Water scarcity is the most serious problem of today’s time in the last few decades and many countries of the world are facing this serious problem. Many people say that due to this scarcity of water, the next world war will be fought over water. So in today’s time governments all over the world are inventing new methods for water harvesting. And out of this, the best and most commonly used method is the rainwater harvesting system.
For rainwater harvesting, rainwater can be stored for future use and more and more rainwater can be saved. Rainwater harvesting is one such technique that is being adopted today in almost all the countries of the world. The water stored by this unique method is used for various purposes like horticulture, irrigation, etc.
In other words, it is the simplest system using which we can collect rainwater. Moreover, the rainwater harvesting system is so simple that it can be easily done by almost everyone at any place.
There are many places in India where there is a shortage of water. This system can be very beneficial to save water in such a place. Rainwater Harvesting A strategy to store rainwater using different methods in different places for future use (such as farming) is now being built in almost every city.
Rainwater can be collected very easily in any natural or man-made reservoir. The roof of our house is the best way for rainwater harvesting, in this way we can store that water very easily someplace. This method is very important in that areas of the world where there is less rainfall.
We can use this method to collect rainwater by creating a channel that leads to a storage facility such as a tank or pond. In this way, we can easily store a significant amount of water. In this way, we can later use the rainwater for various purposes.
By using the collected rainwater we can continue harvesting seasonal crops. And by filtering the rainwater, we can use it very easily in our daily work. Example for drinking, for cooking.
Importance of Rainwater Harvesting
Today rainwater harvesting has become very important due to the scarcity of water in many parts of the world. Rainwater harvesting is very easy and economical as compared to other methods. And there are many benefits of rainwater harvesting such as,
- Rainwater harvesting, or the right collection of rainwater, can solve the problem of water scarcity in many parts of the world.
- Even today, in many places, people depend only on groundwater for water and due to excessive use of groundwater, the level of groundwater has reduced significantly in the last few decades. Therefore, by using rainwater harvesting, we can maintain the level of groundwater to a great extent. This way, we can all use groundwater as it will continue to be replenished through rainwater harvesting. In addition, rainwater harvesting prevents waterlogging on the ground, thus reducing the chances of soil erosion.
- Rainwater harvesting helps in maintaining a healthy balance in the water cycle of our ecosystem. As you know, we humans waste so much water every day, so due to rainwater harvesting, the water cycle in our ecosystem remains in balance.
- Three-fourths of the earth is water, but only 1-2% of it is suitable for human consumption or agriculture. Many countries of the world still depend only on rain for agriculture. And these days, due to global warming, the rainfall has become quite erratic, and due to this, water is becoming increasingly scarce in many countries. Water harvesting is the best solution for those who depend on agriculture or generally live in drought-prone areas. Water harvesting is also the best solution for farmers who depend on the monsoon for continuous water supply.
- By collecting rainwater harvesting, we can use that water to overcome the water shortage in the future. And because of this, we do not have to depend on groundwater or river water.
Rainwater Harvesting Methods
- Rooftop Rain Water Harvesting (RRH): Rooftop water harvesting can be done easily in individual homes or schools. Rooftop rainwater harvesting involves allowing the portion of rainwater falling on the roof of a house to flow in a certain direction. The collected water can then be directly collected from the rainwater by placing a bucket or container under the roof.
- Underground tanks: Underground Tanks: These are constructed by digging a large space in the ground. Later cement is applied to prevent water from flowing. The rainwater is then discharged to the storage or to the ground through pipes directed into the tank. The water is then used to pump out the water using pumps.
What are the challenges faced in rainwater harvesting?
- Unexpected Rain: Predicting rainfall is very difficult to even today. And due to global warming, sometimes there is less rainfall or sometimes there is no rain, due to this, the supply of rainwater becomes very limited.
- Initial high cost: Depending on the size and technology level of the system, the cost of a rainwater harvesting system is high and its benefits may not be realized until it is fully ready for use.
- Regular Maintenance: Rainwater harvesting systems need to be maintained regularly.
- Storage Limitations: In rainwater collection and storage, we cannot store much rainwater. Its features may place limits on how much rainwater you can use. During heavy rains, the collection system cannot store the entire rainwater, as a result of which it flows into sewers and rivers.
FAQs for Essay on Rainwater Harvesting
Q 1. Why rainwater harvesting is important?
Answer: Rainwater Harvesting allows the collection of large amounts of water and mitigates the effects of drought. Almost every rooftop provides the necessary platform for collecting rainwater. Rainwater is mostly free from harmful chemicals, which makes it suitable for agriculture and irrigation purposes.
Q 2. How do you explain rainwater harvesting?
Answer: Rainwater harvesting is the collection and storage of rainwater that runs off from rooftops, parks, roads, open grounds, etc. This water runoff can be either stored or recharged into the groundwater.
Q 3. Which country has immense draught problems?
Answer: African countries such as Kenya and Sudan have extreme drought problems.
Q 4. Should rainwater harvesting be made compulsory?
Answer: Rainwater harvesting should be made compulsory for companies and big factories.
