Essay On Rainwater Harvesting For Students In Easy Words – Read Here

Introduction:

For the last ten-fifteen years, the name of rain-water harvesting has often been heard in the backdrop of the water crisis. For the last few years, the government is also making continuous efforts to promote this work.

Rainwater harvesting, this word directly means the conservation of rainwater. Today in this essay we will talk about rainwater harvesting.

The Problem Of The Water Crisis 

Today, the water crisis is increasing rapidly around the world. Experts say that if conditions do not improve, 50 percent of the world’s population will be forced to face severe water scarcity. Rainwater harvesting is the most effective way to deal with water scarcity.

What is Rainwater Harvesting? 

Rainwater harvesting is the process of collecting rainwater from falling surfaces and then collecting it for future use. Typically, water is collected from the roof and stored in a tank.

It can also be stored in dams or cause it to fall to the ground, causing a runoff. Rainwater harvesting is a sustainable, economical and safe source of good quality water when collected and stored correctly.

The Surfaces Water Collection System

Surface water collection systems enable the collection of ground surface rainfall before it flows to other locations. Examples of such systems include rivers, ponds, and wells. Drainage pipes can be used to direct water into these systems.

Roof System

The roof system can also be used for rainwater harvesting. It can be used to direct let the rainwater to the roof of a building in containers or tanks. These tanks are usually elevated, when the tap is opened, the water flows under high pressure.

This method of rainwater harvesting is good because the accumulated water is mostly clean and usually requires no other treatment to fit it for human use.

Underground Tanks

This is also ideal for collecting rainwater. They are dug into the ground and creating a space that is designed to reduce water intrusion. To get the water out, pumps are used.

Underground tanks are great for harvesting rainwater because the rate of evaporation decreases because they are underground where sunlight does not actually penetrate.

Why Rainwater Harvesting Is Necessary

The collection of rainwater is very important for the people of all regions. It is great to end the fear of water scarcity in the future. The following points will help in understanding why rainwater harvesting is required:

• Surface water cannot meet the demand of water for various purposes.
• All are dependent on groundwater for all their needs.
• Due to deforestation, rapid urbanization, rainwater from the soil below the groundwater level is continuously decreasing.
• The level of water in natural water resources maintains rainwater storage.
• This reduces the risk of flooding on roads and the risk of soil wear and also improves water quality.

Conclusion

To overcome water scarcity, the surfaces of containers should be cleaned with the help of solid Co2 is used for this. Water harvesting helps in removing water scarcity as well as saving the environment.

Rainwater is used in homes and businesses, due to the rainwater harvesting system, we get fresh water anytime. Due to this, there is a reduction in the expenditure for the use of water, and it is ensured that water can be supplied to us as soon as possible at the time of need.
