Water scarcity is a major problem in some parts of India, but with the practical implementation of the Rainwater harvesting technique, we can tackle it. Moreover, it is very easy and simple that anyone can perform it. We must develop a habit of this technique to help people get access to pure water without any cost.

Importance of Rainwater Harvesting Essay

Importance of rainwater harvesting essay – The process of collecting and filtering rainwater, so that we can use it for our different kinds of chore works is known as Rainwater harvesting. Below are given the importance of rainwater harvesting

It saves time and money

As we know rainwater harvesting is a simple and easy method to save rainwater from wasting. And the best thing is that it is totally free, we have to pay no fee for it. Yes, if you opt and go for some advanced techniques to save water, it may cost you, but otherwise, it is free.

Also, the best advantage of rainwater harvesting is that it saves a lot of time as we do not have to use our continuous effort or time in order to save water. It is a one time process. After storing the rainwater, we can easily filter out the impurities from the rainwater and then use it for many purposes like – gardening, crop irrigation, etc.

It should be noted that water collected by rain is not fit for drinking but can be used for all other purposes.

Solution to the problem of water scarcity

Also as we discussed, water scarcity is going to be a major problem in the coming year. So, the best solution to this is Rainwater Harvesting.

Moreover, rainwater harvesting holds more capacity for holding and saving water. As we all are familiar with this fact that surface water is not enough to complete the demands of the people, we can get additional benefits from rainwater.

It maintains the Ecological Balance

Another importance of rainwater harvesting is that it maintains the ecological balance. By saving the rainwater, we can balance the ecology system. As you know, we humans waste tons of water daily and only 2.5 of earth’s water is left as freshwater. The rest is saline and ocean-based. Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields. 

In essence, only 0.007 percent of the planet’s water is available to fuel and feed its 6.8 billion people.

So by utilizing the rainwater, we can balance the ecology system. 

Reduce dependence and demand for Ground Water

Another great importance of rainwater harvesting is that it reduces the demand and dependence for ground and portable water. It is important especially in the area where the water level is very low.

Easy to Maintain and Eco Friendly 

Rainwater harvesting is a very efficient technique of conserving water. The preparatory model for rainwater conservation is very simple and economical too. Also storing water underground is eco-friendly. It reduces the impacts of flooding by funneling the off water into large tanks by recycling and helps minimize the load placed upon drainage systems.

Supplemental in Drought

Rainwater harvesting is very reliable and the best technique for countering situations like drought. Many of the countries, particularly those with arid environments, use rainwater for fulfilling their emergency needs. Whenever drought occurs, water stored by rainwater harvesting is used.

Important Methods of Rainwater Harvesting

Rain Barrels

It is the most simple and affordable method of rainwater harvesting. In this method, barrels or water tanks are installed below the downspouts of rooftops. And then the barrels or tanks are connected simply to our home which acts as a backup water system.

We can use it for all kinds of domestic purposes like – gardening, washing clothes, etc. Barrels and tanks are good equipment for storing rainwater.

Dry System 

The dry system is quite similar to the barrel system. However in the dry system, despite using barrels or tanks, a large storage container is used, which is installed usually a few meters away from the residential or commercial property.

Green Roof

In this method, water is channeled or passed straight to the garden, instead of storing water in a reservoir. The green roof method requires the installation of a drainage system on a building’s roof straight to the backyard. Although depicted as expensive, it is a very low maintenance method.

Disadvantage of Rainwater Harvesting

We have read many advantages of rainwater harvesting, but given below are some of the disadvantages of rainwater harvesting.

Unpredictable Rainfall

Very first disadvantage of rainwater harvesting is that of unpredictable rainfall.

Rainfall is quite hard to predict, and in some cases, little rainfall or no rainfall can limit the supply of rainwater.

Rainwater harvesting is practical and suitable only in those areas that receive a good amount of rainfall.

Storage Limits

Another disadvantage of rainwater harvesting is that of limited storage capacity as well as of limited rainfall. The collection and storage capacity may impose some kind of difficulties and restrictions. During heavy rainfall, the collection system may not be able to hold all rainwater.

Regular Maintenance

Rainwater harvesting systems heavily require regular maintenance, as they may get prone to insects, algae growth, etc, if not maintained properly. The system can become a shelter for many unwanted insects if again not properly maintained.

Conclusion – Rainwater Harvesting Essay

In the conclusion of this Rainwater harvesting essay in english or say the importance of rainwater harvesting essay, we can conclude that it is a very important tool to counter the situation of water scarcity for our future generation.

With its easy installment process and with proper maintenance we can save water and utilize it efficiently in our daily needs.
