc. Also, commercial businesses can use the harvested water and avoid depleting other natural water sources.

  • Can be Used for Irrigation and Other Agricultural Purposes

As rainwater is free from the unwanted chemicals, the water can be used for irrigation and various other agricultural activities. The stored water can also be used to water plants in the gardens or in the green houses.

  • Helps to Check Floods and Soil Erosion

During rains, the low lying areas get affected due to excess of water overflow. Also, the pesticides get washed due to flowing rain water and those chemicals eventually accumulate in lakes, ponds, etc., thereby causing eutrophication and other water-related issues.

  • Eradicates Water Crisis

Areas without a permanent water source can get rid of water crisis by using rainwater harvesting systems. This stored water can also be used for consumption by humans and livestock with little cleansing and filtering. So, rainwater harvesting is considered as the best solution for the eradication of water crisis.

  • Helps to Reduce Impact on Groundwater

Groundwater has been excessively utilized to meet domestic and commercial needs of the people. Due to heavy extraction, the level of groundwater is depleting exponentially. With rainwater harvesting, the impact on groundwater is reduced to a great extent as the water demand can be met by the stored rainwater.

Due to all these aforementioned advantages, several rainwater harvesting infrastructures has been installed in domestic households and commercial buildings. It is also important to note that the harvesting systems are simple and easy to maintain.

With proper rainwater harvesting, the demand for the world’s water supply can easily be met without depleting the natural sources. As water is the most important resource for every being on this planet, it is suggested to get cautious and implement similar methodologies (rainwater harvesting) to save and preserve the available water sources.
